hey all i just installed ubuntu 7.04 and have a 8800gts graphic card and ive done all the updates but still it wont let me adjust the resolution past 1024X768 when i need 1440x900 does anyone know a way around this ? is it a driver problem ?
ive seen some posts like this asking for xorg.config to be posted so heres mine
Code:
# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the xorg.conf(5) manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg

Hi,
I too am new here! I have just had a simular problem but I wanted a lower res as 1280 has'ent doing my eyes any good. Just tring to set the res to 1024, just made the system go back to the logon screen...
Some one made a sugestion that pointed me in the right direction..
go to user/share/doc/915resolution for details and modes, etc.
then go to etc/default/915resolution to set the mode and res.
you should now be able to set the res from the desktop (right click) Checking the boxes with keep the settings. Don't do what I did and set the colour depth to 32 bit (by default??), takes a lot of memory and may have been the coause of my hang-ups. I have tried both a Radeon 9700 and a Nvidia FX5500 both seem to work fine..
Hope this might help.
Regards
Mel.

There are ubuntu how-to's on installing the nvidia driver on your system. I did those on my wifes computer but the nvidia settings manager from ubuntu didn't allow for setting resolution so I downloaded and installed the nvidia driver from their website and got it to work.
Don't remember how to setup ubuntu for compiling, you might already be ready dunno but need to do that first (instructions on ubuntu site as well as a few how-to's posted on the web). Select and downloaded the NVIDIA drivers from NVIDIA.com for your video card and install the driver with sh NVIDIA(ver). When it asks to update the xorg.conf for you say yes and start the GUI. Then you can use the nvidia setting manager to set the resolution to 1440x900.
If all else fails would install the nvidia driver from their site as a last resort. It was the only way i managed to get mine to work at that resolution.
Yes, tack your desired mode on as the first entry in that modes line. I was having issues with my refresh rate and screen size with Ubuntu as well, but after reconfiguring the X server manually, it was fine. Try and run, from the commandline, xorgconfig or X -configure or something and answer all the questions carefully; know the specs on your monitor's sync rates. Don't worry about the resolution; I pick line 11, as I know I'll be editing it later anyway and that one makes my job easier. Then go in and make a change like lord-fu recommended. good luck!
Next to lord-fu's proposed changes, you also need to modify the HorizSync and VertRefresh to reflect the capabilities of your monitor. Specifically your HorizSync is not correct; with the current value, you can only do 1024x768@60Hz max (and maybe, maybe, maybe, ...., 1152x864).
