If anybody still has a reproducer, it would be useful to set a trace
point like this:
sudo vim /usr/bin/prime-select
# ...
import pdb
pdb.set_trace()
if profile == 'nvidia':
# Always allow enabling nvidia
# (No need to check if nvidia is available)
self._enable_nvidia()
elif profile == "on-demand":
self._disable_nvidia(keep_nvidia_modules=True)
else:
# Make sure that the installed packages support PRIME
#if not self._supports_prime():
# sys.stderr.write('Error: the installed packages do not support
PRIME\n')
# return False
self._disable_nvidia()
# ...
and see if _disable_nvidia is entered when `prime-select intel` is
invoked while `prime-select query` shows "nvidia" or "on-demand".
Before I removed the driver and the nvidia-prime package, I could switch
the profile back and forth using `prime-select intel` and `prime-select
nvidia` without any positive effect so it would be useful to find out
why.
The code only depends on the target profile specified via command line
and the current profile (read from /etc/prime-discrete) so I don't have
any guesses yet:
