DS4 controller stopped working after update

ISSUE

With the latest stable version of Steam and also with the latest beta, my Sony DualShock 4 controllers are not detected anymore. They are connected via Bluetooth.

They already worked with an older version of Steam.

They work with many games outsides of Steam.

They work with SDL (sdl-jstest finds them and input works)

Controller model: CUH-ZCT2E



Also tried to set the following controller settings - without success:

export SDL_GAMECONTROLLERCONFIG='050000004c050000cc09000000810000,PS4 Controller,a:b0,b:b1,back:b8,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:b10,leftshoulder:b4,leftstick:b11,lefttrigger:a2,leftx:a0,lefty:a1,rightshoulder:b5,rightstick:b12,righttrigger:a5,rightx:a3,righty:a4,start:b9,x:b3,y:b2,platform:Linux,'





OS

Ubuntu 18.10



STEPS

Go to Controller settings

RESULTS

No controllers found



EXPECTED

Controllers are detected and work
