I’m having an issue in linux mint 22.3 cinnamon where the GUI locks up but audio still plays and the mouse cursor still moves. The solution is to press ctrl+alt+f1 to take me to a terminal and then press ctrl+alt+f7 to go back to the GUI. Then everything works fine. Forgive me, I do not know what to call the terminal when accessing ctrl+alt+f1 other than tty1.
I also have an issue where when using a browser (librewolf / waterfox / zen) and using the pop out video window, sometimes over time it will lock in the main browser window and the solution is to minimise and restore the window. Sounds related.
I am new to linux and not sure where to start. I think there is something up with the cinnamon desktop environment but I do not know what. Hardware has been stress tested, multiple components, multiple days. I think it is a software issue but could be wrong, that is why I am asking for help.
Any help / thoughts much appreciated.
Thank you.


Could you please explain a little more on what X11 and wayland are? My current level of understanding is just that I am running the cinnamon desktop environment. How can I find out the information you are looking for? Also, why is it that going into ctrl+alt+f1 and then ctrl+alt+f7 to go back, resolve the issue? Thanks for your reply.
