Ugh. That is going to be crappy for systems which don't actually require
a non-free driver and may behave badly if it is disabled (e.g. intel).
Use case:
User wants a single image to use on two home systems, one of which
requires non-free and one doesn't.
probably not all that rare ...
Wouldn't it be better to disable modeset for specific chipsets, and
wouldn't that be better to do in the package providing the driver that
behaves badly with modeset enabled? e.g. intel driver turns it on by
providing /etc/modprobe.d/i915-kms.conf which contains:
options i915 modeset=1
So, the opposite of that, and with the option only being applied to
radeon (and/or nvidia if it turns out it needs it too).
Do *all* radeons behave better with modeset disabled, or just some? (and
are there any that behave well only with modeset enabled and not with it
disabled)?
I'm very uneasy about this change without checking it out on a wider
range of hardware.
