Last 2 days...
I upgraded my Ubuntu 21.04 to 21.10.
Upgrading with internet with cool. But after installing process finished.
I got shocked when i login to mine fresh screen, the error shows me when ELAN TouchScreen just like
ghost!.
TouchScreen auto resize and change automatically.
Then i search at google. Then answer views not much what i needed.
Later 1 day with i facing error.
This is the command i used to close my ELAN TouchScreen.
$sudo edit /usr/share/X11/xorg.conf.d/40-libinput.conf
And search when i selected and highlight here like this.
One thing is [on] => [off]
On input TouchScreen.
