Ubuntu 14.04. I like turn on numlock on autorun. I found this recommendation:
go to /usr/share/lightdm/lightdm.conf.d/50-unity-greeter.conf and add greeter-setup-script=/usr/bin/numlockx on
When I did it, after restart I've got: "The system is running in low-graphics mode". Any recommendation for this error not help me. But when I deleted "greeter-setup-script=/usr/bin/numlockx on" in /usr/share/lightdm/lightdm.conf.d/50-unity-greeter.conf all become ok! Why? do you know?
