Hi Hans,
it seems that the recent update of intel-vtn broke the keyboard input
on some laptops with libinput:
https://bugzilla.opensuse.org/show_bug.cgi?id=1175599
Blacklisting intel-vtn fixes the issue, so it's likely the falsely
reported tablet mode switch that leads libinput misbehaving. The
affected machines are Acer E5-511 and ASUS X756UX laptops, and they
shouldn't have the tablet mode at all, AFAIK.
Could you take a look? I guess it's the commit cfae58ed681c that
broke. The chassis type is Notebook on those, and this type should be
excluded as well as Laptop.
