When I try DIGD, I get:
vga_switcheroo: setting delayed switch to client 0
Then, when I shut down X, I get a blank screen.
When I try IGN after shutting down X, I get the same message:
vga_switcheroo: client 1 refused switch

The series is really old! Why is gmux in such a shabby state today, and more importantly: how do I get started hacking on it?
Thanks.
