After installing Ubuntu 14.04, my cursor is disappearing on my laptop (Dell inspiron 5110 with nvidia gforce GPU). I tried several answers, but the problem is not solved.
I tried this:
Open System Settings > Displays. In the Displays window, you will see an Unknown monitor. Click it and disable it.
and this answer:
gsettings set org.gnome.settings-daemon.plugins.cursor active false
Both solutions did not work. Do you have any suggestions?
