Public bug reported: I am using 12.04 LTS (Lubuntu) on a Sony VAIO YB3V1E/S with AMD E-450.
If I tell xscreensaver to "quick power off the display in blank only mode", then when the screen is blanked, the backlight stays off only for a minute or two and then the backlight comes back on. I am usigng the fglrx driver from the Ubuntu repository. I think this is an X server bug because if I turn dpms off in the xorg.conf, and then ssh into the blanked machine and use vbetool to turn off the backlight, then it doesn't come back on by itself. ** Affects: xorg-server (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/991973 Title: backlight comes back on after screen is blaned and powered off To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/991973/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
