Hi!
On a Lenovo Thinkpad T470 (with an Intel Core i7-6600U CPU plus an Intel
GPU), I have this problem:
I cannot switch into character based virtual terminals from
the X11 graphical screen. When I press Alt-Ctrl-F[1-7] the
machine "freeze" - it doesn't do anything, mouse / keyboard
doesn't work after it. I can only halt the machine with
the power button.
It worked under 14.1 - on all of the patch levels.
$ pciconf -lv
