glxinfo(1) General Commands Manual glxinfo(1)NAME
glxinfo - show information about the GLX implementation
The glxinfo program shows information about the OpenGL and GLX implementations running on a given X display.
The information includes details about the server- and client-side GLX implementation, the OpenGL and GLU implementations as well as a list
of available GLX visuals.
OPTIONS -v Print visuals info in verbose form.
-t Print verbose table.
Specify the X display to interrogate.
-h Print usage information.
-i Force an indirect rendering context.
-b Find the "best" visual and print its number.
-l Print interesting OpenGL limits.

GLXCREATENEWCONTEXT(3G) OpenGL Manual GLXCREATENEWCONTEXT(3G)NAME
glXCreateNewContext - create a new GLX rendering context
GLXContext glXCreateNewContext(Display * dpy, GLXFBConfig config, int render_type, GLXContext share_list, Bool direct);
Specifies the connection to the X server.
Specifies the GLXFBConfig structure with the desired attributes for the context.
Specifies the type of the context to be created. Must be one of GLX_RGBA_TYPE or GLX_COLOR_INDEX_TYPE.
Specifies the context with which to share display lists. NULL indicates that no sharing is to take place.
Specifies whether rendering is to be done with a direct connection to the graphics system if possible (True) or through the X server
glXCreateNewContext creates a GLX rendering context and returns its handle. This context can be used to render into GLX windows, pixmaps,
or pixel buffers. If glXCreateNewContext fails to create a rendering context, NULL is returned.
If render_type is GLX_RGBA_TYPE, then a context that supports RGBA rendering is created. If config is GLX_COLOR_INDEX_TYPE, then context
supporting color-index rendering is created.
If render_type is not NULL, then all display-list indexes and definitions are shared by context render_type and by the newly created
context. An arbitrary number of contexts can share a single display-list space. However, all rendering contexts that share a single
display-list space must themselves exist in the same address space. Two rendering contexts share an address space if both are nondirect
using the same server, or if both are direct and owned by a single process. Note that in the nondirect case, it is not necessary for the
calling threads to share an address space, only for their related rendering contexts to share an address space.
If share_list is True, then a direct-rendering context is created if the implementation supports direct rendering, if the connection is to
an X server that is local, and if a direct-rendering context is available. (An implementation may return an indirect context when
share_list is True.) If share_list is False, then a rendering context that renders through the X server is always created. Direct rendering
provides a performance advantage in some implementations. However, direct-rendering contexts cannot be shared outside a single process, and
they may be unable to render to GLX pixmaps.
glXCreateNewContext is available only if the GLX version is 1.3 or greater.
If the GLX version is 1.1 or 1.0, the GL version must be 1.0. If the GLX version is 1.2, then the GL version must be 1.1. If the GLX
version is 1.3, then the GL version must be 1.2.
NULL is returned if execution fails on the client side.
GLXBadContext is generated if render_type is not a GLX context and is not NULL.
GLXBadFBConfig is generated if config is not a valid GLXFBConfig.
BadMatch is generated if the context to be created would not share the address space or the screen of the context specified by render_type.
BadAlloc is generated if the server does not have enough resources to allocate the new context.
BadValue is generated if config is not a valid visual (for example, if a particular GLX implementation does not support it).
