[00:08] <Tassadar> okay, my cmdline was missing these 3 parameters: "access=m2 quiet splash"
[00:08] <Tassadar> I added them, and onboard works like a charm
[00:08] <Tassadar> that is...unexpected Oo
[00:10] <Tassadar> something still crashes when I hide onboard and show it again, window's decorations disappear and input from onboard no longer gets into textfields
[01:51] <Jef91> sfeole you still around?
[01:59] <vanhoof> Jef91: the rootfs.img is derived from live build
[01:59] <vanhoof> tar/plain format
[01:59] <vanhoof> you can download it, mount it loopback and take a look
[01:59] <Jef91> vanhoof do you know what edits are made to the file system to allow it to be setup properly from the rootfs.tar.gz on the nexus 7?
[02:00] <vanhoof> http://www.mattfischer.com/blog/?p=285
[02:00] <vanhoof> its just a quantal or raring build w/ a seed trimming out the fat, nothing fancy
[02:01] <Jef91> So there is nothing extra added to the file system to allow it to boot on the nexus 7?
[02:02] <vanhoof> Jef91: checkout ubuntu-defaults-nexus7 package in the ppa
[02:02] <vanhoof> anything magic is handled there
[02:02] <vanhoof> but those are largely quantal specific, where the image was released at UDS
[02:02] <vanhoof> not for daily raring builds
[02:04] <vanhoof> Jef91: you've seen the build.sh script, yeah?
[02:04] <Jef91> yea looking at it now
=== zz_chihchun is now known as chihchun
[02:11] <Jef91> where the is ppa for that pacakge again vanhoof?
[02:12] <Jef91> nvm found it

[03:32] <Jef91> hrm my custom nexus rootfs is giving me:
[03:32] <Jef91> "mount: mounting /dev on /root/dev failed: No such file or directory" and "target filesystem doesn't have requested /sbin/init" and then it dumps me to a busy box. Any suggestions as to what I might be missing?
[03:34] <mjrosenb> Jef91: you should not be mounting /dev anywhere
[03:35] <mjrosenb> /dev/sdfoo or /dev/mmcblkbar sure
[03:35] <Jef91> hrm
[03:37] <Jef91> if I try to install the 8gb image on a 16gb nexus 7 will it have issues?
[03:38] <infinity> mjrosenb: I assume that's an initrd moving the mount from /dev in the initrd to /root/dev before pivoting root.
[03:38] <infinity> Jef91: ^
[03:39] <infinity> Jef91: And the last message is also from an initrd telling you it can't find /sbin/init on /root
[03:39] <Jef91> my filesystem has a /sbin/init file
[03:39] <infinity> Jef91: So, your rootfs isn't being mounted, or it's being mounted but is empty and/or corrupt.
[03:39] <Jef91> or is it referencing something else?
[03:39] <infinity> From the POV of the initrd, your filesystem really doesn't have init.
[03:39] <infinity> Why that is, I can't say.
[03:39] <Jef91> Alrighty.
[03:40] <infinity> (It also doesn't have /dev)
[03:40] <infinity> In other words, it's probably just not seeing it right.
[03:40] <Jef91> My file system is Debian Wheezy ARMHF
[03:40] <Jef91> But I've recompiled the Ubuntu nexus 7 packages, thinking they would work with it
[03:40] <Jef91> but that might not be enough
[03:41] <Jef91> namely I've installed the "tarball-installer" package along with "ubuntu-defaults-nexus7" any idea if I need something more than those two to make the rootfs install via fastboot?
[03:42] <infinity> Oh.
[03:42] <infinity> Did you also generate an initrd after installing tarball-installer?
[03:43] <infinity> That initrd is the one you should be booting with.
[03:44] <Jef91> ha whoops
[03:44] <Jef91> I did not
[03:44] <Jef91> How abouts would I go about doing that infinity?
[03:44] <Jef91> I just copied over the /boot from the Ubuntu FS
[03:45] <Jef91> I moved over /boot, /lib/firmware and /lib/modules
[03:45] <infinity> update-initramfs -u in your new rootfs.
