Testing request: gdm-on-Wayland on hybrid graphics laptops (esp. Macbooks)

[Adam Williamson]

Hi folks!

We have a somewhat-worrying proposed blocker for F22:

https://bugzilla.redhat.com/show_bug.cgi?id=1218787

it appears that after a successful installation of Workstation on the
affected system, GDM-on-Wayland fails to start correctly but also does
not fall through (as it should) to GDM-on-X, leaving the user with a
black screen and no obvious way to proceed. This is obviously a bad
bug, but so far it has only been observed on one test system (a Macbook
Pro 8,2) by one tester. A few other testers have tried to reproduce on
other hybrid graphics systems, but have not been able to.

It would be very helpful to get some more data here. If anyone has a
hybrid graphics laptop and can spare some space (or perhaps attach an
external drive) for a test F22 install, can you please try installing
F22 Workstation TC3 and creating a user:

https://dl.fedoraproject.org/pub/alt/stage/22_TC3/Workstation/x86_64/iso/Fedora-
Live-Workstation-x86_64-22-TC3.iso

then boot the installed system, and see if GDM appears correctly?
Thanks.

Note there is a different bug which causes GDM-on-Wayland to flicker on
some hardware:

https://bugzilla.redhat.com/show_bug.cgi?id=1218688

that's something different, and is a bit further along in the
diagnosis/fix process, so we probably don't need further reports of
that one (though once a fix arrives, it'd be good to have folks test
it).

If you find you seem to be affected by the bug, please add your details
to the report. If you test and find you're *not* affected by the bug -
you see GDM properly - please reply to one of the mailing lists, so we
can get some idea of the proportions of affected vs. non-affected
testers. Thanks a lot for your help, folks!
