That's strange - could there be a problem with your graphics driver? 
Would the Alt-Sysrq REISUB sequence [1] help?

Sorry, I think I didn't write it clear. I didn't want to say that your 
choice of runlevel 1 was wrong. However we often see here people 
expecting runlevel 5 to be default runlevel. I was expecting the same 
coming from Suse many years ago. But for Debian derived systems, the 
default is 2 and there is no difference between the runlevels 2 to 5. 
So, as you were playing with the init command, I thought I should warn 
you about the unexpected behaviour.
