Graphic problem with latest update

Asked by Neil Campbell

I upgraded to the latest version of Ubuntu 11.04. I am running an old HP/compaq nc6000 laptop. Previous versions of Ubuntu ran perfectly well on it. What happens now when I boot up everything is OK up to the login screen. After logging in the tune plays and then the screen "breaks up" and looks very pixelated. The mouse cursor is clear and when I roll over icons they activate but I cannot read the screen properly. This means I can't operate the laptop or use any applications.

Does anyone have a fix for this or a way that I can easily roll back the system to the last version that worked?

I am not sure about the Graphics card in the laptop. What I have found now is if I can get a browser up I can use it. It is just on the home screen that this problem occurs. Sometimes using the browser the screen 'breaks'

I am having the same issue. Using a Compaq NC6000 with 1GB RAM, I installed 11.04 and the graphics card could not display correctly. as delance said, the screen images were almost de-interlaced and spread all over the screen. I could see the images but just *Barely*.

I managed to muddle through the UI and find the software installer, I removed Compiz and now I see a clean screen, but there are no menu, tabs or anthing else. Just a screen with an image on it and a mouse. that's it.

Any ideas?

Thanks Matt

I have now solved it. Only yesterday though.

I had that issue too. What you need to do is to get to "System Settings" then the "system section" and open the "login screen settings". At the bottom you will find " select ..... as user setting" change it to either "user defined session" which you can then change at login or the one that works is "ubuntu classic (no effects)"

I hope this helps as I am sending this from a Compaq NC6000 with 1GB RAM, using the ubuntu classic (no effects) setting and everything seems to work OK.
