No keyboard, nothing, just a blank screen. Anyone with the same problem? I have the latest Radeon driver package installed from AMD and it works. Except for this case. Display Power Management is turned off. Now I try to turn off the PowerDevil... Last edited by Michael on Thu May 28, 2009 10:48 pm, edited 1 time in total.

Also, which graphics drivers are you using? Also, have you configured Powerdevil to perform anything else when shutting down the screen? KDE Sysadmin [img]content/bcooksley_sig.png[/img]
