New update ubuntu 18.04.4 LTS causes me log out of my account multiple times

Question

Before the update every time I logged in I used to disable my laptop's touchscreen. But since the new update I am not able to disable the touchscreen.

Command xinput disable 9 doesn't works anymore. Someone please help. I have other methods too but none of them worked.

And also I get logged out my account and all applications gets closed automatically and I have to re login. It usually happens when I use the touchscreen. This is only happening after this new update.

Ctrl+Alt+F3, login, then what does xinput --list show? – Gryu Mar 06 '20 at 22:16 — Gryu, Mar 06 '20 at 22:16

Edit /usr/share/X11/xorg.conf.d/40-libinput.conf file and in

Section "InputClass"
        Identifier "libinput touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

replace libinput in driver section to evdev, so it will be:

Section "InputClass"
        Identifier "libinput touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
EndSection

Then restart and try to login.

People here did the same for evdev configuration making it invalid by replacing evdev to libinput. In this way they disabled touchscreen.

If you have /usr/share/X11/xorg.conf.d/10-evdev.conf file, then change evdev to libinput in Driver section for this case.
