I updated Linux Mint on my laptop, and the sound broke. I restarted, but now after the login screen (which displays correctly) it shows a black screen with the message:
: unable to launch “cinnamon-session-cinnamon” X session - “cinnamon-session-cinnamon” not found; falling back to default session.
I click okay and just get a black screen with a mouse cursor. I can’t use Ctrl+Alt+t to get a terminal. Ctrl+Alt+F1 and Ctrl+Alt+F2 also do nothing.
Holding the shift key during start up doesn’t open Grub.
Please help me how to proceed from here.
