Updated title & description, because I found out there are much more
possible key combinations.

** Description changed:

- I can reproduce this: 
+ I can reproduce this:
  If i hold the LEFT-Cursor Key and press CTRL (LEFT+CTRL as in CTRL+c to copy) my Keyboard stops working. Mouse is still working.
+ 
+ 
+ [UPDATE];
+ Investigating a bit more systematic, I found out that this happens not only with LEFT+CTRL but with mostly __any__ key in Combination with +CTRL. (Even ENTER, Backsp, Tab, Esc, F1...F12 are affected)
+ 
+ The only exceptions are the following keys:
+ SHIFT
+ ALT
+ ALT_GR
+ CAPS_LOCK
+ NUM_LOCK
+ SCROLL_LOCK
+ BREAK
+ PRINT
+ META/Win-Key
+ 
+ Hope this helps!
+ [/UPDATE]

  "Meta-keyboard-commands" outside of X (e.g. CTRL+ALT+BACKSP or
  CTRL+ALT+F1...) are still effective, therefore i can restart X and log
  in again. So i think, this is somehow related to X.
  
  I haven't found anything interesting in .xsession-errors or
  /var/log/Xorg.0.log but i have attached them. I logged the output of xev
  while provocing the freeze:

  I have tested several keyboards (HP SDL4000 PS2; Cherry RS 6000 USB) and
  the problem ist reproducable with all of them, so this is not related to
  a special keyboard- or connection-type.
