I have successfully aplied the patch https://raw.github.com/liskin/patches/master/hacks/xserver-xorg-video-intel-2.20.14_virtual_crtc.patch on the code of the 2.21.6. The driver works, but does not show VRITUAL in xrandr. Anythign I could do to have this working?
OK, cool, indeed after setting accel method, it works. Thanks!
@radaczynski: I'm hitting the same problem. How do you "set the accel method"?
in the xorg.conf file, here's mine (/etc/X11/xorg.conf):
Option "AccelMethod" "uxa"
Option "Virtuals" "2"
@radaczynski: Works for me, thank you so much!
