When I connect it and reboot, the image is set to 1024x768 on both montiors and the image is mirrored. Is there any change to switch the internal and external monitors to different resolutions and expand the desktop on both screen?
Which is the maximum resolution the gma500 is cappable of? My internal montior uses 1367x768.

Hi, I'm using vaio P in archlinux, so it might not 100% the same but this is what I did. I need to use modesetting driver instead of fbdev one (I don't know what is the default for ubuntu).
Then I query xrandr for supported external resolution and display name. (I don't attach it to any external monitor when I did this
Code:
[min@sakura xfce4-volumed]$ xrandr
Screen 0: minimum 320 x 200, current 1600 x 768, maximum 2048 x 2048
LVDS-0 connected 1600x768+0+0 0mm x 0mm
1600x768 30.0*+ 59.9
1368x676 59.7
1280x614 59.7
1256x600 59.8
S-video-0 disconnected
S-video-1 disconnected
VGA-0 disconnected
finally set the resolution
Code:
"xrandr --output LVDS-0 --mode 1600x768 --rate 59.9 --output VGA-0 --mode 1920x1080 --below LVDS-0"
As you can see the maximum resolution is 2048x2048, so you need to stack it top and bottom instead of left and right
