KDE - Disable Netbook's Touchscreen?

English Hardware
#1

Hi,

Running openSUSE Tumbleweed KDE 64Bit on a netbook.
How would I disable the touchscreen of the netbook?
Let me know, thanks!

Never had one on a netbook but I would start with System settings>Input devices

Hi,

Don’t see any settings there to disable touchscreen.
Anyone else know?

Hi,

Tried the following in KDE terminal:

su
zypper install xinput
xinput
xinput disable [ID]

but get error below:

No protocol specified
X Error of failed request:  BadAccess (attempt to access private resource denied)
  Major opcode of failed request:  131 (XInputExtension)
  Minor opcode of failed request:  57 ()
  Serial number of failed request:  21
  Current serial number in output stream:  22

Any ideas?
Thanks!

Hi
And as your user? Are you running Xorg or Wayland session?

#6

Hi,

I don’t know…
…I am running default that KDE installs.

Hi
So run xinput as your user, run the following command as your user;


echo $XDG_SESSION_TYPE

If it’s wayland… then not sure xinput would work…

#8 
echo $XDG_SESSION_TYPE

shows:

x11

new-host:/home/jlp # xinput

xinput disable 11

Thanks!

Uggg…

Does not survive a reboot?
Any idea how to disable the touchscreen permanently?

  1. Since you’re using Xorg, you can disable globally by creating a custom .conf file under /etc/X11/xorg.conf.d/ (eg 85-touchscreen.conf)

Make sure the identifier name matches your device name from ‘xinput list’, so something like the following…

Section "InputClass"
   Identifier    "USBest Technology SiS HID Touch Controller"
   MatchIsTouchscreen   "true"
   Option    "Ignore"   "true"
EndSection

It will take effect next time that Xorg starts.

  1. Alternatively, you can disable it as a user by adding the appropriate command to KDE autostart

System Settings > Workspace > Startup and Shutdown > Autostart > ‘Add Program…’, Add the 'xinput disable 11 ’ command, and make sure to enable ‘Run in terminal’ under ‘Terminal options’. That should take effect the next time your user desktop is started.

PS Using

xinput disable "USBest Technology SiS HID Touch Controller"

may be better than the numeric ID as that may change if other input devices are added etc.

That worked perfectly, thanks!
