[mythtv-users] Projector display problems

I had a real fight a few months ago to get a decent display from my BenQ 
W100 projector. I never did managed to get a wide screen image 
outputting but spent so long trying that I settled on a 1024x768 image 
with wide screen 'display size' settings.

This worked ok, and still displays ok, but I've had a problem since 
upgrading to Ubuntu 7.10. The main GUI of Ubuntu works fine, but when I 
press CONTROL + ALT + F1 to log in without the GUI the screen can not be 
displayed. I just get an out of range or invalid message from my monitor.

I don't need to do this much, but do need it.

I can see the boot up of the machine when the computer starts, so it's 
not like that mode can't be displayed at all, and I know this used to 
work fine. But now going to CONTROL + ALT + F1 is invalid.

Also, the display seems fine in Mythfrontend, but when I watch tv or 
play recordings, I need to set the display to 4x3 in order for them to 
look right. This seems weird to me. Any ideas?

Can any of you in the know check out my xorg.conf file and tell me where 
I'm going wrong?

If anyone can get wide screen resolutions going on my projector then 
I'll be in your debt forever!
