Hi Diego,

Thanks for the reply. My question is also about the clients. Do the
clients from which you connect also have NVIDIA with proprietary drivers
installed? What I'm trying to figure out is whether remote openGL (VMD)
works if both server and client have NVIDIA GPUs both with the proprietary
drivers installed.

I am using VMD 1.8.7 and 1.9.2b21, both with the same result.

I am considering such an option. My understanding is that rdesktop works
only to connect to a windows server. Is Nice DCV included in major
distributions? Right now I am using `sshfs` to mount the remote directory
and then start VMD locally.

Thanks!
