i have just installed the newest version of ubuntu. I was using fedora core4 with no problems up until I changed to ubuntu. My screen resolution is stuck at 640x480. I have read many threads on this but none seem to help. When I look at the xorg config file all the resolutions are showing but I can't change to any of them. Below is my config file. Please help if you can.

How do you try to change the resolution? What happens when you try to?
There might be some problems with the display, especially on a laptop. I had a similar problem with Debian, and by adding vga=771 as an install option, it worked fine. Maybe it is different in Ubuntu? There are also several more threads about this in the hardware and hardware>laptops sections.

I do not have this installed on a laptop. This is a dell dimension 3000 that dual boots between kubuntu and
Windows Xp. I am trying to change the resolution by way of the configuration window. I also screwed up in the previous post. I am running kubuntu. not a big fan of gnome but i would think that it shouldn't matter if it is gnome or kde. When I try to change the display the only option available is 640x480 and nothing else.

This section on Monitor should have two extra lines with HorizSync and VertRefresh ranges for your monitor. Mine are 30-62 and 50-70, respectively, but you have to research what yours are.

I have the exact same problem with ubuntu, except with a different monitor. I used Mepis before and graphics worked fine, but I had no sound (soundcard is also intel). Now that I have switched to ubuntu, the sound still doesn't work and I can't set a resolution > 640x480.

Have you tried 865patch ?

It is apparently needed to use Dell Dimension 3000 PCs and other models because of Dell's BIOS bugs.

Have you tried finding out the horizontal and vertical ranges for your monitor, then editing the /etc/X11/XFree86-4 file and putting in the appropriate HorizSync and VertRefresh rates.

Hey I had the same exact problem.

What aysiu said was right.

Well here's my solution to my 3000 Dell Dimension with 15" LCD Monitor. From just being able to set resolution to 640x480, I can now change my resolution to 1024x768.

In terminal type: gedit /etc/X11/xorg.conf

In /etc/X11/xorg.conf under the line Option “DPMS” (use the find option) just add:

HorizSync 28-49
VertRefresh 43-72

Save and reboot your system.

Here's where i found the post for the solution:

This should definitely work. Happy Linuxing!

I have posted on the same problem, and the common answer is to put in the vert and horizontal refresh rates. Unfortunately I can't find out what they are because my monitor is an old one (TUV 29J56G) and googling it doesn't do the trick. So

(a) Are there any values I could 'try' which would have a chance of success?

(b) Is there a resource anywhere likely to give me the refresh rates

(c) The computer also runs Window$ which has no problem hitting 1024x768. I know I shouldn't ask this, but is there any way I can find out from within Windows what the refresh rates are?

I really like the feel of Ubuntu but only having 640x480 is a pain in the ass!

here my etc/x11/xorg.conf file settings on kubuntu
my monitor runs 1024x768@75HTz ...

I also run KDE on Laptop IBM with 15'' monitor. Here are the specs:
If this wouldn't help, try booting with LiveCD and check the specs that it sets

This page in the Ubuntu Wiki will definately help:

I had the same problem when I installed Ubuntu and that is where i found the solution
