Title:
  Segfault  on Install with Radeon + Intel iGPU both enabled

Status in xorg package in Ubuntu:
  Expired

Bug description:
  My system is an Intel i7 4770k on an asus Z87 WS motherboard with an
  AMD R9 290X graphics card. With Intel iGPU enabled in the UEFI, the
  installer crashes.

  I have 4 displays, 3 attached to the R9 290X and one attached to the
  onboard graphics.

  I hit ctrl+alt+f1 and looked at /var/log/X.org.0 log and it indicated
  a Segmentation fault. I was able to continue with the install by
  unplugging all monitors but the primary monitor AND disabling the iGPU
  in the UEFI. I was somewhat surprised that it was necessary to
  completely disable the onboard graphics because in many OEM
  configurations onboard and PCIe will be enabled for possible multi-
  monitor configurations.

  After installing, apt-get update && apt-get upgrading the distro, I
  installed the proprietary fglrx driver using software center, and that
  worked fine.

  I re-enabled the iGPU however the system appears to hang hard. On two
  of the displays (attached to the R9 290X) I can see the animated boot
  screen, but ctrl+alt+f1 does not work, and the caps lock light does
  not toggle if I hit capslock. No mouse cursor. I did not try ssh, but
  the system did not respond to a 'tap' of the power button to shut it
  down.

  I would be willing to experiment a bit here if someone can point me
  the right way. I realize I might have to do some things at the command
  line, but I wanted to bring this to your attention because I am not
  sure enabling the iGPU should causes the system to become unusable.

  I am using the official gnome variant of the 14.10 install USB stick.

  I tried both "Try Ubuntu" and "Install Ubuntu" from the UEFI boot menu
  and both options behave approximately the same way in terms of the
  Segfault.
