Public bug reported:
Problem:
Unable to use 12.04.4 live flash drive to install Ubuntu through UEFI
mode, desktop screen flickering, and VT consoles too.
Workaround:
This does not happen under legacy BIOS mode.
Tried add "nomodeset" kernel parameter during grub menu fixed this
problem.
Further investigating:
14.04 live daily build does not have this problem.
12.04.4 with later kernel does not have this issue, after version
3.11.0-17 .
