Aware of the nightmare that arch can be for average linux users, I've firstly installed Timeshift in order to restore the system, in case it breaks.
Using the the lastest kde image version available on manjaro webpage, I'm not able to install updates in my system. If so, the system stops responding to clicks.
I've been trying to update it through the command
sudo pacman -Syu
If I do so, I'm not able to use the system. I am no able to click anywhere. Even now after timeshift, I'm not able to click on Login on login screen. Beside that, I'm able to use the system.
What can be causing the problem?
