journal from running reverse prime from radeon
This may be a different problem, but when I try it the other way around by
adding /etc/X11/xorg.conf.d/20-radeon.conf with
Section "Device"
Identifier "Device0"
Driver "radeon"
BusID "PCI:2:0:0"
EndSection
Section "Device"
Identifier "Device1"
Driver "nouveau"
BusID "PCI:0:0:d"
EndSection
then X starts on my radeon gpu. Then I can do
xrandr --setprovideroutputsource radeon nouveau
and then
xrandr --output VGA-1-2 --auto --output DVI-0 --right-of VGA-1-2 --mode
1280x1024
then I get pretty gruesome messages in dmesg.</pre>
