On my Manjaro Gnome it only worked after i used /usr/lib/ instead of /usr/lib64/

@graysky Thank you very much for your work. Much appreciated.

There are a number of reported issues with the driver and 5.11 ie login managers window managers, xfwm4 and possibly other I am not aware of. The driver works fine on lts. Could it be the 5.11 patch?

(5.11 + 20-nvidia.conf) I replaced SDDM with lightdm, lightdm started, but after that the plasma session (X11-plasma) did not start - dark screen. Downgraded to linux-lts (5.10).

@leopseft SDDM does not work, for some reason. i tried lightdm, just for the sack of it and it worked. try: 'sddm --test-mode' for some output.

Like @vicpt said, let's keep this space for the NVIDIA driver, but do share if you find a way to make it work.

Downgraded to 5.10 Kernel.

With Kernel 5.11 I tried both adding the

{{ Section "Files" ModulePath "/usr/lib64/nvidia/xorg" ModulePath "/usr/lib64/xorg/modules" EndSection }}

and renaming the identifier in device section as mentioned (from Device0 to Nvidia Card) with no luck at all!

Also tried keeping only the minimal config in case that something else on the previous working config breaks but with no luck either.

I don't know if it's SDDM problem or Xorgs (I do use SDDM too) but I know for sure that previous kernel works!!

Good to know you guys figured it out.

But lets remember this thread is not for discussing display managers or window managers. The best would be a wiki entry explaining all your specific DM and WM configs and tweaks.

Let's keep this space to talk about the NVIDIA driver.

Alright is seems that sddm might be the culprit with 5.11 kernel not showing. I went and disabled sddm login manager and installed lightdm-gtk-greeter and enabled it with systemctl and rebooted to linux 5.11 and works just fine.

Update - It seems that sddm desktop manager does want to show up on 5.11 but on 5.10 it works fine. So my idea is what if i just launch plasma desktop without a desktop manager. I stopped sddm with systemctl. I made my ~/.xinitrc i type in "exec startplasma-x11" for xorg and saved and exit. I typed in "startx startplasma-x11" and boom plasma DE worked so i might have a feeling that sddm or something is the cause of the issue. I gonna have to test other login managers or desktop manager to see what up. But i finally managed to get to the desktop with 5.11 kernel.

@CourteousGeek without providing dmesg logs or Xorg logs I can't help you. @esturiano I don't use SDDM.

I don't want to spam the thread with useless messages. If you guys want I can try help. I'm on Freenode and matrix.org

@vicpt I saw your сcomments in step 15 and did everything as you suggested. But the SDDM does not start. Yours starts, but several users report that it does not.
