AIUI  " Ctrl + Alt + Backspace "  function like Ctrl + Alt + Delete"  only on vesa,  yet it never seems to function when really needed ie when xvesa has crashed (maybe that's not the right description, hangs...?). 

It seems like the only way to head this issue off at the pass is to invoke text mode at boot instead.


Or am I not understanding this properly??

In cases where Xvesa hangs you can still rely on the Kernel SysRequest feature with combinations like

Alt + Print/SysRq + R
Alt + Print/SysRq + E
Alt + Print/SysRq + I
Alt + Print/SysRq + S
Alt + Print/SysRq + U
Alt + Print/SysRq + B

that's "busier" backwards to remember easily ;) More information about the possible combinations you can find here http://en.wikipedia.org/wiki/Magic_SysRq_key

Cool,   thanks  will work with this on next opportunity.  Though I think the reisub commands are best for an Linux install for a safe shutdown.     I was looking more for a method to return to text mode without the reboot from a booted remastered iso, if there is such a command.   The link seems useful thanks

Perhaps  just " Alt + Print/SysRq + R + I " is what I'm looking for.?

You can try Ctrl-Alt-F1 to get back to tty1, and if that works, troubleshoot from there.
