[00:03] <mjrosenb> while we're on the topic of 13.04, is there a reasonable upgrade path to 13.04 from the haked-sh-script installation for the chromebook?
[00:31] <Ethernin> KDE-plasma on the Nexus7....here we go!
[00:31] <Tassadar> oooh, craaap
[00:31] <Tassadar> i missclicked and started eclipse
[00:31] <Tassadar> it will take ages to launch and ages to shutdown again :(
[00:31] <Ethernin> hahaha
[00:32] <Ethernin> fuck booted me back into unity
[00:33] <Ethernin> standby
[00:33] <Ethernin> kdm is nice tho ^_^
[00:35] <Ethernin> not bad....not bad
[00:36] <Ethernin> yeah just like i thought
[00:36] <Ethernin> it's too much for it to handle off the bat
[00:36] <Ethernin> needs some tweaking
[00:36] <Tassadar> KDE had some project to bring plasma to mobile devices too, hadn't it?
[00:36] <Ethernin> some of the gestures are working at least
[00:36] <Ethernin> yeah i think it was plasma 3?
[00:42] <Ethernin> good god kde-plasma is buggy on this
[00:42] <Ethernin> RATS
[00:43] <Ethernin> looks nice tho...
[00:43] <Tassadar> yeah, that's KDE ^^
[00:43] <Ethernin> kinda figured as much....
[00:43] <Ethernin> i guess ill try kubuntu now
[00:44] <Ethernin> i just want something that works....
[00:44] <Ethernin> or can work...
[00:44] <Ethernin> i hate how normal hotkeys dont work in kde...
[00:44] <Ethernin> crtl alt T for instance...
[00:46] <Tassadar> what should that do?
[01:33] <Ethernin> Tassadar, open a terminal
[01:43] <Daughain> Has there been any work porting ubuntu to the Qualcomm chipsets?
[01:44] <infinity> We don't ship any Qualcomm kernels, no.
[01:44] <infinity> If you happen to have one handy, the userspace will all Just Work.
[01:45] <Daughain> Thanks, is there a link for editing kernels?
[01:45] <Daughain> Existing
[01:45] <infinity> No idea.
[01:46] <infinity> See above, re: we don't ship any.
[01:46] <infinity> If your device ships with an Android kernel, our userspace would work with that.  Or if the device or SoC manufacturer offer a BSP, or if Linaro has a kernel for that SoC, etc...
[01:48] <Daughain> Ok, I'm trying to find a way to run ubuntu as a dual boot, rather than a chroot. Any ideas here I should look to accomplish this?
[01:49] <infinity> I honestly have no clue.  Every device is (very) different, and I have no QC-based devices.
[01:49] <Daughain> Here==where
[01:50] <Ethernin> Daughain, i've been interested in the same thing for sure, have you tried recompiling the android kernel with more options for linux?
[01:50] <Daughain> Actually, I don't care if it dual boots, or just boots ubuntu. Either will work.
[01:50] <Daughain> Ethernin: can't compile anything right mow.
[01:51] <Ethernin> Daughain, yeah i was trying to get a desktop environment to boot instead of using vnc, doesn't work very well
[01:51] <Daughain> I'm trying to learn what has been done, and how much work I need to do to get cli
[01:52] <Ethernin> infinity, do you know if Ubuntu is being developed for android phones?  sorry if that's already been asked
[01:52] <Ethernin> Daughain, right, running full linux kernel and not chroot
[01:52] <Ethernin> I've been trying to figure out the same thing, haven't had much luck
[01:53] <infinity> Ethernin: Same answer as above.  We don't currently ship any kernels for any Android phones, but the userspace works fine with the Android kernels (and works better if you recompile with some extra bits turned on, as you've noted).
[01:54] <infinity> The closest we come is the Nexus7 tablet, which there's been much ado about us using as a reference platform for slate devices.
[01:54] <Ethernin> infinity, cool thanks, as far as recompiling the kernel for android, have you been able to get the proper sources and headers that match the android 3.0.8 kernel?
[01:55] <Ethernin> infinity, or just get as close as you can?
[01:55] <Daughain> Ok, thanks a lot guys, I need to do some more research....
[01:55] <Ethernin> good luck, report back!
[01:56] <infinity> The two Android kernel sources we ship are both at 3.1.10
[01:56] <Ethernin> ok roger
[01:56] <infinity> (ac100 and nexus7)
[01:56] <infinity> Both based on NVIDIA Tegra BSPs.
[01:56] <infinity> Every SoC vendor has their own blessed tree, sadle.
[01:56] <infinity> s/sadle/sadly/
[01:56] <Ethernin> riiiiiiiiiiiiiiiiiight
[01:56] <Ethernin> ok
[01:57] <Ethernin> so for instance trying to recompile the kernel on a samsung galaxy S3 wouldn't really work unless the kernel version was 3.1.10?
[01:57] <infinity> I'm kinda hoping (though not holding my breath) that the combination of more Android patches being mainlined, and Arnd's work toward single zImage in mainline might mean that the BSP madness can eventually come to an end.
[01:57] <infinity> But, y'know, that'll still be years in the making. :/
[01:57] <Ethernin> infinity, :(
[01:57] <Ethernin> infinity, it's too bad, yet another reason why the N900 kicked so much ass
[01:58] <infinity> Ethernin: Hrm?  No, what you'd need is a kernel tree that actually supports the S3, version is less relevant.
