Turn off hardware cursor Lubuntu 13.04

[user_of_gnomes]

I'm trying to execute the following instructions to see if I can figure out why the mouse cursor is missing from my Lubuntu installation (With an Nvidia NV10 videocard)

Open a terminal and type:

sudo gedit /etc/X11/xorg.conf

Locate the Section "Device" section and add the following line:

Option "HWCursor" "off"

So it looks similar to the following (your Section "Device" section may vary)

    Section "Device"
    Identifier "nVidia Corporation C51PV [GeForce 6150]"
    Driver "nv"
    BusID "0:5:0"
    Option "HWCursor" "off"
    EndSection

but there does not seem to be a /etc/X11/xorg.conf

What do I do?

The bug is reproducable with NV10, NV11 and NV17 AGP videocards. Mouse pointer appears with NV34 videocard.
