Portal. Problem with gamepad. Linux.

[Occisor]

The game blue portal on the left, orange on the right. But on the gamepad (xbox360): "LT" - orange, "RT" - blue. Change the settings on the contrary, everything is fine, but after restarting the game settings are saved and you have to change again.
In the file .../SteamApps/common/Portal/portal/cfg/config.cfg changed values
bind "L_TRIGGER" "+attack2"
bind "R_TRIGGER" "+attack"
to other values
bind "L_TRIGGER" "+attack"
bind "R_TRIGGER" "+attack2"
But after the start of the game, they again become so
bind "L_TRIGGER" "+attack2"
bind "R_TRIGGER" "+attack"
Why?

That was the default config for the Xbox version. It automatically changes back because it is returning to the default 360 controls.

How to do so LT = blue portal, RT = orange portal, at all times?

[Occisor]

Solved the problem as follows.
Go to the folder ../SteamApps/common/Portal/portal/cfg
Create a file 360controller-linux.cfg
With the following content:

joy_name "Game controller"

bind "A_BUTTON" "+jump"
bind "B_BUTTON" "toggle_duck"
bind "X_BUTTON" "+use"
bind "Y_BUTTON" "togglescores"

bind "START" "pause"

bind "STICK1" "voicemenu 0 0"
bind "STICK2" "+duck"

bind "L_TRIGGER" "+attack"
bind "R_TRIGGER" "+attack2"
