The bug seems to be somehow related to one component used in the gnome environment. With the following procedure I sometimes the arrow keys to work with gnome-session: 1. start Xephyr (using second keyboard/mouse than the main X-server). No window manager or other program is started yet in Xephyr. 2. Press the up-key several times on the second keyboard (used by Xephyr) 3. wait some seconds (5 to 10) 4. start gnome-session in Xephyr --> up-key works normally -- Xephyr keyboard layout broken https://bugs.launchpad.net/bugs/585564 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
