Hi, my notebook thinkpad w500 has two video cards, intel / radeon. When i test some 3d games by wine or some videos by mpv using dri_prime=1 to dynamic enable radeon card, the game/video window always tearing, see bug report https://bugs.freedesktop.org/show_bug.cgi?id=76367. So i try to start second xserver directly use radeon card, command like this: $xinit /usr/bin/openbox-session -- :1 -ac -configdir radeon (/etc/X11/Xwrapper.config already changed to allowed_users=anybody) I put 20-radeon.conf into /etc/X11/radeon, which is: Section "Device" Identifier "radeonGPU" Driver "radeon" BusID "PCI:1:0:0" Option "DRI" "3" EndSection The basic thouhgts is default xserver using intel+radoen by dri prime that is nice technique still needs upgrade, start second xsever just using one video cadr(intel or radeon) as needed. If i just put 20-intel.conf into /etc/X11/radeon (just use intel IDG), the second xserver runs ok. Just using radeon DIS the second xserver started without any conntected output. run 'DISPLAY=:1 xrandr' could confirm that, all disconnected, so it's black screen on second xserver vtn, and default xserver vt7 still ok. Am i missing something to config second xserver using radeon DIS, or it's not possible?
Please attach the Xorg log and the output of dmesg and xrandr corresponding to the problem.

My basic thouhgts is default xserver using intel+radoen by dri prime, start second xsever just using one video card(intel or radeon) if needed. Both of two xservers using the same physical display, whatever internal or external. Here is my debug message when second xsever just using radeon card: ~$ DISPLAY=:1 xrandr Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 DVI-0 disconnected (normal left inverted right x axis y axis) LVDS-1 disconnected (normal left inverted right x axis y axis) DisplayPort-1 disconnected (normal left inverted right x axis y axis) VGA-1 disconnected (normal left inverted right x axis y axis) ~$ xrandr (intel+radeon dri prime) Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 32767 x 32767 LVDS1 connected (normal left inverted right x axis y axis) 1920x1200 60.00 + 59.95 49.85 (...)
