When I first paired my DualShock 4 wireless gamepad all features were working, I could use it as a gamepad in all applications and the gamepad's trackpad was working as a mouse.
I was having some connection issues with my computer's builtin Bluetooth hardware, so I decided to try a USB dongle. In order to use the dongle, I downloaded the Bluetooth manager from GNOME software since I couldn't choose which Bluetooth device to use in the GNOME's Bluetooth settings.
But when I paired using the manager, the trackpad stopped working. I decided to go back to the builtin GNOME Bluetooth manager, so I uninstalled the manager from GNOME software.
Unfortunately, the trackpad is still not working with GNOME's builtin Bluetooth manager. What might be causing this problem?
