Hey,

I have an Lenovo P52s and KDE and getting this Errors when trying to suspend.

Is there a fix for that?
Thank you in advance :slight_smile:

just two questions, as I might have encountered a similar situation in the past:
a. do you have a etc/modprobe.d/nvidia.conf, and if positive, what’s the content of it?
b. I do not know the laptop you have, is it a dual-gpu or there’s just the nvidia?

thanks, and welcome to Endeavour :enos:

Thanks for your answer:

options nvidia-drm modeset=1
options nvidia NVreg_PreserveVideoMemoryAllocations=1
  1. It has a dual gpu: intel and nvidia

ok, I redirect to a similar issue I’ve found on Arch forum (hope it’s ok for Endeavourists)…the guy solved by deleting the lines in nvidia.conf (in your case just the NVreg_PreserveVideoMemoryAllocations) and rebooting.
If you want to try with that, naturally I suggest to backup that file before…

Moreover you can enable the drm modeset via kernel options in your initramfs, hence having it early loading (just double check, being a dual-gpu)
On the other hand, the options nvidia NVreg_PreserveVideoMemoryAllocations=1 might deal exactly with suspension/hibernation as per archwiki…and indeed, while my situation was different as I didn’t have to deal with a dual-gpu, from your logs it seems the nvidia card fails to suspend, so I think also about the services coming with the official drivers that might be called in the process and being disabled…but being this one a rough terrain for me (see another recent post dealing with nvidia and gdm suspension), I’d invite you to wait for someone else to chime in and confirm it before starting to enable those services :wink:

Thanks, that helped.
The NVreg_PreserveVideoMemoryAllocations was the problem. Removing it and everything works fine!