[01:58] <Ethernin> infinity, really hope the guys at jolla come out with the next version
[01:58] <Ethernin> infinity, ok hmm
[01:58] <infinity> I mean, we're shipping nexus7 sources at 3.1.10, but our mainline kernels are 3.7... Clearly, we don't care much about versions. :P
[01:59] <Ethernin> infinity, last time i looked at recompiling the android kernel on the SGS3 I ran into problems trying to find the headers and source that matched the kernel version, but I think I see what youre saying
[01:59] <Ethernin> lol right on
[02:02] <Ethernin> infinity, so any advice to get gestures working on the Nexus7 ?  I'm looking into utouch / multitouch and magick-rotation - I'm finding unity is deathly slow, XFCE and LXDE work pretty darn fast tho
[02:03] <Ethernin> infinity, gnome-fallback (classic) works pretty awesome but trying to make icons bigger and get single touch to open icons has been next to impossible with whats on there to begin with
[02:04] <Ethernin> infinity, anyway any advice in that direction would be greatly appreciated!
[02:04] <Ethernin> I also just tried kde-plasma but all kinds of problems there
[02:05] <infinity> Ethernin: I'm more of a low-level guy.  Asking me for advice with GUIs is like asking a physicist to perform neurosurgery.  I kinda know how it all works, but you don't want me mucking around in there.
[02:05] <Ethernin> infinity, hahaha lol fair enough, im the same way that's why I'm looking for help!  :P
[02:06] <Ethernin> I've got all the CLI tools and everything I need installed, it's just making it point and click now...
[02:27] <achiang> Ethernin: we support some gestures today, the non-working gestures are either bugs or unimplemented
[02:27] <achiang> Ethernin: for instance, 3-finger tap works (to display unity drag handles). 4-finger tap to display dash works too
[02:28] <Ethernin> AWESOME!
[02:29] <Ethernin> achiang, thank u!  I found the 3-finger, but like no desktop switching??
[02:29] <achiang> Ethernin: i don't know what that gesture is (but could find out tomorrow)
[02:29] <achiang> Ethernin: if you're into hacking multitouch, we'd love to see such patches
[02:30] <Ethernin> omg hell yes
[02:31] <Ethernin> achiang, that's my plan, I've recompiled the kernel with a wizard friend and have all the usb host mode packet injection support i need, plus ubertooth!  but really it's just making the desktop usable
[02:31] <Ethernin> onboard is pretty frustrating as well, I compiled florence keyboard which is pretty nice, but they're all super buggy and hard to use well
[02:31] <achiang> Ethernin: are you on the quantal image or raring image?
[02:32] <Ethernin> both - I have a 16GB nexus 7 running 12.10 and a 32GB with 3G running the latest Raring
[02:32] <Ethernin> reverse shells over the 3g was also in the plans
[02:32] <achiang> Ethernin: onboard in the raring image is not so bad
[02:32] <Ethernin> my goal is to create a nice easy-to-use pentesting platform and release it to the public after completed
[02:33] <Ethernin> yeah it's definitely better than on quantal
[02:33] <Ethernin> achiang, I really APPRECIATE all the work you guys have done getting Ubuntu working on the device
[02:34] <Ethernin> honestly I was going for an android phone but no one has really made full linux available for android phones that isn't some kind of chroot env ect
[02:34] <achiang> Ethernin: well, the rest of the team isn't here to accept the kudos but i'll certainly be happy to pass them on. :)
[02:35] <Ethernin> achiang, haha thanks man, it's really awesome to see ubuntu running on these small devices!
[02:35] <Ethernin> achiang, I will be mainly working on selecting the right desktop environment for the Nexus7 (probably LXDE or XFCE because they run the fastest) and getting all the multitouch stuff to work
[02:36] <Ethernin> I have a few people helping me, and would be happy to share/upload my results at the end of the week
[02:36] <achiang> Ethernin: i'm mostly a paperpusher, but if you want need help getting people to pay attention to your work, give me a poke
[02:36] <Ethernin> don't know where to send that stuff but maybe I'll just throw it in dropbox or something
[02:36] <Ethernin> for sure man!
[02:37] <achiang> Ethernin: fwiw, lxde/xfce will respond differently to multitouch than default compiz+unity
[02:39] <Ethernin> achiang, word thanks for that info,
[02:39] <achiang> Ethernin: not sure how those desktop environments respond to MT and/or gestures... also for unity, we at least have a spec for what *should* happen
[02:39] <achiang> (but everyone is of course free to choose their own desktop environment)
[02:39] <Ethernin> is there any documentation for that available?
[02:39] <achiang> let me go digging
[02:40] <Ethernin> achiang, well honestly I would love to use unity if it was faster, 2d was at least a little quicker and one of the main issues I've had is not being able to open desktop icons with one tap!!  and there's nowhere to change the mouse option to "1 click to open"
[02:40] <Ethernin> achiang, awesome thanks man!
[02:41] <achiang>  Ethernin send me an email, i can't find it atm
[02:42] <Ethernin> achiang, k roger, thanks a lot man!
[02:43] <achiang> Ethernin: cool, look what i found https://wiki.ubuntu.com/Multitouch
[02:43] <achiang> i'll try and find a list of the unimplemented ones tomorrow
[02:45]  * achiang goes to dinner
[02:45] <Ethernin> achiang, awesome thanks again!

[06:39] <raster> diwic: YO! the man i wanted to see!
[06:39] <diwic> raster, hi
[06:39] <raster> :)
[06:39] <raster> sound guru...
[06:39] <raster> nexus 7
[06:39] <raster> point me at some info/docs/something... i can use.. to get my audio to work! :)
[06:40] <diwic> raster, bug 1068804 ?
[06:40] <ubot2`> Launchpad bug 1068804 in ubuntu-nexus7 "sound only works after suspend/resume cycle" [Critical,Confirmed] https://launchpad.net/bugs/1068804
[06:40] <raster> i know
[06:40] <raster> nup - donest help
[06:40] <raster> (suspend/resume dont fix anything - not even several cycles)
[06:40] <diwic> raster, hmm, interesting
[06:40] <raster> my initial problem was /dev/sdn/* permissioning
[06:41] <raster> ie my uid didnt have access
[06:41] <raster> so pulse couldnt talk
[06:41] <raster> and all i got was "dummy output" in pulse
[06:41] <diwic> raster, are you doing something custom, i e not ubuntu image?
