0ad uses llvmpipe graphics driver instead of amdgpu Radeon RX 6600

[thehiggsfield]

I just got a new computer with a Radeon RX 6600 and a Ryzen 9 5900x, running Ubuntu 22.

 

I have the snap version of 0ad installed (from ubuntu software center) and when I open 0ad I get the following warnings:

WARNING: You are using 'llvmpipe (LLVM 10.0.0, 128 bits)' graphics driver, expect very poor performance!

WARNING: If possible install a proper graphics driver for your hardware.

 

And the game only runs at 16 FPS on minimum settings, which is worse than my 5 year old laptop :-(.

 

When I run “lspci -k | grep -EA3 'VGA|3D|Display'” I get:

 

Subsystem: Sapphire Technology Limited Navi 23 [Radeon RX 6600/6600 XT/6600M]

Kernel driver in use: amdgpu

Kernel modules: amdgpu

 

which seems to indicate Linux/Ubuntu is using the correct graphics card and driver. In the Tomb Raider benchmark (Installed through steam) I get 270 FPS, and it runs cool as a cucumber, so I think it’s a snap/0ad issue and not with my system in general.

 

Any idea what’s going on?

I’m not using a VM or anything weird ;-)

 

UPDATE:
I tried doing an installation with a simple:
sudo apt-get install 0ad
With this installation, I don't get the warnings, I get frame rates of ~60 and it seems much smother so far.
So I think Stan is on to something with the snap theory.

PS:

As unrelated bonuses, when not installed as a snap, it seems I can finally run /usr/games/pyrogenesis, so I can package mods :-D, and the .desktop entry for 0 A. D. shows up, when I search for "0ad" (I don't have to search for "0 A. D.")

Hey,

Thanks for the report I'm pinging the snap maintainer @oSoMoN 

Maybe it's because of Adding OpenGL/GPU support to a snap - doc - snapcraft.io

That looks like a snap-specific problem indeed. Let's see if we can figure it out.

Can you run the game with a terminal running

journalctl -f | grep DEN

in parallel, then exit the game and share the output of that journalctl command here?

"journalctl -f | grep DEN" gave me:
Mai 21 15:11:42 [My Computer] audit[7070]: AVC apparmor="DENIED" operation="open" profile="snap.0ad.0ad" name="/etc/openal/alsoft.conf" pid=7070 comm="main" requested_mask="r" denied_mask="r" fsuid=1001 ouid=0

I have sanitized the output by replacing my computers name with "[My Computer]".

For good measure 0ad gave me this:

Where [~] is the path to my home folder.

I also stumpled uppon the file "/snap/0ad/current/usr/share/libdrm/amdgpu.ids", which seems to contain a list of graphics cards, where I can not find my graphics card.
No I idea if it's relevant, but just thought it would be worth mentioning (-: .
