Wayland session is giving me a black screen

[doug]

After updating Manjaro KDE a few days ago (Dec 4th or 5th), the Wayland session is giving me a black screen- I can bring up a terminal, but couldn’t start Firefox. X11 session is fine. Rolled back to the most recent BTRFS snapshot and everything is fine. Updated again but the problem reoccurred.

Nvidia drivers? If so, last days I suffered an issue like yours:

Help testing Nvidia drivers with Kernel 6.12

I was using kernel 6.12, Wayland and Nouveau drivers on a Nvidia GT710 and had no problems. Yesterday switched to Nvidia 470 and Wayland stopped working. The login screen appears, once logged there’s only the background image and the cursor. No menu, no panels, no desktop icons. Right clicking the mouse appears the context menu. I can create a folder in the desktop or go to screen properties where there’s another screen I don’t have: [20241206_092741] After today update (including Nvidia 470…

Can you run inxi -Gxx in a terminal and see if a second monitor appears?

No Nvidia, my GPU is AMD.

Here’s the output from inxi:

DP-1 would be my external monitor.

@doug please use 3 ticks ``` to surround any CLI output, or the </> button in the menu.

I’ve fixed it for you so that others can read it.

[doug]

Thank you, my apologies!
