Failed to create direct3d device error message after enabling galliumnine about wine-nine-standalone

yes it requires mesa and a compatible gallium driver, of which nouveau is one.
That's documented here:

• https://github.com/iXit/wine-nine-standalone/wiki/Interoperability
• https://github.com/iXit/wine-nine-standalone/blob/master/README.rst
• https://github.com/iXit/Mesa-3D
• https://github.com/iXit/Mesa-3D/wiki
• all packages advertised in https://github.com/iXit/wine-nine-standalone/blob/master/README.rst
  ...

If proton ship gallium nine and doesn't depend on mesa, that's a proton bug.

I'm looking into mesa. I was not aware of it, does not having it explain my issue?

[siro20]

Please provide additional information:

• GPU in use
• mesa version
• console output of the game showing the error
• the games name not working

so to answer you :

• nvidia gtx 760
• mesa version is where I failed. all of the gallium-nine multiverse lacks documentation on this. nowhere was I made aware that I needed mesa for this. in fact I'm still not sure that I do.
  I had to, through trial and error figure out that for some reason when you install the inferior "Nouveau" driver you then get mesa.

here were my outputs with different drivers:
with "418" :

$ glxinfo | grep "OpenGL version"
OpenGL version string: 4.6.0 NVIDIA 418.56

with "340" :

$ glxinfo | grep "OpenGL version"
OpenGL version string: 4.4.0 NVIDIA 340.107

with the two above, I get "Failed to create direct3d device" "perhaps missing graphics driver"

with "Nouveau" (no longer preinstalled with ubuntu 19.04 nvidia 418 comes stock instead) :

$ glxinfo | grep "OpenGL version"
OpenGL version string: 4.3 (Compatibility Profile) Mesa 19.0.2

and the game runs basically as a backscreen, so broken beyond use, but when you run the commands I typed above + this (although I'm pretty sure the ppa is useless on ubuntu 19.04 since mesa is supposed to be stock) the game runs flawlessly.

• when the the game wasn't running I couldn't have opened it's console
• 9240 : supreme commander forged alliance.

I guess it's solved now though I would like a canonical answer for good : "is Nouveau required to benefit from gallium-nine?"
