Ubuntu 9.10 Desktop Edition na Tablet PC-u

Prije nekoliko mjeseci stigao mi je na kucnu adresu primjerak novog Ubuntu OS-a, verzije 9.10.

Nabavit ga mozete kod nas ili naruciti direktno od Ubuntu-a.
http://www.ubuntu.com/getubuntu/download

Tako sam odlucio vidjeti sto to novo nudi Ubuntu, te ga isprobati na Tablet PC-u.
Radi se o starom tc1100 modelu, 1.5 GB RAM-a, 40GB hard diska i 1Ghz Centrino procesor.

Live CD je radio izvrsno pa sam odlucio ga instalirati sa jednim jedinim ciljem, vidjeti kako se Ubuntu nosi sa Tablet PC-om.
Prijasnja verzija je dobro radila:

Ono sto je problem kod Tablet PC-a je prepoznavanje olovke i njezinih mogucnosti. To sam sve rijesio sa:
First things first

Apply all updates through the update manager

Open System > Administration > Update Manager.
Click install updates
Ubuntu 9.10 now makes it easy to login without the keyboard attached because the on-screen keyboard is now integrated into the login menu. Just activate it from the login screen by opening the preferences menu from the icon at the bottom.

Installing NVIDIA graphics driver

The proprietary NVIDIA driver is required for screen rotation, special effects, etc.
Open System > Administration > Hardware Drivers.
Click activate.
It will download and install the driver; be patient.
Reboot.
Fixing the stylus and graphics

The following xorg.conf will allow for screen rotation.
sudo gedit /etc/X11/xorg.conf

Replace everything in the file with the following text:
Section "Monitor"
Identifier "Configured Monitor"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
Option "AddARGBGLXVisuals" "True"
EndSection

Section "Module"
Load "glx"
EndSection

Section "Device"
Identifier "Configured Video Device"
Driver "nvidia"
Option "NoLogo" "True"
Option "RandRRotation" "True"
Option "NvAGP" "1"
Option "RenderAccel" "False"
EndSection

Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
EndSection
Save and close.
This will fix the stylus right-click and rotation.
gedit /usr/share/hal/fdi/policy/20thirdparty/10-linuxwacom.fdi

Replace everything in the file with the following text:

Save and close.
You must reboot for changes to take effect.
Installing useful applications

Cellwriter is a handwriting application used for entering text using the stylus.
Xournal is a note-taking application.
Xbindkeys is used for making the stylus buttons work.
Install them with this command:
sudo aptitude install cellwriter xournal xbindkeys wacomcpl

Make xbindkeys start up automatically.
Open system > Preferences > Startup Applications.
Click add.
Enter xbindkeys in each box.
Click add.
Repeat for cellwriter if you want it to start automatically.
Configure xbindkeys for custom key mapping
gedit .xbindkeysrc

Enter the following text into the file:
"rotate"
b:30
"xournal"
b:31
"cellwriter"
b:32
#"customcommand1"
#c:159
#"customcommand2"
#c:151
c:159 and c:151 are the Q and screen-switching buttons respectively. If you want to map them to a command, just remove the #s and enter your command in the appropriate spot.

Save and close.
Other tweaks and fixes

**IMPORTANT** Switch to root so we can enter the following commands without worrying about "sudo" on each one.
sudo su

Load the tc1100 module needed for controlling the jogdial and wireless card status.
modprobe tc1100-wmi
echo "tc1100-wmi" >> /etc/modules

Allow the jogdial to control screen brightness.
This is the only way you can control screen brightness, so this is how I prefer to use the jogdial. If you don't do this step you can keep using it as page up and page down.

gedit /etc/rc.local

Add this before exit 0:
echo 0 > /sys/devices/platform/tc1100-wmi/jogdial
Save and close.
Fix stylus calibration after resuming from suspend.
gedit 10_calibrate.sh

Enter the following text into the file:
#!/usr/bin/env bash

FILE=/tmp/calibration
XSETWACOM=/usr/bin/xsetwacom

function store_value()
{
value=`$XSETWACOM --display :0.0 get $1 $2`
echo "$XSETWACOM --display :0.0 set $1 $2 $value" >> $FILE
}

# Store calibration of all devices
function store_devices_calibration()
{
>$FILE
store_value "stylus" "TopX"
store_value "stylus" "TopY"
store_value "stylus" "BottomX"
store_value "stylus" "BottomY"
chmod +x $FILE
}

# Store calibration of all devices
function restore_devices_calibration()
{
if [[ -e $FILE ]]
then
( sleep 2; $FILE )&
fi
}

MODE=$1

case "$MODE" in
hibernate|suspend)
store_devices_calibration
;;
thaw|resume)
restore_devices_calibration
;;
*) exit $NA
;;
esac
Save and close.
chmod +x 10_calibrate.sh
mv 10_calibrate.sh /etc/pm/sleep.d/

Make a screen rotation script.
gedit rotate

Enter the following text into the file:
#!/bin/sh
if [ -n "$(xrandr | grep 768x1024)" ]; then
xrandr -o normal
xsetwacom set "stylus" Rotate NONE
else
xrandr -o left
xsetwacom set "stylus" Rotate CCW
fi
Save and close.
chmod +x rotate
mv rotate /usr/bin/rotate

This will be used later on after we patch the drivers for the stylus buttons. You must have applied the above xorg.conf and installed the nvidia driver for it to work properly.
Prevent the screen from locking.
It sucks when the screen becomes locked, you don't have a keyboard attached, and you can't access cellwriter.

**NOTE: These commands must be run as your normal login user, not as root/sudo. So if you are in the terminal as root, just type "exit" or open a new terminal to run these.

gconftool -s /apps/gksu/disable-grab -t bool true
gconftool -s /apps/gnome-power-manager/lock/suspend -t bool false
gconftool -s /apps/gnome-power-manager/lock/hibernate -t bool false
Fix the headphone jack.
In the Sound preferences, make sure "jack sense" is enabled. Otherwise sound will still play from the speakers if you have headphones plugged in.

Bottom up, olovka radi, on screen keyboard radi.

U usporedbi sa XP-om Tablet PC edition, Ubuntu nazalost ne iskoristava ni 5% potencijala ovakvog racunala, i nazalost to ce jos dugo tako ostati. Dok god se netko od proizvodjaca ne zainati i napravi custom verziju Linuxa za svoj hardware.

Ubuntu 9.10 je lijep i moze se sa efektima usporediti sa Windows 7 (popularni cube itd..) Programa ima vise nego sto je ikome potrebno, no business iskoristivost je slabija.
