How do I change screen resolution?

Asked by Keith Glossop on 2010-06-03

I am running Ubuntu 10.04 which I loaded yesterday and the screen resolution was good. Now however it is only offering 640x480 or 320x240 with a 50HZ refresh Rate which is awful to use. I have a Ge-Force 5200 installed which gave me superb performance under all Windows platforms.
Can anyone please help so that I can enjoy my computer again?

Hey Keith,


sudo nvidia-xconfig

gksudo nvidia-settings

See if that helps.

Hi wojox, many thanks for the fast reply. I have done what you advised and the nvidia settings were corrupted. The system loaded new settings but it is still only offering me 640x480 as the best resolution. Also as I play with the settings screen the screen jumps all over the place and it is difficult to select anything because as soon as you click on it it jumps somewhere else. Is there any way I can dump the nvidia settings completely and try something else?

Hope this makes sense

Can you get othrer higher resolution by using ur onboad VGA card? If "yes" What is it?

go to system - admin. -package manager - then search -enter nvidia-xconfig , then mark for removal . click the green check mark in the top role to apply . then restart the pc . after restart go to system - preference - monitors set the resolution to what you like . then let us know how it works .

System->Preferences->Monitor: do you have NVidia proprietary driver or free driver ?
What is the detected screen size ?
System->Administration->Hardware Driver: same question.
You can try to switch from one to another.

Thanks Guys. In the end I have swapped monitors with my other system and all is now fine. I am so impressed with the Ubuntu community and all your help that I will NEVER buy Windows software again.

All the best
