Public bug reported:
The Ubuntu 14.10 desktop amd64 live CD gives no graphical desktop on a Apple
MacBookPro 8,3 (A1397) 2011
(hardware described here:
http://www.penlug.org/foswiki/bin/view/Main/HardwareInfoAppleMacBookProA1297 ).
I also tested an upgrade from Ubuntu 14.04.02LTS to Ubuntu 14.10 and similarly
lost the graphical login
as xorg no longer started (only the tty terminal login prompt appeared after
reboot).
Please let me know if any further info is needed to reproduce the issue on your
side, or if you'd need me to
collect any further diagnostic info from the system, I'm a software engineer so
I should be able to follow any
instructions you provide, including compiling patches etc.
I'm somewhat surprised that xorg would stop working on the Apple MacBookPro 8,3
as it uses the
free radeon driver in Ubuntu 14.10 which has worked fine through many many
Ubuntu upgrades
on this particular machine.
To reproduce the issue: attempt to start an Apple MacBookPro 8,3 using the
Ubuntu 14.10 desktop amd64 live CD.
Notice that no graphical desktop ever appears.
Alternately, after a fresh install of Ubuntu 14.04.02LTS, upgrade to 14.10, and
notice no graphical desktop, only
they tty terminal login is presented.
I've tried searching for an explanation through many launchpad bugs, but
haven't found any other reports.
