Prime-select intel not shutting off nvidia GPU
Solution 1:
See answer here https://unix.stackexchange.com/a/420273. Once you have switched into Intel mode you can do the command
sudo tee /proc/acpi/bbswitch <<<OFF
to turn off the GPU. Likewise to turn it back on again you can do
sudo tee /proc/acpi/bbswitch <<<ON
Preferabbly I would like this to automatically run during Intel mode instead of manually entering it after every boot. If anyone has a suggestion for how to do this it would be much appreciated.
