Solid underscore after GRUB menu

#1 Post by fredericm »

Hello,

I have a ThinkPad T470 with dual boot Win10 and Debian 12.
I tried to run a update and I think I turned it off during the update...
Now I have GRUB, I select "Debian Gnu/Linux" and after all checks I have a solid cursor on the top left.

Could you help me please ?

Thanks in advance.

Fred

Solid cursor, not flashing? Possibly your desktop environment is trying to load but the graphics driver is failing.
Try booting to a console login and run

Code: Select all

apt install --fix-missing
BTW I fixed your title, it read "GRUM".

Hi @sunrat ,

I'm in "Debian GNU/Linux 12 tty1" but I don't remember my login :(..

Could you help me how to get my username ?
Thanks...

Presumably you didn't set a root password then. Can you log in as your user and run the command with sudo?

Can you explain me how I can do that ?
I'm newbie...
How can I show my local users ?
Probably I don't remember the right username .

thanks

Sorry I don't know your username.
It will be listed in /etc/passwd, or your home directory will be called /home/username/
You could boot a live USB distro to look at your files.

I always just set my first name as my username. There's only a small chance I will forget that. :mrgreen:

I tried some solutions:
I booted with: init=/bin/bash
root@(none):/# mount -o remount,rw /
I have "opts: errors=remount-ro"
if I try: "sudo mount -o remount,rw /"
I have "sudo: account validation failure, is your account locked ?"

Any solutions ?

Edit: I'm sure at 100% about username...
Can I lunch your command "apt install --fix-missing" via a Live distro for repair ?
Thanks

You could run as chroot from a live distro, but it would be easier just to reset the root password - https://www.tecmint.com/reset-forgotten ... in-debian/ and then login as root.

Might be easier for you to install again, just take backup of your important files before.

Do the alternate tty's work?
<Ctrl><Alt><F4>
...or F2 or others, depending.
