You have been subscribed to a public bug: I am running unity system compositor on my desktop in dual screen mode with Intel HD 2500 graphics.
When I play video, even when it's halted and the media player window (vlc and smplayer) is on another work place, the screen flickers black. I was able to find the following messages in /var/log/Xorg.0.log: [ 8967.357] (II) Setting DPMS mode for output 1 to 0 [ 8967.884] (II) Setting DPMS mode for output 3 to 0 [ 8972.730] (II) Setting DPMS mode for output 1 to 0 Watching the file with tail -f gives one or two new lines of these messages after each flicker. I experience this only on my desktop in dual screen mode, not on my laptop that also uses Intel graphics (HD 4000) and is currently running saucy. Totem and mplayer run from terminal are not affected. ** Affects: mir Importance: Medium Assignee: Robert Carr (robertcarr) Status: Confirmed ** Affects: unity-system-compositor Importance: Medium Status: Confirmed ** Affects: xorg-server (Ubuntu) Importance: Medium Assignee: Robert Carr (robertcarr) Status: Confirmed ** Affects: unity-system-compositor (Ubuntu) Importance: Medium Status: Confirmed ** Tags: pm xmir -- [xmir] Screen flickers black during video playback on Intel graphics in dual screen mode (DPMS mode changes constantly) https://bugs.launchpad.net/bugs/1238886 You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
