xf86-video-radeonhd-1.2.3 crashes Xorg when DPMS powers off the screen. See URL. This was fixed long ago in upstream git repo.
Created attachment 174109 [details, diff] Fixes the crash Taken from upstream git commit 9ca2384d14612eab710450e5a527dcc345e4179c. From: Egbert Eich <eich@freedesktop.org> Date: Fri, 31 Oct 2008 17:31:41 +0100 Subject: BIOSScratch: Treat DAC SENSED_NONE as CRTC output. The BIOS scratch bit that gets set when no DAC load has been detected is will default to CRTC to avoid having the condition that no output type is set.
Thanks for submitting this fix! Assigning to maintainers.
Unfortunately the patch does not fix the problem completely: I am still seeing crashes when the screen is turned off to save power. The bug is fixed in git master branch however, so I suggest to put a snapshot from git in portage. It's working fine here.
1.2.4 has been released.
I think you should change Severity from "critical" to "enhancement". Anyway, me too would like to see radeonhd 1.2.4 in the tree.
in CVS, thanks!
