I added a section to an xorg device config file and now can’t boot up. The system just hangs shortly after starting X. Came as a surprise as when I have made mistakes before I have finished up in the kernel or X has ignored them.
My usual answer to this would be to boot up Knopix via a dvd but there are problems there as well. Gets so far and eventually states that it can’t find it’s files.
I then remember that the 12.3 install has a rescue system on it. This gets so far and then it hangs and the scroll and caps logs flash. A green line runs along the bottom of the screen and that’s it.
The machine is an HP420 workstation that uses EFI boot and also offers legacy boot. Tried all options on boot order and have manages to get it to boot to the cd from power up. Also tried booting from the cd/dvd options via a boot menu. The home partitions are raided in Linux. The system files are on a flash disc. Temp files on another disk.

Your machine boots, it just does not start graphic mode. You can
probably boot fine in text mode. For this you have to enter “3” on the
grub command line. IIRC, you have to type “e” before boot starts, to get
into the editor mode of grub, then on the kernel line add a 3 at the
end, then allow the boot to continue.

I’m sure you can.
It is not ctrl-c. At the boot menu just press any cursor key, for
instance, and boot stops. Pressing ‘e’ pops the simple editor for the
entry highlighted by the cursor, and an insufficient help text below.
I’m assuming grub2, which is the current default. If you have grub1, say
so because the procedure is different but easier.

I downloaded a more recent version of Knoppix and fixed the file with that - sudo leafpad from it’s console. I will try the arrow and e and make a note of it. Think I would like to add a console start option to the boot menu. Looked in YAST but I don’t have the ones it shows. Only earlier kernels. It also shows that I am using grub2-efi