[06:41] <raster> i figured that out
[06:41] <raster> and then pulse detects the tegra hw device
[06:41] <raster> ubuntu image...
[06:41] <raster> BUT... i nixed the desktop
[06:41] <raster> all system daemons working
[06:41] <raster> pulse still there
[06:42] <raster> desktop does handle pulse audio
[06:42] <diwic> raster, what does "nixed the desktop" mean?
[06:42] <raster> i have installed pavucontrol
[06:42] <raster> and that lets me diagnose soem stuff anf fiddle
[06:42] <raster> nixed - dont run unity (compiz+gnome bits etc.)
[06:43] <raster> nicex lightdm
[06:43] <raster> nixed lightdm
[06:43] <raster> (uninstaleld it - use nodm instead)
[06:43] <raster> my mem footrpint is down to like 160m ram
[06:43] <raster> as a result
[06:43] <raster> (total excluding buffers/cache)
[06:44] <raster> less actually
[06:44] <diwic> raster, do you still use consolekit to give you permissions to everything you should?
[06:44] <raster> 131m "userspace" from smem -t
[06:44] <Ethernin> raster, question is pavucontrol the desktop environment or are you going cli only?
[06:45] <raster> no
[06:45] <raster> but what do i need permission to other than pulseaudio server?
[06:45] <raster> i can get audio going through it
[06:45] <raster> it just ends up "nowehre"
[06:45] <raster> also i just chowned /dev/snd/* to myselfg anyway
[06:45] <raster> that was the perms problem
[06:45] <raster> Ethernin:  pavucontrol is in the gui (desktop)
[06:46] <raster> but tbh - dont care
[06:46] <raster> cmdline will be fine
=== zz_chihchun is now known as chihchun
[06:46] <Ethernin> raster, are u using gnome-classic (fallback?)
[06:46] <raster> no
[06:46] <raster> e17
[06:46] <raster> :)
[06:46] <raster> compositing is all happy
[06:46] <Ethernin> word
[06:46] <raster> suspend/resume all happy
[06:46] <Ethernin> hahaha nice
[06:46] <diwic> raster, I guess /dev/snd/* should be enough (together with some /sysfs stuff).
[06:46] <raster> i'm a bit miffed at the nvidia drviers not doing vsync swaps
[06:46] <raster> even tho swapinterval is requested to be 12
[06:46] <raster> err 1
[06:47] <raster> diwic: well i thought /dev/snd would be enough
[06:47] <raster> if there is something needing a write.. who would be doing it? pulse?
[06:47] <raster>  /sys is there - but of course readable only- not write
[06:48] <raster> i can hunt it down if my hunting fields are.. sensible :)
[06:48] <raster> i hear u are the guru fo sound so you probably would know what it might be :)
[06:48] <raster> i';ve never had this problem before on any ubuntu x86 install
[06:48] <diwic> raster, but the entire suspend/resume thing is a mystery to me. It might be that something is triggered when unity unsuspends but not when your system unsuspends.
[06:48] <raster> i've nuked unity/gnome/etc over the years and never hit a sound snag
[06:48] <raster> pulseaudio has always worked
[06:48] <raster> so what is different about the n7 compared to other ubuntus?
[06:49] <diwic> raster, the sound chip is different.
[06:49] <raster> e17 has pulseaudio mixer support - we even "reverse engineered" pa protocol in order to provide a working pa mixer without needing libpulse
[06:49] <raster> hahaha
[06:49] <raster> sure :)
[06:49] <raster> its different
[06:49] <raster> but what about access/permissioning is different?
[06:50] <diwic> raster, desktop machines use 100s of variants of Intel HDA, whereas the n7 uses tegra 3 + realtek alc5640
[06:50] <raster> ie - it goes via alsa.. so /dev/snd/* should be enough
[06:50] <raster> what ELSe is there? :)
[06:50] <raster> sure
[06:51] <diwic> raster, if it looks like sound is muted even though you have unmuted it (in PulseAudio, with my nexus7 profile), it's the same symptom as the suspend/resume bug.
[06:51] <raster> i'm happy to learn - this is not my specialty... so if there is some info/docs i can scour... i'd be more than happy to figure it out :) right now picking your brain is the next best step :)
[06:51] <raster> soudns LOOKS unmute3d
[06:52] <raster> according to e17's mixer and pavucontrol
[06:52] <diwic> raster, you have the ubuntu-defaults-nexus7 (or was it ubuntu-nexus7-defaults) installed, don't you?
[06:52] <raster> alsamixer (when run as root) gives me like 27842 controls
[06:52] <raster> i have been fiddling with everyone i can find
[06:52] <raster> i did notice one of them was muted by default after a boot
[06:52] <raster> that may be a cause of your suspend/resume issue
[06:53] <raster> yup
[06:53] <raster> installed
[06:53] <raster> i havent messed with any of those
[06:53] <raster> nb - awesome job getting ubu up on the n7 so far
[06:53] <raster> it made my life SO easy
[06:54] <raster> compared to what it normally is with arm targets
[06:54] <raster> its CLOSE to perfect
[06:54] <diwic> raster, if you've messed around with the alsamixer controls maybe you happened to turn one off that should have been on, or the other way around?
[06:54] <raster> multitouch for me works outof the box
[06:54] <raster> literlaly i can pinch/zoom/rotate in my toolking/apps out of the box
[06:54] <raster> just works (tm)
[06:54] <raster> well iv'e rebooted since i messed
[06:54] <raster> several times
[06:54] <raster> they reset to defaults on reboot
[06:55] <diwic> raster, hmm, are they? I thought they were saved in .. /var/lib/asound.state
[06:55] <diwic> or something like that
[06:55] <raster> nup
[06:55] <raster> last i knew it saved in ~/.asounrc or something
[06:56] <raster> ~/as...
