[~Solved][Kde] works but [Hyprland] gives black screen.

- Kde [x11] works well, kde[wayland] starts but gets extremely buggy and unusable, launching Hyprland gives black screen and back to sddm.

GT740 - 12th gen CPU

Hyprland log:
Log tail:
[WARN] Your GPU does not support GL_EXT_read_format_bgra, this may cause issues with texture importing
[LOG] EGL: GPU Supports Format AB24 (0x34324241)

Hyprland.conf:
env = XCURSOR_SIZE,24
env = HYPRCURSOR_SIZE,24
env = LIBVA_DRIVER_NAME,nvidia
env = XDG_SESSION_TYPE,wayland
env = GBM_BACKEND,nvidia-drm
env = XDG_RUNTIME_DIR,/tmp/

cat /sys/module/nvidia_drm/parameters/fbdev  --->  No such file or directory

cat /sys/module/nvidia_drm/parameters/modeset  ---> Y

Grub:
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet ibt=off nvidia_drm.modeset=1 nvidia_drm.fbdev=1"

tail /etc/modules-load.d/*.conf --->  #tls

nvidia-smi ---> NVIDIA-SMI 470.256.02 | CUDA Version: 11.4

modprobe -c | grep -v alias | grep nvidia:

options nvidia_drm fbdev=1

470xx drivers lack most of the improvements that make wayland on nvidia actually relevant and possible. the fbdev parameter does absolutely nothing for that driver since it doesn't exist there. You either have to opt for nouveau or no Wayland on this system.

Generally speaking, pairing a 2 year old CPU with a 10+ year old budget low level GPU seems like a weird choice. Get yourself anything remotely more modern and you will vastly outperform that GPU and have less driver woes.

makes sense.  I thought i was missing something, i'll give a try with a 970.

Thanks for replying!

That's not that much of an upgrade, but you'll be able to use the current driver and thus all relevant developments for wayland support indeed.

I see, i don't know if i can make others like i3, qtile, even sway? work with x11, while i don't have a newer gpu.

With a 970 these should work fine, as a 970 can use the latest driver still. Sway is Wayland so "with X11" makes no sense in that context, but yes you should be able to use the current prop driver versions if you want Wayland support (significant betterment with xwayland is expected for the 555 series currently available as a beta driver)

If you consider it so, yes, by editing the title in your first post.