[03:45] <Jef91> (that is what I have done for a number of other ARM devices, wasn't sure if this was different)
[03:45] <Jef91> Will there be any conflicts if I had copied over those directories from Ubuntu?
[03:46] <infinity> Erm.  This is a bit more involved than just copying files around, if you're wanting it to *install* the same way our images do.
[03:46] <infinity> See live-build/auto/build from the livecd-rootfs source.
[03:46] <infinity> Search for nexus7
[03:47] <infinity> We create the boot.img with abootimg, and then create the rootfs, which is an ext4 sparse filesystem with a tarball inside it.
[03:47] <infinity> Then you flash both those bits, and the boot.img runs the tarball installer.
[03:47] <Jef91> Ahh I didn't create my own boot.img
[03:47] <infinity> If that's not what you actually wanted, then you didn't want tarball-installer.
[03:47] <Jef91> I'd just been using one of the ones from Ubuntu
[03:48] <Jef91> I'll generate my own
[03:48]  * Jef91 will stop trying to shortcut
[03:51] <vanhoof> Jef91: what variant (8, 16, 32, 32+3g)?
[03:52] <Jef91> 16 vanhoof
[03:52] <Jef91> So I need to generate a fresh boot.img even with the same kernel Ubuntu uses?
[03:52] <vanhoof> ah ok, you should be good w/ p9 then for rootfs
[03:52] <vanhoof> 3g is p10
[03:52] <vanhoof> (partition wise)
[03:53] <vanhoof> well it needs to be flashed to the boot partition
[03:54] <vanhoof> since tarball-installer does its magic on first boot then vanishes
[03:54] <vanhoof> after that flash-kernel works as usual
[03:54] <SailorMoon> So whats the deal with Ubuntu for Nexus 7?
[03:55] <SailorMoon> Is it being developed for fun or should we expect something serious of it?
[03:55] <vanhoof> its quite active
[03:55] <vanhoof> http://status.ubuntu.com/ubuntu-raring/group/topic-raring-desktop-targets-for-embedded.html
[03:55] <SailorMoon> from what ive seen, in its current state, its a bit unusable
[03:56] <vanhoof> SailorMoon: bits are still being migrated from the quantal -> raring daily
[03:56] <Jef91> aside from the fact that Unity is a memory hog it works pretty well SailorMoon
[03:56] <SailorMoon> i do hope it becomes usable someday, I have an OTG cable and a USB hub i use on my N7  for a mouse and keyboard, using that on Ubuntu would be Epic.
[03:57] <SailorMoon> I did see there were nightlies, and downloaded one, but i couldnt manage to figure out how to install it
[03:57] <vanhoof> SailorMoon: thats how I do most of my work (OTG)
[03:57] <SailorMoon> Was like a .gz with a .raw inside it
[03:57] <vanhoof> usb serial is new (and nice too)
[03:57] <vanhoof> connect and `screen /dev/ttyACM0 115200`
[03:57] <infinity> SailorMoon: The wiki has pretty clear instructions on what to do with the two downloaded files.
[03:58] <SailorMoon> The wiki doesnt say anything about the Nightlies
[03:58] <SailorMoon> It says how to install the .img files, wich i already knew.
[03:58] <infinity> Which nightlies are you refering to?
[03:58] <vanhoof> install https://launchpad.net/~ubuntu-nexus7/+archive/ubuntu-nexus7-installer
[03:58] <vanhoof> and if you choose to re-download, it'll pull the new daily
[03:59] <infinity> https://wiki.ubuntu.com/Nexus7/Installation#Manually_Installing_Ubuntu_13.04_on_Nexus_7 <-- How to install dailies.
[03:59] <SailorMoon> infinity: this one http://cdimage.ubuntu.com/daily-preinstalled/current/
[03:59] <infinity> SailorMoon: Yeah, the above tells you exactly what to do with those two files.
