FYI, MATE is carrying on the Gnome2 banner (http://mate-desktop.org/). What
version of X are you using? Do you have glx loaded? (In _very_ old versions of
X, you had to explicitly say 'Load "glx"' in the config.)

Just edit the waffle code to remove that stupid check, it's likely BS:

https://github.com/waffle-gl/waffle/blob/master/src/waffle/glx/glx_config.c#L73

            if (!wcore_config_attrs_version_eq(attrs, 10) &&
!dpy->ARB_create_context) {

Make that say like

if (wcore_config_attrs_version_ge(attrs, 30) && !dpy->ARB_create_context)

If anything else fails in that function, just remove that check... it should
work out.
