everytime I try to install ubuntu 12.10 on my laptop i get a blackscreen after clicking on "install ubuntu", "try ubuntu without installation" or "ubuntu live" i tried it with nomodeset, nolapic and acpi=off too but nothing works. Sometimes i even get so a loading screen with nothing but "Ubuntu 12.10" and 4 dots in the middle, after that shortly a blackscreen appears with some text on it and then the complete blackscreen appears. As i tried with "no splash" instead of "quiet splash" it shows me something with graphic and determined in it but it was to fast away in a blackscreen to remember. Has someone any idea what I can do to get this working? Sry for my bad english i'm actually from germany. Sincerely Nalelvon
