I had an issue that came about suddenly while working.  Every now and then my cursor would jump to the upper right corner and lock to the taskbar.  I couldn’t find any pattern to explain it.  I tried:

• activating/deactivating the trackpad
• swapping my mouse out
• cleaning my touchscreen
• rebooting
• deactivating extensions

The issue persisted.  I noticed that my touchscreen wasn’t responding, so as a last step, I tried temporarily deactivating my touchscreen.  The problem then went away.  After a reboot, my touchscreen worked properly and the cursor no longer jumped.  I have no explanation as to why, but here is how:``` xinput --list ``` That will give you a list of inputs with IDs. The touchscreen entry should be pretty obvious. Mine is ‘Synaptics Large Touch Screen’. Note the ID. It should be a single or two digit number.``` xinput disable {#} ``` (Where {#} is the ID number from the list.
