I have already described how to disable the touchpad when an external mouse is connected using the udev device manager, but today I want to share a simple shell script that I am using on Dell XPS 13 to disable/enable the touchpad using a single keyboard shortcut.

Recently I needed to update integrated Intel graphics drivers to gain access to more recent OpenGL extensions. Packages available by default in base system do not provide such functionality, so I used Updated and Optimized Open Graphics Drivers as it is built almost simultaneously with the latest updates.
