Thank you Sven,
I'll [try to] reassign to xserver-xorg then. Although #801518 does
have similarities, I am unsure if it should be merged.
I have tried the xorg.conf you suggested, and I hit another problem :
same sequence now leads to
-----------------------------------------------------------------------
[…]
FatalError re-entered, aborting
[ 480.355] (EE) xf86CloseConsole: VT_ACTIVATE failed: Input/output error
[ 480.355] (EE)
-----------------------------------------------------------------------
(mouse/keyboard unresponsive although laptop "fn" keys does respond)
same workaround ('startx' from any of tty2-6)

Alexandre Hoïde
