Starting up Ion3 in Ubuntu

Question

How can you start up Ion3?

I installed Ion by apt-get. I have the exec ion in my .xinitrc. I get

>> Unable to redirect root window events for screen 0.
>> Refusing to start due to encountered errors.

Answer 1

I suspect you started another window manager before this one. What's in your .xinitrc before the line exec ion3? Is there a exec startkde, metacity or similar?

If this isn't enough info to go on, I need to know what window manager you're migrating from.
