Where is /usr/bin/start-nvidia-persistenced ?

mettacrawler

Hi,

I get error messages:

$ journalctl -b -0 | grep start-
Jul 05 16:01:50 elbereth [567]: failed to execute '/usr/bin/start-nvidia-persistenced' '/usr/bin/start-nvidia-persistenced': No such file or directory
Jul 05 16:01:50 elbereth systemd-udevd[542]: Process '/usr/bin/start-nvidia-persistenced' failed with exit code 2.
[...repeats...]

The package nvidia-340-glx-driver-common has file /usr/lib64/udev/rules.d/71-nvidia.rules
The file /usr/lib64/udev/rules.d/71-nvidia.rules has

# Start and stop nvidia-persistenced on power on and power off
ACTION=="add" DEVPATH=="/bus/acpi/drivers/NVIDIA ACPI Video Driver" SUBSYSTEM=="drivers" RUN+="/usr/bin/start-nvidia-persistenced"
ACTION=="remove" DEVPATH=="/bus/acpi/drivers/NVIDIA ACPI Video Driver" SUBSYSTEM=="drivers" RUN+="/usr/bin/stop-nvidia-persistenced"

The package nvidia-340-glx-driver-common has /usr/bin/nvidia-persistenced and /usr/lib/systemd/system/nvidia-persistenced.service.

Please share where I can find /usr/bin/start-nvidia-persistenced.

Thanks

mettacrawler I think the udev rule might be wrong as the file does not exists (anymore).
As a test try updating the file /usr/lib64//udev/rules.d/71-nvidia.rules and replace the Start and stop sections with the below ones

# Start and stop nvidia-persistenced on power on and power off
# respectively
ACTION=="add" DEVPATH=="/bus/acpi/drivers/NVIDIA ACPI Video Driver" SUBSYSTEM=="drivers" RUN+="/bin/systemctl start --no-block nvidia-persistenced.service"
ACTION=="remove" DEVPATH=="/bus/acpi/drivers/NVIDIA ACPI Video Driver" SUBSYSTEM=="drivers" RUN+="/bin/systemctl stop --no-block nvidia-persistenced"

# Start and stop nvidia-persistenced when loading and unloading
# the driver
ACTION=="add" DEVPATH=="/module/nvidia" SUBSYSTEM=="module" RUN+="/bin/systemctl start --no-block nvidia-persistenced.service"
ACTION=="remove" DEVPATH=="/module/nvidia" SUBSYSTEM=="module" RUN+="/bin/systemctl stop --no-block nvidia-persistenced"

kyrios I applied the changes to 71-nvidia.rules and rebooted. The nvidia-persistenced started at boot and continues to run.

Package nvidia-340-glx-driver-common has file /usr/lib64/tmpfiles.d/nvidia-340-glx-driver.conf

$ journalctl -b -0 | grep persist | head -n 1
Jul 06 14:48:23 elbereth systemd-tmpfiles[514]: [/usr/lib64/tmpfiles.d/nvidia-340-glx-driver.conf:1] Line references path below legacy directory /var/run/, updating /var/run/nvidia-persistenced → /run/nvidia-persistenced; please update the tmpfiles.d/ drop-in file accordingly.

Harmless I know.

I opened this bug report https://dev.getsol.us/T8124

Thanks for the detailed report! I've commited a fix with your and kyrios' changes here
In fact, the tmpfiles.d change can be applied to all or most our Nvidia driver packages. I will do so soon.
