355.11 Dual Monitor setup


Using x11-drivers/nvidia-drivers-355.11 breaks my setup. under Gentoo Linux.

Primary monitor is an HP w2207h (1680x1050)
Secondary Monitor is an Pavilion 22xi (1920x1080)

Staring KDE with the mentioned nvidia driver, the display on the primary monitor is shown wrong. I have a black border on the left which is about 1/6 of the screen (it looks squeezed).
The primary display is distorted, secondary is displayed fine.
Checking under X Server Display Configuration with nvidia-settings shows the correct values (1680x1050) and (1920x1080).

GFX Card is a GeForce GTX 660

Switching back to x11-drivers/nvidia-drivers-352.41 solves the problem.

Have you considered chucking xorg.conf entirely and letting xrandr configure automatically?

Hi Linubie,
