and after poking around with several configuration/ binaries below is a buggy workaround. but hey! it works!!
tested after re-imaging my pc. The only thing i had to do was correct the config from my previous post.
Section “Device”
Identifier “amd”
Driver “amdgpu”
BusID “PCI:5:0:0”
EndSection
in my pc, i found my AMD GPU to be at hardware ID 6, I used the below script to determine it
shopt -s nullglob
for d in /sys/kernel/iommu_groups/*/devices/*; do
n=${d#*/iommu_groups/*}; n=${n%%/*}
printf 'IOMMU Group %s ' "$n"
lspci -nns "${d##*/}"
done;
now, my /etc/X11/xorg.conf.d/10-render-offload.conf looks like:
Section “ServerLayout”
Identifier “layout”
Screen 0 “nvidia”
Inactive “amd”
EndSection
Section “Device”
Identifier “nvidia”
Driver “nvidia”
BusID “PCI:1:0:0”
EndSection
Section “Screen”
Identifier “nvidia”
Device “nvidia”
Option “AllowEmptyInitialConfiguration”
EndSection
Section “Device”
Identifier “amd”
Driver “amdgpu”
BusID “PCI:6:0:0”
EndSection
Section “Screen”
Identifier “amd”
Device “amd”
EndSection
reboot, went back into display manager and enabled the monitors and it now works!!
one observation i have noticed is, sometimes when powering on the laptop, it does not boot into KDE environment. and xorg crashes with below:
