..Im gonna try post "Just to confirm that if" as a fix for now.
....that did not work

My current fix is to keep a terminal window open and when the cursor disappears, I switch to the terminal, press enter and bingo, cursor.

I am using 9.10 with two displays. The primary display is my laptop LCD. The secondary display is my HD TV. They are both active at the same time. When I am using the secondary display, sometimes the mouse cursor disappears. To get it back, weirdly, I open a gnome-terminal and press the enter key, the cursor reappears. This is annoying. How can I prevent the cursor from disappearing?

It seems this happens when I leave the computer idle for a minute or two. On the primary display a blue box comes up showing the brightness of the display. This is when I guess it tries to dim the display because it thinks to save power or something.

Just executing gnome-power-preferences disappears my mouse cursor.

This is a Gateway Laptop MT6704 using i915

Im using a second USB keyboard and mouse. The secondary monitor is a Westinghouse SK-32H635S connected via VGA cable.

three things I noticed in dmesg?
[ 43.108738] i2c-adapter i2c-0: unable to read EDID block.

This is news to me...
/proc/acpi/video/GFX0$ cat ./DD03/info
device_id: 0x0320
type: DVI
known by bios: yes

If I knew there was DVI out I wouldnt be using VGA. I can attest, nowhere on the outside of this computer is there a place to connect a dvi cable. There is firewire and svideo.
