nvidia card remains ON after stopping primusrun

[nikonikolov]

When I start an application with primusrun and then close it, the nvidia card remains ON. This is evident from the shortened battery life and from the fact that cat /proc/acpi/bbswitch prints ON. Tried manually unloading the nvidia module but even with --force option the system does not allow me and says it's in use. I also tried using bbswitch but bash says that this command is not found, although I installed the package. What configurations should I perform to make the nvidia card switch off automatically after the process that uses primusrun is terminated? I am using the proprietary nvidia drivers.

Have you tried the recommended way of turning OFF the card with bbswitch?

[nikonikolov]

yes. after the tee command the cat /proc/acpi/bbswitch still prints 0000:01:00.0 ON. Actually I just found out that the nvidia card starts when bumblebeed is started, no need to run primusrun to turn it on. Isn't there an automated way that will switch it on only when primusrun is using it?

[nikonikolov]

Sorry, my mistake, one of the nvidia modules was still loaded so that's why it could not switch off. Now I can switch it off manually. Anyway, how can I automate the behaviour?

Writing a shell wrapper for primusrun that turns on the card would be somewhere to start ... glad to hear your other issue was fixed!

Thanks. Just a final question https://github.com/Bumblebee-Project/bbswitch#enable-card-on-shutdown - I am struggling to find out which will be the equivalent path for this file on Slackware?

@nikonikolov, I'm not sure, try this command:

find /etc -name bbswitch.conf
