I just upgraded from 10.04 to 10.10. However, the screen resolution is changed and the I can't choose the right resolution. Is there any way to fix this?

Are the required video drivers for your video card installed (or available)?
Check by running 'Hardware Drivers' from System/Administration.

If you can't find the drivers following the advise in above post:

Which graphics driver is there?


lspci | grep VGA

We would also want to make sure that you are not running Ubuntu as a Virtual Machine and it is a proper install?

This is what I got when I put in "lspci | grep VGA"
02:00.0 VGA compatible controller: ATI Technologies Inc M96 [Mobility Radeon HD 4650]This is not a virtual machine. It is a dual-boot Windows 7 & Ubuntu.

I assume it is installed properly

On Ubuntu 10.04 LTS, the resolution was correct. It was only when I upgraded to 10.10 that I had this problem. Additional Drivers.png (http://ubuntuforums.org/attachment.php?attachmentid=177953&stc=1&d=1291935337)

Try reconfiguring the graphics.


sudo mv /etc/X11/xorg.conf /etc/X11/xorg.conf.old

It if says file not found, ignore and proceed to the next one.


sudo dpkg-reconfigure -phigh xserver-xorg

Reboot.

A workaround I used in openSUSE for a nVidea card:

In the xorg.conf file there often are several resolutions listed.
I used to remove manually all the resolutions not needed.

Maybe this works for you?

Note: this workaround can damage your v-card if used the wrong way!

if it is a VM how would one fix it?

I ask becauase I am in a VM and stuck at 800x600 and can't seem to make it go higher.
trying to figure out if there's a way to trick it into thinking I have a higher resolution monitor?

Install VMWare Tools.

Or Virtualbox guest additions, whichever applicable.

my bad, I should have stipulated. I'm running a Citrix VM, not VMWare. But with that said I'll double-check the senserver tools.

It works. Thank you so much.
