Right, I just had this problem on latest Feisty. With gnome-power- manager set to never deactivate the monitor and gnome-screensaver set to never enable the screensaver, the screen blanked out after 20 minutes.
xset q: DPMS (Energy Star): Standby: 0 Suspend: 0 Off: 0 DPMS is Enabled Monitor is On Running "xset -dpms" seems to make it work, and xset q now shows: DPMS (Energy Star): Standby: 0 Suspend: 0 Off: 0 DPMS is Disabled I suppose a workaround is adding xset -dpms to your startup programs, in theory. Anyway, an upstream bug in gnome-power-manager linked above seems to deal with this exactly and even has a new patch as of a couple weeks ago, so I suppose I'll assign it to gnome-power-manager and set the upstream watch. ** Bug watch added: GNOME Bug Tracker #347242 http://bugzilla.gnome.org/show_bug.cgi?id=347242 ** Also affects: gnome-power (upstream) via http://bugzilla.gnome.org/show_bug.cgi?id=347242 Importance: Unknown Status: Unknown -- Screen blanks when watching movies https://bugs.launchpad.net/bugs/66257 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
