I'm installing Ubuntu on a Compaq Armada M300 laptop acquired as a cast-off from a client.
I tried the regular Jaunty 9.04 install disk, which failed while trying to boot into the live system, and also during the boot of the direct installer.
I then tried the alternate install disk. This failed while trying to enable the framebuffer. The screen slowly faded to white and back down to black, and stuck there.
For further amusement, I tried the netboot install
