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 (-: .

I meant "can not" not "can"...

In my case, using apt with the official PPA solved all drivers issues for the same latest version that is offered by snap.

First, I've removed the game from snap to prevent any conflicts.

sudo snap remove 0ad

Then, added the offical PPA repository, re-updated apt to recognize it and install:

sudo add-apt-repository ppa:wfg/0ad
sudo apt update
sudo apt install 0ad

Adding the PPA installs the latest alpha (currently, alpha 26)
