As I've discussed (completely newbiely) previously here:
and here:
, I am experiencing various little problems since I've fresh installed Manjaro. A fresh, official and up to date image provided by Manjaro required 5GB updates after installation and I've experienced several minor bugs and glitches during the process.
One I couldn't fix, researching, since than, is at the log in screen (there is a proper name for that splash screen, which I can't remember right now).
It happens that I can't click anywhere on that screen. No buttons respond. When I pass the cursor by, the icons highlight, but no interaction. For me it looks like the second topic I've made (the second one on this very topic) for those problems.
Are you by any chance using a touchpad instead of a mouse and trying to use tap-to-click? It has to be enabled explictly for Xorg to work on the login screen.
Try using hardware buttons.
I forgot to mention I'm using KDE, so it might me configurable on system settings. Do you know how so?
Also, I was able to use touchpad onto the login screen before updated. Seems it also de-configured
