I am testing Oneiric on QEMU guests and they default to 24-bit X display.

How can I change that to 24-bit to 16 or 32 for testing?

Current tickets:

Searching shows that X is started by lightdm.

lightdm man page says:

              Command to run X servers

I can't find the lightdm.conf man page or other documentation.  I just want to make lightdm add "-depth 32" to its invocation of X.

How do I do that?
