How to fix “The system is running in low-graphics mode” error?

I have an ATI Radeon 3200 graphics card.

I just upgraded to 12.04 and I get the System running low graphics... error code.

Your screen, graphics card, and input device settings could not be detected correctly.

It is exactly the same problem as one or two previous questions. So I tried their solutions to run sudo apt-get install ubuntu-desktop and sudo apt-get install fglrx

The only answer I get is You allready have the latest sw.

And my problem with System running low graphics... is still there. So what do I do? For the time being I run the previous version. It worked perfectly. Gunnar

Solution 1:

I have recently experienced the same thing, I have Intel based graphics card.

I fixed the following way:

Ctrl+Alt+F2 to go to a shell

sudo apt-get update
sudo apt-get -d install --reinstall gdm
sudo apt-get remove --purge gdm
sudo apt-get install gdm

Choose gdm when prompted.

Then do a shutdown -r now and voila.

Let me know if it fixed for ya.
