(solved) Xorg fun: portrait and landscape

Hi,

I added a screen to my setup. I now have:

* One 1440p @ 144Hz display, hooked up to a Radeon card (amdgpu), Display Port, primary display on my desk
* One 1080p @ 60 Hz display, hooked to an intel built-in GPU, VGA cable, portrait mode, right of 1440p display

This is what I want (picture), this is what I see (picture).

In the white (it's actually not white, but a solid color that I can set) area, my cursor is OK: pointy side up, moving as expected. The red rectangle represents the physical limits of the screen, and the cursor can't move over it. However, you can see that the content is rotated. If my cursor is at the bottom of the screen in the blank area (where URxvt is supposed to be), then the URxvt window gets focus. If the cursor is at the top of the screen (over mpv), then mpv gets the focus.

In [c]/etc/X11/xorg.conf.d[/c]:

./00-keyboard.conf
# Read and parsed by systemd-localed. It's probably wise not to edit this file
# manually too freely.
Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbLayout" "fr"
EndSection

./10-rat7.conf # irrelevant for this test, I hope
Section "InputClass"
    Identifier "Mouse Remap"
    MatchProduct "Mad Catz Mad Catz R.A.T.7 Mouse"
    MatchDevicePath "/dev/input/event*"
    Option "ButtonMapping" "1 2 3 4 5 6 7 8 9 0 0 0 0 0 0"
EndSection

./20-amdgpu.conf
Section "Device"
  Identifier "AMD"
  Driver     "amdgpu"
  Option     "DRI" "3"
  BusID      "PCI:1:0:0"
EndSection

./20-i915.conf
Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
  BusID       "PCI:0:2:0"
#  Option      "Rotate" "left"
#  Option      "TearFree" "true"
#  Option      "AccelMethod" "sna"
EndSection

Further tests I conducted:

* If I set the VGA display as "normal" rotation, everything works perfectly fine. GlxGears works like a charm!
* If I set the VGA display as "inverted" rotation, the windows have the same gravity as "normal", meaning that they are upside-down. The cursor is the only thing that works as expected. GlxGears glitches like hell, it's horrible.
* Other rotations end up with even stranger things...
* Other resolutions don't change anything: same symptoms, bigger pixels.

xrandr output: http://ix.io/17Cv
If I remove the intel xorg.conf(5) file, the screen disappears: http://ix.io/17CI

And that's it.

Re: (solved) Xorg fun: portrait and landscape

full xorg log and lspci -k output please.

How are you starting X and which wm/de are you using ?
what's in your ~/.xinitrc ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

(A works at time B)  && (time C > time B ) ≠  (A works at time C)

I'm using bspwm, but the issue is the same with i3 and awesome.

Re: (solved) Xorg fun: portrait and landscape

I fixed the problem:

Driver      "intel" -> Driver      "modesetting"

I'll update the wiki to reflect this
