Public bug reported: 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. ** Affects: usb-creator (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1407375 Title: Segfault on Install with Radeon + Intel iGPU both enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/1407375/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
