[Bug 887046] Re: External monitor won't turn off laptop display

 

** 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.
+ 
  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).
