Thanks for help,

i think , i have found a solution.

Use newest xf86-video-intel 2.99.917
Enable SNA (+virtual output)
Enable virtual output in the xorg.conf. (Option  "VirtualHeads"  "2")

Call follow line after X started

xrandr --newmode "1280x1024 at VIRT"  138.75  1280 1368 1504 1728  1024 1027 1034 1072
xrandr --addmode VIRTUAL1 "1280x1024 at VIRT"
xrandr --output VIRTUAL1 --mode "1280x1024 at VIRT"

with xrandr I see always the same resolution at the current value.
Also with connect/disconnect HDMI/DP.

Now I'm search a way to set this 3 line with the xrandr extensions library.

Best regards
  Johann
