I have a rogue xinput device due to some OS error that sends key press signals even tough nothing is pressed thereby causing screen flickering and the loss of mouse focus.
The device is:
xinput list 8 Video Bus id=8 [slave keyboard (3)] This device is disabled Reporting 1 classes: Class originated from: 8. Type: XIKeyClass Keycodes supported: 248
How can I permanently disable it so it won't come back after restarting the machine?
OS is: Ubuntu 14.04.4 LTS
