Dear VMD developers,
THank you for your prompt reply.

I bought Dell Insprion 4100.

Yes, I got Nvidia drivers and kernels installed. There are setting
problems where the virtual screen is bigger than the physical screen, and
the manual from nvidia was not very helpful.
After several laborous testing, I figured out that after adding one line
in modules.conf (options NVdriver NVreg_Mobile=3), the display worked.

OK, I installed openGL version.

OK. After changing VMDSCRIZE to smaller numbers, it works. Thank you very
much.
