sudo echo wacom >> /etc/modules
Code: Select all
grep -i 'wacom' /var/log/syslog
Code: Select all

Next is to make it usable:
Code: Select all
inputattach --w8001 /dev/ttyS4

sudo gedit /etc/rc.local
Code: Select all
#!/bin/sh -e
#
# rc.local

# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
inputattach --w8001 /dev/ttyS4
exit 0
The new window manager makes it really nifty to use. Great work Mint development team, and thank you!
