I’m trying to set up plasma bigscreen on an arch x64 installation. I grabbed plasma-bigscreen-git from the AUR, which builds from latest sources.
When I start a plasma-bigscreen-wayland session, it first appears to work correctly (showing the kde loading screen with the spinning gear). But then I only see a grey screen with a cursor on it.
I can move the cursor, and the top left corner shows the typical “active corner” highlight, but no interaction is possible. Neither click nor right click anywhere does something.
If I wait a few minutes the lock screen turns on, showing a background image and the time and date.
I tried Wayland and X11 with the same result.
How can I debug this setup? I tried to find logs somewhere, but was unsure where to look.
