Hi All
New to this forum
Just installed Quantal 12.10 armhf on a Beaglebone (not BeagleBoard) factory-equipped with an Ampire AM640480G2 touch monitor supporting 640x480 resolution
( http://elinux.org/BeagleBoardUbuntu )
After LXDE was installed, graphic desktop environment starts at 800x480 resolution and there is no other resolution to choose,
Pratically, the desktop environment is clearly displayed, but I can see only the 640x480 area allowed by display hardware
All I tried to change resolution manually ( https://wiki.ubuntu.com/X/Config/Resolution and many forums ) failed : xrandr --output <> --mode<> = xrandr: configure crt 0 failed
Probably something during boot tells the system that a 800x400 monitor is present instaed the right 640x480
Any idea on what to try ???
Thank you very much
