Two new data points: I tried on another computer with xorg-server 1.15.0 and glamor 0.5.1 and there it worked. I upgraded libdrm, xf86-video-ati and glamor to newest git (not the one included in the xorg-server). And then I got the same problem again. Also what type of rotation used matters, as I mentioned previously if I used the same rotation on both outputs it worked. But now I also note that if you can use left and right together and normal and inverted together. In other words: xrandr --output DVI-1 --auto --rotate left --output DVI-0 --rotate right --auto --primary xrandr --output DVI-1 --auto --rotate right --output DVI-0 --rotate left --auto --primary xrandr --output DVI-1 --auto --rotate normal --output DVI-0 --rotate inverted --auto --primary xrandr --output DVI-1 --auto --rotate inverted --output DVI-0 --rotate normal --auto --primary Also, tried with three monitors, then DVI-1 and HDMI-0 has to have the same rotation pairs (left/left, left/right, right/right, normal/normal, normal/inverted and inverted/inverted).

Think I have narrowed it down to xf86-video-ati, found a good commit and a bad one and bisected to: e4cd0f4392ea11c93088ad429f36eaaf9bcbf505 is the first bad commit commit e4cd0f4392ea11c93088ad429f36eaaf9bcbf505 Author: Alex Deucher <alexander.deucher@amd.com> Date: Wed Oct 30 15:21:26 2013 -0400 radeon: enable tiling on SI by default (v2) Now that mesa 9.2 is out with support for tiling on SI asics, we can enable it here.

I am going to try it on another box with a newer stack to see if setting ColorTiling2D to off helps there aswell. Using unmodified xf86-video-ati (git) with:
Section "Device"
Identifier "open"
Driver "radeon"
Option "ColorTiling2D" "Off"
EndSection
Makes it work.
I thought it was working quite nicely with Option "ColorTiling2D" "Off", but now I actually experienced the same problem again with it "Off". Also it is the exact opposite, it now only corrupts the screen if it is in normal rotation and not left. I am a bit puzzled to say the least, but maybe you can make more sense out of it? Updated to the latest git of the different versions, and now the behaviour is completly different, instead of stopping to update the other screen, the rotated screen is no longer lighting up. The behaviour seems random to me. Does this still happen with current xf86-video-ati Git master? This might fix it: http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=ce9914af8d8d5243977023ec7b09c605f9cca8b4 I have the same problem, rotate my 2nd screen in Ubuntu Wily and the screen corrupts. compiled the latest from xf86-video-ati but it doesn't fix the problem. installed the Vivid debs: xserver-xorg-video-ati_1%3a7.5.0-1ubuntu2_amd64.deb xserver-xorg-video-radeon_1%3a7.5.0-1ubuntu2_amd64.deb and they work.

Also recent kernels does not light up the display I usually test with (unrelated to this). Fortunately I have another computer I had the same issue with. And everything seems to work now. I have not tested to revert that patch to verify that it is really that commit that fixes it. Also only tested a couple of times, but I have experienced earlier that some options may mask it (or other random things). So I am going to test it more thoroughly tomorrow to make sure. tldr; It seems to work, will test more tomorrow. Could easily reproduced the problem when I tested with patch [1] reverted. With latest git I was unable to get the problem, so for me this problem is solved on the two computers I could test on. Thank you very much, this lets me enjoy my desktop alot more! :) [1] http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/patch/?id=ce9914af8d8d5243977023ec7b09c605f9cca8b4) |
