I have the amd 6700 gpu. When i run lutris in the terminal it cant find vulkaninfo or fluidsynth
IIRC you need to install vulkan both for 32 and 64 bits at least for some Lutris stuff, so it might be a good start to verify that you have that.
On my system:
/usr/bin/vulkaninfo is owned by package vulkan-tools
/usr/lib64/libfluidsynth.so.3 is owned by fluidsynth-libs
I don’t have the 32-bit version of either of those packages though, so that wasn’t necessary for the games I’ve played at least. Can’t remember if I installed them manually or if I got them through some metapackage.
I installed those, but i get theme parsing error: gtk-dark.css:6610:68: invalid name of pseudo-class when running lutris and it wont launch
Most likely that’s a theme issue. Close Lutris, change back to the default Adwaita theme and try again.
