Ubuntu is running in low graphics mode after installing ATI driver

Question

I have Ubuntu, version 12. I installed ATI driver and I'm getting an error running in low graphics mode.

I needed to install the driver because every time I update or upgrade Ubuntu, right after installing the packages the system runs in low graphics mode.

The answer here also couldn't help me.

Graphics card model: ATI Radeon HD 3600

Installing fglrx also didn't help. The ATI driver is still installed and it still runs in low graphics mode. What should I do?
