Bug Description
To reproduce, install 12.04 LTS onto a Lenovo E525 with the ATI video card.
Run the script /usr/share/
After the first few larger modes, video will become horribly corrupted and may not recover once the script tries to restore the original mode.
Essentially, the script determines what modes are availabe then switches to those modes to verify they work. Once the resolution gets small enough (less pixels), I noted severe screen corruption.
See the attached video. the fun really stars around the 30 second mark. On that video, the screen did not recover afterwards. I had to powercycle the machine to get the screen back to a usable state.

Video showing the xrandr_cycle test and the screen corruption. This occurred when using the default ATI radeon driver and I reproduced this three times in a row.
