Hi Everyone,

I had previously been using VMD under Windows, and it worked wonderfully.
I recently threw off the Microsoft shackles (hooray!), and I am now
running VMD on the exact same hardware under Ubuntu Linux 8.04 (Xfce

I find VMD performance is noticeably worse under Linux. When rotating or
translating a molecule the motion is choppy, whereas before it was
perfectly smooth.

The hardware itself is an Intel Centrino Duo, with the graphics card:
Mesa DRI Intel(R) 945GM 20061017 x86/MMX/SSE2

I don't believe this card supports GLSL (if anyone can confirm this for
me, please do), but as I said, it still worked marvelously under Windows.

Any advice for bringing Linux performance up to speed with Windows on this
hardware would be greatly appreciated.