[03:59] <SailorMoon> yeah step 2 says "gunzip", wtf is a gunzip
[03:59] <infinity> SailorMoon: "gunzip foo.img.gz"
[03:59] <vanhoof> SailorMoon: install the package from the ppa
[03:59] <vanhoof> it does it for you
[03:59] <SailorMoon> I'm running Windows on my Desktop lol
[03:59] <vanhoof> oh
[04:00] <infinity> Do you have a fastboot binary for Windows?
[04:00] <SailorMoon> Tried using 7z but it just showd a .raw inside
[04:00] <SailorMoon> Yep
[04:00] <infinity> If so, these instructions will work just fine, but yes, you'll need something to unzip.
[04:00] <infinity> Like good ol' winzip.
[04:00] <SailorMoon> i used 7zip but again, file.raw inside
[04:00] <SailorMoon> Also tried Winrar
[04:01] <infinity> Oh, if they're renaming it to file.raw instead of file.img, that doesn't really matter.
[04:01] <Jef91> SailorMoon: the install instructions are pretty clear you need Ubuntu on your desktop in it's current state :P
[04:01] <infinity> Jef91: Not really true.  With a sane fastboot, it should work from Win32 too.
[04:01] <SailorMoon> so i should just assume .raw is the name of the image?
[04:02] <SailorMoon> Jef91: ive said like 10 times, i've installed the normal .img files fine
[04:02] <SailorMoon> these compressed files dont contain .img files
[04:02] <SailorMoon> and confused me
[04:02] <infinity> SailorMoon: Well, it is, in fact, image.raw at one point in the build process.  We likely rename it.
[04:02] <SailorMoon> Good to know
[04:02] <SailorMoon> i didnt know that before, confused me TT lol
[04:02] <infinity> So, your unzippy thing is just being a bit too smart, I suspect.
[04:03] <vanhoof> infinity: rename to .img?
[04:03]  * vanhoof has no clue on win
[04:03] <infinity> That said, you could get gzip/gunzip for Win32 from here: http://gnuwin32.sourceforge.net/packages/gzip.htm
[04:04] <infinity> vanhoof: The name of the image is completely meaningless, it's just a raw blob of blobbiness anyway, fastboot doesn't care.
[04:04] <infinity> That said, gunzip will definitely give you The Right Thing, I have no idea what WinRAR for 7zip will do (though, they should be doing similarly Right Things)
[04:04] <infinity> s/for/or/
[04:04] <vanhoof> cygwin? :)
[04:05] <infinity> This gzip is native, no need for cyg.
[04:05] <vanhoof> infinity: right, just never used fastboot on win myself
[04:05] <infinity> vanhoof: Fastboot on Win32 is far better tested than on Linux, so it better work. :P
[04:05] <vanhoof> infinity: heh
[04:05] <infinity> (Sadly, we're not actually the dominant OS in the world... Crazy talk, I know)
[04:05] <vanhoof> infinity: say it aint so!
[04:06] <infinity> It saddens me too.
[04:06] <SailorMoon> what is dup?
[04:06] <SailorMoon> Its completely unrelated but you guys r smart n stuff
[04:06] <infinity> vanhoof: Anyhow, we could totally whip up a quick-n-dirty installer (probably not a GUI, unless you want to do actual work, but we could script something and bundle it with gzip, etc) for Win32..
[04:07] <vanhoof> infinity: totally out of my element there, perhaps a holiday venture, if i use windows, cygwin is the first thing installed ;)
[04:07] <infinity> vanhoof: Yeah, native is much saner in this case.  Though, I tend to agree, Windows without a sane POSIX environment drives me batty.
[04:08] <vanhoof> infinity: s!!! ;)
[04:08] <infinity> Heck, it's the only thing that makes MacOS usable.  I spent about 10 minutes trying to "intuitively" deduce how to help a friend with an OSX problem the other day before I just broke down, hit a terminal, and beat it with a hammer from the back end.
