Xenophon, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com /daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p xorg REPLACE-WITH-BUG-NUMBER Thank you for your understanding.

All works well until I decide to switch off my AVR (while leaving Kubuntu on). When I switch it back on, I get nothing on my display.
