Xconfigurator test screen always displays 16bit during install

Florence Beta 2. Installation on a Dell Latitude C600 20GB HDD, 128MB RAM.
During the installatioin in the X configuration screens, when I choose 8
bit or 24 bit, the test always displays 16bit.
I can't confirm this with 4.6.3 and later. Can you test the rawhide version and
let me know if you are still having problems?
Update: This is happening during the installation only so it may be an
installer issue rather than an Xconfigurator issue. Move if neccessary. Have
verified it is still happening in beta 3.
assigning to developer.
I cannot duplicate this behavior with beta 3. What kind of graphics chip does
this laptop have? I suspect that the graphics card may only be capable of a
certain color depth. Can you send the output of ddcprobe?
Ok, I was able to duplicate the behavior using a Compaq Presario 1700T. It has
an ATI Rage Mobility graphics chip with 8 MB of ram. The problem here isn't the
graphics card. Using ddcprobe shows that the card can handle color depths other
than 16bpp. However, I suspect that the LCD screen cannot run in anything but
16bpp. This is a problem, however, because ddcprobe won't work on LCD's...at
least not any of the LCD's that I've seen. This can't be fixed for this release.
