Retried again. The debugging command : kill -9 `pgrep "gnome-settings"`; gnome-settings-daemon --debug made the patch work for Unity 3D temporarily. I had a similar output as in comment #22 (xrandr Identified monitors...etc) and the monitor switch also worked. After logout/login, the patch is no more effective for Unity 3D. I also noticed that there was a second instance of compiz running with a huge memory consumption (if the debugging command is triggered).
Case 2 : The patch work fine in Unity 2D. (Fn+F1) and (Super + P) do work fine. -- You received this bug notification because you are a member of compiz packagers, which is subscribed to compiz in Ubuntu. https://bugs.launchpad.net/bugs/950160 Title: Keyboard function key to switch between monitors no more works To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-settings-daemon/+bug/950160/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~compiz Post to : [email protected] Unsubscribe : https://launchpad.net/~compiz More help : https://help.launchpad.net/ListHelp
