Problems with nvidia-xrun

Hi all!
I have some troubles with "nvidia-xrun" script.
I was install it from AUR, last version, nvidia-drivers is last version, also like bumblebee and bbswitch.
About problem: when i try to go to another tty, then kill X-server and progs, than type nvidia-xrun in console, all works.
But when i want to log out and go to my integrate graphic card, i have errors whith modules unloading.
nvidia-xrun runs openbox-session.
What i am doing wrong?

When I logout from openbox-session (right button-> logout) i see this errors:

Unloading nvidia_drm module
rmmod: ERROR: Module nvidia_drm is in use
Unloading nvidia_modeset module
rmmod: ERROR: Module nvidia_modeset is in use by: nvidia_drm
Unloading nvidia module
rmmod: ERROR: Module nvidia is in use by: nvidia_modeset
Turning off nvidia GPU

Current state of nvidia GPU: 0000:01:00.0 ON

using #tee /proc/acpi/bbswitch <<<OFF don't work, discrete card working. Only reboot can helps

Re: Problems with nvidia-xrun

This is quite a common thing. I get a simmilar issue with nvidia-xrun and xfce. Basically something continues to use the nvidia_drm module, blocking its removal

You can have a look at the following bug report.
https://github.com/Witko/nvidia-xrun/issues/32

I wasn't entirely convinced that stopping and restarting systemd-logind was the best of ideas, especially if you have a display manager still open on another tty. Plus by the time you've done that and manually removed the modules and stopped the card, you may as well have done a reboot and 'fixed' it that way anyway.