[06:56] <diwic> do you have a custom .asoundrc too?
[06:56] <raster> no
[06:56] <raster> hmm
[06:56] <raster> /var/lib/alsa/asound/state is there
[06:56] <raster> ok
[06:56] <raster> thats a new file
[06:57] <raster> oh please dont telll me its that
[06:57] <raster> i swear i rebooted and mixer vals were reset from the mess i made
[06:57] <raster> i cant chekc right now.. as i'm sshing like 1500km to get to my n7
[06:58] <diwic> bbiab
[06:58] <raster> its speakers are not loud enough to hear that far
[06:58] <raster> :)
[06:58] <raster> i can check tonight tho
[07:13] <diwic> raster, I mean, the suspend/resume thing is a mystery to me, and chances are that when you switch desktops the bug might manifest itself differently, in which case I don't know what to do to help you
[07:16] <raster> hmm
[07:16] <raster> :(
[07:16] <raster> any info i can read up on what's invovled in sound output on the tegra?
[07:16] <raster> (and alsa/kernel etc.)
[07:17] <raster> any specific /sys nodes involved?
[07:17] <raster> any info on what all the alsa mixer control knobs really do?
[07:17] <raster> in fact.. what did you have to do to get it to work?
[07:31] <dholbach> good morning
[07:32] <raster> moo
[07:32] <dholbach> just installed raring on the Nexus7 and things are looking quite good :)
[07:32] <raster> gl isnt totallly busted anymore?
[07:32] <raster> it was end of last week when i tried the 13.04 image
[07:33] <dholbach> raster, do you have a bug number about this? what was the problem you were looking at?
[07:33] <raster> all garbaged up tiles in unity for compositor pixmaps
[07:33] <raster> no i dont
[07:33] <dholbach> no, that's fixed
[07:33] <dholbach> a new unity+friends landed
[07:33] <raster> oh ok
[07:33] <dholbach> we were waiting for a fix in the nux library for a long while
[07:34] <raster> i saw that and then went to the 12.10 image
[07:34] <raster> which works fine
[07:34] <dholbach> but it couldn't land due to some other issues - in any case it's in there now
[07:34] <raster> does this have an update to the gles driver stuff from nv?
[07:34] <raster> as the lack of vsynced swaps is most annoying
[07:34] <raster> i'm wodnering if thats been fixed
[07:34] <dholbach> good question - I don't know
[07:35] <raster> and i have a sneaking suspicion that that its doing back -> front buffer copies, not swaps/exchanges
[07:35] <raster> well if u move a window.. do u get tearing?
[07:36] <raster> tho last i read compiz code.. it tyried to do glcopypixels from back to front bvuffer
[07:36] <raster> which wouldnt help with that
[07:36] <raster> but if u do eglswapbuffers it tears
[07:36] <raster> aat the compositor level - so i know its not vsyncing even tho its been asked to do a swapinterval of 1
[07:45] <raster> i'm just wondering if its better to perhaps file bugs with nvidia over these things instead
[07:45] <raster> as i know canonical just consume the drivers "as provided"
[07:46] <raster> tho i need to get all my niggly issues fixed up before i go filing bugs...
[07:46] <raster> i dont like to file a bug until i'm sure of it :)

[12:01] <dholbach> all right, my ARM friends - who of you is going to give a demo or talk at Ubuntu Developer Week? We still have a bunch of open slots: https://wiki.ubuntu.com/UbuntuDeveloperWeek/Timetable
[12:01] <dholbach> if you want you can just take a 30m slot and talk about something more specific if you like
[12:01] <dholbach> but I think it'd be great to have some ARM/device/memory/power/IO content in there as well
[13:13] <hrw> I hate when it happen

[13:40] <raster> diwic: my many thanks
[13:40] <raster> it was that asound file
[13:40] <raster> must have been from my messing when pulse still had dummy output only
[13:40] <raster> trying to get it to work
[13:40] <raster> (ie permissions problem)
[13:40] <raster> i fixed perms - but still had that around
[13:40] <raster> much thankinessess :)
[13:40] <diwic> raster, glad it helped :-)
[13:41]  * raster owes diwic a beer
[13:42] <raster> i now really wish i knew what all these mixer params did in alsa
[13:42] <raster> theres so many of them
[13:42] <raster> :)
[13:44] <diwic> raster, but you're still having the suspend/resume problem like the rest of us, right?
[13:45] <raster> yup
[13:45] <raster> needs a suspend/resume cycle
[13:45] <raster> that.. i can live with.. for now
[13:45] <raster> :)

[16:35] <tassadar_> sudo passwd root should work(?)
[16:35] <cortexA9> no..
[16:36] <tassadar_> ou, guest session, right, sorry
[16:36] <cortexA9> how to log in ?
[16:36] <cortexA9> i have only guest session
[16:36] <cortexA9> :(
[16:38] <cortexA9> very strange..
[16:38] <tassadar_> dunno, I can't even finish the "setup wizard" on 13.04, because the onboard does not show up and keyboard via OTG does not work (but I think that's keyboard's fault)
[16:39] <cortexA9> oh i downloaded preinstalled img
[16:39] <cortexA9> and now i am in the desktop
[16:39] <tassadar_> from where?
[16:39] <cortexA9> i have all
[16:39] <cortexA9> nexus 7
[16:40] <cortexA9> oh the img ?
[16:40] <cortexA9> you mean ?
[16:40] <tassadar_> yeah
[16:40] <infinity> cortexA9: First boot on the preinstalled image walks you through creating a user.
[16:40] <cortexA9> mmm..
[16:40] <cortexA9> i dont have this
[16:40] <infinity> (modulo the bug tassadar mentions)
[16:40] <tassadar_> initramfs-tools package is the the same for nexus 7 as is for the rest of ubuntu, right?
[16:40] <infinity> tassadar_: Yes.
