The same image works well on real hardware.
Thanks

Status changed to 'Confirmed' because the bug affects multiple users.

To better explain, instead run the ubiquity-dm it jump into live session, but pratically unusable with the graphic really garbled and the windows freezing disappearing and so on.

This bug has been reported on the Ubuntu ISO testing tracker.

A list of all reports related to this bug can be found here:

looks like a dependency issue in ubiquity-frontend-gtk, it currently depends on x-window-manager which compiz provides already...
but indeed compiz cant run on non GL capable hardware so we need either a hard dep on metacity here or even a new definition for a x-window-manager-gl property so packages can define a GL and non GL capable WM

Comment #7, occurred on real hardware, Acer is fully current architecture. I don't know what "non GL hardware is"?

non GL hardware = hardware not capable of doing 3D operations out of the box on an ubuntu image (i.e. without installing a third party driver like fglrx, nvidia or one of the arm GLES drivers)

This hardware is capable of running Unity.

Thanks, Jerry

This happened to me testing this ISO: http://cdimage.ubuntu.com/daily-live/20120822/quantal-desktop-armhf+omap4.img on a panda board.

This bug was fixed in the package ubiquity - 2.11.23

ubiquity (2.11.23) quantal; urgency=low

  [ Luke Yelavich ]
  * Show the accessibility indicator in only-ubiquity as well.
  * Tweak the error message displayed when the accessibility indicator
    cannot be shown, to satisfy PEP tests.

  [ Colin Watson ]
  * Make ubiquity-frontend-gtk depend on the specific window managers
    supported by ubiquity-dm (LP: #1037515).
  * Automatic update of included source packages: flash-kernel
    3.0~rc.4ubuntu22, partman-auto-lvm 45ubuntu1, yaboot-installer
    1.1.22ubuntu1.
