Not real sure what the status is on PS4 controllers in Steam.

As far as I can tell the controller is recognized generally. I'm using KDE, so I can plug in the PS4 controller and then go to the Joystick KCM and see the PS4 controller (/dev/input/js0). It also has a display where it shows what button / stick is used, and it seems to react the way you'd expect. However, Steam doesn't seem to recognize the gamepad at all. I think the only two games I've tried are Soda Girls and Wizard of Legend, and the gamepad doesn't work in either game. I've also tried going to Steam's Settings -> Controllers -> General Controller Settings and no controllers are detected.

I'm presently running Steam via flatpak (nstalled from this overlay) if that matters. Pretty much everything from that perspective is the default except for the fact I did an rbind mount in order to make my array available to steam:

Code:
/mnt/bigdata/gentoo_data/games -> /home/chris/.var/app/com.valvesoftware.Steam/Desktop/remote


Not really sure if there was any info worth pasting. Here is my kernel .config and emerge --info in case it helps.

Anyone had similar issues and resolved them?

Go steam ->settings ->controller -> general controller settings -> enable PS4 controller ( it doesnt need need to be detected just check that)
Some games dont see controller in linux (At least I saw in Bioshock Infinite game didnt see it at all)

I've just read that u were in that menu -> if u were in that menu and enabled - switch to Big Picture Mode and see if its working. Ofc connect controller via usb first and press playstation button.
I have only joysticks menu enabled in kernel, nothign more.

Is the controller's /dev/input/js* readable by your user?

You might need something like this in /etc/udev/rules.d/:
Code:
ENV{ID_INPUT_JOYSTICK}=="1", GROUP="plugdev", MODE="0660"


Once that's fixed, you'll have another problem...

@mir3x: Forgot to mention I enabled that already.

@Ant: Readable? Yes. I haven't made any changes to my udev config of which to speak, but the default permissions were 664 (ie; readable by everyone).

I also noticed js0 is writable by the "input" group. I added my user account to that group and restarted. Same behavior.

Doing some more searches, I'm starting to wonder if gamepads are actually supported within the flatpak method. Not finding many relevant results in general. I wanted to stick with the flatpak method to limit the amount of 32bit stuff in my general system, but I'll try installing Steam to my system briefly to see if I have any better luck with it.

Thanks for the input.

EDIT: No dice with installing it in the main system. The investigation continues!

/etc/X11/xorg.conf.d/40-libinput.conf is default one, in comment its written:
# Match on all types of devices but joysticks
There is no joysticks, 5 default entries.

Maybe you need to be in plugdev group or some other one...

Guess I should have done that when Ant suggested it! Added myself to plugdev, restarted and now Steam sees my PS4 controller. I could also play a game with it. Awesome!

I'm still not clear on what the specific issue was. After confirming plugdev worked, I removed myself from the group to see what the Steam output was. I get the same error about writing to /dev/uinput that you saw, but the file doesn't actually exist which seems to be the bigger problem so it may not even be relevant to the issue. Additionally, I could still use the PS4 controller while not in plugdev. Maybe it just needs plugdev for device detection.

This is at least in the copy of steam installed in my main system. I might try the flatpak again to see if it will work that way, and then I can uninstall the 32bit libs from my system. ;)

Thanks for the help!

Have fun.

Remember that you can play with controller in games which doesnt support controller. In Big picture mode u can press PS during game then go to settings and load some custom/users configs - or do it before starting game in Big Picture. Maybe in normal mode too, but not sure how to do that there.

/dev/uinput is used for Steam's "fake an xbox360 pad or other device so that lazy console/win9x ports work" feature, AFAIK. If your games work without it, congrats! You don't need it.

And yeah, the PS4 controller is a bit harder to set up than most - it creates at least half a dozen /dev/ entries, so simply having correct-looking perms on one isn't enough.
