I should note that currently I’m unable to bring up X entirely with the intel driver. Too bad I didn’t make a note of which upgrade this started with. With intel it now just freezes when login screen should appear, with just the cursor showing on a purple background. It’s such a tough lockup that REISUB from the keyboard won’t work, I have to power off to reset. Comparing logs might help determine if it’s the same issue on a grand scale or an unrelated one, but I don’t know how (or if) I can get useful logs from such lockups.
I downgraded libdrm-intel1 to 2.4.26-1ubuntu1 from Oneiric, but the problem remains. So on Precise it doesn’t seem to be the cause. (I’m not using the Xorg-edgers PPA.)
Here’s i915_error_state as requested on https://wiki.ubuntu.com/X/Troubleshooting/Freeze#. I made a copy (using cp), and I should mention that my first try to do so resulted in an error message: ”failed to extend” … and something about not having enough memory, in Finnish. When I preceded the command with LC_ALL=C to get the entire error message in English, the copying was suddenly successful. I hope this doesn’t mean the actual error state from the hang had been replaced by a new state which I’m now submitting.
Happens consistently when playing video using VLC (other players also), after about 5 minutes. Rockman 2 speedrun from tasvideos.org is pretty reliable for reproducing this. :)
The video goes blank (blue) and can no longer be seen until after reboot, though the playing does resume.
Bug #896899 looks similar on the surface, but I’ve little understanding of these types of crashes so I felt it best to report separately.
After switching to fbdev driver the crash can no longer be reproduced.
I can confirm the bug and the workaround both hold on an up-to-date Precise system with a Radeon HD 3200.
Thank you, I found this post useful so I flattr’d your Twitter account.
Mario, here’s output from the commands you asked.
Output of dkms status, ls /var/lib/dkms -R
I marked this as being Fixed for ”totem (Ubuntu)” because –no-existing-session has been removed from Totem altogether ( I’ve verified this in 12.04). So the bug as I initially described it no longer exists in recent *buntu.
Just a note that this no longer happens now that I’m running 12.04 with Unity; Unity’s run dialog expands tilde correctly. Still broken in Gnome panel 3.2.0 though.
Steps to reproduce:
1. Disable power saving
2. (Re-)boot (logoff may suffice, though I’ve not tested this)
3. Login and don’t touch mouse or keyboard after that
4. Wait
What happens:
Within half an hour (on my system at least) the display signal is turned off (monitor reports ”No signal”).
What you expect to happen:
The screen to stay on as indicated by power saving settings.
Additional info:
1. Any keyboard or mouse activity seems to make it obey the setting: after that the screen won’t go blank on its own (irregardless of whether or not the bug has manifested itself during the session).
2. I’ve disabled screensaver as well, though that probably doesn’t concern this bug.
3. From bug #854624’s comments I picked up this settings listing command, in case it helps:
jani@saegusa:~$ for c in `dconf list /org/gnome/settings-daemon/plugins/power/`; do echo -n ”/org/gnome/settings-daemon/plugins/power/${c}=”; dconf read /org/gnome/settings-daemon/plugins/power/${c}; done
/org/gnome/settings-daemon/plugins/power/sleep-display-ac=0
/org/gnome/settings-daemon/plugins/power/sleep-display-battery=0
