When using my Sony Vaio laptop, my mouse touchpad sometimes starts acting up. When on Ubuntu, I simply type these 2 commands in terminal to restart my mouse.
sudo modprobe -r psmouse
sudo modprobe psmouse
This solves the issue in Ubuntu. However, I couldn't find similar commands for Windows 10. My only resort is restarting Windows 10. I have tried updating the driver. It says that that my mouse driver is the latest driver. Fn key + Mouse disable/enable does nothing on Windows 10. However, Fn key + Mouse does work on Ubuntu.
