Color depth question


I know this has been discussed somewhere before so feel free to point out a relevant thread. In Mepis, I don't see where the color depth can be changed graphically. I suspect that I have a 1024x768x24 display right now. I want it to be x16. I looked in the control center and OS center, but any reference to monitor resolution doesn't have color depth as an option too. What can I change to make it x16? My XF86Config-4 file looks like this:


Section "Monitor"

I noticed that too, but the reason I'm suspecting different is because of Pan. When I used to have SUSE, Pan would run incredibly slow and use 100% CPU when it was running if the color depth was at the default 24. Changing it to 16 fixed it. Now that I'm using Mepis, the high CPU usage problem returned. Any suggestions? Is there a way to see what the color depth is when Mepis is running?
