Hi,
The tl;dr about this question is - Is my radeon 520 dedicated card working fine? Do I need to set "xrandr --setprovideroffloadsink radeon Intel" in Wayland to configure hybrid graphics? Xrandr is not working well in weston/wayland.
Long version:
I installed Ubuntu 17.10 on my newly bought HP Laptop (Model:
HP 15-BS576TX) which has a dedicated AMD 520 2GB DDR3 graphics card and integrated graphics Intel HD 620 onboard graphics in a Kabylake Core i5 processor system. This is the first time I'm installing Linux on a hybrid graphics card setup on a laptop.
Now, Ubuntu 17.10 defaults with Xwayland instead of Xorg/XFree86. I find it confusing to configure AMD Radeon 520 dedicated graphics. The confusing part is xrander --listproviders only list the intel hd 620 integrated graphics. Is it not that xrandr and other Xorg tools will not work correctly in wayland?
Code:
xrandr --listproviders
Providers: number : 0
But, lspci -knnn shows that AMD Radeon 520 card is detected:
Code:

I'm booting with "radeon.modeset=1" which is added to the grub bootloader entry.
Now, if I run any app with DRI_PRIME=1 it works and shows below info:
Code:
:~$ DRI_PRIME=1 glxinfo |grep -i Opengl*

OpenGL core profile version string: 4.5 (Core Profile) Mesa 17.2.2
OpenGL core profile shading language version string: 4.50
So, I assumed Radeon 520 is working fine. Then, noticed that there is no mention of gallium 3d? But, why Xrandr is not showing dedicated card as one of the providers?
I see that there is amdgpu driver module also loaded. From the list, R520 card seems to be supported by the radeon driver.
Code:
lsmod |grep radeon
radeon 1470464 0
ttm 94208 2 amdgpu,radeon
i2c_algo_bit 16384 3 amdgpu,radeon,i915
drm_kms_helper 167936 3 amdgpu,radeon,i915
drm 356352 28 amdgpu,radeon,i915,ttm,drm_kms_helper
What needs to be done now? I have no custom scripts or files placed in /etc/X11 directory FYI.
I want to switch to AMD Radeon 520 Dedicated card for resource intense applications. But, Wayland makes it confusing. Will you help?
