Touchpad Random Jumps
Hi,
I use Linux Mint with Lenovo Thinkpad E490 for 5 months.I have a problem these days with my touchpad.
Problem:Cursor jumps randomly.But this is strange because this promblem don't happen in login screen or desktop.it's happen when I open browser or a file.I updated drivers and system (I switch to libinput and nothing changed).I don't update bios (maybe problem is this,but I scared to hurt my laptop).No damage or drop.
