Configuring Soundgraph FingerVU 706 on Ubuntu 10.04

This is the first post on my blog. As the title suggests, this blogs describes how to configure Soundgraph USB Monitor FingerVU 706 to work as an extended monitor on Ubuntu 10.04 (32 bit). ( Presently the monitor works only as a display and I have not been able to configure the remote control or touch screen input)

Due to paucity of time and most importantly patience, the guide is written in 'Cut the crap out' style.

Before one proceeds ahead it is important that your system is updated and has latest updates installed.

 sudo aptitude update

sudo aptitude upgrade

Once you have achieved this, it is time to get new kernel updates



cd ~/Desktop

mkdir new_kernel

cd new_kernel



wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/linux-headers-2.6.34-020634_2.6.34-020634_all.deb

dpkg -i linux-headers-2.6.34-020634_2.6.34-020634_all.deb



wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/linux-headers-2.6.34-020634-generic_2.6.34-020634_i386.deb

dpkg -i linux-headers-2.6.34-020634-generic_2.6.34-020634_i386.deb



wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/linux-image-2.6.34-020634-generic_2.6.34-020634_i386.deb

dpkg -i linux-image-2.6.34-020634-generic_2.6.34-020634_i386.deb

In next step we shall install dependencies and compile latest package from the git core

sudo apt-get -y install libusb-dev xorg-dev xserver-xorg-video-displaylink git-core

cd ~/Desktop

mkdir libdlo

cd libdlo

wget http://people.freedesktop.org/~berniet/libdlo-0.1.2.tar.gz

tar -xzpf libdlo-0.1.2.tar.gz

cd libdlo-0.1.2

./configure

sudo make install

Now is time to edit /etc/gdm/Init/Default file. Insert following lines of code in the file where the gdmwhich() function ends



XRANDR=`gdmwhich xrandr`

if [ "x$XRANDR" != "x" ] ; then

$XRANDR -o 0

fi

Now comes the most tricky and important step of rewriting your /etc/X11/xorg.conf file.
Most importantly backup your existing xorg.conf file so that you can recover from a crash



sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig

Once this is achieved, I suggest that you replace contents from /etc/X11/xorg.conf file with this



Section "ServerLayout"                                 

Identifier "touchscreen"

Screen  0  "DisplayLinkScreen" 0 0

EndSection     



Section "Files"

ModulePath  "/usr/local/lib/xorg/modules"

EndSection



Section "Device"                                                  

Identifier  "DisplayLinkDevice"

Driver      "displaylink"                

Option      "fbdev" "/dev/fb0

EndSection



Section "Monitor"                                                 

Identifier  "DisplayLinkMonitor"  

EndSection                                                           

Section "Screen"                                                  

Identifier  "DisplayLinkScreen"               

Device      "DisplayLinkDevice"    

Monitor     "DisplayLinkMonitor"    

SubSection "Display"                          

Depth       16                       

Modes       "800x480"

EndSubSection                                     

EndSection

Connect your monitor and reboot your PC. You should be able to see the GDM greeter on your usb display. If you have reached till here, you are doing fine. In case gdm crashes, it is most probably due to two reasons firstly junk characters pasted or wrong frame-buffer device path.
Presently /dev/fb0 works for me. If you suspect this change this to /dev/fb1. You can find the framebuffer devices installed by simply doing ls /dev/fb*.

Assuming that you are on track till here. Drop to another virtual console. We shall revert back to our original file which we have backed up and backup the existing configuration



cd /etc/X11/

sudo mv xorg.conf xorg.conf.fingervu706

sudo cp xorg.conf.orig xorg.conf

sudo service gdm stop

sudo service gdm start

Now you shall have a black screen on your USB monitor and gnome desktop on VGA/DVI display
Following steps need a bit of trial and error and understanding of xorg.conf file directives. I am posting contents of three files.
My original xorg.conf.orig file
FingerVU config file xorg.conf.fingervu706
and lastly and most importantly, my working merged xorg.conf file merging directives from both the files above

xorg.conf.orig

Illustrated Guide to Syncing Blackberry on Ubuntu Karmic

The reason why i decided to write this post was the lack of a complete and comprehensive guide on achieving syncing of Blackberry on Ubuntu.

