ibook G4 doesn't boot because of framebuffer

Bug #161741 reported by fuoco on 2007-11-09
Affects Status Importance Assigned to Milestone
usplash (Ubuntu)

Bug Description

I installed Gutsy on my iBook 14'' 1.42Ghz (G4), although the livecd had problems booting - known issues not yet fixed but already have bug reports.
After installing the system fails to boot right at the beginning because of the framebuffer. the screen shows blurry pixels of different colors, and nothing is responsive. Once I start with video=ofonly i can boot normally, but I don't get the bootsplash.

So I found out the problem was usplash, which is installed with /etc/usplash.conf that lacks any resolution setting - once I put there 1024x768 setting, it works perfectly, and even got me back control over lcd brightness which was lost since gutsy.
I do believe it is a serious problem that the file is installed incorrectly configured, and that usplash reacts so badly in that situation (even though according to changelog this was supposed to be taken care of).

Thank you for taking the time to report this bug and helping to make Ubuntu better. This bug did not have a package associated with it, which is important for ensuring that it gets looked at by the proper developers. You can learn more about finding the right package at https://wiki.ubuntu.com/Bugs/FindRightPackage . I have classified this bug as a bug in usplash.

Thanks for your bug report and for your contribution. Can you verify if this bug still happens with latest hardy daily release? You should be able to download latest ISO from here : http://cdimage.ubuntu.com/ports/

The usplash problem is caused by bug 150930 which is fixed in Hardy.

I would like to test that but the cd will only boot with the very new kernel release 7-11, from yesterday. Is there a way to make sure this version is already on the livecd before i download and burn it?

Logically, it has to be linux-image-2.6.24-5-powerpc since it's a daily build, but I can't confirm it since in my case, I can't even boot the CD in my iMac.

I found this file http://cdimage.ubuntu.com/ports/daily-live/current/hardy-desktop-powerpc.list
according to which I think it's indeed 2.6.24-5-powerpc
the thing is I need 2.6.24-7 to boot on this machine (it's the IDE problem that got fixed just now) - maybe you have the same problem on your machine.
Right now I run hardy successfully, but it's upgraded from gutsy - so i have to reinstall from scratch to see if this bug is fixed correctly. I'll wait another day and keep checking that list file...

Can you now confirm if it still happens with Hardy final release?

I can confirm this bug with a iMac. The behavior of the computer is different but it is unable to boot with usplash because it freezes just before the moment where usplash should appears, and boot correctly with nosplash.
