[SOLVED] G200. Mouse pointer disappears

[JonathanEllis]

My mouse cursor becomes invisible when hovering over some graphically rich applications: most often Firefox when trying to drag maps in googlemaps.com. It also happens in XSane when I hover over the preview window to select a scan area.

I am running Ubuntu 8.04 (Hardy Heron) on a Dell Dimension 2400 with 1GB of RAM and an Intel Celeron 2.40GHz CPU. I have a Matrox MGA G200 PCI twin output graphics card. I am googling this problem at the moment but have not found anything yet.

Can you point me in the right direction to some info to help me fix this please?
Thanks for your consideration.

Regards,
Jonathan

Solved my problem using information found here http://forums.debian.net/viewtopic.php? ... c&start=15

I edited /etc/X11/xorg.conf as follows

Added this line to the "Device" section

Code: Select all

Option "HWCursor" "off"

In my case I added this to both Device sections as the G200 needs two Device sections (one for each output) as each output appears as a separate device.

Added this line to the mouse section

Code: Select all

Option "CorePointer" "true"

Actually most of this line was already there; I just added the "true" option. I don't know whether this was strictly necessary but I don't care: it's working!

Hope this helps someone.
