Description Nicolas VINOT 2012-07-14 15:33:15 UTC 
When using nouveau driver, resolution reported by the monitor is 1921x1201, whereas xrandr report 1920x1200.
The extra pixel leads to a blur screen.

Tested with xserver-xorg-video-nouveau 1.0.4-1, the problem is still present.

Resolution is wrong in console, and from the boot (plymouth KO) too
