Is it possible to use the 'unity-greeter' for LightDM on Xubuntu 11.10?

Solution 1:

Yes, this should work. Please have a look at /var/log/lightdm/lightdm.log to see why LightDM is failing to start Unity Greeter.

Solution 2:

I found a solution for this.. it may work.

In my case, I installed Xubuntu 11.10 - which came with LightDM using the gtk greeter. I edited /etc/lightdm/lightdm.conf to use unity-greeter (after installing it, of course) and had the same issue.

In my case, I fixed it by installing gnome-settings-daemon from Synaptic. Seems it might be required by Unity Greeter, but isn't a dependency.

Hope it helps
