photo with screen corruption
I have these two (old) GPUs:
00:0d.0 VGA compatible controller: NVIDIA Corporation C61 [GeForce 6150SE nForce 430] (rev a2)
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV370 [Radeon X300]
After startup my desktop runs on the nvidia gpu.
I enable prime with these commands:
xrandr --setprovideroutputsource radeon nouveau
xrandr --output VGA-2 --auto --output DVI-1-0 --right-of VGA-2 --mode 1280x1024
It seems to almost work, but the monitor connected to the radeon gpu is very corrupted, see attached image.
Software:
linux 4.5
xf86-video-nouveau 1.0.12
xf86-video-ati 1:7.6.1
xorg-server 1.18.3
xfwm4 4.12.3 with compositor enabled
