This bug also affects me on a Desktop. With "xset dpms force off" the monitor goes off for 2s but after 1s the backlight goes on again. "sudo vbetool dpms off" has worked only ones.
Also, I think the affected package shouldn't be "kdebase-workspace (Ubuntu)", maybe it is dpms or the drivers fault. Maybe it is also related with bug 37364 -- DPMS doesn't turn off the screen https://bugs.launchpad.net/bugs/288318 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
