I am using open-source drivers for my ati card. If I connect an external
monitor to my laptop (acer aspire 8942g) it connects and I can see a
clear imagine, but if I try to turn off my laptops display via gnome-
display-properties the external monitor continues working, but my
laptops display starts to show my sequently changing colors on the full
screen like on a display test. Sometimes I start my laptop and and the
laptop display shows normal sometimes the resolution is low and
sometimes it again shows these colors (always with my external monitor
connected). I had ati proprietary drivers installed once and everything
worked fine and I could turn my laptops display off, but not on the open
source drivers. Also turning my laptops monitor with Fn+F6 does work,
but after I press any key on the keyboard it turns on again.

If I type this command:

xrandr --output LVDS --off

the same thing happens like using gnome-display-properties, which means
different colours (test screen like).

** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu)
