This issue had been reported before with several possibilities to the error.

This issue have several possibilities.

One of the most common possibility is hardware incompatibility. If you are using a latest version laptop, the hardware may not be supporting Ubuntu 10.04 operations.

Second one is, your lightdm may be crashing. This is the program responsible for display systems in Ubuntu.

Different people have different solutions for this issue like http://ubuntuforums.org/showthread.php?t=1477795 https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/549632 https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/529882

You could try one of the solutions mentioned in these thread.

My opinion is, when you experience this issue, Try to go to one of the non GUI terminals of Ubuntu. This could be achieved by using the key combination alt+ctrl+(f1/f2/f3../f6). Once you get hold of one of these screen, login into the terminal. Then restart the lightdm using

sudo service lightdm restart