[16:41] <infinity> tassadar_: Why do you ask?  (I'm upstream for it)
[16:41] <cortexA9> i think the img
[16:42] <cortexA9> i dont know..
[16:42] <cortexA9> was a mirror
[16:42] <tassadar_> I'd like to add support for booting from some folder in root (with mount -o bind), it is a short patch, gimme a while and I show you what do I mean
[16:42] <cortexA9> daily i think..
[16:43] <cortexA9> i tried with multirom
[16:43] <cortexA9> to add it..
[16:43] <tassadar_> isn't it 12.10?
[16:43] <cortexA9> no 13.04
[16:43] <tassadar_> well, multirom should not work with 13.04
[16:44] <cortexA9> why not ?
[16:44] <cortexA9> it seems work..
[16:44] <cortexA9> only i can't log in with root..
[16:44] <cortexA9> just this
[16:44] <tassadar_> how did you even install it?
[16:45] <cortexA9> i decompress it
[16:45] <cortexA9> and changed raw to img
[16:45] <cortexA9> and work..
[16:45] <tassadar_> are you sure that boot.img is correct?
[16:45] <cortexA9> mmm i dont know
[16:46] <cortexA9> maybe is the 12.10 boot ?
[16:46] <tassadar_> yeah
[16:46] <tassadar_> do uname -a
[16:46] <tassadar_> and tell me what does it says
[16:47] <cortexA9> Linux localhost.localdomain 3.1.10-7-nexus7 #11-Ubuntu SMP PREEMPT Tue.. armv7l ...
[16:48] <tassadar_> hmm, sorry, I thought I'd remember which one is 13.04, I _think_ it should be -8-
[16:48] <tassadar_> can you do...
[16:48] <tassadar_> cat /boot/config* | grep HARDBOOT
[16:48] <tassadar_> I hope it is accessible without root
[16:49] <cortexA9> mmm
[16:50] <tassadar_> nothing?
[16:50] <cortexA9> no such file or directory
[16:50] <cortexA9> i need to inject boot.img ?
[16:50] <cortexA9> in multirom ?
[16:50] <tassadar_> is config-somethingIdontRemember file in your /boot folder?
[16:51] <tassadar_> no, this should be part of ubuntu
[16:51] <cortexA9> permission denied
[16:51] <cortexA9> damn
[16:52] <tassadar_> yeah, got it, you are using 12.10 boot.img
[16:52] <tassadar_> it should be "3.1.10-8-nexus7"
[16:52] <cortexA9> mmm ok
[16:52] <cortexA9> i inject the new boot thanks
[16:53] <tassadar_> there is "Add/change boot.img" option in recovery in "list roms" menu
[16:53] <tassadar_> in puts the boot.img in right place and injects it
[16:53] <cortexA9> yes
[16:54] <tassadar_> infinity: http://pastebin.com/siEiZPJz something like this
[16:58] <cortexA9> tassadar_: i need to rename it ?
[16:58] <tassadar_> ?
[16:58] <cortexA9> in boot.img ?
[16:58] <tassadar_> what rename?
[16:58] <cortexA9> the file
[16:58] <tassadar_> which one)
[16:58] <cortexA9> raring-preinstalled-desktop-armhf+nexus7.bootimg
[16:59] <tassadar_> yeah, recovery searches for files which end with ".img"
[17:01] <cortexA9> tassadar_: it failed..
[17:01] <cortexA9> file raring-preinstalled-desktop-armhf+nexus7.boot.img
[17:01] <cortexA9> i renamed it..
[17:02] <tassadar_> what does recovery log says, adb shell into it and cat /tmp/recovery.log
[17:02] <infinity> tassadar_: Curious.  Does this actually work?
[17:02] <tassadar_> yed
[17:02] <tassadar_> yes
[17:03] <tassadar_> I'm using it to multiboot ubuntu on n7
[17:03] <tassadar_> along with kexec and "export FLASH_KERNEL_SKIP=1", it is the only thing I need to change in ubuntu, which is kinda amazing Oo
[17:04] <cortexA9> failed to decompress ramdisk
[17:05] <tassadar_> oh, yeah, the ramdisk is compressed with .lzma instead of .gz
[17:05] <tassadar_> see, that's why it is unsupported :D
[17:05] <cortexA9> lol
[17:05] <tassadar_> you could compress it as gzip on computer if you want
[17:06] <cortexA9> oh mmm
[17:06] <tassadar_> I am working on v3 which will support 13.04, it should be out this week
[17:07] <cortexA9> tassadar_, you are the developer of multirom ?
[17:08] <tassadar_> yes
[17:08] <cortexA9> oh nice :)
[17:09] <tassadar_> it is actually already all working, I just need to change the recovery and I'd like to try to get the changes into official ubuntu packages
[17:10] <cortexA9> how to open it ?
[17:10] <cortexA9> 7zip can't open it.
[17:11] <tassadar_> are you on ubuntu?
[17:11] <cortexA9> no atm no.
[17:11] <tassadar_> you know what, just wait, I'll edit it, it'll be faster
[17:12] <cortexA9> ok
[17:12] <cortexA9> :)
[17:14] <cortexA9> tassadar_: work now
[17:14] <cortexA9> i have the gz
[17:14] <cortexA9> wait
[17:15] <cortexA9> :D
[17:16] <tassadar_> okay)
[17:16] <tassadar_> just finished the editing too)
[17:17] <tassadar_> infinity: what do you think, should I submit it as a patch?
[17:17] <tassadar_> "should" as in "is it even worth the trouble?"
[17:19] <infinity> tassadar_: Submitting it as a Debian bug report might be nice.  I'll likely forget about it otherwise.
[17:19] <infinity> tassadar_: Assuming this is a feature you can envision people other than you wanting.
