I can reproduce the issue by playing a video using vlc (both mp4 and flv, probably other formats too).
€ vlc --version VLC media player 2.1.4 Rincewind (revision 2.1.4-0-g2a072be) VLC version 2.1.4 Rincewind (2.1.4-0-g2a072be) Compiled by buildd on brownie.buildd (May 17 2014 14:52:46) Compiler: gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1337886 Title: xset -q intermittently reports wrong DPMS stats To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/x11-xserver-utils/+bug/1337886/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
