snadgehttps://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/121719611:16
snadgethis bug has been assigned to gnome-shell, but the original submitter claims the problem appeared with a kernel update11:17
snadgei just happen to be having the same problem, ie.. i seem to have a setup which can reproduce the above issue11:18
snadgewhat i want to try to do is downgrade to an older saucy kernel, to see if the problem goes away11:19
apwsnadge, sounds worth testing indeed11:20
snadgetheres no real reason that contrl-alt-t shouldn't open a terminal in metacity.. it does in unity.. i assumed it was a change in something relating to that11:20
snadgebut i've noticed that sometimes my keypresses arn't being registered.. particularly space11:21
snadgei just assumed my keyboard was becoming faulty / less responsive11:21
apwit seems highly unlikely that input handling is completely borked and noone has noticed, as kernel side that is completely orthoganal to the upper windowing system11:21
apwie it work be broke for everyone using any windowing at all, and the bug implies that downgrading from gnome-shell has fixed it for the reported no ?11:22
snadgeim using gnome in fallback mode with metacity.. im assuming the bug is related11:23
snadgeit started happening after an update a few weeks to a month ago11:23
apwsnadge, hard to say, but the test is easy to confirm if it is the kernel, boot an older kernel11:23
apwand if it goes away there is a relationship, it could still not be a bug in the kernel of course, but indicative11:23
snadgewhere can i find the older saucy kernels?11:27
apwsnadge, well you should first check if you have them in your /boot already as you can have more than one kernel installed at the same time anyhow11:29
snadgeyeah i've cleaned most of them out11:29
apwsnadge, otherwise they are in the launchpad librarian which has everything ever published: https://launchpad.net/ubuntu/+source/linux/+publishinghistory11:29
apwthat link has all the versions for the linunx package11:30
apwlook for lines for 'Saucy' 'release' 11:30
snadgethe version i want has been deleted11:32
apwit being 'deleted' just means it is not in the archive any more, because it was no longer referenced by a live archive pocket11:33
apwthe link on the rigth still has the launchpad librarian copies11:33
snadgeyeah im looking at that now.. udeb files and lots of module files.. what a headache11:33
snadgethis is new to me11:34
snadgei have to download all of them ?11:34
apwyou can ignore _all_ .udebs11:34
apwyou need just the common headers (an _all package) and the _<arch>.debs you need for your architecture and flavour11:34
snadgeok im going to try 3.9.0-711:40
snadgeok that one just freezes and wont input anything11:54
snadgehave to hard reset it11:54
=== fmasi is now known as fmasi_afk
snadgeok so if i dont install linux-image-extra.. my pc crashes ;)12:49
apwsnadge, heh that is half of the kernel after all13:52
snadgemetacity shortcut problem doesnt appear to be kernel related anyway13:56

