I recently installed gnome3 on my Ubuntu partition (on a suspicion that unity is memory leaking) and now my mouse has disappeared from both the login screen and after logged in. I used these instructions to install it on my Ubuntu 13.10 this morning so it should be the most recent version I think. Does anyone know what causes this or how to fix it?

Try this:

  • open a terminal an run gsettings set org.gnome.settings-daemon.plugins.cursor active false OR
  • run dconf-editor and navigate to org.gnome.settings-daemon.plugins.cursor and set the schema active to false.

  • Open System Settings > Displays by pressing window key and search for system settings in dash.

  • In the Displays window, you will see an Unknown monitor. Click it and disable it

If you are using an old NVIDIA card try installing 

apt-get install nvidia-common

Important:
Don't run nvidia-config and don't create any xorg.conf file now!

Then reboot

apt-get install nvidia-173

reboot

I don't know if there has to be several reboots, but the first time I tried it without installing nvidia-common first and this messed up with my resolution for my LCD monitor
