[Bug 1808657] [NEW] Ubiquity fails to boot when selecting the Try Kubuntu (live session).

[Darin Miller]

Public bug reported:

When booting to a live usb via UEFI boot on a hybrid Dell Inspiron 7559
laptop (Intel/Nvidia), the Try "Kubuntu option" hangs.  If maybe-
ubiquity is removed from the boot parameters, the laptop will live boot
without issue.  Proceeding directly to install works fine.

Another workaround is to add "nomodeset" to the boot parameters.  But
nomodeset forces a VGA boot. VGA on a 4k screen provides a very poor
Live session experience.

I will reboot again with quiet mode disabled to see if any  additional
errors are displayed.
