** Description changed:

- 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.
+ [Problem]
+ When LVDS disabled via gnome-display-properties or xrandr, instead of turning off it displays sequentially changing colors on the full screen like on a display test.

  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).
