(EE) xf86OpenSerial: Cannot open device /dev/psaux
No such device.
I tried to cat /dev/psaux and /dev/input/mice and /dev/input/mouse0 ,
and all give a device not found error, which led me to believe the
kernel module was not loaded. But my dmesg contains
input: PS2++ Logitech Mouse on isa0060/serio1
With the kernel input layer, there are three components to the mouse
driver now. One is 'psmouse', which you already have loaded. Another
is 'input', which is autoloaded. The third is the frontend,
'mousedev', which takes mouse data and produces an emulated PS/2
Intellimouse on /dev/input/mice - and optionally on /dev/psaux as well,
for backward compatibility.
Note that 'mousedev' is not strictly needed - if your applications can
deal with the 'event interface' instead, you can just load the 'evdev'
module and use /dev/input/event0 et al. as an alternate "front-end
driver" for mouse packet output. But normally you just want 'mousedev'
and /dev/input/mice.
