This is certainly related to this bug: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/145501
As it didn't occur in Feisty on my Toshiba Portege R200 (i810 driver) and apparently came in with Gutsy. I have these problems with Hardy (intel driver). If I press Fn-F5 enough times it works, but doesn't switch off the laptop screen any more. The toshset util switches correctly, but again doesn't switch off the laptop screen - just dims it. I think it must be due to some kind of switch towards multiple screen support with "xrandr" instead of xinerama, which doesn't work well with toshutils -- Fail to switch bwteen CRT and LCD https://bugs.launchpad.net/bugs/163877 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
