I installed 13.1 64bits, and since the Nvidia repo is not up yet, i decided to play with the Nouveau driver, to try and set-up dual monitors.

I ran arandr and got this script:

Code:
#!/bin/sh
xrandr --output VGA-1 --mode 1680x1050 --pos 1680x0 --rotate normal --output DVI-I-1 --mode 1680x1050 --pos 0x0 --rotate normal --output HDMI-1 --off
I have two identical monitors, one is to the right of the other.

When i run this script I do get the desired output except for one little quirk : The screen's refresh/update doesn't seem to work on the right monitor (VGA). if I move an application's window around, it will leave a trail of all the previous windows and not refresh the screen. I'm attaching a sample screen capture:

Any ideas hot to fix it ?

thank you
