I did something terrible this morning you can see here.

Now that problem was fixed , apt was working fine and so was the update manager .

after installing all updates , I rebooted.

And I could not log in. The login page will like refresh after I enter my password , every time. Then I installed KDM in place of LIGHTDM , and now I have no Unity shell , no panel , and the display settings gives an error

*GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface `org.gnome.SettingsDaemon.XRANDR_2' on object at path /org/gnome/SettingsDaemon/XRANDR*

Any help will be appreciated.

It would be better if I can revert back to lightdm – Ubuntu_beginner Jun 28 '13 at 11:08
