Listmates,
glxinfo is causing a segfault on my toshiba laptop. At first I thought the
problem was video card related, but after googling the issue it looks like both
nVidia and ATI cards are affected eliminating my first guess. Basically, what
is happening is this, "running either glxgears or glxinfo results in a segfault
being generated:"
