Stuck on TTY, how to erase/rest Linux?

[carmine fractal]

there are a few things we can do to fix this before we resort to reinstall it

can I get the output of sudo dmesg

could you try sudo systemctl restart --now lightdm?

you have extra characters before sudo

should only be sudo systemctl restart --now lightdm

ctrl + C

then re type

you have, right here

can you log in and see your desktop?

perhaps you could, try rebooting again if it does not work you can resort to reinstall

before that might what to try changing desktop enviroment, see that you have a nvidia card.
get to the login screen again and change to wayland or software render.

yes you can

Ctrl + Alt + F1-f6 should open the terminal again

on the login, the little icon at the top right of the login prompt window

hold on let me send you a screen

[carmine fractal]

no on the cinnamon logo right at your password entry

the mountain looking logo

just to the right of the name

click esc

so the "login" bar is not "active"

[carmine fractal]

i think you borked cinnamon, can you go into a tty again and do sudo apt list --installed cinnamon

no output means you uninstalled it or got removed

so you removed the cinnamon package?

Run

lsmod | grep nvidia

yea you got one right, but no output so no nvidia driver

So most probably Secure Boot and then a reinstall won't help.

oh yea no problem. but you got to go into your bios and disable secureboot, then it might "magically" start working, but probably you have to reinstall the nvidia driver

you don't need windows, throw it in the bin.
i was just looking for the manual page:
https://mintguide.miraheze.org/wiki/Installing_Linux_Mint/Secure_Boot

it's part of the whole guide for getting ready, https://mintguide.miraheze.org/wiki/Installing_Linux_Mint so on HP bios should be the F10 key

ok, hammer that F10 button like it ows you money

hmm, do you have an exact model number for your computer?

ok it might be ESC then to get into like a "startup menu" then F10 to get into bios

yea F10

yes ok. well what you are looking for is to get in and find the secure boot flag and turn it off, should look something like the picture.

here are the troubleshooting steps i found for the keyboard, something should get you there.

1. If the keyboard doesn’t work, plug in a wired USB keyboard.
2. Try different USB ports, preferably a USB 2.0 port if available.
3. If still no input, disconnect all USB devices except the keyboard.
4. Power off, then hold Windows key + B, then press Power to trigger HP’s firmware recovery; release when the screen changes. This sometimes reinitializes keyboard input in BIOS.

disable that sucker

nice now you save and exit

probably now you are gonna have to take one more trip into the TTY.

and run

sudo apt update
sudo apt install nvidia-driver-535
sudo reboot

535 is stable driver and for your vintage should work, after that reboot we hope you can log in and have everything work.

na but if you can login that's fine

when secure boot was disabled the computer could "see" the GPU again, and has a driver now

should just be able to run nvidia-smi in the terminal and see your card

ok, no harm at all.
