Re: XF 4.x config (was RE: [PLUG] how do you change resolutionsetting after the install)

[LeRoy Cressy <ldc@netaxs.com>]

There are some things that you just have to do by hand.  Most of the
configurators do not handle high end monitors very well.

Using your favorite text editor hand edit your XF86Config file.

The important items in this are:   DefaultColorDepth 32

which automatically sets the color depth to 32 BPP instead of having the
system default to 8 BPP

Or this is like runing 
	startx -- -bpp 32

The following subsections specify the resolutions beginning with the
first one as the default.  With X you can switch resolutions on the fly
with <CTRL><ALT><Keypad +> This will recycle you through the various
resolutions in your screen section.

The first resolution is the default.  Also, you might want to make your
own modelines for your monitor.  For instance, I've found that some of
the ``standard'' modes are not good, and normally they don't include the
high end graphics mode 1600x1200.

I have also found that sometimes there are resolutions that you don't
want or desire so I take them out using only the resolutions that you
want.  

Another important thing to note is not all applications will run at 32
BPP.  They will all run at 8 BPP though this color depth only has 256
colors.
