As a part of my home network setup, I use an old Dell Studio XPS 15″ laptop as my “server.” It’s currently running Ubuntu 19.10. One issue I had during the last update was that whatever I set up a long time ago to manage the lid switch policy was lost, so I had to re-google it and re-do it, because I don’t want the screen to be on 24/7.
Some Googling led me to a post that got me part of the way there:
I had to adjust a few things for my setup, and for posterity I’m going to log them here for the future.
# As root, or sudo'd apt install vbetool -y echo 'event=button/lid.*' | tee --append /etc/acpi/events/lm_lid echo 'action=/etc/acpi/lid.sh' | tee --append /etc/acpi/events/lm_lid touch /etc/acpi/lid.sh chmod +x /etc/acpi/lid.sh
This will set everything up for the
lid.sh script to run:
#!/bin/bash # Close grep -q close /proc/acpi/button/lid/*/state if [ $? = 0 ]; then sleep 1 && vbetool dpms off fi # Open grep -q open /proc/acpi/button/lid/*/state if [ $? = 0 ]; then sleep 1 && vbetool dpms on fi
Finally, reboot and enjoy not having to worry about the screen dying.
