Bug#1058081: nvidia-graphics-drivers: Include systemd power management services and scripts

[Jian-Hong Pan]

Package: nvidia-graphics-drivers
Version: 530.41.03-3

Hi,

I follow the discussion of "nvidia-graphics-drivers: please package
systemd power management scripts" [1] and
* Install new package nvidia-suspend-common: So, there are the systemd
unit files and "nvidia-sleep.sh"
* Set NVreg_PreserveVideoMemoryAllocations: So, nvidia's parameter
"InitializeSystemMemoryAllocations" is 1
$ grep InitializeSystemMemoryAllocations /proc/driver/nvidia/params
InitializeSystemMemoryAllocations: 1

Also, took Fedora's gdm patch "udev: Stick with wayland on hybrid
nvidia with vendor driver" [2]

Then, the system uses GNOME Wayland!

$ printenv XDG_SESSION_TYPE
wayland

However, system fails to suspend and shows the error in log:

systemd-sleep[2781]: /usr/bin/nvidia-sleep.sh: line 33: chvt: command not found
systemd-sleep[2794]: /dev/sda:
systemd-sleep[2794]:  setting Advanced Power Management level to 0xfe (254)
systemd-sleep[2794]:  APM_level        = 254
systemd[1]: systemd-suspend.service: Main process exited, code=exited,
status=1/FAILURE
systemd[1]: systemd-suspend.service: Failed with result 'exit-code'.
systemd[1]: Failed to start System Suspend.
systemd[1]: Dependency failed for Suspend.
systemd[1]: suspend.target: Job suspend.target/start failed with
result 'dependency'.
systemd[1]: Stopped target Sleep.
systemd-logind[459]: Operation 'sleep' finished

The "chvt" should be provided by kbd package.
After I install kbd, the system can suspend & resume correctly.

I think kbd should be the dependency of nvidia-suspend-common.
