Greysceen on resume from suspend With Gnome48 Wayland & HDR

[jjis]

Apologies for bring this up as I know resume from suspend seems to be a perennial on and off problem. Had hoped that recent Nvidia driver updates might have solved this but the recent update of GNOME 48 seems to have introduced this new problem.

I think this is because this now allows me to use the HDR capabilities of my screen, which I was not able to do before. I am assuming it is related to GNOME 48 and HDR as it doesn’t seem to happen if HDR is not selected. Main work around I have found is to either not suspend the machine or try and remember to switch off HDR in the settings before suspend. Has anyone else come across this or got any suggestions? inxi -SGaz below anything else I might need to show? Thanks in advance.

@jjis Hi have you activated any mutter experimental features either via gsettings or dconf-editor?

You should also add fbdev=1 nvidia_drm.modeset=1 to you boot options

[jjis]

Thanks for the suggestions, I will have a look at those tomorrow & report back.

[jjis]

Morning Malcom, I tried adding the fbdev=1 nvidia_drm.modeset=1 to my boot options but the same grey screen issue persisted. See screenshot. Although it also flickers a bit between grey and trying to go to blacker HDR I guess so not sure what’s going on. I think it is probably more or a Gnome / Wayland thing rather than Opensuse. As far as I’m aware I haven’t activated "…any mutter experimental features either via gsettings or dconf-editor? Not sure where or how to access those or how to check if I have.

[malcolmlewis]

@jjis I suggest looking at org.gnome.mutter experimental-features in dconf-editor. See how kms-modifiers goes, maybe scale-monitor-framebuffer as well.

Thanks Malcom, I tired those but the problem still persists. I think I’ll just stick with either shutting down instead of suspending or manually switching off HDR in the screen settings before suspend as it seems to resume OK without HDR enabled.
