Shaking cursor on a bluetooth mouse

Support
1

Good afternoon everyone, how are you? I would like to ask for help with an issue I’ve been experiencing and it’s driving me crazy! I bought a Bluetooth mouse and keyboard from DELL about three months ago. The first time I used it, I thought it was okay, but after a while, I noticed that I was missing the buttons when trying to click, for example, the close tab button on the browser. The precision level of the mouse is very poor on Linux, I thought this could be a physical problem but I have a Windows laptop here and it works fine. I’ve attached an image below to illustrate how poor the precision is.

I have no idea what could be causing this problem. I’ve done several searches and I saw that it could be the battery, so I replaced the battery and the problem persists. I also saw something related to the boot not loading the drivers correctly, so I set the BIOS to default and disabled fast boot. I installed the manjaro-bluetooth package to see if it would solve the problem, but it didn’t help. I tried to enable or disable mouse acceleration, but also without success. I also tried to update or downgrade kernel (from 6.6 LTS to 5.10 LTS) Any tips on what I can do? I really appreciate any directions that I could take here.

this cambridge-bluetooth-adapter troubles often.
you can try to install

pamac install bluez-hid2hci

reboot and check.
there are also some settings like autoenable etc… that you can enable in
etc/bluetooth/main.conf. check the internet for the individual functions of this config-file.

p.s.: i had a similar usb-bluetooth adapter (hama) and it was a pain. it’s worth to replace this one with a more actual and accurate stick. this adapters aren’t so expensive but safe a lot of anger.

This package is installed already :smiling_face_with_tear:

bluez-hid2hci  5.72-2 [Installed]                                                                            extra
    Put HID proxying bluetooth HCI's into HCI mode

check /etc/mkinitcpio.conf for

#MODULES=(usbhid xhci...

uncomment it to

MODULES=(usbhid xhci_hcd....

run

sudo mkinitcpio -P
sudo update-grub

reboot, check and report please

Hey Olli, thanks for your answer. I did this but it didn’t help. Have been using for five days with no improvement of the shaking cursor.

But today things got a little worse, sometimes my mouse gets veeeeery slow for like 6 seconds and get back to normal, sometimes when I try to write a lettttttttttttttttttttttttttttter it repeats like this for like 1 or 2 seconds. The keyboard and the mouse share the same dongle. It’s a Dell KM5221W
