i have two problems that are very important for me. Today I had the idea to play with the different desktop environments, but now I have trouble with my system. I have a system that runs XFCE. That was fine but of course I was curious and I tried GNOME. After that I removed it with
sudo pacman -Rcn gnome. After that everything went wrong.
I had to install xfce4 and the xfce4-goodies again because everything was removed. Since then my keyboard keys do not work anymore (like sound and brightness). The brightness change all the time. And when I reboot I am not able to log-in using lightdm, but using the terminal and then start xfce with
I would like that my system works like it should. Another problem is that when I do a system update (
sudo pacman -syu) all the output stays at 0%.
When I try to reinstall lightdm it gives the error that the files are already in the filesystem.
When I try
systemctl enable lightdm.service it says it is masked and even after unmasking it it says it is still masked.
Can somebody help me so my system is the same as yesterday when everything worked?
Thank you for your help and time!
