Has anyone managed to get all three of these to play happily together? I just decided to plug an Intuos 3 into my new machine running 9.04 and whenever it is plugged in and I attempt to use Houdini the interface doesn't respond to mouse events. I can use the keyboard to enter commands and click on the tab menu entries but other than that I can't get any sort of input from either my mouse or tablet. Unplugging the tablet causes it to happily work again and I've had no problems with the tablet in a couple other test programs. I'm thinking it's a result of the fact that they have new hotplugging for Wacoms using hal but I can't really figure out any solution.

I'm having a bit better luck on PCLOS. First of all, when I plug in the Intuos3, I have to restart X for it to go into absolute mode. After that, everything is peachy (except for missing pressure support in Houdini that you have in Windows :(). Maybe it's worthwile comparing configs. This is default PCLOS, I haven't messed with it:

I doubt these are relevant but what the heck.

Thanks DaJuice for the info.

But I think that the new Ubuntu hotplugging system isn't the problem.

My xorg.conf is

Section "Monitor"
	Identifier	"Configured Monitor"
EndSection

Section "Screen"
	Identifier	"Default Screen"
	Monitor		"Configured Monitor"
	Device		"Configured Video Device"
	DefaultDepth	24
EndSection

Section "Module"
	Load	"glx"
EndSection

Section "Device"
	Identifier	"Configured Video Device"
	Driver	"nvidia"
	Option	"NoLogo"	"True"
EndSection

All the inputs drivers are controlled automatically in the fly.

It works great, but no luck with Houdni.

I have disabled the hotplugging system using 

Section "ServerFlags"
		Option "AutoAddDevices" "False"
EndSection

And I have modified the xorg.conf manually like in your files.

Again all works, wacom, etc ... but no luck with Houdini.

Conclusion, it seems the new hotplugging staff isn't the problem.

I am searching a solution for this too, but no luck.

I find this a strong probably cause

Wacom support is terribly broken in the latest Xorg thanks to xinput 1.5 and hal.....
except for missing pressure support in Houdini that you have in Windows

As for Windows, certain Wacom tablet drivers had missing 64-bit Wintab32.dll's. If you're on Windows 64-bit and your tablet has no pressure at all, then make sure you have the file C:\Windows\System32\WinTab32.dll (using a 64-bit app like Windows Explorer). Using the latest 10.0 daily build has fixes for occasional pressure lost under Windows.

Sorry Edward, that sentence came out wrong I guess. I meant that linux versions of Houdini lack pressure support (at least in my experience).
