Cant select with what window manager want to start X.

I think its for unity-greeter.

The icon that appears next to your username and let you start X with unity-2d, gnome, unity, kde, etc have gone and I cant switch.

I DONT want to change my default window manager, only switch it on the lightdm screen. It has disappeared in Ubuntu 12.10 I think.

Anyone?

  • It changes default window manager. I want to select it in lightdm as before.

  • Yes. Choose lightdm and save it. Reboot the machine. You will be able to see the unity-greeter, where you can select a session

The icon does not appear if you don't have any other session type available. This is what happens after a clean install.

You need to install some other packages providing entries in /usr/share/xsessions, you find which packages with apt-file search /usr/share/xsessions.

  • True! Last install I have unity-2d and some but I have just done a clean install (sorry for not saying).

  • But I have added a file to /usr/share/xsessions to have a "terminal session" but it didnt show up. Clues?

  • I don't think you can add files to that directory and expect them to show in the login manager. You have to install a package providing such items.
