Comment 0 for bug 1721394

You would see -
$ nvidia-settings
** Message: PRIME: Requires offloading
** Message: PRIME: is it supported? yes

** (nvidia-settings:1848): ERROR **: PRIME error: Failed to execute child process “/usr/bin/prime-select” (No such file or directory)
Trace/breakpoint trap

Additionally if trying to run prime-select you'd see -
sudo: unable to execute /usr/bin/prime-select: No such file or directory

One would need to go
 python3 /usr/bin/prime-select intel

This is because the python package has been removed from image & is installed by either nvidia-settings or nvidia-prime.

Please adjuct this packages to either use python3 or dep to python
