I've just bought a new bluetooth mouse (Thinkpad bluetooth mouse). I'm able to connect it and it works but it lags and jumps (the cursor doesn't move smoothly as it should). At first I thought it was a hardware issue (batteries), but I tried it on Windows (running dualboot) and on Widndows it worked without any lags. The mouse is close to the laptop (5-15cm). My laptop is Lenovo Thinkpad Edge E531. I'm running Ubuntu 14.04. Do anybody know where should the problem be? Thanks forward.
dmesg
still claims loading the driver has failed the mouse somewhat works now. - If you have installed Blueman try uninstalling it. Some users claimed that to fix their issues.
