There is no mouse or X windows config on the SPARC. The 8 bit server
is installed by default. If you want to use the 24 bit server (for TCX
cards), you need to install the Xsun24 package.
If you only have a bwtwo framebuffer and want to increase performance,
install the XsunMono package. Installing both of the above
requires you to restart X windows. Also, you can uninstall the
Xsun package if you use one of the above servers.
