Just now I wanted to install Ubuntu on my PS3..... the disc I burned it onto was scratched but I didn't want to waste a DVD so I gave it a try, failed at 6%, no biggie.

Reboot. Back in kboot I typed boot-game-os which didn't worked so I used the alternate power button method and was greeted with the XMB which asked me if  want to use HDMI, of course I selected yes..... bootsound, XMB clicking noises but black screen O_O

tried it again, this time I selected No, same result O_O

tried it again, this time I didn't even got the question on boot the PS3 just beeped quick two times and then powered off.... I was like... OH SH**..... turned it back on..... Question, HDMI, selected yes.... back in the XMB with normal picture on screen..... phew :o
