I have a similar issue, but in my case simply plugging in a headset "steals" the mouse so I'm unable to switch between windows using mouse or do anything else. Keyboard continues to work though.
The problem is described here: http://ubuntuforums.org/showthread.php?t=1975696 and a workaround is posted here: http://www.rodneybeede.com/Plantronics_Savi_7xx-M_and_Linux_mouse_or_lockup_problems.html The device presents itself as an usb sound card, a mouse and a keyboard. To make X11 ignore the keyboard and mouse features (which are fine in windows but Xorg does not like it), I added this to xorg.conf: Section "InputClass" Identifier "Plantronics" MatchVendor "Plantronics" Option "Ignore" "true" EndSection The workaround works great for me -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-evdev in Ubuntu. https://bugs.launchpad.net/bugs/1006156 Title: Mute button on USB headset steals and holds on to mouse focus To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-input-evdev/+bug/1006156/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : [email protected] Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
