Public bug reported: With an updated Kubuntu 8.10 when running "xset dpms force off" sometimes the backlight stays on, and sometimes the backlight goes off for 2 seconds, and after that the backlight turns on again. Also configuring the "Power Control" under "Display" in "System Settings" from KDE 4.2 doesn't work, the backlight remains on.
With "sleep 1; xset s activate" nothing happens, but the second time it works. And only with "xset s activate" the backlight doesn't turn off. "sudo vbetool dpms off" works only the first time, the next time it doesn't make anything. 00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics Controller (rev 02) ** Affects: ubuntu Importance: Undecided Status: New -- xset dpms does't turn off backlight https://bugs.launchpad.net/bugs/332308 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
