I was able to install and run Angstrom Linux on my Beagleboard xM.
But when I connected it to a LCD Monitor via HDMI to DVI-D cable, the
screen resolution that was coming is 640x480. With that screen
resolution it was very difficult to work as most of the windows were
exceeding the screen height.
Do we need to install some driver for graphics? or is this resolution
is the maximum that it supports.

Hi,
I currently have the same problem. Did you solve this?
I have tried changing the boot commands to a higher
resolution, as described in [1], but did not manage to
cause any change. But I will try again, using my real
kernel parameters from "cat /proc/cmdline".
I used another BeagleBoard xM Rev C which had its pre-installed Angstrom Linux and the resolution problem was solved. So I didn’t try to look more into it.
Can you provide the complete serial log and the contents of your uenv.txt?
Hello Jason,
that was a really good request. It helped me fix the problem!
Up to now, I did not know about uEnv.txt. I was using only a boot.scr
file, as described in [1] below.
Googling for uEnv.txt lead me to the thread "omap3_beagle: enable the
use of a plain text file named uEnv.txt instead of boot.scr" [2].
So I replaced my boot.scr file by an uEnv.txt just containing
"dvimode=1024x768-16@60" and that did the job!
(For the record, I am using a current Narcissus image with the
settings "simple", "Gnome", "Bootloader Files".)
