[solved] Disable Touchscreen before log in, HP spectre

HP Recommended
HP Spectre 13 Ultrabook
Linux

Hi, my touchscreen is currently broken (always detects touches top-right corner) so I need to disabled it.

I managed to do it on my desktop with help on this forum, but it is disabled only when I'm log in, not before.

Because of that, I can't navigate in the lock screens or the OS selection (dual-boot Windows10/Manjaro-kde) correctly.

I had looked on Bios, but didn't see anything to disable the touchscreen here.

 

So, is there a technique to disable the touchscreen machine-wide?

Do I need to deconnect the component from the board manually? Advice to do it without killing my machine?

 

PS : I can't get rid of linux (work related) but I could change distro if it can help. I think it annoy me enough to sacrifice Windows if it can solve the problem

Solution :

Main source :   https://unix.stackexchange.com/questions/127443/how-do-i-disable-the-touch-screen-on-my-laptop?rq=1

So, the touchscreen was disabled when Windows was booting but not for linux.

First disabling it temporarily (current session) :  I used xinput, in command line : "xinput list" to find the device id for the touchscreen, then "xinput disable <id>". Now I can work without the touchscreen doing random things.

 

Then, I added a rule for ignoring the touchscreen at boot : create a file in "/etc/X11/xorg.conf.d/" named for example "99-no-touchscreen.conf". And then add this into the file :

"

Section "InputClass"
    Identifier     "Touchscreen catchall"
    MatchIsTouchscreen "on"

    Option "Ignore" "on"
EndSection

"

I also blacklisted the corresponding module kernel (lsmod ; /etc/modprobe.d/blacklist-hid-multitouch.conf < blacklist hid_multitouch"). To be sure.

It work without any problems now.
