Blackscreen due to wrong driver and locked out

wont that prompt me for a login again? i mean it asks for a login and a password and i have neither

[GaVenga]

This is the root login. TTY2 is your konto only…
test: login as user root in TTY3

(USB-liveISO is sufficient)

oh okay thank you i´m gonna try that in a second. first i need to shutdown this “emergency” windows leftover and boot in that wonderful manjaro. i am gonna come back and tell you how it went

Edit: soo i tried it and it is greeting me with login:
But i cant do anything because i dont have a login.

If typing root at the prompt, asks for password? Try empty PW or manjaro.

The screen goes :

Login:. (i can type what i want) then
Password: (still doesnt really matter)
Login incorrect.

Happens with login: root
Password: blank/Manjaro

@Imperator-Arch

Login:. (i can type what i want) then

Login: root
Password: manjaro
Login: root
Password: just hit “return”

I did. It too asks for a password. No matter what i enter it ends the same

Then you can root your system by: wie rootet man die Maschine ? (Paßwort vergessen) ?!

or simpler:

God bless you i managed to set a massword with your link behind “or simpler:” now for that driver error🤔
So the tipp i read online said to go with “StartX”

My output is like :
Xauth : file /root/.xauthority does not exist

And way further down the screen:
Vesa: refusing to run on uefi (EE) fatal server error: (EE) no screens found

My pleasure:
grapic driver (in german:)
.
* Falscher Grafikkartentreiber, beheben: *

Währen des Startvorgang, wenn Grub angezeigt wird, die E taste drücken
und dem Kernel folgende Bootoption: 3 nomodeset hinzufügen.
Mit F10 weiter.
So gelangst du zu einen Eingabe prompt in dem du dich einloggst

und folgende Befehle nacheinander ausführst:

sudo mhwd -r pci $(mhwd -li | grep ‘video-’ | awk ‘{print $1}’
sudo mhwd -a pci free 0300

und zum Schluss

reboot

That is the wrong way…

Error: cant find command ‘nomodeset’

NOT in the terminal- in GRUB-menu as shown here:

[HowTo] Resolve an unbootable Manjaro (black screen, login failed, cant boot, etc)

When we have problems gaining access to our systems it is difficult to gather information, let alone fix any problems. Here we will cover common causes and solutions to ‘manjaro wont boot’. TTY If your desktop does not load properly then you might still be able to use most, if not all, functionality by dropping to a non-graphical TTY. By default your system will have multiple TTYs, with each corresponding to an Fx key. Your desktop is assigned to one as well - most often F1. You can change…

I have no grub menu. I can either start manjaro, or hit
E to go into the grub.
Oh and i can enter boot options. But none seem to take the nomodeset

@Imperator-Arch

have no grub menu. I can either start manjaro, or hit
E to go into the grub.

That is what I mean…
Hit E as described in

I did and it says “minimal BASH-like line editing is supported” but there is just a blank screen and if i type nomodeset it says “cant find command”

[GaVenga]

This means your grub is broken…
It can be repaired easily.
But you better call: @stephane by message - he is some where expert - My time today expires shortly, sorry.

Thanks for everything i managed to fix it all in one swift move. The grub really was done for but i googled a fix and found commands to chroot into it (skipped that) and to reinstall it (skipped that too) then there was a simple one to update it and that fixed it. Sadly i dont find it anymore. BUT i still had the driver error to be fixed. So i went into TTy2 and did a quick uninstall (mhwd command thing) and after that i swiftly put a sudo mhwd -a pci free 0300 in to install the RIGHT driver. Thank you i am back in my most loved OS
