Hi Victor,

With glxgears I observe a similar behavior as with VMD: If I start
glxgears logged in from an older installation (openSUSE 12.2) then
glxgears works remotely (I see the wheels). However, if I start glxgears
logged in from a newer installation (openSUSE 15.2) then I get the error
message:

X Error of failed request: BadValue (integer parameter out of range for
operation)
   Major opcode of failed request: 153 (GLX)
   Minor opcode of failed request: 3 (X_GLXCreateContext)
   Value in failed request: 0x0
   Serial number of failed request: 26
   Current serial number in output stream: 27

Interestingly, if I log in from the installation with openSUSE 15.2 (AMD
video card) to a desktop with openSUSE 15.4 (Intel video card) then
glxgears and VMD can be opened remotely. So the problem seems to occur
only when I start a openGL window (glxgears or VMD) from a server with
NVIDIA proprietary drivers to a client which has a recent installation of
openSUSE (and does not have NVIDIA proprietary drivers).
