Weirdly enough, I could never get my DS4/PS4 controller working on Linux, at least through Bluetooth. The device never shows up in the device list. My Xbox Series X and Xbox One X controllers work perfectly with Bluetooth thanks to xpadneo, and I can use my DS4/PS4 controller wired with or without ds4drv, but I just can’t get it to work wirelessly.
That is strange. It works great for me. All I had to do was pair it.
I have read that some computers have bluetooth modules that don’t play well with it, though. Maybe you have one of those, or an old kernel?
I’m on Ubuntu 22.04, kernel 6.5.0-41-generic so it shouldn’t be that. Maybe my Bluetooth adapter isn’t that great but it’s a TP-Link UB400 so it’s not exactly a low quality Bluetooth adapter either.
I think that kernel version should handle it, as long as the hid-sony or hid-playstation module is being loaded. (Some 6.7 and early 6.8 kernels had a relevant bug, though.)
It’s hard to say regarding the bluetooth adapter. The branding and price don’t matter; my cheap old no-name dongle worked great. It’s really about whether the parts used inside happen to play well with the other device.
Another thought: Is it possible you have the old version of the DS4, rather than the DS4 v2? If I remember correctly, the light bar is visible through the touchpad only on the v2.
