That's true for Xorg, because Xorg is the thing which provides GLX in
the first place, so it cannot use GLX itself. (glamor on GLX works in
Xephyr though)

Not in X.

glamor failing to initialize in Xorg because Mesa was built without
--with-egl-platforms=drm[,...] was a fairly common problem for radeonsi
users until Marek made it basically impossible. Most of those reports
might have been just on IRC though.
