Bug Description

To reproduce, install 12.04 LTS onto a Lenovo E525 with the ATI video card.
Run the script /usr/share/checkbox/scripts/xrandr_cycle

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.

It could be reproduced when you try to set the resolution to 800*600

After updating the system to 3.2.0-56
the xrandr script works fine with the same radeon 6.14.99 driver
And you can switch to the lowest 800*600 resolution setup as well.

Therefore I'll set this bug as Fix Released, if you are still having this issue, please feel free to open a new bug.
Thanks
