Recent Linux distributions started to disable these shortcut on hardly explainable reasons.
For other shortcuts (like alt/ctrl/backspace for stopping X) there is an easy commandline fix, giving the
terminate:ctrl_alt_bksp option to the
-option flag of the tool
setxkbmap. However, setxkbmap doc seems to remain silent about the other very important shortcut: switching to the console with alt/ctrl/f1-f6.
How could I re-enable it?
I would prefer a shell command, without editing
xorg.conf (which tends to disappear today, another new wonderful improvement of the recent distros).
