Matrox Millennium G450 AGP video card

	
>Description:

I couldn't enable direct rendering on my G450, and I noticed that
"LIBGL_DEBUG=verbose glxinfo" said:

libGL: XF86DRIGetClientDriverName: 1.1.1 mga (screen 0)
libGL: OpenDriver: trying /usr/X11R6/lib/modules/dri/mga_dri.so
libGL error: dlopen /usr/X11R6/lib/modules/dri/mga_dri.so failed (/usr/X11R6/lib
/modules/dri/mga_dri.so: Undefined symbol "XML_SetElementHandler")
libGL error: unable to find driver: mga_dri.so
name of display: :0.0
display: :0  screen: 0
direct rendering: No

It seems that libexpat is not properly linked.

Preloading /usr/local/lib/libexpat.so temporarily fixes the problem:

>How-To-Repeat:
        
Set LIBGL_DEBUG=verbose and run libGL related commands such as
glxinfo, glxgears, and xdriinfo

	
>Fix:

I'm not sure which library should be linked with libexpat...
