Environment Variables

+ +

+Mesa supports the following environment variables: +

MESA_NO_ASM - if set, disables all assembly language optimizations +
MESA_NO_MMX - if set, disables Intel MMX optimizations +
MESA_NO_3DNOW - if set, disables AMD 3DNow! optimizations +
MESA_NO_SSE - if set, disables Intel SSE optimizations +
MESA_DEBUG - if set, error messages are printed to stderr. +If the value of MESA_DEBUG is "FP" floating point arithmetic errors will +generate exceptions. +
MESA_NO_DITHER - if set, disables dithering, overriding glEnable(GL_DITHER) +

+ +

+The following environment variables are only applicable to the Xlib/X11 +software driver. +See the README.X11 file for details. +

MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode +
MESA_CI_VISUAL - specifies the X visual and depth for CI mode +
MESA_BACK_BUFFER - specifies how to implement the back color buffer, + either "pixmap" or "ximage" +
MESA_GAMMA - gamma correction coefficients for red, green, blue channels +
MESA_XSYNC - enable synchronous X behavior (for debugging only) +
MESA_GLX_FORCE_CI - if set, force GLX to treat 8bpp visuals as CI visuals +
MESA_GLX_FX - set to either "fullscreen" for full-screen rendering, + "window" to render into a window, or "disable" to disable the Glide driver. +
MESA_GLX_FORCE_ALPHA - if set, forces RGB windows to have an alpha channel. +
MESA_GLX_DEPTH_BITS - specifies default number of bits for depth buffer. +
