Even if Alt+SysRq+K does work for you it will likely cause your console (eg Alt F1-F6) to not work again until reboot, because it doesn't cleanly shut down the xserver like C-A-B does. I used it once recently after C-A-B was disabled by default and it worked well enough to get X back but after that I could not go to a console again until I had rebooted.
