Description Alex 2014-10-13 22:10:35 UTC
System environment:
-- chipset: 965GM
-- system architecture: 64-bit
-- xf86-video-intel: 2.99.911
-- xserver: 1.15.1
-- mesa: 10.2.2
-- libdrm: 2.4.54
-- kernel: 3.13.0-37-generic
-- Linux distribution: Xubuntu 14.04 LTS
-- Machine or mobo model: Lenovo Thinkpad R61 laptop


I am using Xubuntu 14.04 64-bits and Chrome as my main browser.  The computer is a Lenovo Thinkpad R61 laptop with an Intel 965GM video card inside.  Although everything was going fine when I was using Xubuntu 12.04, now, with 14.04, I am facing a problem that I am not able to find either a solution or a successful workaround for.

When I'm trying to watch a flash video, most of the time it works fine but randomly, the playback will pause right after it starts and 3-4 seconds later the screen will go black.  By saying black, I mean it's switched off, not simply blank.  It doesn't go back on unless I restart the laptop.  Everything else keeps working fine when this happens, and I can even hear the sound of the video playing.  I can press Ctrl-W and close the Chrome window or Ctrl-Alt-F1 and go to TTY1 mode, logon and turn the system off normally using the poweroff command.

Sometimes, when I see the video pause like that and rush to close its window before the screen goes black, I can avoid it from happening.  If I attempt to play the same video again right after that, it plays fine and, most of the time, many more videos play just fine afterwards.  Till it happens again for some unknown reason so far and the story goes on...

The only app that causes this on a standard basis is glmark2 on a specific test it runs, which is called "[ideas] speed=duration:".  All previous tests are ok.  I don't know about the tests after this specific one of course.  I never get to test them.

Additionally, Chrome has caused this problem two more times and both are not flash video related.  It happened for the first time when I clicked on the "Download Chrome" link on the google page at the point where it usually brings up a separate white window where the file links are and the second time when I clicked on a messenger contact in hotmail to see what happens now they brought msn back.  Never got to find out eventually.  :D

The point is that I've clicked the "Download Chrome" link tens of times after that and it always worked fine.  This issue is completely random.

It happens with both the Intel drivers installed with the system and the latest one I installed from Intel using 1.0.6 installer.  I also tried switching AccelMethod from SNA (the default) to UXA which seemed to save others from this issue but in my case it didn't.

As you understand, this is quite serious and it has become even more serious after the latest Chrome update to version 38 since it happens more often.

This is the beginning of the log entries concerning this, in syslog:

The file (/sys/class/drm/card0/error) it's referring to, is empty.  Nothing is actually saved in there.

I'd appreciate it if you could help on this one.  Thanks a lot everyone.  ;)

Just happened again when I simply tried to enter Chrome store.

Working is becoming impossible till this gets fixed.
Comment 2 Chris Wilson 2014-10-14 06:12:58 UTC
The file is not empty, ls is confused. Please attach /sys/class/drm/card0/error.
Comment 3 Alex 2014-10-14 12:36:47 UTC
It seems I had to open the "error" file as root only.
These are the contents: no error state collected

There is nothing else in that file.
Comment 4 Rodrigo Vivi 2014-10-15 20:51:51 UTC
Please reproduce the error, then immediatelly collect the i915_error_state file. Otherwise it will show "no error collected"

The requested "error" file

The "error" file.  The crash was produced by visiting google web store.

The Xorg.0.log file

The "dmesg" file.
Comment 8 Alex 2014-10-18 23:16:01 UTC
I have attached all three files.  All of them were created by the same crash that occured when I just visited google web store.  The web store always produces this crash.

I have disabled Hardware acceleration in Chrome for now and I can work.
Comment 9 Alex 2014-11-13 20:45:44 UTC
Are there any updates on this issue please?

I have installed the new updates two days ago but the issue remains the same.
Comment 10 lagreca 2014-11-14 17:12:39 UTC
My laptop is also affected by this bug, since its chipset is intel 965gm.

I'd like to hear good news about it.
