Section determines the section's name, in this case, Screen.
DefaultDepth determines the color depth to use by default unless another
color depth is explicitly specified.
For each color depth, different Display sections are specified.
Depth determines the color depth to use with this set of Display settings.
Possible values are 8, 15, 16, 24, and 32, although not all of these are supported
by all X server modules.
The Modes section comprises a list of possible screen resolutions. The 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 Ctrl + Alt + + (on the
number pad), switch to the next resolution in the list to the right. With Ctrl + Alt
+ – (on the number pad), switch to the left. This enables you to vary the resolution
while X is running.
