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. SEE ALSO
