[Therion] Loch fails to start in Debian

[Bill Gee]

Several weeks ago James Begley and I found pretty much this same problem in 
Fedora 25.  When using the NVidia proprietary driver (version 375.66), loch 
fails to start with an error 

	Error: glXCreateContent failed

In my testing I found that the open-source Intel display driver (part of the 
Fedora distribution) and the VirtualBox display driver both work.  They do not 
show this message.

I do not have a Fedora 25 machine with Nouveau driver, so I have not tried 
that.  The only machine I have with Nouveau is CentOS6 and it is dedicated to 
running VirtualBox virtual machines.
