GRUB_CMDLINE_LINUX_DEFAULT=“text” is not working

[devos50]

it is gdm not gmd.

However i presume you both did a

sudo update-grub

after editing the grub ?

and its the gdm.override there after a reboot ?

Yeah I meant gdm. I did sudo update-grub and gdm.override is also still there after a reboot.

mmmm the answer is i dont know....LOL

I am guessing it is LDM related as 11.10 now uses LDM.

I will play in a Virtual machine in a little while and get back to ya unless someone else chimes in.

cheers

D'oh! Of course, 11.10 defaults to LightDM. So we have to disable LightDM, not GDM...

echo 'manual' | sudo tee /etc/init/lightdm.override

Regarding the original post:

Are you sure "text" is a valid kernel option? I've not seen that used in a Grub 'linux' line before, but I learn something new every day. If it can be used as a kernel option I'd appreciate seeing the link.

I use the following as my kernel options page, but it could be outdated:
http://www.kernel.org/doc/Documentat...parameters.txt

Thank you for your response, but im still booting in GUI. The file lightdm.override is there. Is there anything else I can do?

And text is a valid boot option. I used to boot into text mode with it on 11.04

Thanks for that!

I can't reboot my real system for the moment but the 'text' option did work in my VM's. For what it's worth, it worked in both Natty and Oneiric without any modifications of system files.

Well, not a real kernel option, because it wasn't interpreted by the kernel.

It was a dirty hack used by GDM's Upstart job to prevent GDM from running if the text parameter is present. Here is the relevant part of the code:

cat /etc/init/gdm.conf

# gdm - GNOME Display Manager
...
    # Check kernel command-line for inhibitors
     for ARG in $(cat /proc/cmdline)
     do
         case "${ARG}" in
             text|-s|s|S|single)
                 exit 0
                 ;;
         esac
     done
...

That makes perfect sense now. Thanks sisco311.

ahh cool, i tried with a ldm.override and it wasnt working......i never thought to try lightdm.override

LOL

I was only playing in a VM for the purposes of helping out in this thread, but glad i got it sorted for future reference

cheers

Thanks Sisco311, that works for me
