I have a touchscreen, but the drivers are not working properly and interfere with my mouse.

Is it possible to disable my touchscreen , so that I can work again properly?

You can try disabling the input device with the xinput command. First see what input devices you have, just type:

xinput

And you should see a list like:

$ xinput 
⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]
⎜   ↳ Atmel Atmel maXTouch Digitizer            id=9    [slave  pointer  (2)]
⎜   ↳ TPPS/2 IBM TrackPoint                     id=13   [slave  pointer  (2)]
⎜   ↳ SynPS/2 Synaptics TouchPad                id=12   [slave  pointer  (2)]
...

Then you can disable the input device you want with this command:

xinput disable 9

Where 9 is the id of the device you want to disable. You can also use the device name between quotes.

In xinput version 1.5.99.1 , you need to do xinput set-prop 9 'Device Enabled' 0 instead. Oddly on xinput v1.6.2 the first way work.

The xinput solution did not work for me. I instead followed the instructions in this thread. This will disable it at boot time.

Edit /usr/share/X11/xorg.conf.d/10-evdev.conf
Add Option "Ignore" "on" to the end of the section with the touchscreen identifier
Reboot

For the record (Google), I have a Samsung Series 7 and my touch screen was listed as ELAN Touchscreen in xinput.
JFTR too, in this question says the power consumption difference is mostly negligible.

Edit file the file with

sudo nano /usr/share/X11/xorg.conf.d/10-evdev.conf

Change MatchIsTouchscreen from "on" to "off" in the Touchscreen section so it looks like this:

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

Save, Name and Exit

Touchscreen is disabled and no longer detected in xinput list.

In order to disable the touchscreen on Ubuntu 19.x and 20.x you can:

Wait the login screen
Press Alt+F2
Edit the "libinput" configuration and disable the touchscreen section, like that:

sudo nano /usr/share/X11/xorg.conf.d/40-libinput.conf

# Match on all types of devices but joysticks
#
# If you want to configure your devices, do not copy this file.
# Instead, use a config snippet that contains something like this:
#
# Section "InputClass"
#   Identifier "something or other"
#   MatchDriver "libinput"
#
#   MatchIsTouchpad "on"
#   ... other Match directives ...
#   Option "someoption" "value"
# EndSection
#
# This applies the option any libinput device also matched by the other
# directives. See the xorg.conf(5) man page for more info on
# matching devices.
Section "InputClass"
        Identifier "libinput pointer catchall"
        MatchIsPointer "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection
Section "InputClass"
        Identifier "libinput keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection
Section "InputClass"
        Identifier "libinput touchpad catchall"
        MatchIsTouchpad "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection
#Section "InputClass"                               <----
Identifier "libinput touchscreen catchall" <---- this one
MatchIsTouchscreen "on"                    <---- put # in
MatchDevicePath "/dev/input/event*"        <---- front of
Driver "libinput"                          <---- every line
#EndSection                                         <----
Section "InputClass"
        Identifier "libinput tablet catchall"
        MatchIsTablet "on"
        MatchDevicePath "/dev/input/event*"
        Driver "libinput"
EndSection

My "Dell Inspiron" touchscreen was broken. The cursor moved all over the place and click in random places several times a second. I was unable even to make login on the gnome or even to access the bios.

As id for xinput changes on reboot, I added a simple one-line screen on session load:

#!/bin/bash
xinput --list | awk '/Atmel Atmel maXTouch Digitizer/ {print $7}' | awk '{split($0,a,"="); print a[2]}' | xargs xinput disable

My device's name is "Atmel Atmel maXTouch Digitizer", change that with your device (use xinput --list for device name).

As @romaia's answer here shows, xinput is indeed the right way to do it.

However, I like to write a script and attach calling this script to a Ctrl + Alt + P keyboard shortcut, to make this super easy. Now I get an auto-closing window like this when I use this shortcut the first time:

...and if I use the shortcut again:

Ah, beautiful! Now I can easily enable/disable my touchpad or touchscreen, and fix mouse scroll speed, all with a single easy-to-use keyboard shortcut!

In order to disable the touchscreen on Ubuntu (Xorg or Xwayland) you can:

Wait the login screen;
Press Alt+F3 to open a console;
Find the correct device id
Edit /etc/rc.local to disable the touchscreen device;
Make /etc/rc.local executable and reboot.

$ cd /sys/bus/hid/drivers/hid-multitouch
$ ls -1
  0003:2A94:5241.0006         <- my touchscreen
  0018:06CB:7621.0001         <- my touchpad
  bind
  (...)

then, test it:

$ sudo bash
$ cd /sys/bus/hid/drivers/hid-multitouch
$ echo "0003:2A94:5241.0006" > unbind
$ killall -9 Xorg

Setup rc.local to disable it on startup:

$ sudo nano /etc/rc.local
  #!/bin/sh
  ls -1 /sys/bus/hid/drivers/hid-multitouch | grep 0003:2A94:5241 > /sys/bus/hid/drivers/hid-multitouch/unbind
$ sudo chmod +x /etc.rc.local
$ reboot

I did this way because:

It doesn’t break my other multitouch devices;
It is simpler and works on Xorg and Xwayland;
The last 4 digits of the device change often on boot, therefore, I needed a solution that locate the correct device based on a simple rule;
My Dell Inspiron 5557 touchscreen is broken in such a way that I can’t access the bios or use a graphics environment, therefore, I needed a console solution.

If your touchscreen is a touch panel screen like a USB monitor, you can add default kernel driver usbtouchscreen into modprobe's blacklist file (/etc/modprobe.d/blacklist.conf) and use your custom driver such as touchkit or evtouch.
