For some reason, Xfce (at least I assume that’s what’s doing it) periodically brings me to the LightDM screen and makes me put in a password. I went to XFCE Power Manager and in the “System” tab, set “System power saving” to “Never” and unchecked the “Lock screen when system is going to sleep” box and on the “Display” tab, I moved “Blank After” to “Never” and even unchecked the “Display power management” box. I also went to LightDM GTK+ Greeter settings and on the “Misc” tab, I moved the “Timeout until the screen blanks” slider to “Never”. It’s still happening. Even if I’m in the middle of typing a sentence (like now), it sometimes brings me to the login screen. This is my first time starting a topic. I did try to search for this issue in existing posts, but didn’t find anything. Thanks!
that is a strange issue, have you already tried to reinstall Lightdm?
The easiest way to do so is:
sudo pacman -S lightdm
