The bug that you have their has been resolved in 4.1 apparently so this must be a regression. As a temporary fix you may have to disable the screen locking and screensaver until this is investigated.
Go to: System settings -> Advanced tab (have you noticed that you use the advanced tab more than the General tab) and select power management. Select edit profiles on the left. I changed the performance settings as my laptop is usually plugged in when I watch a movie on it. Change the 'When the system is idle for more than' setting - I selected do nothing. The right hand pane is arranged in to a most strange vertical tab arrangement - select screen from that and set the screen not to power off. This suits me as when the screen is due to switch off it never works. That said I have probably tainted this report as from the 30 or so faults I have been involved with here none have been fixed until the new version of Ubuntu arrived. Infact the most critical one 284229 - I am surprised more haven't joined in there. -- [Kubuntu 8.10][KDE4.2.BETA2] Display locks automatic, when watching a movie ect https://bugs.launchpad.net/bugs/312583 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
