Checking Graphics Hardware With gfxinfo

Checking Graphics Hardware With gfxinfo

The gfxinfo command is useful for determining the graphics hardware installed in the system. It is in the /usr/gfx directory, which is not on any of the standard search paths. Thus gfxinfo typically needs the full path name to be specified for successful execution. The command requires no arguments to run.

An sample gfxinfo output for an Indy workstation:

% /usr/gfx/gfxinfo Graphics board 0 is "NG1" graphics. Managed (":0.0") 1280x1024 24 bitplanes, NG1 revision 3, REX3 revision B, VC2 revision A MC revision C, xmap9 revision A, cmap revision C, bt445 revision A Display 1280x1024 @ 60Hz, monitor id 12

This command provides much more information about the graphics system than the hinv command (hinv would simply return Indy 24-bit). From the output of gfxinfo you can determine the number of screens and their pixel resolutions, bitplane configurations, component revision levels, and monitor types. There is no reference page for gfxinfo. Servers without graphics capability will not have this command installed.
