Hi, I am a new linux user, having recently installed kubuntu 7.04 on my laptop. My problem is the following: when I turn on the computer, after the kubuntu proccess bar the login screen should appear- instead, I have a completely black screen, not able to write anything, nor can I see the mouse cursor. I can start the computer normally -and have the login screen- only when I go to the Grub loader menu and choose the option "linux image 2.6.20-16 generic"(the other options are "recovery mode" and "ubuntu memtest"). It's quite disturbing always to have to do that, so could someone give me an advice please...? Thanks.

If you're screen does not go blank until X comes up then I imagine it isn't setup properly for you video card. Can you boot to console (run level 3)? Perhaps the kernel you are trying to use is missing a module that your video card needs. It is hard to tell with the amount of details you have given.
