[Trisquel-users] Can't get Mate to work in my Trisquel (7), can anybody help?

[qazxswedc]

In installed both Mate and Unity using these links, respectively:  
https://trisquel.info/en/wiki/installing-mate
https://trisquel.info/en/wiki/how-install-unity-desktop-environment-and-create-session-entry-trisquel-70
I also removed some Unity parts via the following commands:
usr/share/xsessions/ubuntu.desktop
/usr/share/gnome-session/sessions/ubuntu.session

Could anybody help me?
Thanks!
