Today I tried installing Ubuntu Lucid Lynx in a VMPlayer on my Windows 7 machine. Even though the installation went very fine, I was unable to enter the password in the login, looked like my keyboard is not responsive in the VM. I made a quick search on the net and was able to figure out that this has been the problem with many people. And the answer I came across suggest me to follow few steps and it worked.