[17:22] <tassadar_> well, i suppose it would make multi-booting ubuntu on other android devices easier, but on desktop it is probably useless
[17:22] <tassadar_> booting from .img is already there though, but I guess that is used mainly in that "Install ubuntu as windows app" thing
[17:23] <[mbm]> wubi
[17:25] <tassadar_> that is just in the ubuntu's initramfs-tools, not in debian, I think I should submit it just to ubuntu
[17:26] <cortexA9> tassadar_: it's possible that multirom slow my system ?
[17:27] <tassadar_> which part exactly?
[17:27] <cortexA9> usb very slow
[17:27] <cortexA9> it really slow now..
[17:27] <tassadar_> like what, you are in ubuntu and copying something from usb or what?
[17:28] <cortexA9> no in the rom
[17:28] <cortexA9> copying something
[17:28] <cortexA9> from pc to tablet
[17:29] <tassadar_> hmm, look into battery usage, is "media" in there?
[17:29] <cortexA9> yes
[17:29] <tassadar_> android scans the /sdcard for media files after boot, and well, it scans also the whole of ubuntu (it is in /sdcard), which is a lot of files
[17:30] <cortexA9> oh ok
[17:30] <[mbm]> .nomedia
[17:30] <tassadar_> it _should_ finish 15-30mins after boot though
[17:30] <tassadar_> it ignores it
[17:30] <tassadar_> gallery does not show images from that folder, but the media scanner still goes in there
[17:31] <cortexA9> i can't force stop.
[17:31] <cortexA9> :D
[17:31] <tassadar_> you could kill it if you want, but I dunno if that does not break something
[17:32] <tassadar_> (in shell via "kill" command I mean)
[17:34] <cortexA9> with advanced task killer doesnt work :D
[17:34] <cortexA9> ok i try in shell
[17:36] <cortexA9> i need to root it :D
[17:36] <cortexA9> for kill
[17:37] <tassadar_> you what....
[17:37] <tassadar_> you don't have it rooted yet? Oo
[17:38] <cortexA9> no because i have problem with the battery today
[17:40] <cortexA9> today my battery was at 0%
[17:40] <cortexA9> i thought my nexus 7 dead..
[17:41] <cortexA9> now seems work
[17:41] <tassadar_> wau, okay, that is reason serious enough)
[17:42] <cortexA9> it's called
[17:42] <cortexA9> mediaserver right ?
[17:42] <cortexA9> the process ?
[17:42] <infinity> tassadar_: You can submit to whomever you like, I maintain it in both Debian and Ubuntu. :P
[17:43] <tassadar_> uh, it's the one which takes most cpu power, that is how I always find it
[17:43] <tassadar_> infinity: okay, creating bug report on launchpad right now
[17:46] <tassadar_> okay, english grammar question:) "Whose phone is that?" - the "whose" is for human beings, what is the same word for things?
[17:47] <dtchen> likely "those"
[17:47] <dtchen> I suppose it depends on the part of speech
[17:47] <cortexA9> lol
[17:47] <cortexA9> tassadar_: i kill it
[17:48] <cortexA9> but it appear..
[17:51] <cortexA9> mmm
[17:51] <cortexA9> seems not this the problem.
[17:52] <tassadar_> are you on windows or linux?
[17:52] <cortexA9> win
[17:53] <cortexA9> it's not a problem of multirom ?
[17:54] <tassadar_> to be honest, I don't know. I don't use windows, but I don't think the problem is in multirom. You could try asking in the XDA thread...
[17:55] <tassadar_> Are you copying like a big file, or bunch of smaller ones?
[17:55] <cortexA9> 6 mb..
[17:55] <cortexA9> maybe is win
[17:55] <cortexA9> try to reboot
[17:55] <cortexA9> see you
=== shadeslayer is now known as buildslayer
[18:01] <tassadar_> infinity: I also need to "export FLASH_KERNEL_SKIP=1" when booting, where is the best place to do it? Would new script in scripts/init-top which would simply call "export FLASH_KERNEL_SKIP=1" work?
[18:03] <cortexA9> tassadar_: it's win now work
[18:03] <cortexA9> but i can't inject boot.img
[18:03] <cortexA9> i compress with gzip
[18:04] <tassadar_> you need to extract the boot image, extract ramdisk, repack it, and repack the boot image)
[18:04] <cortexA9> oh..
[18:04] <cortexA9> lol
[18:04] <tassadar_> ...so, I get that you wanna that repacked image I just made)
[18:04] <cortexA9> i thought it's simple
[18:04] <cortexA9> :D
[18:05] <tassadar_> if only I'd remeber in which of the terminal tabs it was...
[18:05] <tassadar_> ah, here
[18:05] <cortexA9> what ?
[18:05] <cortexA9> you have a repacked image ?
[18:06] <tassadar_> nothing, here you go http://dl.dropbox.com/u/54372958/boot-raring-gz.img
[18:06] <infinity> tassadar_: Eh?  Why would you need it while booting?
[18:07] <infinity> tassadar_: If your boot process (or ours) is calling flash-kernel, that's a bit odd.
[18:07] <tassadar_> installer calls it
[18:08] <infinity> tassadar_: Oh, sure, that's a different story.  That means our installer isn't quite right for your setup, that's all.
[18:08] <cortexA9> lol
[18:08] <tassadar_> I will probably not use the installer though, so, it really is enough to do it after boot
[18:08] <tassadar_> where would be the appropriate place to do it?
[18:09] <tassadar_> (somewhere where no package will overwrite it)
[18:09] <cortexA9> tassadar_: how you can do multirom :D
[18:09] <cortexA9> i am curious
[18:10] <infinity> tassadar_: You should just remove flash-kernel, if it doesn't do the right thing for your setup.
[18:10] <infinity> tassadar_: Hacking around it is silly.
