[Bug 1420123] Re: [utopic] Black screen on boot (radeon)

 

I too have fallen victim to the same confusing package names before (I
now remember):

   ubuntu-desktop-mir: Legacy fullscreen XMir
   ubuntu-desktop-next: Unity8 login (not totally usable yet but will evolve into proper Unity8).

ubuntu-desktop-mir used to work, but the XMir extension has been
rewritten recently. Just retested this on vivid myself and got some
flickering, stuttering, crash, reverted back to regular X. Don't expect
ubuntu-desktop-mir to work. And even if we did fix it, no fix for that
would get backported to Ubuntu 14.10.

You're encouraged to try out and log bugs against ubuntu-desktop-next
though...

Bug description:
    I'm running Ubuntu 14.10 amd64 with AMD R9 280X using the radeon
  module.  I installed ubuntu-desktop-mir using apt-get.  On boot VTs
  seem to work fine, but nothing displays.  Just a black screen, but my
  monitor detects input and remains active.  I saved dmesg output to a
  file, but after reviewing it I don't see anything relevant.  I've
  attached it anyway.

    Let me know if there's more I can do to help.
