This was my first idea, the symlink to be able to switch though the "alternative" script, but this seems to be rejected, that is why I tried to fixed it using the libmap.conf, but libmap.conf won't solve the libglx.so solution as it is opened from its path iirc. regards, Bapt --gDGSpKKIBgtShtf+ Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (FreeBSD) iEYEARECAAYFAk9Qq7IACgkQ8kTtMUmk6EwEwACgluUD7n+iy3CfdhsBMhP61a0M 01MAniJXtk+etLHGwFLRLa6SQBV/IRPr =kBGH -----END PGP SIGNATURE----- --gDGSpKKIBgtShtf+--
