Hello. An unfortunate sequence of events (beyond the scope of this thread, but involving glitches while using dual DisplayPorts, Ubuntu 17.10 development branch, Intel Linux Graphics Update Tool, GNOME3, encryptfs, and a beta shell extension plugin) have resulted in my system being: unable to login because the plugin crashes any and all window managers installed unable to uninstall the plugin because encryptfs makes it impossible, through a series of complications, to access my ~/.local/ folder (mainly because I cannot mount it). Therefore I whipped out my trust USB thumb drive and discovered, to my horror, that for some reason I cannot induce my UDOO x86 to boot from it. Rather, it keeps booting from the stricken Linux distro installed on the M.2 SSD. Can anybody help me?
