Hello,

For some time I have 2 screens on my PC both plugged to the 1070TI and it was working.
I decided to play a bit with 2 graphic cards and installed my old AMD R9 280X in my PC with the second screen plugged to it.

So I did follow again https://wiki.gentoo.org/wiki/AMDGPU to re-enable it.

When the PC starts, it begin to display on main screen attached to the nVidia, then switch on the second screen attached to the AMD card to display openrc and finally I have xdm (gdm) displayed only on my first screen attached to the nVidia card and the second monitor goes into sleep and turns power off.

I can't make the second monitor work in KDE.

The problem is this setting makes the old AMD card the default and since the screen on this card is much smaller, I miss the taskbar which is far above and not accessible.

Then I tried to write my file like this:
Code:
Section "ServerLayout"
   Identifier     "X.org Configured"
   Screen      0  "Screen0" 0 0
   Screen      1  "Screen1" LeftOf "Screen0"

   FontPath     "/usr/share/fonts/misc/"
   FontPath     "/usr/share/fonts/100dpi/"
   FontPath     "/usr/share/fonts/75dpi/"
EndSection

Section "Module"
   Load  "glx"
EndSection

   SubSection "Display"
      Viewport   0 0
      Depth     1
   EndSubSection
   SubSection "Display"
      Viewport   0 0
      Depth     4
   EndSubSection
   SubSection "Display"
      Viewport   0 0
      Depth     8
   EndSubSection
   SubSection "Display"
      Viewport   0 0
      Depth     15

   SubSection "Display"

      Depth     16
   EndSubSection
   SubSection "Display"
      Viewport   0 0
      Depth     24
   EndSubSection
EndSection


But this does not work, this starts my second screen on the AMD card, but it stays black and not listed in KDE control center. But this time it does not power off.
And with this latest configuration, Xorg-0.log is this : https://pastebin.com/PPbX4hCS

So you want to try to run an AMD and a NVIDIA card at the same time?

Maybe a hybrid setup could work: https://wiki.gentoo.org/wiki/Hybrid_graphics and als not using the closed source drivers.

Yes, I try to have the nvidia as main card on main big screen and amd as second card on smaller screen.
I have nvidia proprietary drivers and amdgpu opensource ones.
Boinc see both cards and uses both cards, this allowed me to set it up to not use my main nvidia card and it use the amd one.

Problem is xorg, I could have dual screen with AMD card as main card (so KDM and taskbar shown on the small screen), I did not manage to do the reverse.

Is this due to the fact I use proprietary nvidia drivers?
Code:
~ # xrandr --listproviders
Providers: number : 2
Provider 0: id: 0x1b8 cap: 0x0 crtcs: 4 outputs: 7 associated providers: 0 name:NVIDIA-0
Provider 1: id: 0x207 cap: 0xf, Source Output, Sink Output, Source Offload, Sink Offload crtcs: 6 outputs: 4 associated providers: 0 name:AMD Radeon HD 7900 Series @ pci:0000:0b:00.0

Could be. But this is just a guess since I haven't done this setup.
