[i915g] Karmic: intel i915 crash (locked up - had to power off)

[yossarian_uk]

Binary package hint: xorg

Hi.

After leaving my machine on over lunch (1hr) when I came back the machine had locked up, there was no display and I couldn't access a Console screen (ctrl+alt+F2, etc)

I had to power off / on .

I do have an opengl screen saver (which had in the past been fine)

syslog shows the following:-

00:02.0 VGA compatible controller [0300]: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller [8086:2582] (rev 04)
     Subsystem: Fujitsu Technology Solutions Device [1734:105b]

[Matt Taylor (dingus)]

Looks like this could be a duplicate of:
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/451518

[sebastien teyssier (steyssier)]

I can also confirm this bug on a similar machine with this intel video chipset :
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)

I neither have a screen saver nor desktop effects. This is a fresh and updated install.
while freezing, the mouse cursor still moves on the screen, but the keyboard is inactive (Caps Lock doesn't work)
It happens randomly, sometimes a few seconds after booting

I've also noticed this in xorg.0.log :

(II) LoadModule: "i810"
(WW) Warning, couldn't open module i810
(II) UnloadModule: "i810"
(EE) Failed to load module "i810" (module does not exist, 0)

[Stuart Overton (stuartoverton)]

A workaround that works for me is to do a SysReq R,E
That takes me to the console, a couple of Alt-right keypresses will get me to a console login.
I then log in and run "sudo service gdm start". Once I'm logged back into my desktop, I can run "sudo NetworkManager".
This at least removes the need for a full reboot.

[sebastien teyssier (steyssier)]

To confirm : it's been a few days that I've manually set "vesa" driver in xorg.conf and the system is working fine (and not so slow)

[pyronordicman (peter-eldridge-bailey)]

I am also affected by this bug. I have an Asus UL50vt laptop.

[Jérôme Poulin (jeromepoulin)]

I'm affected with a similar bug, only happened once, the GPU seemed wedged, so I took the dmesg log from SSH, I wasn't able to get a console with Sysrq, Xorg, compiz, i915 were all deadlocked.

[bugbot (bugbot)]

This bug report was filed against an old version of Ubuntu.