[04:08] <infinity> Intuitive GUI, my ass.
[04:09] <vanhoof> same w/ OSX, fink!
[04:09] <vanhoof> lol
[04:09]  * vanhoof envisions being punched by infinity at some point
[04:10] <infinity> If I used OSX at all, I'd likely use fink.  But, why would I use OSX?
[04:10] <infinity> That sort of implies wanting the GUI which, as stated above, is completely unusable to me.
[04:10] <vanhoof> heh
[04:10] <infinity> It also implies wanting the hardware, and I'm allergic to mice with fewer than three buttons.
[04:11] <infinity> If Lenovo ever drops the middle button, I might just find a new career, computers will be dead to me.
[04:11] <vanhoof> infinity: im dreading moving away from my x220
[04:12]  * vanhoof is not a fan of the new keyboards
[04:12] <infinity> Oh, really?  I think they've actually done a stellar job on their chicklet keboards.
[04:12] <vanhoof> you like em?
[04:12] <infinity> They're about 20x more usable than the Apple/Samsung keyboards.
[04:12] <infinity> I actually really like the feel.
[04:12] <infinity> And they certainly gunk up a lot less than the old skool Thinkpad keyboards.
[04:12] <vanhoof> i just love my old reliable lenovo keyboard
[04:12] <infinity> I used to have to replace mine every year or so.
[04:13] <vanhoof> thought I am not a user of the lenovo nipple :)
[04:13] <vanhoof> people think im crazy
[04:13] <infinity> I dunno.  It's not AS NICE a touch as the classic ThinkPad keyboards, I won't pretend it is, but they've done a really good job.
[04:13] <infinity> They're still very IBM/Lenovo ThinkPadish.
[04:13] <infinity> Only took me a week or so to get my typing speed back into the 120+ WPM range after switching from old to new ThinkPads.
[04:14] <infinity> Now I bounce between the two, and they both work well.
[04:14] <vanhoof> infinity: I think i'll skip the x230
[04:14] <vanhoof> see what haswell and lenovo have in next year
[04:14] <infinity> Well, I doubt they'll bring back the old keyboards.
[04:14] <vanhoof> yeah
[04:14] <infinity> Does Toshiba still ship them?
[04:15] <infinity> They were the only other vendor with this style of keyboard in recent years.
[04:15] <vanhoof> not sure, havent spent much time w/ toshiba
[04:15] <infinity> (Shame their laptops were otherwise hideous)
[04:16] <vanhoof> i dunno, big thing with me and thinkpads is accessability
[04:16] <infinity> So, do you know any fans of the old skool keyboards who'd want to buy a near-mint T420s? :P
[04:16] <vanhoof> yeah i want a new hdd, easy ... pop in mstata in pcie, easy
[04:16] <infinity> Toshiba was modular long before IBM was.
[04:16] <vanhoof> i hate having to rip apart a laptop to add in new parts
[04:17] <infinity> Though, it was more than 15y ago that I was doing laptop service.
[04:17] <infinity> I'm sure things changed.
[04:17] <infinity> A bit.
[04:17] <infinity> Either way, a quick poke at their website shows they've also gone chicklet.
[04:18] <vanhoof> now i just need to sweet talk ogra_ into sending me a new panel for my ac100 :)
[04:18] <infinity> Oh, now that's a keyboard I find unusable.
[04:18] <infinity> The only one worse than the ac100 was the tf101.
[04:18]  * vanhoof misses his, shame the panel decided to die
[04:19] <vanhoof> yeah but for grab and go, its an awesome machine
[04:19] <infinity> The weight was hard to beat.
[04:19] <infinity> I eventually stopped using mine, though.
[04:19] <vanhoof> this x220 w/ a 9 cell battery is small but heavy :)
[04:19] <infinity> I keep tossing around the idea of replacing it with a Chromebook.
[04:19] <vanhoof> same here
[04:20] <infinity> Honestly, though, the 420s is actually stupid light and thin, for all the beef inside.
