[07:08] <dholbach> good morning
=== doko_ is now known as doko
[10:35] <probon1> hi all, i'm trying to make an image, but i keep getting errors that HAL is not configured
[10:35] <probon1> is there a known bug?
[10:35] <probon1> this is on hardy
[10:36] <probon1> using the moblin image creator, mccaslin-lpia platform, ubuntu-mobile target 
[10:45] <probon1> Setting up hal (0.5.10+git20080301-1ubuntu1) ...
[10:45] <probon1> polkit-auth: This operation requires the system message bus and ConsoleKit to be running
[12:24] <lool> probono: Curious
[12:24] <lool> probono: Could you please file a bug against MIC on launchpad?
[12:24] <lool> It should work
[12:36] <dns53> has anyone tried to install ubuntu-mobile hardy on an eeepc?
[12:57] <probono> lool: i need to experiment more
[12:57] <probono> lool: using the deb from moblin.org, i don't get this problem
[12:58] <lool> probono: What MIC are you using?
[12:58] <probono> is there any way to get full hardware support (as in the Ubuntu live CD) into a moblin image?
[12:58] <lool> Hmm I'd rather approach your goal the other way around: start from a live CD and add -mobile bits
[12:58] <probono> lool: at my 1st attempt, i used the one from hardy. now i'm using the one from moblin.org, on gutsy - this works (created a live usb image)
[12:59] <probono> now when i boot into that, my mouse doesn't work
[12:59] <lool> You're running the moblin MIC package on gutsy targetting hardy?
[12:59] <probono> yes, basically
[12:59] <probono> works w/o errors
[12:59] <lool> That's known not to work then; the problem is between the system dbus of gutsy and the hardy packages installed in the chroot
[12:59] <lool> probono: Run hardy on your host
[13:00] <probono> lool: now i'm getting confused
[13:00] <probono> using hardy as a host, using hardy's mic did *not* work
[13:00] <probono> using gutsy as a host, using moblin.org mic, *did* work
[13:00] <lool> probono: Were you creating hardy based images?
[13:01] <probono> i'm not sure about that, acutally
[13:01] <probono> as i said, i'm new to this
[13:01] <lool> probono: Make sure you wipe your ~/.image-creator and projects between your trials
[13:01] <lool> probono: That's fine, don't worry
[13:01] <probono> also, platforms ilke "mccaslin-lpia" are not exactly self-evident
[13:01] <lool> probono: Oh come on, it means mccalsin on lpia  ;)
[13:01] <probono> isn't there a platform "pc "?
[13:01] <probono> that equals the hardware that a ubuntu live cd assumes?
[13:02] <lool> probono: No, McCaslin is an Intel platform; just like Menlow
[13:02] <lool> probono: You can try running these kernels, but they might not work
[13:02] <probono> i have i945 machines, can't that work?
[13:02] <lool> If you want generic support, you should add generic kernels
[13:02] <probono> i915 also
[13:02] <dns53> what platform works with an eeepc, or should i install ubuntu and the meta package?
[13:02] <lool> Well we're not targetting anything else than mccaslin and menlow ATM
[13:02] <probono> dns53: welcome to the club :-)
[13:02] <lool> Not PCs, not EeePC
[13:03] <probono> dns53: i'm in the same boat
[13:03] <lool> But you're welcome to try running the software
[13:03] <probono> dns53: we should start a pc/eeepc target
[13:03] <probono> lool: yes. it does run, only it doesn't see my mouse (synaptics touchpad)
[13:03] <dns53> well what are the differences in cpu architecture? 
