Linux Mint,任务栏和菜单未显示? [关闭]

I am running Linux Mint 19.3 Cinnamon. I have been running with the lightdm interface for the last two weeks without issue, however this morning when I booted with lightdm it was stuck on the login screen and would not recognize keyboard or mouse input. I went through the process of:

  1. installing mdm, switching the interface from lightdm to mdm, and verifying mdm loads with no issues
  2. uninstalling and reinstalling lightdm, making sure to set the \etc\lightdm\lightdm.conf file to:
  1. Running apt install xserver-xorg-input-all

Then rebooting using lightdm I can now login, with the keyboard and mouse input recognized.
