Thanks for your help but didn't help to resolve anything : I did the 'sudo dpkg-reconfigure xserver-xorg' thing but I end up having some kind of virtual desktop in 1280x1024 (the screen slides when the mouse touches the borders).
I tryed to do 'sudo ddcprobe | grep monitorrange' wich gave me monitorrange: 30-76, 50-75 I put those values in my xorg.conf and add Modes "1600x1200" "1280x1024" "1280x960" "1024x768" "800x600" "640x480" But I end up having the same virtual sliding behavior as above, 1280x1024 top. The problem on screen flashing when going into a console and coming back to X still stands. -- Intel i965 doesn't have an appropriate driver https://launchpad.net/bugs/80611 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
