Indeed.
I'll return to the suggestion to use DontVTSwitch. With a locked sceen
it is effective in preventing switching to a console with CTRL+ALT+FN
and chvt even if the sudo timeout hasn't been reached.
An unlocked screen plus 'ps ax' and 'kill' enable the bringing down of X
no matter what the length of the sudo timeout is or whether DontVTSwitch
is operational.
