[12:57] <mpt> Hi, at Natty's login screen, whenever I move the mouse cursor even a single pixel, X apparently crashes then restarts. Is there anything I can do to make a bug report about that more useful?
[12:58] <jcristau> crashes how?
[12:59] <mpt> Actually, it looks identical to bug 747174, except I'm on a MacBook rather than a Dell

[12:59] <tjaalton> mpt: looking
[12:59] <mpt> As in, everything graphical disappears, there's a blinking text cursor in the corner of a black screen for a few seconds, then the login screen returns.
[13:00] <tjaalton> do you have nvidia as well?
[13:00] <tjaalton> ah
[13:00] <tjaalton> so it's the touchpad making it crash?
[13:00] <mpt> I guess so
[13:01] <mpt> I could try with an external mouse if that would help
[13:01] <tjaalton> can you verify it with an external mouse?
[13:01] <tjaalton> good :)
[13:02] <ricotz> tjaalton, i can confirm this here it too :(
[13:03] <tjaalton> https://lists.ubuntu.com/archives/natty-changes/2011-April/010439.html
[13:03] <tjaalton> maybe?
[13:03] <ricotz> it crashes in synaptics_drv.so
[13:03] <mpt> brb
[13:03] <tjaalton> try reverting to the previous version, if you have the package available
[13:03] <tjaalton> cnd: ^^
[13:04] <tjaalton> there's bug 747126 too

[13:05] <cnd> tjaalton, I'm looking now
[13:05] <tjaalton> cnd: great, thanks
[13:07] <mpt> ... Yep, it's the touchpad
[13:07] <tjaalton> mpt: ok, thanks for confirming, cnd is checking it out
[13:24] <cnd> mpt, would you be able to install xserver-xorg-input-synaptics-dbgsym and attach your /var/log/Xorg.0.log after a crash to bug 747126?

