[SOLVED]Arch PC does not sleep properly

My arch linux PC with a 3090 FE running  non noveau drivers 595.71.05, the kernel 7.0.5-zen1-1-zen, an i7-13700K, and 64GB DDR5 6000 is unable to sleep properly. When I attempt to sleep the fans slow down, the screen goes black, but then the fans ramp back up to normal while the screen remains black and the system is unresponsive to anything except a force shutdown via PSU or 10second power button hold. I have confirmed preserve video memory allocations is on via sort /proc/driver/nvidia/params. Secure boot is fully disabled in the UEFI. Is this just a compatibility issue with all nvidia gpus and can I fix it? Thanks

Re: [SOLVED]Arch PC does not sleep properly

I followed the instructions in the guide and confirmed that I successfully turned off the GSP as well as turned on  preserve videomemoryallocations. I ran systemctl suspend and nothing happened except the screen went black the fans revved and my peripherals RGB turned off Ctrl Alt F2 didnt work I had to forceshutdown

Re: [SOLVED]Arch PC does not sleep properly

Well I now feel stupid. Apparently  /sys/power/mem_sleep was set to s3 which my motherboard does not support and all I had to do was set s2idle
