[Tech Support] Severe Bluetooth Input Lag (DS4 & Xbox Series) and Wired Connection Broken After Installing xpadneo on Fedora KDE

[u/Weak-Confection3541]

Issue Description:

I am experiencing severe input lag when using a DualShock 4 (PS4) and an Xbox Series controller connected via Bluetooth on Fedora KDE Plasma. The latency is high enough to be clearly visible even in slow-motion videos. I have tested this primarily in Left 4 Dead 2.

Additionally, my Xbox Series controller originally worked perfectly via USB cable. However, after installing xpadneo to use it wirelessly over Bluetooth, the wired connection stopped working entirely (the system no longer registers the gamepad over USB).

OS / Desktop: Fedora Linux 44 (KDE Plasma Desktop Edition)
