--- Comment #3 from [email protected] --- After boot, I need to unbind the nvidia driver from the secondary gpu and bind VFIO drivers to it for use in a virtual machine with gpu passthrough. The kwin_wayland process holding the secondary gpu prevents the nvidia driver from successfully unbinding. In 6.6, there was no issues doing that. A workaround I've found in the meantime is to launch my unbind nvidia driver script, which stalls at this line (echo "0000:05:00.0" > "/sys/bus/pci/devices/0000:05:00.0/driver/unbind") because a process is running on the gpu, log out (shutting down kwin in the process), then log back in. After that, kwin doesn't get a hold of the secondary gpu (I assume because the unbind command went through after kwin was shut down), and I can bind/unbind nvidia/VFIO drivers on my secondary gpu. -- You are receiving this mail because: You are watching all bug changes.
