Package: xserver-xorg-video-intel Followup-For: Bug #787241 Could you try: . Switch to VT . Log in as same use as X session on VT . run 'sleep 6 ; DISPLAY=:0 xrandr' on VT . switch to X VT before 6 seconds have elapsed, then switch back after 6 seconds have elapsed . Check output to see what mode your display is reporting . Possibly fix with 'xrandr --display FOO --auto' ?
