saucy Xorg Segmentation fault

[gregrwm]

saucy Xorg can launch and display an xterm, but segfaults when twm is launched, or mouse is moved, or under lightdm. same hardware works fine under precise. Additional attachment contains:

Status changed to 'Confirmed' because the bug affects multiple users.

[booble (yashin-vladimir)]

For me lightdm over Xorg starts fine and works until I try to login to kde.
Then I see kde applications starting, I can even see my desktop for 2 seconds and then xorg crashes.

Nvidia binary driver 319.60-0ubuntu1 is installed
Ubuntu 13.10, problem appeared after upgrade.
% uname -a
Linux 3.10.4-031004-generic #201307282043 SMP Mon Jul 29 00:44:07 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

On 13.04 same configuration worked fine.

I use integrated video on laptop to drive laptop's LVDS and discrete Nvidia card for 2 external monitors: DVI and DisplayPort.
Xinerama is used across all monitors.

If I try to use Nvidia card with one DVI monitor then no crashes are observed.

Please let me know what other information might be useful, I will try to collect it ASAP.

Thank you.

gregrwm, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xorg REPLACE-WITH-BUG-NUMBER

Thank you for your understanding.

Hi Chris,

Actually the problem was solved for me once I installed nvidia driver from xorg-edgers PPA.
Here is my current driver version: 331.20-0ubuntu8~xedgers~saucy1

Looks like the driver in Ubuntu repository is too outdated and has some issue with new xorg and/or some configurations.

Thanks!

[gregrwm (gregrwm)]

yes, still the same, running latest current liveCD.

tried: apport-collect -p xorg 1238880
got:
ERROR: connecting to Launchpad failed: [Errno 8] _....

tried ping of 8.8.8.8, worked, tried changing resolv.conf to 8.8.8.8, still got same error.

(was still copying down error message when presumably lightdm yet again tried to launch xorg, i of course yet again tried to switch the virtual terminal back to see the rest of the error message, and instead got a garbled and unresponsive screen, a different latent bug no doubt in some driver that has shown up when switching VTs in rapid succession, have seen *this* bug since many releases ago.)

[penalvch (penalvch)]

gregrwm, thank you for performing the requested test. Could you please execute the following in your current install so that it would attach additional debugging logs:
apport-collect -p xorg 1238880

did the apport-collect for you from both precise (which works fine) and saucy (which segfaults), yes i launched it multiple times while working out how to appease it. it appeared to me i succeeded once each for precise and saucy, so i'm surprised to see 3 entries above..

[gregrwm (gregrwm)]

[gregrwm (gregrwm)]

ok i installed trusty, launched X, 2 xterms, and twm, so far so good, then i launched lxrandr, then xorg segfaulted. then i ran:
apport-collect -p xorg 1238880
did that get you what you need?

[penalvch (penalvch)]

gregrwm, thank you for your comment. Unfortunately, it did not provide the expected information. Could you please ensure xdiagnose is installed, and if so, after doing the apport-collect a window pops up which you would need to say yes to for the debug logs to be attached:
"Your display manager log files may help developers diagnose the bug, but may contain sensitive information such as your hostname. Do you want to include these logs in your bug report?" -> Yes

Could you please advise?

ok installed xdiagnose, reran apport. note the sequence:

..==== AUTHENTICATING FOR com.ubuntu.apport.root-info ===
Authentication is required to collect system information for this problem report
Authenticating as: ,,, (mino)
Password: ..............................................................................................................................
.==== AUTHENTICATION COMPLETE ===

no windows are popping up (xorg isn't running). it was still typing periods twice per second or so, so it wasn't very clear, but i guessed it wanted a sudo password. seemed to work. got what you wanted yet?

[penalvch (penalvch)]

gregrwm, thank you for performing the requested information. Could you please provide the full computer model as noted on the sticker (ex. Compaq Deskpro EN Desktop PC 6450+)?

[gregrwm (gregrwm)]

"COMPAQ DESKPRO"
"intel inside pentium II"
"DPEND-P350/6 4/N4 US"
"COMPAQ SERIAL NUMBER NO. 6848 BW32 D190"

[penalvch (penalvch)]

gregrwm, thank you for providing the requested information. The next step is to fully commit bisect from Precise to Saucy, in order to identify the offending commit. Could you please do this following https://wiki.ubuntu.com/X/Bisecting ?

[gregrwm (gregrwm)]

ok i got this far:
  $ git clone git://anongit.freedesktop.org/git/xorg/driver/xf86-video-mach64
now what is the Ubuntu Way to compile and test it?
