Monitor attached to integrated intel graphics not detected after installing fglrx

[dolphy]

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.

Unfortunately fglrx does not support RandR 1.4. The only solution, in your case, would be to use multiple xscreens which I think Kubuntu supports but Ubuntu doesn't (because of Compiz). Unfortunately we do not support this use case. If you do decide to go down this path, you will probably want to disable gpu-manager by passing "nogpumanager" on boot.

The other alternative is to use the open source drivers.

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!
