Resolution Dialog missing for Linux?

After building out our game for Linux 32-bit with Unity 4.0 beta-7, and running the application under Ubuntu 12.04, the game launches without first displaying the Resolution Dialog. Has anyone else encountered this issue and found a solution for it? Is there an alternate way to specify the operating resolution while under Linux?

Thanks in advance!

The config dialog is indeed missing for Linux builds in the current version of Unity.
It is however on the list of things to do.
