I just installed Ubuntu 14.04LTS on my lenevo G505S laptop. As it, there are many complaints of this laptop not being able to handle ubuntu properly. I have some of mine.
Every time I turn on my laptop, the screen goes purple for about 10 seconds and then black for about another 20 s. And so overall booting time is a little more than half a minute. Which is kinda sad.
I'm assuming something is going on before the computer starts up?
