however there is a different problem which is visible when you run for
example..

The window doesn't render unless you resize it couple of times and then the
application becomes
I have managed to get a solution for this issue by following the below
steps
Scenario 1:
1. Set intel to UXA mode and activate radeon DRI3 using the below xorg.conf
settings
2. Restart mdm by login out and loggin in again (I have experience very slow
rendering login page - Linux mint)
3. Issue
I confirm the above findings on latest Linux Mint available kernel
4.4.0.36 however I also noticed
sudo DRI_PRIME=1 glxgears works
whereas
DRI_PRIME=1 glxgears gives a blank screen.

That seems like a regression or the newest kernels weren't patched.
Currently using 4.4.14 and it still works.

Some news.
I updated the kernel to 4.4.13. Now I don't have error messages is dmesg.
Added radeon.dpm=1 radeon.modeset=1 to /etc/default/grub file (not sure if
everything is needed).
sudo update-grub and reboot
Although I still cannot switch between the cards with DDIS, but I can run

Attached dmesg output about this.

change to the dedicated GPU no matter how I try. My error messages in dmesg are
basically the same as mentioned above.
Also, when I stop lightdm I get the title error: [drm:si_resume
