[Launchpad Bug Tracker <1407375@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

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.
