NAME
       glxinfo - display info about a GLX extension and OpenGL renderer.

SYNOPSIS
       glxinfo [-t] [-v] [-b] [-display displayname]

DESCRIPTION
       glxinfo	lists  information  about  the GLX extension, OpenGL capable visuals, and the OpenGL renderer on an X server. The GLX and renderer
       info includes the version and extension attributes. The visual info lists the GLX visual attributes available for each OpenGL capable  vis-
       ual (e.g. whether the visual is double buffered, the component sizes, Z-buffering depth, etc).

       Command line options include:

       -t      By  default  the visual info is presented in a concise 80 character wide tabular format. The -t option directs glxinfo to produce a
	       wider, more readable tabular format.

       -v      Directs glxinfo to generate a verbose format output style for the visual list similar to the info of xdpyinfo.

       -b      Print the ID of the "best" visual on screen 0.

       -l      Print interesting OpenGL limits.

       -i      Use indirect rendering connection only.

       -display displayname
	       Specify the display to query.

ENVIRONMENT
       DISPLAY To get the default host, display number, and screen.
