AMD Radeon 520 graphics card not detected in wayland session when using AMD/Intel hybrid laptop

[Abraham]

This is a new laptop HP 15-BS576TX which has Intel HD 620 Integrated graphics and a 2GB AMD Radeon 520 Graphics card running on Ubuntu wayland session. Intel integrated graphics is only listed, if you check gnome-control-centre details page (See attached images). But, if I run [code]DRI_PRIME=1 gnome-control-centre[/code] to reach details info it shows "AMD HAINAN" as the only card available. So, it seems the Xwayland session not automatically managing hybrid graphics (shifts to dedicated card for resource hungry apps). What I expected is Gnome control centre will list both the cards.

tl;dr: AMD/Intel hybrid graphics not configured correctly in wayland. Dedicated Card is not showing up in system informations.

Here are the details: lspci -knnn shows that AMD Radeon 520 card is detected:

01:00.0 Display controller [0380]: Advanced Micro Devices, Inc. [AMD/ATI] Sun XT [Radeon HD 8670A/8670M/8690M / R5 M330 / M430 / R7 M520] [1002:6660] (rev 83)

    Kernel modules: radeon, amdgpu

and Integrated Intel HD 620 graphics:

Now, if I run any app with DRI_PRIME=1 it works and shows below info:

:~$ DRI_PRIME=1 glxinfo |grep -i Opengl*
OpenGL vendor string: X.Org

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?
I see that there is amdgpu driver module also loaded. From the list, R520 card seems to be supported by the radeon driver.

The FPS I get with AMD R 520 card seems to be very low, if I run glxgears when compared to Intel Integrated graphics:

-HP-Laptop-15-bs0xx:~$ vblank_mode=0 glxgears
ATTENTION: default value of option vblank_mode overridden by environment.
40135 frames in 5.0 seconds = 8026.788 FPS
41018 frames in 5.0 seconds = 8203.442 FPS
40897 frames in 5.0 seconds = 8179.312 FPS
40758 frames in 5.0 seconds = 8151.432 FPS

With Radeon card, seems to be very slow. vblank_mode=0 also results in horizontal lines in glxgears.
HP-Laptop-15-bs0xx:~$ DRI_PRIME=1 vblank_mode=0 glxgears
ATTENTION: default value of option vblank_mode overridden by environment.
13545 frames in 5.0 seconds = 2708.850 FPS
13765 frames in 5.0 seconds = 2752.917 FPS
13785 frames in 5.0 seconds = 2756.820 FPS
13785 frames in 5.0 seconds = 2756.957 FPS

Is there something I can do to enable full potential of the dedicated card?

glxgears is not a benchmark

[Sebastien Bacher (seb128)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue you are reporting is an upstream one and it would be nice if somebody having it could send the bug to the developers of the software by following the instructions at https://wiki.ubuntu.com/Bugs/Upstream/GNOME. If you have done so, please tell us the number of the upstream bug (or the link), so we can add a bugwatch that will inform us about its status. Thanks in advance.

Thank you Timo and Sebastien for the acknowledgement. I have filed this bug to Gnome BTS and here is the link: https://bugzilla.gnome.org/show_bug.cgi?id=789570 . Please bear with me, but I'm confused whether this needs to be reported to the wayland upstream too? Do ask if I need to run anything more.

I installed Xonotic (3d game) benchmark to test both IGP and DGP. Here is the result:

with Intel HD 620 IGP:
HP-Laptop-15-bs0xx:~$ xonotic -benchmark demos/xonotic-0-8-d1 2>&1 | egrep -e '[0-9]+ frames'
356 frames 6.1346382 seconds 58.0311326 fps, one-second fps min/avg/max: 51 58 60 (12 seconds)

with AMD Radeon 520 2GB DDR3 DGP:
HP-Laptop-15-bs0xx:~$ DRI_PRIME=1 xonotic -benchmark demos/xonotic-0-8-d1 2>&1 | egrep -e '[0-9]+ frames'
356 frames 5.9962583 seconds 59.3703577 fps, one-second fps min/avg/max: 54 59 62 (12 seconds)

This is in 1080p mode. Is this looks normal for DGP? Thanks in advance.
