[Bug 1511429] Re: Monitor attached to integrated intel graphics not detected after installing fglrx

 

Thanks Alberto.

I have a lot of graphics artifacts in KDE using the open source drivers,
so that is a less desirable option for me.

I just want to make sure I understand you accurately...please correct me
if I am wrong on any of this: you're saying that the best solution for
this under KDE would be to disable gpu-manager and manually configure
the xorg.conf file to create a second screen attached to the integrated
controller. This may be supported by KDE, but it is not a supported
configuration for Unity.

Because this is not a supported configuration for Ubuntu proper, what is
the best path for this bug? I don't know the etiquette, but I'd like to
keep it against the fact that Ubuntu/Unity *doesn't* support this
configuration, and to get support added. The end goal in my mind would
be for gpu-manager to create an xorg.conf file that utilizes the second
adapter.

If that's not appropriate, please let me know.

Thanks!

Title:
  Monitor attached to integrated intel graphics not detected after
  installing fglrx

Status in fglrx-installer package in Ubuntu:
  New

Bug description:
  On a fresh install of Kubuntu 15.10, all three of my monitors were
  auto-detected and usable. After installing the fixed version of fglrx
  (bug #1493888), the two monitors attached to my AMD discrete graphics
  cards are detected and usable, but the monitor attached to the
  internal intel graphics controller is blank screen.

  lspci seems to know that the graphics card is there, but xrandr does
  not. Please see attached logs.

  EXPECTED:
  All monitors attached to both video controllers (integrated intel and discrete AMD) to be detected and usable.

  ACTUAL:
  Only the two monitors attached to the discrete AMD graphics card is usable.
