Hello, now i have compile 2.99.917 and enable VirtualHeads in the xorg.conf.
xrandr --newmode "1920x1080" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 xrandr --addmode VIRTUAL1 "1920x1080" xrandr --output VIRTUAL1 --mode "1920x1080" now it looks like it works. The resolution is always 1920x1080, even if I connect / disconnect DisplayPort or HDMI Monitor. Can I put this settings into the xorg.conf ? Or is xrandr the only way ?
