5.4 - Restart X

Finally, restart X. You may wish to do this from runlevel 3 for testing purposes.

[root@ayukawa root]# init 3
...processes starting and stopping...
[root@ayukawa root]# startx
If the X server dies, you can always back-out the changes to the XF86Config or xorg.conf file and try again. But first, look at the X log file (XFree86.0.log for XFree86 and Xorg.0.log for Xorg) for clues. You might want to do this even if everything works correctly. When things are running right, the following lines appear in my log file.
[root@ayukawa root]# grep -i wacom /var/log/XFree86.0.log
(II) LoadModule: "wacom"
(II) Loading /usr/X11R6/lib/modules/input/wacom_drv.o
(II) Module wacom: vendor="The XFree86 Project"
(II) Wacom driver level: 47-0.9.5 $
(II) XINPUT: Adding extended input device "eraser" (type: Wacom Eraser)
(II) XINPUT: Adding extended input device "stylus" (type: Wacom Stylus)
(II) XINPUT: Adding extended input device "cursor" (type: Wacom Cursor)
(==) Wacom Kernel Input device name: "Wacom Intuos2 12x12"
(==) Wacom tablet maximum X=30480 maximum Y=30480 X resolution=0 Y resolution=0
(==) Wacom Cursor top X=0 top Y=0 bottom X=30480 bottom Y=30480
(==) Wacom Stylus top X=0 top Y=0 bottom X=30480 bottom Y=30480
(==) Wacom Eraser top X=0 top Y=0 bottom X=30480 bottom Y=30480

First things first, you should lift the mouse off the tablet and place it back down. This seems to help reset things internally. When you replace the mouse, the cursor should jump to that portion of the screen. If everything is working correctly, the mouse should work in absolute mode with the four corners of the tablet corresponding with the four corners of the screen. If the cursor stops short of an edge, then the kernel driver limits are probably incorrect. Please let me know so that I can update the driver.

Next, remove the mouse and try using the eraser end of the stylus. Hovering over the surface of the tablet should move the cursor. Touching the eraser tip to the surface should generate a click. If you invert the pen and use the stylus tip, you should get a similar result. If the pen tip generates spurious touch events, you will need to increase the threshold value in the InputDevice section. Wacdump is useful for determining the appropriate value.

Lastly, if you would like more logging, the parameter "DebugLevel" (for individual tools) and "CommonDBG" (for all tools associated with the same tablet) can be set to values between 1 and 12, with 12 being way too much, and 1 being fairly useful.

If X server failed to start and you are running the prebuilt wacom_drv.(s)o, you may have to go back to Configuring the Package page to build the driver on your system.
