Linux Wacom Project HOWTO
8.0 - GUI-Based (tcl/tk) Wacom Control Panel(wacomcpl)
wacomcpl is a simple graphic Wacom driver configuration tool. It changes the pressure sensitivity, click threshold, button functions, cursor mode, speed, mapping, etc. without having to manually modify XF86Config/xorg.conf file. For Cintiq and Tablet PC users, it is also a tool to calibrate the tablet. wacomcpl should be launched when you login as yourself since .xinitrc (or .xsession), a file under your home directory, will be updated locally each time you run wacomcpl. The .xinitrc (or .xsession) stores the preferences you selected through wacomcpl for your next login. The goal is to give each user a chance to use his/her own preference on a shared system.
If you want all users on one system to share some settings, you can copy those lines started with xsetwacom in ~/.xinitrc (or ~/.xsession) to /etc/X11/xinit/xinitrc (/etc/X11/xinit/Xsession).
If your system doesn't execute .xinitrc (or .xsession) at login, each time after exiting from wacomcpl, you will need to copy those xsetwacom lines in .xinitrc (or .xsession) to a startup script (.bashrc, .cshrc, .profile, etc.) that your system launches. You can also modify wacomcpl-exec to automate this step.
However, it is reported that there are older systems on which can not run wacomcpl due to some XFree86 interface error. The workaround is to add the configuration options to your X config file, refer to Configuring X11 page for details.
If wacom_drv.(s)o was running while installing wacomcpl, wacomcpl can be launched immediately after make install and exit.
If wacom_drv.(s)o is installed by the same make install as wacomcpl is, restarting X server is required to use the newly built wacom_drv.(s)o. We strongly recommand to build and install the wacom_drv.(s)o and wacomcpl from the same release package since the out of sync wacom_drv.(s)o and wacomcpl may crash your X server.
