Nvidia 555.52.04 Plasma 6.1 Wayland - Screen turn off on login

Graphics / Linux Linux

Hello,

After upgrading to KDE Plasma 6.1, when I login a Wayland session the screen turns off after showing “No Signal”. This doesn’t happen on a GNOME Wayland session. When the screen turns off I can’t switch to a terminal either. I can login on a Plasma X11 session just fine.

Before upgrading I was using Plasma 6.0.5 with the same driver (Nvidia 555.52.04) without issues except a Kwin crash on resume from suspend.

Specs and infos:

  • Up to date ArchLinux with linux-zen
  • KDE
  • Driver 555.52.04 from AUR
  • Nvidia RTX 4060 (ASUS Dual GeForce RTX 4060 OC Edition 8GB)
  • Desktop system with Intel 8600K
  • GRUB_CMDLINE_LINUX_DEFAULT=“loglevel=3 resume=UUID=4461aafb-f9f2-431d-b01e-948248922a3f tsc=reliable quiet splash nvidia-drm.modeset=1”
  • /etc/modprobe.d/nvidia.conf => options nvidia-drm modeset=1 fbdev=1
  • /etc/environment => (I removed comments and unrelated stuff)

GBM_BACKEND=nvidia-drm
__GLX_VENDOR_LIBRARY_NAME=nvidia
__GL_SHADER_DISK_CACHE_SKIP_CLEANUP=1

  • /etc/mkinitcpio.conf => (I removed comments)

MODULES=“nvidia nvidia_modeset nvidia_uvm nvidia_drm”
BINARIES=“”
FILES=“”
HOOKS=“base udev autodetect modconf block keyboard keymap resume filesystems fsck”

  • /etc/X11/xorg.conf.d/20-nvidia.conf => (No very relevant for Wayland but just so I include everything)

Section “Device”
Identifier “Nvidia Card”
Driver “nvidia”
Option “PrimaryGPU” “on”
Option “Coolbits” “26”
EndSection

The report was done on X11 since I can’t login on Wayland at all.

EDIT: I tried with nvidia.NVreg_EnableGpuFirmware=0 on the command line params and also tried with regular kernel instead of zen but it didn’t help.
EDIT 2: Reworded and I tested GNOME Wayland and it works fine.

I reported it to KDE as well now since the issue might be there since it works fine with GNOME Wayland and it worked fine with Plasma 6.0.5: 488941 – Plasma 6.1 Screen turn off on login into a Wayland session

Does it go away if you disable VRR? If you can’t get to systemsettings you could set the vrrPolicy value to Never in ~/.config/kwinoutputconfig.json

Thank you very much for the suggestion. Changing the vrrPolicy didn’t help but deleting the file did. After that I investigated a little and it seems the issue is related to HDR, because if I enable it and reboot the issue come back.

The difference between the config that works and the one that doesn’t work it “highDynamicRange” and “wideColorGamut” are both false on the config that works and “true” on the config that doesn’t work.

Also getting this same behavior on Arch since KDE updated to 6.1 in the extra repo.

Details on the KDE bug HERE and HERE.

No issues on KDE 6.0 prior to the package update.
