If you want to disable a device which is connected or integrated with your computer on Linux you can check out xinput command. To view all xinput devices you can use the command “xinput list” the output of it on my desktop computer looks like this.
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Microsoft Microsoft® SiderWinderTM X6 Keyboard id=10 [slave pointer (2)] ⎜ ↳ Microsoft SideWinder™ Mouse id=11 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Power Button id=7 [slave keyboard (3)] ↳ Sleep Button id=8 [slave keyboard (3)] ↳ Microsoft Microsoft® SiderWinderTM X6 Keyboard id=9 [slave keyboard (3)]
As you can see here all of the devices has an id. For example if I would like to disable input from my mouse I should use the command down below.
xinput disable 11
To enable it you should use:
xinput enable 11
