One other option is to check to see if there are any xorg.conf backups in /etc/X11. But, really, if you're going to just do things at random, there's not a lot we can do for you.
I wasn'tdoing things at random - I added a few lines that looked something like

SubSection "Display"
Depth 24
Modes "1920x1080_60"
EndSubSection

to the file, but apparently in my current lack of sleep mode I must have accidently deleted some other crucial line or added something I shouldn't have.

I nuked the partition, and I'll start over tomorrow.

I'm back again --- I've successfully enabled 720p, but not 1080p. Both resolutions are configured the same way (using gtf) and were input the same into xorg.conf, but 1920x1080 does not show up.

Any ideas?

Section "Monitor"
DisplaySize 340 270
HorizSync 30-80
Identifier "Monitor[0]"
ModelName "LVM-42W2"
Option "DPMS"
VendorName "WDE"
VertRefresh 43-75
Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync
ModeLine "1280x720_60.00" 74.48 1280 1336 1472 1664 720 721 724 746 -HSync +Vsync
UseModes "Modes[0]"
EndSection

-and-

Two suggestions:

check whether the vertical and horizontal refresh rates in your xorg.conf are correct; if they are too low, you won't be getting the highest resolutions; but be careful, if they are set too high, you'll get a blank screen...

you should also have a look at the lines under "display"; the higher resolution should be inserted there as well.

Do make a copy this time before you start experimenting:

cp /etc/X11/xorg.conf /etc/X11/xorg.conf.bak

If you do get at blank screen, press ctrl+alt+backspace, sign in as root and replace the old xorg.conf:

cp /etc/X11/xorg.conf.bak /etc/X11/xorg.conf

Thanks. I'll be using that backup restore line, as I screwed my xorg.conf AGAIN. (but this time I made a backup!! )

I'll get the specific refresh rates from my windows nvidia driver and make sure I have everything in the right place in xorg.conf as you said.

*goes to repair xorg.conf*

Careful: I was talking about the refresh rates of your monitor. That can make quite a difference: my GPU can support up to 2560x2048 while my monitor stops at 1280x1024. If I use the first, I can be pretty sure I'll be admiring a blank screen before long.

Also, the line I gave to replace the back-up may need to be adjusted: it assumes your back-up is called xorg.conf.bak and that it resides in /etc/X11. If that's not the case you'd use:

cp /XXXXX/XXXXX/XXXXX /etc/X11/xorg.conf

where the XXXX need to be substituted to reflect the proper name and location of your back-up.

You will probably have to drop the refresh rate down.

[fred@127 ~]$ gtf 1920 1080 60

# 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
Modeline "1920x1080_60.00" 172.80 1920 2040 2248 2576 1080 1081 1084 1118 -HSync +Vsync

If I remember right the pclk is how fast the video card bus is running (screaming in this case).

[fred@127 ~]$ gtf 1920 1080 55

# 1920x1080 @ 55.00 Hz (GTF) hsync: 61.32 kHz; pclk: 156.99 MHz
Modeline "1920x1080_55.00" 156.99 1920 2032 2240 2560 1080 1081 1084 1115 -HSync +Vsync


It all depends on how fast the card can crank.

I think I mentioned this before but nvidia just(this week?) release a new linux driver that "fixes" a lot of issues with widescreens and refresh rats.

w00t! FINALLY!

Thanks for everyone's help. The problem was that my xorg.conf file differed slightly from the examples posted, but it seems to be working now.

Time to learn me some linux!
