Cursor getting stuck in launcher

Question

It's a weird issue. The cursor gets stuck in place but still moves so that if I click I click on what I aimed to but the cursor is not where it should be. It only happens in the launcher. I tried this to no avail.

Answer 1

EDIT:

first do:

modprobe -r psmouse

modprobe psmouse

If it will not help, boot into grub (by holding shift) and perform RAM check.

another possible solution would be reinstalling drivers:

sudo apt-get --reinstall install xserver-xorg-input-mouse

Answer 2

1. Press Ctrl+Alt+F1 when you arrive at the login screen.

2. Run sudo service lightdm stop to stop the X server.

3. Install NVidia-370:

   sudo add-apt-repository ppa:graphics-drivers/ppa
   sudo apt-get update
   sudo apt-get install nvidia-370 nvidia-settings
   

4. Add blacklist nouveau to bottom of file /etc/modprobe.d/blacklist.conf.

5. Run sudo update-initramfs -u.

6. Run sudo reboot to restart.

Your mouse should have now appeared correctly! Please reply stating if this solution worked or not.
