I have installed Ubuntu 12.10 on my desktop. (Pentium 4, 80 GB hard disk, 2 GB RAM, 32-bit CPU.) And I have installed Windows XP.

I made a 40 GB partition for Windows and 40 GB for Ubuntu. I installed Ubuntu and it said "installation is complete" and asked me to restart. I restarted the PC and then logged in. After 1 minute I get a message like this:

The application compiz has closed unexpectedly.

Then I closed it. After that it just stays in a blank screen and nothing shows up.

What should I do?

This is a known bug in 12.10 but it may be exacerbated by the graphics sub-system on your motherboard, assuming you have a motherboard with integrated graphics from the chipset's north bridge.

It appears that the error is caused by some sort of a disconnect between Unity and certain graphics hardware. A great many people are running into this bug.

The short answer is that you need to go back to 12.04. When I gave up on 12.10 and went back to 12.04 I no longer got this error. Someone in another thread had suggested that using 2D graphics in 12.04 would fix the compiz problem but I had no issues with 3D in 12.04, in fact 2D didn't work properly.

What made no difference:

Upping the shared graphics memory: Still got the error in 12.10 but not 12.04. Using 2D in 12.04: Actually didn't work at all, graphics was all screwy.

This error happens only with certain graphics cards.
