The touchpad can be disabled easily with xinput or kde-config-touchpad.
The touchpad LED /sys/class/leds/dell-laptop::touchpad/brightness needs to be set to “1” when the touchpad is disabled and this is not done by default.
The touchpad LED can be fixed as follows:
1. Make a copy of /etc/acpi/asus-touchpad.sh and call it /etc/acpi/dell-touchpad.sh
2. Edit the file and replace this line:
ledf=/sys/class/leds/asus::touchpad/brightness
with this line:
ledf=/sys/class/leds/dell-laptop::touchpad/brightness
3. Executing sudo /etc/acpi/dell-touchpad.sh will now enable/disable the touchpad and toggle the LED correctly.
To avoid being prompted for a password:
1. Make /etc/acpi/dell-touchpad.sh read-only:
sudo chmod -w /etc/acpi/dell-touchpad.sh
2. Edit sudoers to allow sudoers to execute without password prompt.
myusername ALL = (root) NOPASSWD: /etc/acpi/dell-touchpad.sh
Finally, bind the exectuion of /etc/acpi/dell-touchpad.sh to the XF86TouchpadToggle keyboard event using xbindkeys.
~/.xbindkeysrc
#Disable Touchpad "sudo /etc/acpi/dell-touchpad.sh" m:0x0 + c:199 XF86TouchpadToggle
Then make sure you add xbindkeys to ~/.xinitrc to make sure xbindkeys starts with your desktop environment.
Was a pain-free install of Debian. No issues. Use a fixed ethernet connection to install so you can grab updates & enable wireless via “apt-get install firmware-brcm80211”. I haven't tested connecting an external monitor via VGA or HDMI so not sure how Xorg will respond to this.
Would recommend this laptop for Linux. Second time I've used a Dell laptop and both have been great.
