Hi All,

sometimes VMD decides to start up without giving me an OpenGL graphics
window. The OpenGL display window is just grey, no spinning VMD logo or
axes. Once this has occurred I typically have to log out of my X session
to be able to run VMD in display mode again.

Sometimes I can run VMD remotely and display to the local machine (having
ssh handle all the DISPLAY / Xauth stuff) and this might or might not
work (but I want to avoid running VMD remotely, see also comments on this
list why).

I have no idea how the OpenGL stuff works so I would be grateful for any
hints what to do. My home directory is on a nfs served file system---just
in case it might have to do something with time stamps of auth files.
Further system information:
