Ubiquity fail to launch in 12.10 powerpc

[2blue]

Lubuntu Beta 1 powerpc iso (downloanded 6. September, 01:44 AM Central European Time /Paris)

I have used the Beta 1 powerpc iso of lubuntu 12.10 Quantal availabe for download September 6 (01:44 Central European Time/Paris)
System: iBook G4, 1.42GHz CPU, 512MB RAM

There is a bug with the installer. iso boots fine into live CD, but the installer will not launch properly. The installer window will launch with faint outlines of the window, but does not show anything inside the frames. Other applications seems to work fine. This is a new bug in 12.10, as it worked fine in 12.04.

Same problem network manager will not start as well iso-testing

I can't reproduce this in qemu-system-ppc; the installer is slow (of course, since it's all being emulated) but starts up fine. Perhaps this is a window management problem?

Hi Colin

Yes it could be related to windows management. I booted live CD ones again, and it sounds (literally!) like the installer somehow works, but hard to maneuver or check because there is nothing inside the faintly outlinded window.

Would the coarse pixeled desktop image have anything to do with launcher not showing properly? I can launch terminal with out any noticeable trouble.

Further info

CD boots better with the line "live video=ofonly" and installer window shows fine. However Ubiquity doesn't get much further. It freezes and haults the entire live CD session. I rebooted live CD three times and installer keeps freezing up.

Tried an alternate powerpc iso installation dated 20120912 with the same results on the network manager. The window box appears but has no data and the lightly outlined box. Other apts are affected as well catfish, file archiver but some work luckily pcmanfm and lxterminal seem to work okay. I will keep this install for awhyile in case additional data might help.

As of today - Sept 12 2012:

The only way I can get the live disk install or the alternate install to work is to use an outdated xorg.conf file from:

http://mac.linux.be/content/xorgconf-emac-g4125-radeon-9200-debian-lenny

With that file installed as xorg.conf in /etc/X11 my eMac runs both installs quite normally.

There is another more up-to-date solution which seems to be less machine-specific.

It requires the creation of a file in /usr/share/X11/xorg.conf.d/

called 10-monitor.conf

Details are described at:
http://samuelmartin.wordpress.com/2012/05/29/enabling-resolutions-in-ubuntu-12-04-lubuntu-12-04/

It cleared up the problem here on my eMac G4

ubiquity-dm already fiddles with X by creating

    /etc/X11/xorg.conf.failsafe

Maybe we should add the powerpc quirks to ubiquity-dm?
