You have been subscribed to a public bug: I upgraded yesterday to 13.04 from Ubuntu Studio 12.10; running xfce4 and xfwm4. On a dual-monitor setup, I accidentally kicked out the DVI cable from one of the monitors and plugged it back in (this may have already happened once or twice without consequence; I can't remember if that was before or after the upgrade). This second monitor displays all windows correctly, and the mouse cursor is able to move between screens as usual. But none of the windows or other UI elements on the second monitor receive focus or respond in any way. Switching virtual desktops only switches the first monitor. Trying to move a window from the first monitor to the second monitor shows the mouse cursor on the second monitor but not the window contents (and the window gets "stuck" on the first monitor as though there is no second monitor).
Going to the console and back to X blanks out the second monitor, but the mouse cursor can still travel to it. NVIDIA X Server Settings no longer shows the second monitor, and Detect Displays does not fix that. ARandR shows both displays in its layout and allows both to be configured, until a new layout is applied, then the second display is completely disabled (mouse now properly stuck on first monitor) and not configurable. ** Affects: xorg-server (Ubuntu) Importance: Undecided Status: Incomplete -- windows on previously disconnected second monitor no longer responsive https://bugs.launchpad.net/bugs/1234334 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
