Ubuntu - getting more screen resolution options
I installed Ubuntu on two different PCs, and in both cases, the default screen resolutions offered were lame! In both cases, the only one that worked was 800x600. Googling around revealed that I was not alone in this frustration. One evening I decided to give it another go, and now have, happily, got plenty of screen resolution choices to pick from, such as 1024x768, which I'm using now.
Here is what I did:
Well, first off, google up the specs for your monitor. In my case, I've got an old NEC MultiSync 5FGp. Googling turned up this:
NEC, MultiSync 5FGp, 17", 27-79kHz, 55-90Hz, 0.28mm
(you might not need this step) I then visited The XFree86 Modeline Generator and plugged in the horizontal sync and vertical sync info I found for my monitor. I took the resulting modeline and copied it down for future use.
Okay, now edit /etc/X11/xorg.conf. I used vim to do the editing, you can use whatever you like.
Scroll down and find the section that looks like this:
Identifier "Configured Monitor"
HorizSync 28-40
VertRefresh 43-60
Comment out those original values, and stuff in the values for your monitor.
Identifier "Configured Monitor"
#HorizSync 28-40
#VertRefresh 43-60
HorizSync 27-79
VertRefresh 55-90
In this case, you can see the values are quite a bit different from the default. Log out, log back in, and I bet you got lots of screen resolution choices now.
Okay, so if you don't, you need to toss in that modeline info from the Modeline Generator.

In the above sample, I stuffed in the "1024x768@75" entry in there. But I bet you dont' have to do that. I bet changing the horizontal sync and vertical refresh does the trick for you.
Well, at least it worked for me. No promises this will work for you.