This article is not intended for Uber geeks but instead for dummies like me. I have tried to make the article as illustrative and self explanatory as possible.

Requirements : An internet connected (only for installing required software packages) Linux Box running Ubuntu 9.04 (Karmic Koala) , Blackberry (8400g in my case) and a working data cable. I assume that the user has got atleast some working level knowledge of linux in general and is not bamboozled by terms like Synaptic, Evolution, Terminal, sudo et al

Step 1: Installing necessary Packages.

Use Synaptic and install following software packages.

multisync0.90 , barrybackup-gui, barry-util,libbarry0,opensync-plugin-barry,opensync-plugin-evolution,multisync-tools

Alternatively you can install them from command line

sudo aptitude install multisync0.90 barrybackup-gui barry-util libbarry0 opensync-plugin-barry opensync-plugin-evolution multisync-tools

Step 2: Connecting Blackberry

Connect blackberry to your computer using the compatible data cable and fire up terminal. We will check whether the computer detects the device or not. Note down the device pin.
sudo btool -l

Step 3: Backing up the Blackberry

Fire up your terminal and execute the barrybackup . Once opened it will prompt you for entering your device name. Enter the device name and Click Ok

Step 4: Configuring Multisync for Syncing Contacts

Open Application->Accessories->Multisync-gui

The initial screen is blank. Click Add to create a new sync group. I have named the group as Blackberry-Contacts. Click Edit to add members to this group. Remember to add Evolution plugin first and then the Barry plugin. Not vice versa. My setup is erroneous

Once you have finished you will have two members on the left hand side pane. evo2-sync and barry sync. Click on evo2-sync member and we shall configure its properties. Select address book of your choice. I have made a blank address book in Evolution and named it as blackberry. Select No Calendar and No To-do as this group will sync only contacts.

Click on barry-sync member and on the right hand side pane you will see a text pane enumerating some setting. Don't worry. just scroll down to the place where it says Device pin and update your device pin there. The default device pin reads 204ad4e8 . Update the pin. There are 2 more digits ahead 1 0 change them and make them 0 and 1. The 1 is enable and 0 is disable. The first 1 is for calendar syncing and the second 1 is for contact syncing. So since we are only going to sync contacts and not calendar we amend the setting to 0 and 1

So the final line reads as thus Device 3009efe3 1 0. Don't worry about the save option the file is saved auto-magically. Close the Window

Now you will see following window. I am repeating again. My setup was erroneous. If you have followed the steps properly you will see the evo2-sync member above the barry-sync. In case you land up in a situation just like me. Just Remove and configure again. Its simple.

Step 5: Syncing Contacts

Click Refresh and you are done. The sync process will start . It takes a couple of minutes

Viola!! Your contacts are synced.

Step 6: Configuring Multisync for Syncing Calendar.

The steps for configuring Multisync-gui are similar to those we took for contacts . Make a new group Blackberry-Contacts. Add evo2-sync member first and barry-sync member next. Click on evo2-sync member and we shall configure its properties. Select Calendar of your choice, select local calendars preferably at first. Select No Address Book and No To-do as this group will sync only calendar.

Click on barry-sync member and on the right hand side pane you will see a text pane enumerating some setting. Don't worry. just scroll down to the place where it says Device pin and update your device pin there. The default device pin reads 204ad4e8 . Update the pin. There are 2 more digits ahead 1 0 change them and make them 1 and 0. The 1 is enable and 0 is disable. The first 1 is for calendar syncing and the second 1 is for contact syncing. So since we are only going to sync calendar and not contacts we amend the setting to 1 and 0. My Setting is wrong
