disable coherent mode

you might also try disabling coherent mode.  some monitor's don't like it. You
can disable coherent mode via xrandr:

xrandr --output DVI-0 --set coherent_mode 0
xrandr --output DVI-0 --mode 1024x768
xrandr --output DVI-0 --mode 1280x1024

You can also try this patch which will disable coherent mode by default.
