Where n = 1, 2, 3, …
Where Size = 2, 4, 8, 16, 32, 64, …
For example, n=2 instructs the X Server to scale all cursors by “2x” so that a 16x16 cursor
becomes a 32x32 cursor and a 9x9 cursor becomes an 18x18 cursor, etc.
If the scaled width or height of any cursor is greater than Size, the scale factor is reduced
so that the net size of the cursor fits into a Size x Size rectangle. Size needs to be a power
of two.
The default value for “n” is 1, or no scaling. The default value for “Size” is 64, or 64 x
64 maximum size.
virtual frame buffer (Xvfb)
Xvfb(1) is an X Server that does not require display hardware or input devices. It
emulates a video frame buffer by using the system’s virtual memory.
Xvfb may be used for: rendering with non-standard depths and screen configurations,
software rendering, providing a way to run applications that don't need an X Server
but for some reason insist on having one, etc.
Generally the user application must use functions such as XGetImage(3) in order to
see what was rendered.
security
See Xf86(1) for information on configuring the Xf86 security policies, files and settings.
connecting to the network
The X Server supports client connections via a platform-dependent subset of the
following transport types: TCP/IP and Unix Domain sockets.
granting access
Information on X Server authorization may be found in the Xf86(1) man pages.
signals
See Xf86(1) for information on how the X Server handles signals.
starting the X Server from the command line
Command line options for the X Server are described in Xf86(1).
