[Bug 1407375] Re: Segfault on Install with Radeon + Intel iGPU both enabled

 

The installer will run and completes now, even with the integrated
graphics enabled. However, and this is really weird, after first reboot
it seems as though the graphical login screen crashes and restarts over
and over again. I can hear the ubuntu welcome drum beat thing over and
over. On screen I can watch most of the displays enter graphical mode,
then they exit back to the console before starting again.

Should I do the apport-collect command or do a new bug report?

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

Status in xorg package in Ubuntu:
  Incomplete

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.