[13:25] <mpt> cnd, sure, but how would I install it?
[13:26] <mpt> Can I Ctrl + Alt + F1 from the login screen?
[13:26] <cnd> mpt, sudo apt-get install xserver-xorg-input-synaptics
[13:26] <cnd> ahh, yes
[13:26] <mpt> ok
[13:26] <cnd> but you won't have networking if you aren't logged in...
[13:26] <cnd> you can log in with the keyboard
[13:26] <mpt> I have Ethernet, is that enough?
[13:26] <cnd> then press 'ctrl+alt+t'
[13:26] <cnd> to get a terminal
[13:26] <cnd> mpt, no, it still won't connect to the network until you are logged in...
[13:27] <tjaalton> i think wired network should work?
[13:27] <cnd> tjaalton, network-manager likes to control *everything* :)
[13:27] <cnd> I have to manually set up my networking in /etc/network/interface for wired network to work when not logged in
[13:28] <tjaalton> heh, ok
[13:28] <mpt> Will I need to restart after installing it, or can I just re-crash X straight away?
[13:29] <cnd> mpt, you'll need to restart X
[13:29] <cnd> which you can do by a crash :)
[13:29] <cnd> then you need to crash once more
[13:29] <cnd> to get a real stack trace
[13:30] <mpt> ok
[13:30] <cnd> the trace should have function symbols, that's what we need
[13:31] <mpt> ok, trying that, bbiab
[13:32] <pgraner> mpt, seb128 tells me your seeing gdm dies when the mouse is used on todays updates?
[13:33] <cnd> pgraner, you seeing it too?
[13:33] <pgraner> cnd, yep everytime I can't login
[13:33] <cnd> mpt is getting me a stack trace with symbols so I can debug it
[13:33] <cnd> pgraner, you can blame me...
[13:34] <cnd> pgraner, you can downgrade to the previous version for a bit
[13:34] <cnd> and I'll be sure it's fixed soon
[13:34] <pgraner> cnd, thx man... I'll send my wife after you, its here machine 
[13:34] <cnd> ugh
[13:35] <pgraner> cnd, which pkgs need to be downgraded?
[13:35] <cnd> xserver-xorg-input-synaptics
[13:35] <cnd> I'll get a link
[13:36] <pgraner> cnd, thx
[13:36] <cnd> pgraner, https://launchpad.net/ubuntu/+source/xserver-xorg-input-synaptics/1.3.99+git20110116.0e27ce3a-0ubuntu8
[13:37] <cnd> ok, I think I may see the error
[13:42] <pgraner> cnd, downgrading it fixed it for now
[13:42] <cnd> pgraner, would you like to be a guinea pig for a fix?
[13:42] <cnd> I'm building a new package right now
[13:44] <pgraner> cnd, sure
[13:44] <pgraner> cnd, gimme a link when ready
[13:45] <cnd> pgraner, i386?
[13:49] <pgraner> cnd, yep
[13:49] <cnd> pgraner, http://people.canonical.com/~cndougla/utouch/xserver-xorg-input-synaptics_1.3.99+git20110116.0e27ce3a-0ubuntu10~test1_i386.deb
[13:49] <cnd> see if that fixes things
[13:49] <pgraner> cnd, ok on it now
[13:49] <cnd> mpt, I may have found the bug on code inspection
[13:50] <cnd> you can try out the package I pointed pgraner to if you'd like
[13:50] <cnd> the xserver log would still be helpful to confirm if you have it handy
[13:50] <mpt> cnd, I attached it to the bug report
[13:50] <cnd> mpt, thanks!
[13:50] <cnd> mpt, heh, wrong package installed
[13:51] <cnd> to get the bug symbols we need the -dbgsym package instead of the -dev package
[13:51] <mpt> cnd, there is no xserver-xorg-input-synaptics-dbgsym, so I guessed that -dev was the one you meant
[13:51] <cnd> ahh
[13:51] <cnd> I forgot, you have to enable the ddeb's repo
[13:51] <mpt> The who the what now?
[13:51] <cnd> heh
[13:51] <cnd> the dbgsym packages live in a separate repo
[13:52] <mpt> ok, so which should I try first, the .deb or the dbgsym?
[13:52] <jcristau> http://ddebs.ubuntu.com/pool/main/x/xserver-xorg-input-synaptics/?
[13:52] <pgraner> cnd, it works
[13:52] <cnd> so you have to add this to your /etc/apt/sources.list: deb http://ddebs.ubuntu.com natty main universe
[13:52] <cnd> pgraner, great!
[13:52] <cnd> thanks
[13:52] <pgraner> cnd, no thanks for the quick turnaround
[13:53] <cnd> tjaalton, I just pushed the fix to git
[13:53] <cnd> can you upload it for me?
[13:53] <tjaalton> cnd: yep
[13:53] <pgraner> cnd, amber is taking the screen shots for the Official Ubuntu Book today while she is traveling and she updated to the latest and .... a bit of panic here
[13:54] <mpt> cnd, does that mean no need for me to test anything?
[13:54] <cnd> mpt, correct, but you can install that fixed package for now to get things working again
[13:54] <mpt> ok, thank you
[13:56] <mpt> cnd, and will that .deb be overwritten by the new upload when it becomes available?
[13:56] <cnd> mpt, yes, it will
[13:56] <mpt> ok
[13:56] <cnd> there's no harm in installing it
[14:01] <tjaalton> cnd: uploaded
[14:02] <cnd> tjaalton, ta
[15:21] <Sarvatt> Amaranth: hrm ok looks like http://cgit.freedesktop.org/mesa/mesa/commit/?id=9a21bc640188e4078075b9f8e6701853a4f0bbe4 is what broke sandybridge in edgers between those 3/25 and 3/29 checkouts, of course its proving a PITA to revert right
[16:20] <bcurtiswx> the fix for the x crash, was it supposed to disable the two-finger scroll?
[16:29] <Sarvatt> good to know [ 4425.992922] [drm:i915_gem_do_execbuffer] *ERROR* Object ffff8801b0d60600 [handle 639, index 1] appears more than once in object list is a libdrm 2.4.23 problem, time to go through the intel bugs
[16:31] <Sarvatt> Amaranth: \o/ edgers works again on snb with http://bazaar.launchpad.net/~xorg-edgers/mesa/packaging/revision/84
[16:31] <Sarvatt> if only I could figure out the gles problem
[18:16] <seb128> did anybody mentioned usb mouse scrollwhell not working in natty?
[18:16] <seb128> it's not a new issue I get it for a while in natty, it's quite annoying
[18:17] <seb128> the click on it works but scroll up and down does nothing
[20:08] <Sarvatt> hrm scroll wheel works fine on 4 different usb mice here
[20:10] <bryceh> I've got two such mice which have been working fine (and get used a lot)
[20:11] <bryceh> hw maybe?
[20:14] <bryceh> Sarvatt, hey what do you think of us trying to get libdrm 2.4.24 in?
[20:15] <Sarvatt> i'd be ecstatic :)
[20:15] <bryceh> howso?  particular bugs it fixes or just fresh blood?

[20:18] <Sarvatt> i've hit that on sandybridge and had no clue what was causing it

[20:19] <Sarvatt> started going through bug reports looking for [drm:i915_gem_do_execbuffer] *ERROR* Object foo appears more than once in object list but got sidetracked with some dell stuff
[20:19] <bryceh> yeah might be this is the root of some of our other gpu lockups
[20:21] <bryceh> Sarvatt, ok if you want to shoot me the stuff you found I can take it from there
[20:23] <Sarvatt> I didn't find anything but only looked through about 10 bugs, got an OS reinstall going now that'll take about an hour so looking again now
[20:27] <Sarvatt> quite a lot of OOM crashes on intel lately eh?
[20:28] <bryceh> always has been
[20:28] <bryceh> constant battle...
[20:29] <bryceh> we've had bunches of IPEHR: 0x7xxxxxxx bugs, I wonder if they all boil down to this?
[20:30] <bryceh> probably about half the gpu bugs are false positives due to overeager apport hook
[20:30] <Sarvatt> 0x7xxxxxx was usually doing something with the 3D engine from what I remember, 0x18xxxxxx happening during modesetting
