## 7. XFree FAQ - Problems And Questions

## 7.1 Gnome and Gimp only work like a usual mouse, without pressure and tilt. Gimp Input Devices Dialog shows "No Input Devices"

It seems that you have not compiled your gtk with XInput-support. Please rebuild gtk and use ./configure --with-xinput=xfree for building the Makefile. Then do a make && make install. Then rebuild your gimp so that it uses this extendet gtk.

## 7.2 Is the wheel of the mouse (cursor) supported ?

Yes, it generates button 4 and button 5 events.

## 7.3 How can I find out the intuos Serial Num of my tool ?

read the section about Serial_Num

## 7.4 How do I change the action of each button of my tool?

Read the section about buttons.

## 7.5 How can I use the intuos/artpad/ultrapad macro area ?

You can not use the intuos macro area, sorry.
Only Artpad / Ultrapad Macro stripes work. Read the section about Gimp Keys.

## 7.6 Is it possible to define multiple active areas on the same tablet ?

Yes, read the section about the Top... Statements

## 7.7 Can I use more than one tablet at the same time ?

Yes, read the 'Port and Device' section

## 7.8 The Wacom Driver eats my CPU Time. Any Hint ?

This mostly happes under the following condition:
AllowMouseOpenFail was specified and the device is set to /dev/null. Set the device to a nonexisting file instead, for example /dev/fake, and you will get back your CPU time. See the examples for this under the 'Port and Device' section.

Another reason may be that there were too many interrupts produced.
I was told, that hdparm -u1 /dev/hdx (replace x with your drive letter) may help.

## 7.9 The Cursor 'dances' around

Most Graphire's are known to be weak for that, intuos seems to be better but still not perfect. This seems to be a hardware problem.
Possible Solutions:

- Put your tablet as far as possible away from all emitting devices like monitors, printers, computers, AC-adapters.
- Use a modified driver with a filter algorythm. Many of them are in development right now but none of them seem to be the cruncher.
- If using an IDE drive, try hdparm -u1 /dev/hdx (replace x with your drive letter)
