Apparently, VMD 1.9.4 alpha 8 crashes locally too, when using Intel DRI
linux drivers. Checked on Ubuntu 16.04 laptop (OpenGL renderer: Mesa DRI
Intel(R) Sandybridge Mobile) and on Debian Jessie desktop (Mesa DRI
Intel(R) Haswell Desktop).
On the same laptop and os but using Nvidia drivers through optirun, it
starts just fine (OpenGL renderer: GeForce GT 540M/PCIe/SSE2)
Is it a feature, that non-nvidia/low-end/software rendered graphics is
not supported at all?
Thanks,
Pawel