[13:03] <probono> which is why i was asking how i can enable full ubuntu standard live cd hardware support
[13:04] <lool> probono: Ubuntu Mobile is currently aimed at touchscreens
[13:04] <probono> lool: i understand that, but i'm lacking the hardware
[13:04] <lool> It's preconfigured for some hardware platforms such as the Q1 Ultra
[13:04] <probono> would like to get my development started w/o buying prerelease hardware
[13:04] <lool> probono: At this point, you're "on your own"  :-/  You will have to revisit things like the missing packages or change the Xorg config
[13:05] <lool> We're not trying to support all hardware in a generic fashion at the moment
[13:05] <lool> probono: You should be able to run apps in Xephyr though and installing standard Ubuntu packages will simply work
[13:05] <probono> lool: would it be hard? (i imagine it would basically involve a set of drivers packages)
[13:05] <lool> probono: If you're large on disk, simply install a regular Ubuntu and add the mobile packages
[13:05] <dns53> well the ubuntu-mobile works on gutsy when you add the missing package
[13:06] <probono> dns53: how would i do that? is there a wiki page on that?
[13:06] <probono> i'd also want my ubuntu to boot directly into mobile, not into gnome
[13:06]  * probono loves the usb-image-generator though
[13:07] <probono> come on, q1 is >1000 EUR
[13:07] <dns53> well just install ubuntu (eeexubuntu in my case) then install ubuntu-mobile, there was a package missing from the dependencies i can't remember what it was m something
[13:08] <probono> dns53: my actual goal would be to have a live cd/usb
[13:09] <dns53> sure, but you can atleast get something working the normal ubuntu way. i did test the image-creator but no targets worked
[13:09] <probono> mccaslin-lpia works, i can see the start screen, just have no mouse
[13:09] <probono> this is on a i945 machine
[13:12] <probono> dns53: after i installed ubuntu-mobile, how do i launch it?
[13:12] <probono> how do i replace gdm with it?
[13:14] <dns53> it should appear as a desktop entry in gdm, you may need to write your own script to launch it yourself and remove gdm
[13:15] <probono> ok, thanks
[13:15] <probono> dns53: does a stock ubuntu live cd work with the eeepc?
[13:16] <probono> uck (ubuntu customization kit) should allow one to remaster a live cd to include ubuntu-mobile, i guess
[13:17] <dns53> well you need to do some hacks to get everything working fine, X has a wrong resolution, madwifi needs to be customised. there are some scripts to add these things to a gutsy install

[15:20] <pat_mcgowan> rustyl_, how do you tell moblin-media to switch between using gstreamer and helix
[16:16] <rustyl_> pat_mcgowan, moblin-media will use the first media service it finds, and it finds the media service via the *.conf files in /usr/share/media-services/
[17:46] <pat_mcgowan> rustyl_, thanks for your earlier response
[18:42] <cwong1> Does anyone out there know anything about how /usr/share/applications/default.list is being created?
[18:51] <bfiller_> mjg59: trying to debug a problem on custom hardware with custom hotkeys. I'm using setkeycodes scancode keycode to map scancode to keycode. After doing so, still not getting keycode when using xev. Any ideas?
[18:51] <bfiller_> mjg59: I noticed you have worked on hotkey-setup package and thought that might help..
[18:51] <mjg59> bfiller_: What keycode are you setting it to?
[18:52] <bfiller_> mjg59: 97
[18:52] <mjg59> Hm. Ok, should be safe.
[18:52] <mjg59> Does evtest show it turning up?
[18:52] <bfiller_> mjg59: I haven't tried that
[18:52] <mjg59> That'd be a good thing to try
[18:52] <bfiller_> mjg59: will do, thanks. 
[18:53] <bfiller_> mjg59: also, what startup file should I put my "setkeycodes" command such that they are installed always?
[18:53] <mjg59> Best would be to add to hotkey-setup
[18:54] <bfiller_> mjg59: that can be used regardless of hardware?
[19:10] <lool> cwong1: dpkg -S tells me it's shipped by desktop-file-utils: /usr/share/applications/defaults.list
[19:11] <lool> cwong1: However, it's not checksummed; I'd guess it's updated subsequently when packages are installed; I would suppose update-desktop-database does so
[19:13] <lool> cwong1: Please don't call it directly in your postinst and postrm though, but leave it to dh_desktop to add the magic
=== asac_ is now known as asac
[19:42] <mjg59> bfiller_: Yeah, as long as there's dmi information from the platform
[19:42] <mjg59> bfiller_: If not, we'd need to work out something else :)
[20:30] <cwong1> lool: ping
[20:36] <lool> cwong1: pong
[20:36] <lool> cwong1: But do feel free to pack a question along with the ping to allow me to pong with the answer ;)
[20:37] <cwong1> lool: desktop-file-utils is not in the fset in MIC. Should it be?
