I've installed the Ubuntu 12.04.1 "rock solid" release. Everything works fine apart from the fact that during start-up the usual purple screen and Ubuntu logo doesn't appear. Only a black screen and blinking cursor is visible. Then after a while, for a fraction of a second, the Ubuntu logo and purple screen comes and disappears to the login page.
I tried Plymouth but it didn't help in solving the problem. It did end up changing the logo to a more artistic one. Can any one please help? Ubuntu is installed on my ASUS 1225c netbook.
