Hi
I tested the installation of ubuntu mate 15.10.
Installation went well.
booted to the login prompt ,then logged in and created an xorg.conf
file.
Then sudo service lightdm start and then joined the graphic's login.
Here login failed with this errror : startup of the session failed.
Tried to install another desktop instead of Mate but got this error
Temporary errors when setting up ports.ubuntu.com.
