Don't ever use the root account for daily usage. It's like driving your
car while you haven't finished major maintenance.
If you follow the VMD installation instructions properly, it will work
from user accounts, as with any other decent software. You should fix
the cause of the VMD problem, or you'll only create more problems for
yourself - such as the above. That said, you'll probably struggle to
actually fix the existing consequences of your root usage... so
re-installing the OS and starting again is a serious option.
These problems have nothing to do with GROMACS, so you should consider
alternative sources of information on the web.
