ubuntu 10.10 dvi problem

hey i recently installed ubuntu 10.10 on my beaglebored xm rev B
everything went fine in till the power connector got knocked and the
bored lost power. when it rebooted to screen stopped outputting
anything at all. i tried to do some of my own debugging by looking at
the serial data but it goes dead as soon as the kernel loads.

thanks in advance

If you edit/regenerate your boot.scr file with
"console=ttyS2,115200n8" or "console=ttyO2,115200n8" (O for 2.6.36 and
greater) in the bootarg you'll be able to debug more..

I am having a problem similar to Matthew's, I think I may have run
into the same issue.
I am using Ubuntu Maverick, installed on an 8G SD card by these
instructions: https://wiki.ubuntu.com/ARM/OMAPMaverickInstall.
On the first boot, the DVI output works. After rebooting several
times, the DVI output still works. After removing and replacing the
power, the DVI output fails to work.

"console=ttyS2,115200n8" or "console=ttyO2,115200n8" (O for 2.6.36 and
greater) in the bootarg you'll be able to debug more..

I have modified boot.scr, adding the options
earlyprintk console=ttyS2,115200n8 serialtty=ttyS2

The DVI display does not recognize any signal from the beagle board.
The serial output is copied below, then nothing.
Any suggestions as to how to convince Ubuntu to continue sending DVI
output would be greatly appreciated.
