Same problem here. I removed a 2nd mouse entry from my xorg.conf and restarted gdm and the behaviour is still bizarre.
Here's my current mouse configuration from my xorg.conf: #Section "InputDevice" # Identifier "Configured Mouse" # Driver "mouse" # Option "CorePointer" # Option "Device" "/dev/psaux" # Option "Protocol" "ImPS/2" # Option "ZAxisMapping" "4 5" #EndSection Section "InputDevice" Identifier "Generic Mouse" Driver "mouse" Option "SendCoreEvents" "true" Option "Device" "/dev/input/mice" Option "Protocol" "ImPS/2" Option "ZAxisMapping" "4 5" EndSection Running lsof on /dev/input/mice shows Xorg accessing the device twice. Is this correct behaviour? $sudo lsof /dev/input/mice COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME Xorg 5578 root 14u CHR 13,63 2054 /dev/input/mice Xorg 5578 root 15u CHR 13,63 2054 /dev/input/mice Thanks -- Mick Timony --- The trouble with computers, of course, is that they're very sophisticated idiots.
