Current Issues and Regressions

Notes

Touchscreen configuration

Step 1 - Install the "wacom-tools" and "setserial" packages using the following:

sudo apt-get install wacom-tools setserial 

If you're using 7.04, stop here! Restart X (or reboot) and the pen should be working as expected.

If you're using pre-7.04 Ubuntu, continue...

Step 2 - Run the following setserial command to set the device to the screen

sudo setserial /dev/ttyS0 port 0x338 irq 4 autoconfig 

NOTES:

• On 6.06 (Dapper) the device is /dev/ttyS4

• On 6.10 (Edgy) the device changed to /dev/ttyS0

Step 3 - Edit the "/etc/X11/xorg.conf" file and change every instance of "/dev/wacom" to "/dev/ttyS0" (or ttyS4 for 6.06)

Step 4 - Restart X (CTRL-ALT-BACKSPACE)

Finished - The pen should now work

Automatic Screen Rotation

Step 1 - Get the restricted NVIDIA drivers working

• Feisty - click the System menu, Administration, Restricted Drivers Manager

• pre-Feisty - lots of how-to entries in the forums

Step 2 - Edit XORG to add rotation

• edit the xorg.conf as per Step 3 of the touchscreen configuration section above

• find the Section "Device"

• between Section "Device" and EndSection add the following line (preferable nearer EndSection than the top)

Option          "RandRRotation" "on"

Step 3 - Restart X (CTRL-ALT-BACKSPACE)

Step 4 - Create the Rotate Script

• create a new file (suggestion: gedit)

• the following script has been copied from http://i-otto.blogspot.com/2006/09/toshiba-portg-m200-with-ubuntu.html

• all credit goes to the script's authors Patrick Coke and Tim Pope
• paste the following into your new file

#Author: Patrick Coke & Tim Pope
#
#
while xset q >/dev/null 2>&1; do
sleep 2 # Polling Interval, 2 seconds

lid="`cat /proc/acpi/button/lid/LID/state|awk '{print $2}'`"

# Looks to see if what orientation the screen is in (Normal or Left)
# and puts the orientation into the $orientation variable
orientation="`/usr/bin/X11/xrandr --query | /bin/grep 'Current rotation' | /usr/bin/awk '{print $4}'`"
dpms="`xset q|grep 'Monitor is'|awk '{print $3}'`"
if [ "$orientation" = "normal" -a "$lid" = "closed" -a "$dpms" = "On" ]; then
# Rotates screen orientation to the left
/usr/bin/X11/xrandr --orientation left
# Rotates the stylus cordinate plane
xsetwacom set "stylus" Rotate 2
elif [ "$orientation" = "left" -a "$lid" = "open" ]; then
# Rotates the screen back to normal
/usr/bin/X11/xrandr --orientation normal
# Rotates the stylus cordinate plane to normal
xsetwacom set "stylus" Rotate 0
fi
done

Step 5 - Save and Name the file appropriately

• save the new file in a safe place away from accidental deletes
• suggestion: /home/{user}/scripts/Rotate - replace {user} with your user account

Step 6 - Make the script executable

• open a terminal
• enter the following, making any necessary change to reflect the name and location of your script

chmod 777 /home/{user}/scripts/Rotate

Step 7 - Add the script to the startup

• Click System menu, Preferences, Sessions

• Click New on Startup Programs

• In the Name field, put anything you like (suggestion: Rotate)

• Click Browse and find the script (suggestion: /home/{user}/scripts/Rotate)

Step 8 - Logout and Log back in

Finished - Try rotating the screen

NOTES:

• The script above, whilst excellent, rotates the screen into portrait with the ports/exhaust on the left hand side - I prefer to have the ports/exhaust on the right hand side in portrait mode, as I'm right-handed - to do this, find/replace all occurances of left with right in the script and change the number at the end of the first line that starts xsetwacom to 1 not 2

• I prefer to manually control rotation in all four orientations with a set of scripts and a taskbar icon - I'll try and write-up the manual control version at a later date (02/07/2007)

Suspend to RAM on edgy

If your laptop doesn't suspend to ram (comes back immediately) do this:

    sudo apt-get install powersaved

• (possibly add GUI for it, kpowersave or other)
• Edit /etc/powersaved/sleep and add a number of USB modules to UNLOAD modules list, may need some tries to get them all