[20:38] <lool> cwong1: I think we should use the fset concept as little as possible and instead rely on what the ubuntu-mobile package pulls for us; isn't it pulled by some other package?
[20:38] <cwong1> lool: Not that I know of
[20:39] <cwong1> lool: Also, the file default.list that get install when you do apt-get install  desktop-file-utils doesn't really fit our mobile enviroment
[20:43] <cwong1> lool: if desktop-file-utils is being pull in by an ubuntu-mobile package, would it be alright for one of our moblin package like home sreen to install it?
[20:43] <lool> cwong1: What's the problem with it?
[20:43] <cwong1> s/is/is not/
[20:44] <cwong1> lool: some of the mime type pointing to wrong app.
[20:44] <lool> cwong1: Are they pointing to one of the installed apps or an unavailable one?
[20:44] <cwong1> lool:  for example html is pointing to firefox instead of the midbrowser,   media file pointing to totem instead of moblin media player
[20:45] <lool> cwong1: Theoritically, this file should be updated after the installation of desktop-file-utils as its postinst calls update-desktop-database
[20:45] <lool> So the contents of the file should reflect the installed apps and what they declare supporting
[20:45] <lool> If you see mismatches, I'd first start by fixing the list of installed apps or the .desktop files which have been installed
[20:46] <lool> If that's not enough, we can look into overrides
[20:46] <cwong1> lool: so what you are saying is that all packages should do a db_update_desktop during the install, right?
[20:47] <cwong1> s/db_update/desktop/dh_desktop/
[20:47] <lool> cwong1: All packages should call dh_desktop during their *build* and this will make them call update-desktop-database after their installation and removal
[20:47] <lool> cwong1: Well, all "desktop" related packages which ship .desktop files naturally
[20:47] <lool> You don't need your kernel to call that obviously ;)
[20:48] <cwong1> lool: if the default.list file is not there, will updaet-desktop-database create one for you?
[20:48] <lool> cwong1: It should; look at /var/lib/dpkg/info/*.postinst
[20:48] <lool> Well don't look at that, grep it rather
[20:49] <cwong1> ok.  Thanks for the info.  I will look into it further.
[20:49] <lool> grep -l update-desktop-database /var/lib/dpkg/info/*.postinst
[20:49] <lool> cwong1: These are the snippets inserted by dh_desktop which will cause update-desktop-database -q to be run
[20:59] <cwong1> lool:  looks like if the file default.list is not there, update-desktop-database -q doesn't create one for you.  Any idea?
[21:01] <lool> cwong1: The file should be there as it's shipped by desktop-file-utils
[21:01] <lool> cwong1: dpkg -L desktop-file-utils | grep defaults
[21:03] <cwong1> lool: Yes if only you have install desktop-file-utils, but as I said before I don't think desktop-file-utils is part of the ubuntu-mobile image.  Correct me if I am wrong.
[21:04] <cwong1> cwong1: lool:  at least if it is not part of the image being created by moblin's image creator
[21:04] <cwong1> s/if//
[21:12] <lool> cwong1: Checking
[21:13] <cwong1> lool: k
[21:13] <lool> cwong1: That's probably correct indeed
[21:13] <lool> I only see ubuntu-desktop pulling it
[21:13] <lool> cwong1: As a stop gap measure, add it to your fset
[21:13] <lool> cwong1: The fix is in updating the ubuntu-mobile package
[21:14] <cwong1> lool: ok. so someone from your side will fix this, right?
[21:15] <lool> cwong1: Yes; you're welcome to file a bug
[21:16] <cwong1> lool: ok..  Thanks.
[21:16] <lool> against ubuntu-meta
[21:27] <lool> cwong1: Will be fixed by next ubuntu-meta upload (committed in our tree)
