As reported on this launchpad I can't figure out if bug is related only for mobility Radeon 7500 using opensource driver or not and if the main problem refers to "blank" or "black" screen. So I decided to open another bug report on https://bugs.edge.launchpad.net/ubuntu/+bug/154586.
If somebody conclude its a duplicate bug report, please feel free to change it.
