I have to enter the password 2 times on this computer with Ubuntu 11.10 and other one too. I type the password, press enter and it came back to login screen again! If I select to not ask for password it doesn't matter, when gnome/unity is loaded and I start to use the computer it "resets" and change to login screen. I installed Ubuntu on this one yesterday. I have installed Burg (I think this have caused these problems.)
And the other problem is that the splash image at boot looks like text mode (no image,only text). I have tried with Super Boot Manager, the Plymouth options, but it doesn't work yet.
