X11 dual dispay with HDMI and EVM-LCD?

Hi,

I'm experimenting a bit with the new ti81xx xserver driver, that supports dual display. I already tried HDMI as main display + SVIDEO as secondary/extended display- That works quite well.

 

The question now is: How to get the ti814x-EVM's onboard LCD to work in extended desktop mode in combination with a HDMI display?

I already tried, with the following entry in the xorg.conf, but it didn't seem to work:

 

Section "Device"
    Identifier "TI8148"
    Driver "ti81xx"
EndSection

Section "Monitor"
  Identifier "HDMI"
  ModeLine "1920x1080"  148.500 1920 2008 2042 2200 1080 1084 1089 1125 +hsync +vsync
  Option "PreferredMode" "1920x1080"
  Option "Enable" "true"
EndSection

Section "Monitor"
  Identifier "LCD"
  ModeLine "800x480" 33.500 800 864 889 810  480 490 503 490 -hsync -vsync
  Option "RightOf" "HDMI"
  Option "PreferredMode" "800x480"
  Option "Enable" "true"
EndSection   

 

If you have any tip, I'd be happy to give it a new try. I'm not really sure about the modeline for the LCD.

BTW, I even tried to use the LCD as main display. The result was, let's say, not really satisfying. I can't get the LCD to display the whole desktop on my test system. It's always a bit blurry with strange colors and only showing part of the desktop.

 

Thank you very much in advance for any hints!
