Linux lite freezes randomly

[Moltke]

I tried ctrl+alt+f3 can't figure out which login information I am supposed to type.

Linux offers the posibility to switch between GUI mode, for example in LL the GUI is XFCE desktop, which you log in to every time you start LL, and a tty, which you can access by holding Ctrl+Alt+Fn usually F7 is reserved for the desktop so you can use the rest; F1, F2 ... to start a tty session. You should get a login prompt where you input you username and passsword, the same ones you use when logging to the GUI. This is useful to debug issues like when in your case, the GUI freezes and/or become unresponsive. What can you do once in a tty? Well, that depends on the kind of issue you're facing, in your case you might want to check X logs, to do that type at the console:

Code:

less /var/log/Xorg.0.log

read the file and look for any error messages that might be related to your issue. You can also restart your pc by typing

Code:

sudo systemctl restart

type in your password when asked and hit enter. Read here for a little more info on ttys https://unix.stackexchange.com/questions...and-a-con/  and here for some tips on how to troubleshoot a GUI freeze https://www.fosslinux.com/39434/5-things...reezes.htm
