I recently used sudo Pacman -Syu firefox to update my system and install Firefox , but after the system update the font on my system kinda glitched so rebooted my laptop . Now i am stuck at login screen loop , so i opened the tty and entered the startx command. startx returns an error.
Being stuck at the login screen and your need to open a tty is indicating you are already at the GUI login screen…
Which means you should not try to start X again…
Asking wrongly worded questions results in wrong assistance…
At the login screen press Ctrl+Alt+F2. Then at the login prompt type your usename. The password shows next, so type your password. If both were correct your home account prompt will follow.
Type df, and check that your root partition is not full, and if you have a separate home partition, that is not full either.
