[X2Go-User] Fedora 36 and glx fails with GLXUnsupportedPrivateRequest

[Norman Gaywood]

On Fedora 36 we have:
libglvnd-1.4.0-2.fc36.x86_64
libglvnd-glx-1.4.0-2.fc36.x86_64

On Fedora 35:
libglvnd-1.3.4-2.fc35.x86_64
libglvnd-glx-1.3.4-2.fc35.x86_64

I managed to download the  libglvnd* packages for F35, and on an F36
system, I downgraded:
dnf downgrade  ./libglvnd* ./glx-utils*
and rebooted.

So now on my F36 system I have:
libglvnd-1.3.4-2.fc35.x86_64
libglvnd-glx-1.3.4-2.fc35.x86_64

(I've trimmed the package lists in the above, there are more libglvnd*
installed/downgraded).

And the same behaviour occurs:
$ glxinfo
name of display: :50.0
X Error of failed request:  GLXUnsupportedPrivateRequest
  Major opcode of failed request:  143 (GLX)
  Minor opcode of failed request:  17 (X_GLXVendorPrivateWithReply)
  Serial number of failed request:  27
  Current serial number in output stream:  27

So this suggests it's not the upgrade from 1.3 to 1.4 of libglvnd-glx ???

glxinfo is part of the glx-utils package, which I also downgraded. But they
have the same version number:
glx-utils-8.4.0-12.20210504git0f9e7d9.fc35.x86_64
glx-utils-8.4.0-13.20210504git0f9e7d9.fc36.x86_64

So, I'm not sure what to look at next.
