I installed Ubuntu Studio 13.10 from a minimal CD, and then upgraded to 14.04. But since the cd install, I have been trying to change from gdm to lightdm. I have tried sudo dpkg-reconfigure gdm, sudo dpkg-reconfigure lightdm, reinstalling lightdm, but none of this works for me. Any idea?

Thank you!


I am not allowed to post an answer right now, so here it is if someone needs it before I can write a real one.

Ok, I found the answer on this thread: Is it possible to use the 'unity-greeter' for LightDM on Xubuntu 11.10? Turns out lightDM was activated, but the interface looked different. The greeter I had was called lightdm-gtk-greeter and the one I was used to unity-greeter. So all I had to do was to change the file /etc/lightdm/lightdm.conf

Oh, well done for getting there though :D – Ads20000 Apr 24 '14 at 20:45

Have you rebooted? Also try

sudo gdm stop
sudo lightdm stop
sudo lightdm start


sudo service gdm stop
sudo service lightdm start

Own knowledge
Inverse of this

Thank you for your reply. However, the first three make my screen look all jittery and unusable (sorry if this is a bit unclear); and the other two do not work, ubuntu has a problem with the keyword stop – Ghuizing Apr 24 '14 at 19:14
