Ubuntu – How to adjust mouse sensitivity on Dell Mini9 running Ubuntu

You can manually disable an input device via:

xinput set-int-prop "B16_b_02 USB-PS/2 Optical Mouse" 'Device Enabled' 8 0

and reenable it via:

xinput set-int-prop "B16_b_02 USB-PS/2 Optical Mouse" 'Device Enabled' 8 1

You can get the list of device names via:

xinput list

If you want to automate the whole process you could write a script to listen to HAL, which will tell you when devices are plugged in or removed. As a starting point you can have a look at xboxdrv-daemon.py

To clarify, to remotely administer the most basic level of hardware (hard reboots, BIOS settings / update) you want a "Lights Out Management" (LOM) card, which is an embedded server with its own processor on a card in the server, or a KVM-switch type solution.

For ordinary everyday Operating System level (i.e. Linux) administration, using remote text access such as provided via ssh. Yes, it will be annoying to learn all the commands and flags in the beginning, but it is quicker, and less painful than working daily via a remote graphical administration in my experience. I've been able to support remote systems in exotic locations using ssh for routine administration on high-latency (1000ms) 64kps or less network connections.
