Description:

The latest xf86-video-intel package in [testing] segfaults when the displays go into DPMS standby on my system. This package enables SNA for acceleration. Switching the AccelMethod back to uxa using the method given in the install message fixes the issue for me.

Additional info:
Package version: xf86-video-intel 2.21.15-2

Please check for known upstream bugs and check if the recent beta release 2.99.907 also fails (recompile trunk with abs).

This is also reproducible in the 2.99.907 release. Switching to "uxa" acceleration works for me as well.

I did not find an open bug so I opened a new one with upstream: https://bugs.freedesktop.org/show_bug.cgi?id=73224

According to Chris Wilson from the bug report: xf86-video-intel-2.21.15 is incompatible with xorg-1.15

Is this an Arch packagaging issue then?

I'm going to bump to latest beta driver into our testing repo. If it keeps crashing keep reporting it to the fdo tracker.

I can't confirm this on my notebook. It doesn't seem to use DPMS properly since the initial setup.
The screen goes black but backlight keeps going. If you have an idea how to make it switch power off please tell me.

After updating to 2.99.907 I can no longer reproduce this problem. Just to be sure, I downgraded & upgraded 3 times and every time the old version would crash, new version didn't any more.

Although Adrian Băcîrcea said that he's able to reproduce this with 2.99.907, maybe he messed something up by accident?

I redid the test and the X server seg faulted again. I attached the Xorg.log and the xorg.conf at the time of the failure.
I test this by issuing the command "xset dpms force off".

   xorg.conf (0.2 KiB)

Adrian, please reopen the bug with upstream at and send your logs there: https://bugs.freedesktop.org/show_bug.cgi?id=73224

Also, get a gdb "bt full" stack trace, as requested by Chris.

It seems it was me after all. I upgraded to the package in testing and it's not reproducible anymore. Sorry for the false alarm.
