Installation and usage

Make sure ~/.steam/root exists and is the main Steam folder (e.g.: it contains steamapps, userdata folder). That directory should be linking back to the real steam folder :

• on debian based distros like Ubuntu or Mint ~/.steam/root seems to link back to ~/.steam
• on something like Arch ~/.steam/root points to ~/.local/share/Steam

$ mkdir -p ~/.steam/root/compatibilitytools.d
$ tar xf Proton_3.16-6_Gallium_Nine_Extras_0.1.2.tar.xz -C ~/.steam/root/compatibilitytools.d

Select Proton 3.16-6 Gallium Nine Extras 0.1.2 in the SteamPlay tab.

You may need to fill in the proper paths to the d3dadapter9.so.1 for your system. Execute the following line in your terminal :

$ echo PROTON_GALLIUM_NINE_MODULEPATH=\"$(find /usr \( -type f -o -type l \) -name d3dadapter9.so.1 -exec sh -c 'file -L "{}" | grep -q "ELF 32-bit"' \; -print -quit 2>/dev/null):$(find /usr \( -type f -o -type l \) -name d3dadapter9.so.1 -exec sh -c 'file -L "{}" | grep -q "ELF 64-bit"' \; -print -quit 2>/dev/null)\"

And you should get a line like PROTON_GALLIUM_NINE_MODULEPATH="/usr/lib32/d3d/d3dadapter9.so.1:/usr/lib/d3d/d3dadapter9.so.1" back that you can paste into the launch options directly like :

PROTON_GALLIUM_NINE_MODULEPATH="/usr/lib32/d3d/d3dadapter9.so.1:/usr/lib/d3d/d3dadapter9.so.1" PROTON_USE_GALLIUM_NINE=1 %command%

PROTON_USE_GALLIUM_NINE=1 will enable Gallium Nine.

You can enable this globally as well, you just need to rename user_settings.sample.py to user_settings.py and uncomment the appropriate gallium nine lines.
