[Solved] Nvidia goes rtd3 only if graphical environment is shut down

On tty, after stopping gdm, cat /sys/bus/pci/devices/0000:01:00.0/power/runtime_status shows expected "suspended"

After starting gdm and switching to tty runtime_status changes to active and suspends after a while.
after logging into gnome wayland session runtime_status changes to active and remains in this state (bad).
switching ttys with gdm disabled also activates the GPU.

nvidia-smi shows "No running processes found"

$ cat /sys/class/drm/card*/device/power_state
D0
D0

nvidia-persistenced.service is enabled and running

$ cat /sys/bus/pci/devices/0000\:01\:00.0/power/control
auto

$ cat /proc/driver/nvidia/gpus/0000\:01\:00.0/power 
Runtime D3 status:          Enabled (fine-grained)
Video Memory:               Active

GPU Hardware Support:
 Video Memory Self Refresh: Supported
 Video Memory Off:          Supported

S0ix Power Management:
 Platform Support:          Supported
 Status:                    Disabled

Questions

- Are the deep sleep issues present on other DEs or with the nouveau driver?
- Is it possible to fully unload Nvidia modules when all programs are using the Intel GPU, use WM with gpu passthrough for a while, shut down the WM, then without needing to log out use Nvidia GPU?
- If there is a choice whether it is better to use aur packages or faltpacks

- Do I need to specify `compress=lzo` for each subvolume, or is it sufficient to use it only for the root (`@`)?

### /etc/fstab

UUID=14296c08-47e6-457f-8319-d5c9309c8f77	/         	btrfs     	rw,relatime,ssd,discard=async,space_cache=v2,compress=lzo,subvolid=256,subvol=/@	0 0
UUID=14296c08-47e6-457f-8319-d5c9309c8f77	/home     	btrfs     	rw,relatime,ssd,discard=async,space_cache=v2,compress=lzo,subvolid=257,subvol=/@home	0 0
UUID=14296c08-47e6-457f-8319-d5c9309c8f77	/var/log  	btrfs     	rw,relatime,ssd,discard=async,space_cache=v2,compress=lzo,subvolid=258,subvol=/@log	0 0
UUID=14296c08-47e6-457f-8319-d5c9309c8f77	/var/cache/pacman/pkg	btrfs     	rw,relatime,ssd,discard=async,space_cache=v2,compress=lzo,subvolid=259,subvol=/@pkg	0 0
UUID=F05A-1537      	/esp     	vfat      	rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro	0 2

- I use time-shift and have some btrfs backups. Is it possible to enable disk encryption at this stage without breaking existing backups or backup functionality? How would this affect file sizes?

### tlp uses default settings

GPUs:
NVIDIA GeForce RTX 3050 Laptop GPU/PCIe/SSE2
Intel(R) Graphics (ADL GT2)

at least after edit this post is readable

Re: [Solved] Nvidia goes rtd3 only if graphical environment is shut down

gnome-remote-desktop is bad, but opening programs still wake the GPU in most cases (but do not prevent gpu from "resleeping")

Re: [Solved] Nvidia goes rtd3 only if graphical environment is shut down

GSK_RENDERER=ngl in /etc/environment is fine workaround for now.
