Hi all,

I am running VMD 1.9 on a Linux x86_64 machine with an nVidia GPU and
the assorted proprietary driver. The first instance says:

Info) VMD for LINUXAMD64, version 1.9 (March 14, 2011)
(...)
Info) Detected 1 available CUDA accelerator:
Info) [0] Quadro FX 3700 14 SM_1.1 @ 1.25 GHz, 511MB RAM, KTO, OIO, ZCP
Info) OpenGL renderer: Quadro FX 3700/PCI/SSE2
Info) Features: STENCIL MSAA(16) MDE CVA MTX NPOT PP PS GLSL(OVF)
Info) Full GLSL rendering mode is available.
Info) Textures: 2-D (8192x8192), 3-D (2048x2048x2048), Multitexture (4)

If I try to start a second instance of VMD though, it says:

Info) Creating CUDA device pool and initializing hardware...
Warning) thread[0] can't init GPU[0] found by device query
Warning) CUDA error: no CUDA-capable device is available
Segmentation fault

I don't remember this happening with previous versions. Any ideas?

Cheers,
Jerome
