Graphics Administration Guide
configuring an X Server on HP-UX
The following is an example of setting the various logging options. The Verbose and LogVerbose
options are set so that only error and fatal error messages are sent to
stderr
and the log file.
The NoLogging option uses
/dev/null
to be the log file. It overrides the LogFile specification
in the Files section. Commenting out NoLogging opens
/tmp/Xlog.log
and sends all
messages directed to this log file.
Section “ServerLayout”

Glx visual suppression
This option “hides” visuals. It reduces the number of visuals made available to clients. The
example that follows demonstrates how to suppress all visuals except for the most capable of
each class of visuals.

The user can also selectively “hide” classes of visuals. For example, to suppress any visual that
has either Alpha planes or Stencil planes, do:
Option
“SuppressGlxVisuals”
“NoAlpha & NoStencil”
The options can be white space, ampersand (&), or comma (,) delimited, and must be enclosed
with a single pair of double quotes.
