<P>

<H2><A NAME="ss7.1">7.1 Gnome and Gimp only work like a usual mouse, without pressure and tilt.</A>
Gimp Input Devices Dialog shows &quot;No Input Devices&quot;</H2>
<P>It seems that you have not compiled your gtk with XInput-support.
Please rebuild gtk and use <EM>./configure --with-xinput=xfree</EM> for building the Makefile. Then do a <EM>make &amp;&amp; make install</EM>. Then rebuild your gimp
so that it uses this extendet gtk.
<P>
<H2><A NAME="ss7.2">7.2 Is the wheel of the mouse (cursor) supported ?</A>
</H2>
<P>Yes, it generates button 4 and button 5 events.
<P>
<H2><A NAME="ss7.3">7.3 How can I find out the intuos Serial Num of my tool ?</A>
</H2>
<P>read the section about
<A HREF="Wacom-Tablet-HOWTO-5.html#_Toc465765712">Serial_Num</A><P>
<H2><A NAME="ss7.4">7.4 How do I change the action of each button of my tool?</A>
</H2>
<P>Read the section about
<A HREF="Wacom-Tablet-HOWTO-6.html#_Toc465765724">buttons</A>.
<P>
<H2><A NAME="ss7.5">7.5 How can I use the intuos/artpad/ultrapad macro area ?</A>
</H2>
<P>You can not use the intuos macro area, sorry. <BR>
Only Artpad / Ultrapad Macro stripes work.
Read the section about
<A HREF="Wacom-Tablet-HOWTO-6.html#_macrokeys">Gimp Keys</A>.
<P>
<H2><A NAME="ss7.6">7.6 Is it possible to define multiple active areas on the same tablet ?</A>
</H2>
<P>Yes, read the section about the
<A HREF="Wacom-Tablet-HOWTO-5.html#_Toc465765719">Top... Statements</A><P>
<H2><A NAME="ss7.7">7.7 Can I use more than one tablet at the same time ?</A>
</H2>
<P>Yes, read the
<A HREF="Wacom-Tablet-HOWTO-5.html#_Toc465765709">'Port and Device' section</A><P>
<H2><A NAME="ss7.8">7.8 The Wacom Driver eats my CPU Time. Any Hint ?</A>
</H2>
<P>This mostly happes under the following condition:<BR>
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
<A HREF="Wacom-Tablet-HOWTO-5.html#_Toc465765709">'Port and Device' section</A>.
<P>
<P>Another reason may be that there were too many interrupts produced.<BR>
I was told, that hdparm -u1 /dev/hdx (replace x with your drive letter) may help.
<P>
<H2><A NAME="ss7.9">7.9 The Cursor 'dances' around</A>
</H2>
<P>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.<BR>
Possible Solutions:
<P>
<UL>
<LI>Put your tablet as far as possible away from all emitting devices like
monitors, printers, computers, AC-adapters.</LI>
<LI>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.</LI>
<LI>If using an IDE drive, try hdparm -u1 /dev/hdx (replace x with your drive letter) </LI>
</UL>
