I'll try to be as brief and as concise as possible. I've bought a nice gamepad, here is what dmesg reports:

Non-steam games on linux work without problems with the controller, like emulators, X-Moto etc. Steam and games under it are the issue.
OK, so far so good. I started steam, went on to configure the gamepad. Here's where the trouble begins. It asks me to assign all the buttons, and I do, one by one. But when I get to the one where it's the simple up/down/left/right, I can only assign two of them, and they are marked Axis 0 and Axis 1.
For example, I set UP = Axis 0 (I simply press it on the gamepad, to be clear), LEFT = Axis 1, DOWN = (here I press the down button of course) but it's assigned as Axis 0, and the UP is overwritten!! The same goes for setting the RIGHT, the LEFT gets overwritten. Of course, the game(s) are unplayable.
I took a look at what symlink is in /dev/input/by-id... on /dev/input/event15:

The values received from the joystick ARE NOT the same for left/right for example.
OK, moving on, I searched the files that were modified last, and this is what I found:
~/.local/share/Steam/config/config.vdf:
As you can see, this is a standard SDL mapping of some sort, but some of the controls are simply not entered. So it goes, GUID, profile_name, PHYSICAL_KEY:MAPPING. Out of frustration after trying 5 or 6 times, I simply saved this as "jjj". Anyway, I googled the GUID to see if I can find anything and I stumble upon this: https://github.com/gabomdq/SDL_GameControllerDB/blob/master/gamecontrollerdb.txt
If you search for the big GUID, you'll find my GreenAsia controller. I think this is mapped as it should be mapped.
So, after "jjj', I inserted: a:b2,b:b1,y:b0[...]
Started up steam and the game again, no effect. I take a look at the file again, I see it's been overwritten with the same half-missing config. So I make the file read only, perms 444, and it's not overwritten anymore, but unfortunately, still the same. I can only move right, and I can only go up (or jump in games). The ones on the left, the A, B, C, D seem to be working fine. Obviously it didn't do the trick, I'm unfamiliar with SDL and its inner workings to know exactly how is this communication done in accordance with Steam etc.
Any ideas? How can I be more verbose with debugging info. I feel this is something minor to fix. This is very frustrating. :)
