screen resolution stuck at 640x480 after update

[i_heart_pandas]

i updated my computer this morning (Ubuntu 8.04 x64 with a a native resolution of 1920x1200), then after the restart it prompted me about no hardware acceleration and now i can't get the resolution above 640x480 which is unusable.

I've tried modifying xorg.conf but can't get it to work

(i have a 8800gtx btw)

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by failsafeDexconf, using
# values from the debconf database and some overrides to use vesa mode.
#
# You should use dexconf or another such tool for creating a "real" xorg.conf
# For example:
#   sudo dpkg-reconfigure -phigh xserver-xorg

I am running wubi 8.04 (HH) using an Nvidia 5200FX graphics card (HP 514n system w a Celeron 2.2GHz CPU). This system is networked with two other systems, and also has a Belkin Flip switch to share a second desktop system that is wirelessly connected to this one. Graphics used to work under HH just fine and the video card (256MB) works fine under WinXP.

I can switch back and forth between systems using the Belkin Flip switch under WinXP just fine. I can boot Wubi 8.10 (TT)--which I downloaded recently on my other desktop, a Compaq AMD 64X2 with an GeForce 8600GTS card. Wubi 8.10 runs just fine on the Compaq, but Wubi 8.04 only runs now at 640x480. I have followed all kinds of different threads, tried different fixes and nothing works on my HP desktop. I repeat, it used to work just fine. Is there a good step by step fix for setting my screen resolution to 1024 x 768? Everyone seems to suggest one or two things, nothing comprehensive and clean step by step.

It's this kind of thing that makes me want to stay with Microsoft, even though I have found OpenOffice a very good replacement for MSOffice. Fixing this display issue should be easy, but so far no fixes under Ubuntu seem so. The length of this should tell you how frustrated I am...Thanks, Kent.

Hi, couple of days ago I downloaded and installed some updates. My screen resolution went to 640x480. So I went System->Preferences->Update screen resolution. The previous higher settings were no longer available.

I tried the detect displays - nothing happens when clicking the button so ..

I have onboard graphics Intel 865G so I checked to see if I had the latest.
sudo apt-get install xserver-xorg-video-intel

Had the latest so checked /etc/X11/xorg.conf and there were no settings present in the Section "Screen" so I updated it with the following

Section "Screen"

I used sudo gedit /etc/X11/xorg.conf and saved the changes.

ctrl-alt-backspace restarted X and I had 1680 back.

Went back to System->Preferences->Update screen resolution and chose the setting I was after. For some reason the screen only displayed in the top left of the monitor so I restarted Ubuntu, logged in and now all is good again.

Only a newbie to Linux so there is probably a better way to do the above but thought it might add to the discussion or a solution for someone.

Thanks to everyone else out there that posts their issues but especially those who say how it was fixed.
