Xbox controller

[Azcledel]

I have been using the same Xbox controller on steam for probably 5 months and its worked. Today I noticed my L2 button is not working in Fallout 4 and other steam games. Every other button works fine. But when I use it for my non steam games through Epic, L2 works completely fine. If anyone could help that'd be great

I'm thinking an option would be to disable Xbox Configuration Support/Steam Input & avoid the issue if it's what I think it is. For a (potential) fix, check if the trigger is mapped in the base mapping:
- Steam > Settings > Controller > General Controller Settings
- Select the Xbox controller > Define Layout
- Map the trigger if need be > Save > No, thanks

Re-defining a layout is currently a bit buggy. Once you've mapped the trigger (if required) and saved the layout, choose Define Layout again and see if the change has persisted - if not, retry the process. Things can also be done manually in a config file if need be.

If the left trigger had been mapped (would be Axis 2) you could check things in new Big Picture mode. It has a new test screen where it'll display the trigger's reading.
BPM > Menu > Settings > Controller > 'Test Device Inputs' Begin Test
