Right, this is what I would expect (and it worked some years ago)

that works flawlessly. However, it also crashes when started 
on the remote machine, see e.g.:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
hgb@HGB-PC2:~$ glxgears 
Xlib:  extension "NV-GLX" missing on display "localhost:10.0".
X Error of failed request:  BadValue (integer parameter out of range
for operation)
  Major opcode of failed request:  155 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  23
  Current serial number in output stream:  24
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Best,

Hans-Georg
