So current state -
Fresh install today’s image (current live which is reasonably up to date
In an Ubuntu session Ctrl+Alt+t opens gnome-terminal
Adding ubuntu-unity-desktop, switching to lightdm, adding ppa, upgrading g-s-d and reboot, log into unity -
Ctrl+Alt+t does nothing
Actually most or none of the preset bindings (gnome ones??) work ex. PrtSc or Alt+PrtSc, ect.
Custom bindings do work, ex. setting command of gnome-terminal to Ctrl+Alt+g will open terminal or reassigning Ctrl+Alt+t also works
Unity bindings work, ex. super+a, ect.
Additionally installing ubuntu-unity-desktop does not install libzeitgeist or any of the previously default unity lens or scopes…