[04:20] <vanhoof> was looking at the install for it and it looks a mess
[04:20] <infinity> So I'm not sure I need more laptops.
[04:20] <infinity> Streamlining the Chromebook install and producing images for it was about the only argument I had for buying one.
[04:21] <infinity> Cause I think it would be a lovely all-in-one dev kit to recommend to people.
[04:21] <infinity> Sure beats saying "okay, go buy a Panda... And now buy a hard drive... And a monitor... And..."
[04:21] <vanhoof> heh
[04:22] <vanhoof> i think the install could be greatly condenced, everything i've found it way to manual
[04:22] <infinity> Oh, we could make it reasonably slick.
[04:22] <infinity> Except for the initial faff to get it into dev mode.
[04:23] <vanhoof> well same w/ n7
[04:23]  * infinity nods.
[04:24] <infinity> Meh.  Would have made a good holiday project, but there's no way I can get an American to ship me one before January now.
[04:24] <vanhoof> infinity: i work for beer
[04:25] <vanhoof> ;)
[04:25] <infinity> vanhoof: I meant there's just no way (short of FedEx overnight, twice) that it would get here in time for me to do anything with it over the holidays.
[04:25] <infinity> vanhoof: And overnighting it from a retailer to you, and then from you to me, would make it a fair chunk more expensive than the sticker price. :P
[04:26] <infinity> Sort of defeats the purpose of buying cheap hardware.
[04:26] <vanhoof> infinity: yeah but then you owe me archive work ;)
[04:26] <vanhoof> win/win
[04:26] <vanhoof> lulz
[04:26] <infinity> Oh, if you want to send me one for free, I'm okay with owing people favours...
[04:26] <vanhoof> looool
[04:27] <infinity> It's not like I haven't been working the last 5 days, despite being on "holidays".
[04:27] <infinity> Grr.
[04:27] <vanhoof> yeah seriously
[04:27] <infinity> May as well work on something I enjoy, instead of emergency SRUs for insane insanity.
[04:37] <SailorMoon> Installing COM24 ?
[04:37] <SailorMoon> COM26?
[04:38] <SailorMoon> COM32? D:
[04:38]  * SailorMoon panics
[04:39] <infinity> USB serial on Windows gets curious numbering.
[04:40] <infinity> FSVO "curious" that amounts to "completely nonsensical".

=== chihchun is now known as zz_chihchun
[04:41] <SailorMoon> This nightly/daily is booting different =o
[04:41] <SailorMoon> Is using Gnome/unity really a good idea on a device like the Nexus 7?
[04:42] <infinity> It's more a proof of concept at this point than a finished product.
[04:42] <infinity> And a good baseline for people to go hunting memory/power/etc issues.
[04:43] <SailorMoon> So you dont think we'll be using Gnome later on? :3
[04:44] <Jef91> So I got my file system loaded up with the installer scripts
[04:44] <Jef91> It is getting kernel panic referencing various libnih .so files it is missing
[04:44] <Jef91> but I am making progress
[04:51] <infinity> SailorMoon: I can't say (because I honestly don't know -- ignorance is bliss) what direction the mobile/slate efforts will go in, but any work put into gnome/compiz/unity certainly won't be wasted effort.
[04:51] <infinity> SailorMoon: Even if it doesn't end up being used for slates, I won't mind my laptop drawing 20% less power. :P
[04:57] <SailorMoon> We need a Dock for this :3
[04:58] <SailorMoon> Turn it into a netbook lolz
[04:58] <infinity> I need a way to both charge and have an external HDD, and I'll be happy.
[04:58] <SailorMoon> a dock with its own Power cable
[04:58] <SailorMoon> make it!
[05:00] <SailorMoon> The build im using doesnt allow for input, not from on screen keys or from usb keyboard.
[05:00] <SailorMoon> really weird.
[05:19] <Jef91> So - I've got my file system booted up on the 7 - but the touch screen is non-functional. Any idea what ubuntu package contains the drivers so I can rebuild them?
