Bug ID: 89815 Summary: DRI3 and EXA: scrambled output when switching monitors Product: DRI Version: XOrg git Hardware: x86-64 (AMD64) OS: Linux (All) Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: h.judt@gmx.at
I am using compiz-0.8. With DRI3 enabled in xorg.conf and AccelMethod EXA, the output becomes scrambled when switching monitors. This does not happen with DRI3 off and AccelMethod EXA, and does not happen with DRI3 on and AccelMethod glamour.
There seems no proper way to restore functionality except killing compiz (leaving a black screen) and starting another window manager, like xfwm4. After that, launching compiz again is not possible, I have to restart the X server.
Using xf86-video-ati git master (391900a670addec39515f924265bfa9f8bfa9ec0).

--- Comment #1 from Michel Dänzer michel@daenzer.net --- Please attach /var/log/Xorg.0.log and the output of dmesg, preferably from after the problem occurred.
What does "switching monitors" mean exactly?

There is nothing strange in dmesg.
The image looks scrambled and is frozen, yet slightly reminiscent of the original screen.

this: xrandr --output DVI-1 --auto --primary --output HDMI-0 --off xrandr -s 1360x768
or: xrandr --output HDMI-0 --auto --primary --output DVI-1 --off

Also, a similar issue occurs even with glamour + dri3 (and maybe exa + dri2 etc., but I haven't tested this) for:
xrandr --fb 3840x1200 --output HDMI-0 --mode 1920x1200 --scale-from 3840x1200 --output DVI-1 --off
And the scaling does not work. It recognizes the fb change (the panel pager reflects this), but the scaling does not change. I've filed a bug for this some time ago, though things have changed a bit since then: https://bugs.freedesktop.org/show_bug.cgi?id=80678
