If you are using grub boot without starting graphical environment like this:
Press e when the grub-bootmenu appears.
Use the arrow keys to find the line looks like this:
linux /vmlinuz=linux root=UUID=...... rw quiet resume=....(… = long snake of numbers)
put systemd.unit=multi-user.target right after rw wie dieser:
rw systemd.unit=multi-user.target resume=....
i do remove quiet to get a more speaky output on boot (rest leave untouched!!!)
Press Ctrl+X to boot with this parameter.
- now you will boot up without graphical environment, and can login normal user and proceed with repairing...
