علتش بخاطر نبود کارت گرافیک هست:
Choosing a graphics card
Since the images displayed by Chimera are designed to be manipulated interactively, hardware three-dimensional graphics acceleration is extremely desirable, especially when visualizing and manipulating large protein structures. Chimera will not perform well on computers lacking a fast processor or a good-performing OpenGL graphics card. (And just because your computer works fine with the game Quake doesn't necessarily mean it will perform well with a scientific application such as Chimera.) Choosing a graphics card is difficult, it depends on the size of the structures you wish to visualize as well any other features you need (e.g., low cost, large display support, hardware stereo in a window). To help you choose a graphics card, look at the chimera benchmarks. Also look at our information on hardware stereo.
Graphics Drivers
Often what appears to be a chimera bug, is actually a bug in the graphics driver. Therefore, we strongly recommend that you update your graphics driver to the latest available. In general, we recommend getting the driver from the graphics chip supplier, e.g, AMD, NVIDIA, or Intel. But in some cases, usually for laptop computers, you'll need to get a new driver your computer maker's web site (and discover there are none — the only solution is to ask the computer maker for a new one).
