[LightDM] How to change depth of display from 24-bit to 16 or 32?

[Ken Stailey]

Let me ask this a different way.

How do I launch X from lightdm with a command line option?

I tried adding
xserver-command="X -depth 16"

to /etc/lightdm/lightdm.conf and lightdm would no longer start the X server.

Thanks,
Ken

Hi,

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:

      --xserver-command=COMMAND
              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?

Thanks