[18:10]  * tassadar_ slaps himself
[18:11] <tassadar_> forgot it is just package like everything else, so apt-get purge flash-kernel, nice :)
[18:11] <tassadar_> cortexA9: what? Oo
[18:11] <cortexA9> yes
[18:11] <cortexA9> i mean
[18:11] <cortexA9> multirom it's hard to make it ?
[18:12] <tassadar_> the idea is simple, the hard thing is to make it nice and easy to use for the "average android root user"
[18:12] <cortexA9> :)
[18:13] <cortexA9> lol
[18:13] <cortexA9> i inject it
[18:13] <cortexA9> thanks
[18:13] <cortexA9> now i try
[18:13] <tassadar_> I think the main difference is the graphical boot menu, I did not see that in any other multi boot mod on XDA
[18:14] <cortexA9> damn
[18:14] <cortexA9> it not boot..
[18:14] <cortexA9> lol
[18:14] <tassadar_> does it say anything?
[18:14] <cortexA9> yes
[18:15] <cortexA9> error no tarball found
[18:15] <cortexA9> did you use the right rootfs.img
[18:15] <cortexA9> ?
[18:15] <cortexA9> it say
[18:15] <tassadar_> there is no tarball because it is already installed, I hoped it would just print the error and continue on, but apparently not
[18:16] <tassadar_> gimme a while
[18:16] <cortexA9> ok
[18:18] <gurgalof> sudo fastboot flash userdata raring-preinstalled-desktop-armhf+nexus7.img
[18:18] <gurgalof> takeswaay too long time
[18:19] <gurgalof> gets stuck at sending 'userdata' (728117 KB)...
[18:19] <gurgalof> i tried to make at image for 32GB nexus7
[18:20] <cortexA9> guys i think one thing
[18:20] <cortexA9> thinking
[18:20] <Ethernin> lol
[18:21] <tassadar_> gurgalof: fastboot has problems flashing files that big
[18:21] <gurgalof> how did nexus7-installer do it with quantal?
[18:22] <tassadar_> I think -S 600M switch could help with that...?
[18:22] <tassadar_> the images were smaller
[18:22] <gurgalof> there was an image for the 32GB one...
[18:22] <tassadar_> cortexA9: http://dl.dropbox.com/u/54372958/boot-raring-gz2.img
[18:22] <gurgalof> -S 600M on what?
[18:23] <cortexA9> tassadar_: thanks
[18:23] <tassadar_> fastboot -S 600M flash userdata ..., but I am not sure it was exactly that, I did not try it
[18:26] <kulve> I think the -S doesn't work with nexus 7
[18:27] <tassadar_> yeah, people who were trying it said it mostly does not work
[18:27] <kulve> I didn't succeed even once.. I tried quite many times
[18:27] <tassadar_> if you have just root.tar.gz in that image, I would just copy it via recovery
[18:28] <cortexA9> tassadar_: no init found
[18:28] <cortexA9> try passing init=bootarg.
[18:29] <tassadar_> well, damn) which nexus do you have, 32gb with 3g?
[18:29] <cortexA9> no
[18:30] <cortexA9> 32 wifi
[18:30] <gurgalof> i have 32 with wifi too
[18:30] <gurgalof> it wont boot ubuntu sending over with -S 600M
[18:31] <tassadar_> cortexA9: I dunno, honestly, ton of things could be wrong - it is just not made to dual boot 13.04
[18:32] <cortexA9> mmm
[18:32] <kulve> I think it writes all those 600M pieces in the start of the partition..
[18:32] <tassadar_> well, just formating the /data partition in recovery and copying the roofs.tar.gz in there should work okay
[18:32] <cortexA9> tassadar_: ok no problem
[18:33] <gurgalof> i did make_ext4fs -s -l 27G rootfs.img build/
[18:33] <gurgalof> how should i send i over when fastboot wont do it
[18:34] <kulve> I've used a modified initrd script that passed the parition as usb mass storage to the PC. Then I can do whatever I want with it
[18:34] <tassadar_> what is in the build/ folder? there should be just one tar.gz in there, right?
[18:35] <gurgalof> yep
[18:35] <tassadar_> do you have some custom recovery installed on n7?
[18:35] <kulve> is the image <700M?
[18:35] <gurgalof> no and no
[18:35] <kulve> can't flash it then with fastboot
[18:36] <gurgalof> ending 'userdata' (728117 KB)...
[18:36] <gurgalof> a little too big
[18:36] <kulve> the limit is about 700M, I'm not exactly sure about the size
[18:37] <gurgalof> what does that limit come from?
[18:37] <kulve> it goes to memory first
[18:37] <gurgalof> ah
[18:37] <tassadar_> if you had the recovery installed, you could copy the tar.gz into /data partition, without flashing
[18:37] <tassadar_> either via adb push or via OTG flash drive
[18:37] <cortexA9> you can add rom
[18:38] <cortexA9> rootfs right
[18:38] <tassadar_> ?
[18:38] <cortexA9> no nothing sorry
[18:38] <cortexA9> :)
[18:39] <cortexA9> tassadar_: and with apt-get dist-upgrade ?
[18:39] <cortexA9> i can upgrade at 13.04 ?
[18:39] <cortexA9> from 12.10
[18:40] <tassadar_> it will probably just break - v2 does some ugly things to make dual-booting work :/
[18:40] <cortexA9> mmm
[18:40] <cortexA9> maybe not :P
[18:41] <cortexA9> i try :D
[18:41] <kulve> http://ruedigergad.com/2012/12/09/nexus-7-easily-flashaccess-entire-userdata-partition/
[18:41] <kulve> that's what I used for my non-ubuntu rootfs
[18:42] <cortexA9> it's a question of packages..
[18:42] <cortexA9> i think
[18:42] <gurgalof> i need a 27GB image, that is under 700MB...
[18:43] <cortexA9> why you need that ?
