After I started up my computer, having updated the last time I used it, going past the log in screen just shows the lock-screen background for a little bit, before a black screen with just a cursor. The Lock Screen still works if I shut the laptop lid or leave the computer enough, but the screen doesn’t seem to turn off properly when shutting the lid and most keyboard shortcuts don’t work, though I can still go to tty.
I tried updating. I tried reinstalling Cinnamon. That didn’t work, but installing lxde and selecting that at login worked, but Cinnamon still doesn’t.
I eventually found out that right clicking the black screen Cinnamon desktop still works, and I can get windows such as the terminal like that, but the windows won’t move or resize.
Probably just going to do a new install.
Just got round to trying that. This is weird. When I try to login as the new user; this happens:
It just goes to a TTY screen that says
[FAILED] Failed to start casper-md5check Verify Live ISO checksums.and then returns to the login screen.Edit: That same message was shown when I pressed Shud Down, though it did successfully shut down.
That’s pretty weird. It’s a live ISO error, you shouldn’t get something like that.
It’s probably not that but if the filesystem is corrupted you can get weird things. Try this:
sudo fsck -f /If still no effect, login to LXDE and find cinnamon config files under
~/.config/cinnamon, not sure about the exact location since I don’t use Cinnamon but should be something like that. After finding that, change the name to cinnamon.bak and try login to Cinnamon again. If that’s related to configs, you should be able login.You can also try different display manager, it seems you currently have lightdm. For instance, sddm could be an alternative.
sudo apt install sddm sudo systemctl stop lightdm sudo systemctl disable lightdm sudo systemctl enable sddmthen restart.
If you want to revert this, just
sudo systemctl disable sddmandsudo systemctl enable lightdm. You can remove sddm after the experiment.
