I am running a custom version of Raspbian on my B+ with a touchscreen. This OS was customized to work with the WaveShare SpotPear A screen they sell. It is configured to auto login to to the desktop as the pi user. I wan't to disable that so I tried the following:
sudo raspi-config; boot to console option- Commented out all autologin lines in lightdm.conf
- Went to /etc/inittab and verified there were no incorrect Entries doing the opposite of this tutorial.
Tried to disable lightdm with the command
Sudo update-rc.d lightdm disable 2giving me this error:update-rc.d: using dependency based boot sequencing insserv: warning: current start runlevel (s) (3 4 5) of script lightdm 'overrides LSB defaults (2 3 4 5). insserv: warning: current stop runlevel (s) (0 1 2 6) of script lightdm 'overrides LSB defaults (0 1 6).Tried
sudo apt-get --purge lightdmgave an error saying stuff depended on it. But things that depended on it could not be uninstalled because it said they already were. So I used aptitude and was able to fix that and finally uninstalled it and rebooted. It brought me back to the desktop again! I checked in the lightdm folder and there wasn't a lightdm.conf file anymore. Just to see what happened I logged off. Which does not show screen but shows the terminal. I proceded to login as pi and type startx. It then showed a message like it had worked talking about who created it etc but did not go to desktop or let me type anything. Ctrl + Alt + Backspace is the only thing that saved me! I then rebooted and it went to the desktop like nothing happened.
Other questions have addressed this question but the answers above worked. I haven't had success with any of these. Does anyone know further configuration possibilities that could fix this issue?
