Did you reboot since updating the driver?

 

Otherwise try nvidia-xconfig and reboot.

Dear VMD users,

I have Ubuntu 14.04 LTS in my laptop and NVIDIA GeForce 710M graphics card. I have installed VMD recently and when I start vmd, the console shows-up following error.

I have installed the Nvidia driver and Ubuntu detect the card properly. The Systems details shows the same.

When I did cat /proc/driver/nvidia/version, it shows as below..

NVRM version: NVIDIA UNIX x86_64 Kernel Module 331.113 Mon Dec 1 21:08:13 PST 2014
GCC version: gcc version 4.8.2 (Ubuntu 4.8.2-19ubuntu1)

When I diid glxinfo | grep OpenGL, it shows

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 710M/PCIe/SSE2
OpenGL core profile version string: 4.3.0 NVIDIA 331.113
OpenGL core profile shading language version string: 4.30 NVIDIA via Cg compiler
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:

Can anybody help me to figure out why VMD could not able detect the graphics card?

Thanks in advance
