I installed the Manjaro KDE version (latest stable and updates) about a week or two ago. Today I wanted to play some Euro Truck Simulator 2 and noticed some strange behaviour when pressing a certain button on my Logitech G29 steering wheel. The button I pressed was the RSB button which corresponds with the BTN_BASE3 according to evdev (output of python test below). When I press this button two this happen, the volume goes down and the mouse moves to the right. (also when not in-game)
device /dev/input/by-id/usb-Logitech_G920_Driving_Force_Racing_Wheel_for_Xbox_One_000064a864939969-event-joystick, name "Logitech G920 Driving Force Racing Wheel", phys "usb-0000:00:14.0-1/input0" key event at 1564329137.862715, 296 (BTN_BASE3), down key event at 1564329138.182698, 296 (BTN_BASE3), up
Is there anyone who has the same or has a solution to solve this? I already looked into the mouse moving thing by trying to disable it in Xorg as described in the Arch forum. This however did not help as Xorg refused to start after.
On another note I do not have the xf86-input-joystick package installed and most forum posts ask to remove this package.
I am wondering if this is a KDE thing since also the volume is turned down when pressing the button and I have not experienced this in the Manjaro XFCE edition.
