It is the 'ssh -X zita2 emacs' that is very slow.
Running emacs locally is perfectly OK. 
The previous install was F9, it used nv, and
the same 'ssh -X zita2 emacs' worked perfectly.
Nothing has changed on zita2.

As far as I can see, the Arch installation tries to enable
3D-acceleration by installing 'drm'. I don't want it. How
can it be disabled ?
