I'm running compiz 0.8.2 with compizconfig on Scientific Linux 6.2 with Gnome 2.28.2. In the compizconfig "General Options" I have "Desktop Size" set as follows:
Horizontal Virtual Size: 6
Vertical Virtual Size: 1
Number of Desktops: 1
This gets me the layout I want, i.e. 6 workspaces in a horizontal layout. Ctrl-alt-cursor-keys work fine for switching between them. However, I can't figure out how to get key bindings for specific workspaces. I've tried enabling "Viewport Switcher" in compizconfig, and tried various combinations both in "Number-based viewport switching" and "Go to specific viewport", to no apparent effect.
My first thought was that something else was eating the specific key bindings I chose, but I think I've tried every combination of shift, control, alt and super (i.e., the Windows key) by now.
I tried setting 6 desktops under "General Options" instead of one desktop with horizontal virtual size 6, but that doesn't seem to make a difference either.
What am I missing?
