KDE Color Depth

My name is Matt; I'm very new to Linux.
I've recently downloaded a copy of Mandrake 5.3 (a takeoff of RedHat 5.2, as I
understand it) and successfully installed it on my system.  Everything seems to
be working fine. However, due to my ignorance, I cannot get my X-server
(XFree86 running KDE, I'm not sure what the relationship between the two is- is
KDE a window manager?)  I've run xconf a few times, and managed to change the
default resolution for various color depths, but found no way to change the
default color depth.  Can anybody help me?

A little confused by the way you stated things its looks like you
have already done what you are asking.  An example of XF86Config
is below - you can edit yours.  With startx I start with defaults
8.  You can starts -- -16 for more.  I'm not sure what would
happen if you delete the 8 section below and startx ? it probably
will use 16 or choke.

1. KDE color depth, other issues, on Solaris 7

I can't get KDE to take full advantage of my Creator 3D card on my
Ultra60.

I installed the qt-x11-2.2.2-1 and kde-2.0-1 packages from kde.org.  I
have patch 108376-16 (and all other recently recommended patches)
installed.  KDE started on the first try, which was cool, but I
believe I am not getting more than 256 colors on my desktop, which is
annoying.  I base this belief on the appearance of JPEG images I look
at in the Image Viewer application in the "Graphics" menu, as well as
things like dithering on the clock background.

First question:  how do I tell exactly what the screen resolution and
color depth are, as reported by KDE?  

However, I know I am getting better color depth than that out of X,
because within a SunPCI window I am running NT, and viewing the very
same JPEG images from within that window bring them out in the full
16M colors.  (Or so it appears, and so NT reports.)

Second question:  does this even make sense?  (Aside from the fact
that I just admitted to running NT, that is.)

Also, when I select Help in applications, I am informed that the KDE
documentation is not available.  I am referred (by the file that comes
up in Konqueror) to http://i18n.kde.org/doc/install.html, where I am
informed that

a) the documentation is available online in
   http://www.kde.org/doc/index.html, which is 404-compliant; and

b) (from another link) instructions for installing the docs on a
   non-x86 platform are not available.

I tried doing a 'make install' from kdoc-2.0 sources, and it installed
kdoc (the binary), qt2kdoc and other stuff in what seem to be the
appropriate places.  Yet I still can't see the actual documentation.

Third question:  any suggestions?

Finally, a few of the toys don't work.  kworldwatch can't find
libpng.so.2 -- I'm not sure where that's supposed to come from.  kmoon
crashes with a bus error and dumps core.  A few other little things like
that.

Fourth question:  any suggestions about this?

For general work, though, it's running great.  So nice to have KDE
back on my Solaris box once again.
