I have some issue with my graphics, so i want to start in the commandline without using nomodeset. I just change them during boot, so that the changes are not saved.

my Grub-config look like this:

menuentry 'Ubuntu' --class ubuntu --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-simple-eb4bd567-94>
        gfxmode $linux_gfx_mode
        insmod gzio
        if [ x$grub_platform = xxen ]; then insmod xzio; insmod lzopio; fi
        insmod part_msdos
        insmod ext2
        set root='hd1,msdos1'
        search --no-floppy --fs-uuid --set=root eb4bd567-946d-4875-88c4-c05bb0be2657
        linux   /boot/vmlinuz-5.4.0-58-generic root=UUID=eb4bd567-946d-4875-88c4-c05bb0be2657 ro  quiet splash $vt_handoff
        initrd  /boot/initrd.img-5.4.0-58-generic

I tried disabling the load_video and changed gfxmode text and removed quiet splash. I get an visible output, but it stops at an entry with "disk manager". So what am I doing wrong? Basically it should like any server grub which do not start any graphical interfaces. I know that it is possible to start without activation xorg.

Thanks for your help and advice.

Okay I get the commandline running, but it stops still with disk manager. Here is a Picture of the last activities before it stops.

To temporarily boot to console, reboot the computer and once you see the GRUB screen, with the first entry from the menu selected, press the "e" key. This allows you to edit the kernel parameters before booting.

Next, look for the line that begins with "linux" (use the Up / Down / Left / Right arrow keys to navigate); "vmlinuz" should also be on the same line. At the end of this line (you can place the cursor using the arrow keys at the beginning of the line, then press the End key to move the cursor to the end of that line) add a space followed by the number 3. Don't change anything else.

This 3 represents the systemd target which is mapped to the old, now obsolete runlevel 2, 3 and 4 (used to start and stop groups of services).

After doing this, press Ctrl + x or F10 to boot to console (text) mode.

From here.
