hw_cursor and sw_cursor are the opposite of each other, and only one
should be enabled.
Fortunately, newer video cards are getting progressively better at reporting their
capabilities to software, so the need for driver options is steadily diminishing.
3.13 LightSteelBlue and Other Color Names
Video hardware uses varying amounts of red, green, and blue light to generate color.
On most video cards, this is specified as color triplets??”three values representing the
amount of each color.
Color triplets are easy for the server to understand, but miserable for humans. It??™s
much easier for us to understand a color name such as orange than a color triplet
such as (255,165,0). X provides a mechanism for cross-referencing color names to
triplets, enabling you to use color names in command options and configuration
files.
The Files section of the server configuration file usually includes an RGBPath entry.
This specifies the location of a file that maps color names to color triplets; the file is
traditionally named rgb.txt, and most distributions place it in /usr/share/X11/. Some
other servers use a compiled version of this database, named rgb.db.
Several versions of this file have been in existence, but the current one has been in
use for many years.
