Hi, I recently installed VMD on my linux partition but am unable to get it
to start up in either the gui or text (with -dispdev text) modes, as they
both return segmentation faults before loading the program. I've also
attempted to run VMD through the debug mode: I've copied the output below.
My laptop's graphics are handled by a Kaby Lake integrated graphics card so
I don't think I have CUDA drivers installed, but that shouldn't make a
difference. Let me know if you need more information from me. Thanks.
