There is no problem in VMD installation because when I am opening it remotely from another PC everything is fine.
One and the easiest option is reinstallation of VMD. Check the OpenGL driver and update if available new versions of this driver. IF you are using Ubuntu update all software. Sometimes X server fails due to bad match of both drivers.

The main problem is the VMD is installed in a cluster and I am opening this using ssh. Only for my PC I am having this problem. When I am opening the same VMD from some other PC it is working fine.
I am not able to fix the problem for my PC.
while u r entering to the cluster use the following command ssh -X login@..... Then try to open VMD.
This error is due to compatibility problems of the GPU driver with OpenGL. Have you recently updated the nvidia driver ?. Sometimes it happens that when the driver is updated incompatibilities of this type are created. I recommend you uninstall the nvidia driver that you have, restart the computer, install the latest version and then reinstall the OpenGL, Mesa libraries and CUDA. If it still does not work, try installing an earlier version of nvidia or change to property(open source or nouveau) version.
