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.

NAME

       visualinfo -- displays GL extension and visual info

SYNOPSIS

       visualinfo [-display display] [-visual id]

DESCRIPTION

       This manual page documents briefly the visualinfo  command.

       visualinfo  is  a  small  utility  that	displays all available visuals, aka. pixelformats, in an OpenGL system along with renderer version
       information. It shows a table of all the visuals that support OpenGL along with their capabilities. The format of the table is  similar	to
       that of glxinfo on Unix systems:

       visual	 ~= pixel format descriptor

       id	 = visual id (integer from 1 - max visuals)

       tp	 = type (wn: window, pb: pbuffer, wp: window & pbuffer, bm: bitmap)

       ac	 = acceleration (ge: generic, fu: full, no: none)

       fm	 = format (i: integer, f: float, c: color index)

       db	 = double buffer (y = yes)

       dw	 = swap method (x: exchange, c: copy, u: undefined)

       st	 = stereo (y = yes)

       sz	 = total # bits

       r	 = # bits of red

       g	 = # bits of green

       b	 = # bits of blue

       a	 = # bits of alpha

       axbf	 = # aux buffers

       dpth	 = # bits of depth

       stcl	 = # bits of stencil

OPTIONS

       A summary of options is included below.

       -h	    --help
		 Print help and exit.

       -display display
		 Allows specifying an X display.

       -visual id
		 Allows specifying a specific X visual.