[18:43] <kulve> that's not a problem if you have only a 500M of files in there :)
[18:43] <gurgalof> i have the same files as the daily build
[18:43] <gurgalof> the 6GB image is 40MB smaller
[18:44] <gurgalof> and it will flash
[18:44] <cortexA9> how can i put kubuntu ?
[18:45] <cortexA9> just install kubuntu-desktop ?
[18:45] <cortexA9> but i tried..
[18:45] <cortexA9> but still open unity..
[18:46] <cortexA9> strange
[18:46] <gurgalof> hmm maybe a higher compression on the tar.gz may work
[18:47] <tassadar_> can you remove some packages from the build?
[18:47] <cortexA9> who?
[18:47] <tassadar_> gurgalof
[18:48] <gurgalof> dunno, just wanted the daily build, but the right size for 32GB
[18:48] <kulve> gurgalof: create the image without the rootfs.tar.gz and flash that. Then follow the instructions in the blog post, mount the partition like an USB stick and copy as big rootfs.tar.gz there as you want
[18:49] <kulve> the fastboot command there with the moslo images doesn't flash anything, just temporarily boot with those files.
[18:49] <cortexA9> tassadar_: one question
[18:49] <gurgalof> i see, i will try in a moment....
[18:50] <tassadar_> yes
[18:50] <cortexA9> the modified recovery add multirom right ?
[18:51] <cortexA9> i flashed it with nexus 7 toolkit
[18:51] <cortexA9> the button multirom right
[18:51] <cortexA9> because they didn't appear
[18:51] <cortexA9> because it didn't appear
[18:52] <cortexA9> with only multirom
[18:52] <tassadar_> do you use some theme for TWRP?
[18:52] <cortexA9> no..
[18:52] <gurgalof> what, an empty image takes 140MB....
[18:53] <tassadar_> cortexA9: i don't really understand what you need)
[18:54] <tassadar_> you have to flash modified recovery image - I don't know what does the toolkit does, does it flash recovery by itself or does it let you choose the .img file?
[18:54] <cortexA9> tassadar_: because with only multirom it didn't appear in TWRP..
[18:54] <cortexA9> just this
[18:54] <cortexA9> yes i can choose the img file
[18:54] <tassadar_> you have to flash bot recovery and multirom zip
[18:54] <tassadar_> *both
[18:54] <cortexA9> ok
[18:55] <cortexA9> must go
[18:55] <cortexA9> eat
[18:55] <cortexA9> bye
[18:58] <gurgalof> kulve, to compile moslo i need kernel zImage...
[18:59] <kulve> isn't the needed kernel and initrd images in that moslo package that you can extract with rpm? The instructions are there on the post, a bit inconvenient though..
[19:00] <gurgalof> can i use rpm in ubuntu, isn that fedora shit
[19:03] <gurgalof> kulve, ?
[19:13] <gurgalof> seem that ican use alien to conver rpm to deb
=== carif_ is now known as carif
[19:30] <gurgalof> kulve, how do i send the tar.gz over via telnet?
[19:31] <cortexA9> you know ssh doesnt work in arm ?
[19:32] <gurgalof> nvm, saw that i got a mass storage device
[19:34] <cortexA9> i think there is a problem with openssh in arm
[19:34] <cortexA9> in quantal
[19:34] <cortexA9> i tried it
[19:42] <infinity> cortexA9: Eh?  SSH works on ARM just fine.
[19:43] <cortexA9> sure ?
[19:43] <cortexA9> mmm
[19:44] <cortexA9> i lost the connection
[19:44] <cortexA9> after login
[19:44] <infinity> Positive.  I use it all the time, on many different ARM hosts.
[19:44] <LisaNori1> I've certainly used ssh a number of times on my nexus7 running raring.
[19:44] <infinity> If it lets you login, THEN you lose the connection, that's not SSH having an issue, that's something logging you out or killing your shell.
[19:45] <cortexA9> i mean in quantal..
[19:45] <infinity> Yes, I heard you.
[19:45] <infinity> SSH on ARM in quantal works fine.
[19:45] <cortexA9> no for LisaNori1
[19:46] <LisaNori1> Yep, I know.  I was just adding another data point.
[19:46] <cortexA9> ok
[19:46] <cortexA9> i don't know what is..
[19:47] <cortexA9> very strange
[19:57] <tassadar_> ssh in 12.10 on n7 works okay for me
[20:01] <kulve> gurgalof: so you did get it mounted over usb?
[20:02] <kulve> and about the rpm, you can "use" it just fine in deb based systems, it just doesn't have any packages in the DB, so installing anything is a bit tricky. But for extracting packages or checking the info of them works nicely
[20:08] <tassadar_> hmm, I do wonder if n7's bootloader can boot the second bootloader, like u-boot
[20:09] <tassadar_> I mean, there is a entity called "second" in the boot.img, looks like it is just for that purpose
[20:10] <RaYmAn> I have yet to actually see any devices support the second part in boot.img's
[20:11] <RaYmAn> but you could technically chainload a non-initializing u-boot packed as a boot.img kernel
[20:13] <tassadar_> ooh, so that is the way grub could actually be done even for devices with "locked" bootloader
[20:14] <tassadar_> now I see what ogra_ meant
[20:20] <gurgalof> kulve, yep, got it working...
[20:20] <kulve> gurgalof: great

[23:35] <quince> Hi.  Just booted with daily build on nexus 7 for the first time, great to see the logo on the screen :-)
[23:36] <quince> However, onscreen keyboard has stopped having any effect on the "Who are you" screen
[23:36] <quince> (ironic given that I was planning on doing some work on an onscreen keyboard)
[23:38] <quince> what's the best way to give it a poke?  I don't even know how to power it down from here...
[23:53] <quince> At some point I think the panel icons were unresponsive, and that trained me into thinking that the "Who are you" dialog was modal.  In fact I could just reboot using the power button icon at the top (but not using fastboot -- why?)
[23:54] <quince> got through the dialog fine this time...
