Comment 3 for bug 32491

On an iBook G3 Clamshell/Graphite, the Dapper PPC beta live CD gives me the splash screen, but then blanks the screen entirely a few moments into the startup. The screen never comes back after that, so I can't tell what's wrong. The video=ofonly trick doesn't fix it, and neither do any of the other boot-up options on the disk.

I'm now trying to install from the text installer CD of Dapper beta, and it doesn't look good. Everything was fine through the installation, until I rebooted into the new system. Then it came up with a blank screen. I even made sure to uncheck the "1024x768" option in the monitor settings, as this resolution isn't supported by the Clamshell iBook. We're in darkness nonetheless.

When I got the drumbeat, I entered my username and password, and heard the Ubuntu chimes in reply, so the problem seeems to be limited to the video output. But that's pretty important.

Maybe this is related to the horizontal refresh problem documented in another iBook bug thread, or maybe not. In either case, it renders Dapper useless for clamshell iBook owners.

Breezy installed fine on this same machine.
