I've been trying to use a bluetooth keyboard in my Ubuntu 18.04 but at first I could only connect the keyboard itself but it wouldn't actually type anything. I've looked for solutions online and, oddly enough, installing the xserver-xorg-input-kbd package made the keyboard work... only in the login screen and terminal. After loggin in, nothing works anymore.
The laptop's original keyboard is still working (although some keys around the "W" key are starting to fail, hence why I'm using a BT keyboard) and I can also connect a USB keyboard with no problem. The only one that doesn't work is the Bluetooth one.
output when using xinput shows that the keyboard has been recognized(its id is 25):

Strangely enough, I also can capture key events normally when using evtest, but not when using xev. I think that might be a major clue.
I also did try using the HP Wireless Keyboard driver from JohnJohanssonChalmers (https://github.com/JohnJohanssonChalmers/hp_wireless_keyboard) but when I install it, the keyboard starts to send a lot of random input and repeating key strokes even if I don't even touch it.
