How to disable Alt-Arrow switching of Virtual Consoles?

Here's a one-off fix:

sudo sh -c 'dumpkeys |grep -v cr_Console |loadkeys'

I refactored Tobu's answer to change only the absolutely necessary:

sudo sh -c 'dumpkeys -k|grep -v Incr_Console|grep -v Decr_Console|grep -v Last_Console|loadkeys'

NB: As said this is a one-off fix, and will probably be gone after a reboot.

I had the problem sometimes with Ubuntu 18.04:

sudo kbd_mode -s

Did the job. (at least temporarily)
