3.17 Configuring the Resolution of a Screen
Although you can usually set the screen resolution using xrandr, you can also
directly specify it by creating a subsection in the Screen section of the configuration
file:
SubSection "Display"
Depth 24
Modes "1280x1024" "800x600"
EndSubSection
There can be one section for each possible color depth.
The first mode listed in the Modes entry that will work with the screen??™s hardware will
be the default resolution for the display. The user can change resolution using hotkeys
(Section 5.2).

When the user changes resolution, only the displayed resolution changes, not the
size of the screen image. If the screen is configured with a resolution of 1280 ?— 1024
and the user switches to a display resolution of 800 ?— 600, only about one-third of
the desktop will be visible on the display. You can scroll the display around this virtual
desktop using the mouse; when you touch the edge of the screen, it will scroll
automatically.
This can be useful if you want to temporarily zoom in on part of the screen.
