Wacom not working under Linux

Hello,
I know this has been discussed before but the solutions mentioned in all other posts didn’t work for me.
I have an old wacom volito, but which works very well in MyPaint, Gimp, Inkscape and others.
In Synfig movint the styles over the tablet moves the cursor and the coordinates are updated correctly. Operations equivalent to clicking, hovewer, don’t work at all.
What can I do? Also, I don’t know where is the config file for synfig.

Host/Kernel/OS “desktop-aptosid” running Linux 3.1-4.slh.2-aptosid-amd64 x86_64 [ aptosid 2011-01 Γῆρας - kde-lite - (201102051540) ]

Hi),
can you list here the devices found when you run the Input Devices Dialogue (ToolBox->File->Input Devices)?
This is what I get when I plug my wacom graphire and after that I run Synfig Studio.

This is what I’ve got. Hovewer, enabling them does not work :frowning:

You have to disable all them and then enable just ‘Wacom Volito stylus’ set to screen.
