--- Comment #4 from Daniel Vetter <daniel at ffwll.ch> ---
Both bugs are still wontfix, but not because we don't care here from the
drm/i915 driver team, but because our driver can't fix this ....

lid detection is acpi stuff, you need report this against the kernel's acpi
team and work together with them figuring out how to solve this. Our driver
doesn't do anything really with lid detection, safe for fixup up chaos that
some really old BIOS make ...

The default is just that, and imo it's a sane one - the aim here is that we
have the highest chance that the user can see the login screen: Which means
enable as manu outputs as possible, but restrict the output size to the
smallest one. Otherwise if e.g. the largest output doesn't work for some
reason, the user won't see the login/desktop because he only sees a tiny part
on the one, working screen.

You're correct that this is X server behaviour shared by all drivers and for
the above reason likely wontfix even there.

If you want a different default, your desktop/login manager needs to restore
that at every boot-up to your preferred setup. If your login manager/DE doesn't
provide such a mechanism, you need to file a bug/feature wishlist there.

Hope this explains why we close all such bugs as wontfix.

Sole exception is if the default picker gets confused becuase the kernel
detects an output which isn't really there (ghost output bugs). That's a kernel
issue and needs to be fixed. But afaict this is not the case here.
