Hi Chris, Thanks. You're the only response so far to that post. Symptoms are consistently the same for all 3 commands (init 1 - telinit 1 - shutdown now). Happens at least on Ubuntu 14.4 and Mint 17. Does not happen on Ubuntu 10.4. Screen briefly flashes. Screen goes totally black. Power remains on. No disk activity. No response to ctrl-d ctrl-alt-del ctrl-alt-F1, ctrl-alt-F2, etc. Hitting reset button or power cycling results in a reboot that includes a disk integrity check. Darnedest thing. First time I think I've ever seen basic Linux commands that didn't work. Looking forward to learning the cause/solution. Otherwise I'll have to learn how to create a GRUB menu and add a persistent (remains after kernel upgrades) "boot to single user" option.

Systems consistently crash when I give any of these commands (in Ubuntu 14.04.1 and Mint 17)...
I don't have a system to test it on so can you describe the crash please?
thanks, Chris
