My Linux desktop runs parallel Windows 7. I found some solutions to fix errors, examples: restart computer, or re-install Cinnamon (sudo apt-get install --reinstall cinnamon cinnamon-screensaver cinnamon-session cinnamon-session-common cinnamon-settings-daemon libcinnamon-control-center1 libcinnamon-menu-3-0 mint-meta-cinnamon),... but not working.

What do I have to do? Is there any solutions that do not recovery system or I do not need to delete all data?

If you want to know anything, do not hesitate to ask me. Thank you so much.

Comment:- You may soon get a future problem - You are (probably) using too much space in / size: 28G used: 25G (94%) - it is likely that you have an excessive number of kernels installed.

You have not lost any data and you do not need to reinstall Cinnamon. I would expect that it comes down to your video card.

Even when Cinnamon has crashed, your computer is still running.