kdubso, trying to compile saucy kernel for mako... complains that it can't find prebuilts/gcc/linux-x86/arm/arm-eabi-4.6/bin/arm-eabi-gcc-4.716:08
kdubso i probably have to install the toolchain there? do most people just symlink to a toolchain or something?16:08
ogra_rtg, ^^^ can you help kdub a bit ? they are trying to get kernel patches in for Mir 16:12
ogra_or apw 16:12
rtgkdub, I think I was cross-compiling that kernel in Raring. lemme check16:13
kdubyes, i'm at the point where i'm waiting on a fence from the sync driver forever, want to dig a bit into what is going on16:13
kdubthangs rtg 16:13
apwyeah i thought you needed the appropriate cross compiler in your chroot16:14
rtgyep, requires gcc-4.7-arm-linux-gnueabi in Raring16:15
apwi think we installed these two: gcc-4.7-arm-linux-gnueabihf g++-4.7-arm-linux-gnueabihf16:15
rtgkdub, ^16:15
apwor something didn't we ?16:15
rtgapw, right, gcc-4.7-arm-linux-gnueabihf16:16
rtgI think that gets everything you need16:16
kdubokay, giving it a try16:16
apwi think the one without hf gives you the el compilers, i _think_16:17
rtgkdub, echo "dpkg-buildpackage -d -B -aarmhf -us -uc"|schroot -c raring-amd6416:17
apwbut install the whole damn lot :)16:17
kamalapw, yes I'll apply the kteam-tools patch -- if I can get it past the whitespace police!  ;-)  thanks for the ack, man.16:17
* apw looks at kamal sideways ...16:17
kamalbut if you look at me sideways, then you'll see that my tabs and spaces don't line up!16:18
apwheh indeed16:18
rtgapw, impertinent pup today, isn't he ?16:18
apwalways, rtg, always16:18
apwkdub, or if you have a specific patch you want built we might be able to build it for you16:19
apwdepending on how desperate timewise you are16:19
* ogra_ guesses more desparate than we all can imagine16:19
kdubeh, i don't have a specific patch, just trying to get to the root of the problem still16:20
kdubthere's a moderately big delta between what qcom's current drivers put out and cm-10.1 kernel16:21
kdubso i'll probably have to come up with some patch (once I understand a bit more) that fixes things16:21
apwgood job we have so long before the release16:21
ogra_apw, touch works a lot different QA wise 16:22
ogra_we dont have freezes and milestones16:22
ogra_every daily image we release is handled like a milstone instead 16:23
rtgcking, have you got a bit to have a look at CONFIG_NO_HZ_FULL_ALL as well ?16:31
ckingrtg, yep, I can spin a kernel and test that tomorrow morning16:32
rtgcking, IIRC that was the config option that was giving us the most problems16:32
ckingrtg, yep, I think I recall that too16:33
kdublet me back up a bit... the way i'm used to building kernels for android is in the android source tree, the ubuntu touch kernels aren't built like that though, right?16:33
rtgkdub, nope, they are debian packaged16:34
kdubah :) i'll pursue that route then16:35
apwrtg, when you considering this nwe upload, for after thursday ?16:36
apwrtg, i want to switch out some hyperv bits for the next one16:37
rtgapw, dunno, anytime its convenient for you16:38
apwrtg, well we are fozded now through 'final beta' anyhow, so i'll get those patches sorted today 16:38
apwfrozded16:38
rtgapw, frozded -> frozen ?16:39
apwyeah, past-made-up-participle of freeze16:39
apwas on erm 9pm my time today, except it seems to have happened already16:39
apwas of16:39
rtgapw, k-freeze isn't until next week16:40
apwrtg, indeed, but we are in archive freeze now so anything you upload won't be getting out of -proposed till friday16:40
rtgapw, grumble. so much for development velocity.16:41
apwyeah we can upload, but we won't get any images, but i'll get my patches switched round next16:41
apwso i won't be holding u up16:41
apwrtg, ok those patches slammed in16:44
ppisatiit seems there's a new embedded linux distro for set top box&c:17:08
ppisatihttp://store.steampowered.com/livingroom/SteamOS/17:08
apwppisati, keep us informed as you find out more, i assume it will be linux under the hood after all the owrk they have done with us17:11
ppisatiapw: yes, it's linux17:11
ppisatiapw: "SteamOS combines the rock-solid architecture of Linux with a gaming experience built for the big screen."17:12
* ppisati wonders on top of which distro they built this thing17:12
apwppisati, yeah i wonder indeed17:16
* ogra_ bets its another ubuntu-core breed17:27
ogra_like the OS in the tesla and in the google cars 17:27
manjortg, yeah I am not in favor of disabling it wholesale 17:43
manjortg, but we need to turn off CONFIG_HVC_DCC coz that causes hangs as well ... 17:44
manjoppisati, ^ is cced on that discussion 17:44
rtgmanjo, lets run all those changes through ppisati17:44
manjoyep ack 17:44
manjohe is cced on all those conversations 17:44
ppisatimanjo: ???17:47
ppisatimanjo: email subj?17:47

manjoso 2 issues 17:48
manjoppisati, would you like to listen in on those calls ? I know you have better things to do ... so your call on that 17:49

kdubrtg, for building that arm kernel, what variant should debootstrap be? buildd isn't working for some reason18:56
=== fmasi_afk is now known as fmasi
apwkdub, you need to install the kernel build-depends in there obviously, but i assume you have done that19:02
manjortg, #hwe19:04

kdubapw, got the build started... had to do 'fakeroot debian/rules clean' first19:47
