garbled display on resolution 1280x800 Ubuntu Natty

Asked by Maria Boghiu

I did a fresh install of Ubuntu 11.04 from a LiveCD. Upon booting, it all worked fine. However, after booting again some time later my display suddenly changed to resolution 1024x768. If I go to Monitor>Settings and choose a resolution of 1200x800, the display becomes corrupt: it still displays as a 1024x768 image, but it is now shifted to the right hand-side corner of the screen (as opposed to a centred image as before), although the top panel stretches all the way across the screen.

Any ideas?

* The display works fine if I choose "Ubuntu Classic" for my session at the login screen. I've taken some photos but I don't see a way of uploading them..

Hmm, it looks like if I log in with Ubuntu Classic, then log out and login with Ubuntu (i.e. Unity), it works ok. But if I boot and go straight to Unity, it behaves as described above. Hope this helps.

Thank you.
