[Chimera-users] Broken links, system requirements

[Greg Couch]

Your university might want the regular version of Chimera to remotely 
display data.  In that case, you should set up VirtualGL as well.  And a 
RDP solution, like x2go.  It doesn't perform as well as Chimera running 
locally on the desktop, but it might be sufficient.
