I recently purchased the game and downloaded the Linux version.
I know it's a "bonus" feature, but I was wondering if there are any additional steps I could take to ensure that this feature could work on my machine? I have tried
chmod a+r /dev/input/by-id/*event-mouse
On my Ubuntu 8.10 machine, but I get no mouse support at all when I set the config value to "true"

Officially this is an unsupported feature (so tsk! tsk! for asking about it in the Support forum instead of Mods&Hacks!) but you could try and have a look at the log file in $HOME/.WorldOfGoo/WorldOfGoo.log. If ManyMouse wasn't able to find any mice, it should be reported there.

I'm guessing this thread is about using multiple mice at once. IIRC it shouldn't be possible 'till Multi-pointer X goes into upstream X.

So it's detecting mice! Though I only had one mouse plugged in at the time. Maybe it's detecting 'mouse' devices that are sending it the wrong signals?

That's entirely possible...

I think every xxx-event-mouse device corresponds with a mouse in the game, so you may have to go through a little trial and error to figure out which devices work for you, and make the non-working ones unreadable to avoid them being used. Note that these devices may be created when you plug the mouse in, so you will have to do the chmod thing after you have plugged in the mice you want to use.

I admit, it's a bit of work to figure it all out, which is why it's not an officially supported feature.  ;)

Well I'm certain I've narrowed it down so it's only able to read the devices that are actually there... but it's still not giving me any mouse movement in the game.

Ah well. I guess it wasn't to be. :'(

Hi,

try editing your xorg.conf:

sudo nano /etc/X11/xorg.conf

Search for 'Section "InputDevice"' and be sure it's the InputDevice for your Mouse, not for your keyboard.
In this section, add:

    Option        "Protocol" "auto"<br />    Option        "Device" "/dev/input/mice"

If you have already edited the config.txt of WoG, restart your X-Server, give access to read the devices to your user and World of Goo should work with more than one mouse.

best regards
Malla

maybe a silly question:
should there be two independent mouse pointers in the game then? or still one that can, be moved by all pointing devices..?

When the game uses multiple mice, each mouse/player controls a separate cursor.
