The Identifier line (here Screen[0]) gives this section a defined name with
which it can be uniquely referenced in the following ServerLayout section. The
lines Device and Monitor specify the graphics card and the monitor that belong to
this definition. These are just links to the Device and Monitor sections with their
corresponding names or identifiers. These sections are discussed in detail below.
Use the DefaultDepth setting to select the color depth the server should use unless
it is started with a specific color depth. There is a Display subsection for each color
depth. The keyword Depth assigns the color depth valid for this subsection. Possible
values for Depth are 8, 15, 16, and 24. Not all X server modules support all these
values.
After the color depth, a list of resolutions is set in the Modes section. This list is checked
by the X server from left to right. For each resolution, the X server searches for a suitable
Modeline in the Modes section. The Modeline depends on the capability of both
the monitor and the graphics card. The Monitor settings determine the resulting
Modeline.
The first resolution found is the Default mode. With
pad), switch to the next resolution in the list to the right. With
