Subject: /dev/dri/card0 sometimes vanishes when I exit Xorg (Radeon RS780)
Date: Sat, 29 Sep 2012 20:38:30 +0200 [thread overview]
Message-ID: <20120929183830.GA250@x4> (raw)
Hi,
since a few weeks the /dev/dri/card0 entry sometimes vanishes when I
exit Xorg. When I want to start Xorg again I get the following error
message:
...

Fatal server error:

I have to manually run "mdev -s" to restore the /dev/dri/card0 device.
This happens with an Radeon RS780 and Xorg version 1.13.0 running the
latest git kernel.
/sys/class/drm/card0/device/power_profile is set to "auto"
Is this a known problem? Are there any workarounds?
