Greetings,
This is for Mandriva 2006 - kernel 2.6.12 Toshiba R15 tablet.
first of all, added the following to /etc/X11/xorg.conf
Section "InputDevice"
Driver "wacom"
Identifier "Waccursor"
Option "Device" "/dev/ttyS0"
Option "Mode" "Absolute"
Option "Type" "cursor"
EndSection
Section "InputDevice"
Driver "wacom"
Identifier "Wacstylus"
Option "Device" "/dev/ttyS0"
Option "Type" "stylus"
EndSection
Section "InputDevice"
Driver "wacom"
Identifier "Waceraser"
Option "Device" "/dev/ttyS0"
Option "Type" "eraser"
EndSection
then, after some digging, I found the following setserial line worked:
/bin/setserial /dev/ttyS0 port 0x338 autoconfig
And I had pen motion - Yay!
But all was not well. It seems with the Mandriva-supplied wacom_drv.so
that the x and y are multiplied by 2 (or about) so that when the pen
is in the middle of the screen, the cursor is at the bottom right corner.
Yuck. I downloaded the package from LinuxWacom,
and renamed the Mandriva driver as follows:
/usr/X11R6/lib/modules/input/wacom_drv.so.ORIGINAL
then moved the LinuxWacom version of the driver to
/usr/X11R6/lib/modules/input/
Success. Now to get it working from boot.
The LinuxWacom Howto suggests putting the setserial line in:
/etc/rc.d/rc.local
This only sort of works - on Mandriva, if you are using the graphical
login, X, and the login are already running by the time /etc/rc.d/rc.local
runs. Not a big problem, but an annoyance - you have to remember to
restart X at the login screen, or X won't pick up on your pen port.
Here's what's better:
Since Mandriva seems to want to stick all the rc stuff in /etc/rc.d
(or, for some scripts, /etc/init.d) and symlink from there, and, since the
/etc/rc.sysinit, which is symlinked to /etc/rc.d/rc.sysinit has the
following code in it:
# Initialize the serial ports.
if [ -f /etc/rc.serial ]; then
. /etc/rc.serial
fi
what I did was:
echo '/bin/setserial /dev/ttyS0 port 0x338 autoconfig' >
/etc/rc.d/rc.serial
note: maybe to do this the "Mandriva Way" I should have put this in
/etc/init.d ?...
chmod 755 /etc/rc.d/rc.serial
ln -s /etc/rc.d/rc.serial /etc/rc.serial
then I removed the setserial line I had put in /etc/rc.d/rc.local
(although it probably did no harm, I just like to clean up)
The pen now works on the screen without having to restart the
X-server at the login prompt. Ta-da.
Now, if Mandriva would only quit blowing away the LinuxWacom
driver with their own broken one every time there's an X upgrade...
grrrr.
Cheers,
Chris
