I had the same issue. I solved it with the follwing lines in my xorg: Section "ServerFlags" Option "AllowEmptyInput" "false" EndSection Section "InputDevice" Identifier "Default mouse" Driver "mouse" Option "Device" "/dev/ums0" Option "Protocol" "auto" Option "SendCoreEvents" "true" EndSection It seems to be a bug in hal. GuillermoYes, I tried that but get an error, so some other program (hal?) appears to have claimed /dev/ums0
