Restore USB works on some PCs, but not others

What gives?

URbackup restore USB works fine on some PC’s, but not others. I’ve learned to nail most of the issues; disable secure boot and disable RAID.

However I have couple PCs where the restore USB errors out before the GUI is supposed to launch with an ‘X-server’ error. and just nags me at a consola prompt.

Same USB fires up an older PC just fine and connects to my URbackup server.

Thoughts?
