Thanks for the feedback.

Well at least that's a new starting point. :)

What video card do you have in that machine? I have two machines with 
Intel graphics which also showed a funny display (after the upgrade to 
xenial) and there I could avoid the problem with an additional grub 
config line in "/etc/default/grub":

GRUB_GFXPAYLOAD_LINUX=text

However that would not help if you can't start the live image because 
there is no grub involved and I have no idea what would be an equivalent 
kernel option.

OTOH you could add that grub option to your current lucid system and 
then upgrade the system to precise and trusty with do-release-upgrade or 
updatemanager. But of course I can't guarantee that the grub line helps 
against your funny display.
