I'm running Ubuntu 12.04. This question was asked some time ago, but the answers didn't work for me.
The standard way to boot into console mode used to be to edit /etc/default/grub and set
GRUB_CMDLINE_LINUX_DEFAULT="text". This worked fine until I ran the fix proposed in SoundTroubleshootingProcedure, in order to get sound to work.
Since then, I have disabled the boot-splash-screen, but I can avoid what I presume is the lightdm login prompt screen. All I want to do is disable this gui and be prompted with a console login prompt. (Shouldnt be so hard should it???) I read in three 33416 mentioned above that there was a bug in lightdm (it wasn't recognizing "text" properly as an option for GRUB_CMDLINE_LINUX_DEFAULT.) But this discussion happened more than a year ago, and it's surely been fixed. Yet my lightdm is uptodate (so I'm told when I try to update it with apt-get).
As suggested in one of the above, I tried
sudo update-rc.d -f lightdm remove
which resulted in a hung machine. I managed to recover using recovery mode, but now I still get the gui again.
Another suggestion is to edit /etc/init/lightdm.override. I've done this and set it to "manual" as suggested, but lightdm simply ignores this.
Could somebody suggest how to proceed please?
Thanks very much, Leo
I have also tried commenting out the start on stanza in lightdm.conf, and it does nothing.
The find command gives nothing
