Thanks, that did the trick. Here's a reference for others if needed:


Xorg.conf:

Section "Device"
    Identifier     "Radeon"
    Driver         "radeon"
    BusId          "PCI:1:0:0"
    Screen         1
    Option    "AccelMethod"   "glamor"  # Doesn't seem to be used
EndSection

Section "Device"
        Identifier              "Intel"
        Driver                  "intel"
        BusId                   "PCI:0:2:0"
        Screen                  0
        Option "AccelMethod"   "sna" # Unsure if this works
EndSection


# lsmod|grep radeon

$ xrandr --listproviders

Now I wonder if it's possible to start display manager and X with
DRI_PRIME=1? Or that doesn't make sense?
