A standard Ubuntu installation with encrypted hard drive will give you a boot partition and a LVM partition with two logical volumes. If your computer name is “Ubuntu”, the volume group will typically be called Ubuntu, with two volumes: root and swap.

In order to make a logical volume for /home and for /, do the following:

Start by booting onto the alternative version of the Ubuntu cd - the one without LiveCD - and select rescue. The system will automatically find you encrypted and ask for the password. When starting the terminal, you will have to mount a partition - select your boot partition, on my computer /dev/sda1

Make all volume groups active:

sudo lvm vgchange -a y

Run disk check on the volume:

sudo e2fsck -f /dev/mapper/ubuntu-root

Resize the file system to 10G

sudo resize2fs -f /dev/mapper/ubuntu-root 10G

Wait... make some coffee... maybe even bake a cake, there is time enough :)

Resize the volume to 10G

sudo lvreduce -L10G /dev/mapper/ubuntu-root 10G

Important: you have to shrink the file system before the logical volume!

Display how much free space the LVM group has, the first number is free "extents" and the second is in GB, MB etc.

sudo vgdisplay | grep Free

Create the new volume, -l specify the size in extens, -L in GB, MB etc.

sudo lvcreate -l 50 -n home ubuntu

Make the file system

sudo mke2fs -j /dev/ubuntu/home

sudo vol_id /dev/mapper/ubuntu-home | grep ID_FS_UUID=

will give the UUID for the "device", which can be used in /etc/fstab like:

# /dev/mapper/ubuntu-home
UUID=37563b54-50e5-486c-8796-2df55598fb63 /home ext3 relatime 0 2

Of cause you will have to move all data from /home to the new volume, before mounting it at home!

Now put the SIM back in the modem, and connect it to your computer. The below pop up will show up, and you just have to click Config. (If it do not show up, right click on the Network Manager and select Edit Connections.)

Click Next, and select TDC as Service Provider (Fullrate uses TDCs net), click Next again, and give the connection a name and then click Apply.

Now the system should connect you, if you have coverage, and this pop up will appear

Very simple!!! :)

The connection is quite good, and the speed is as promised. Fullrates speedtest at http://speedtest.fullrate.dk/ gives 1.15Mps, while the upload is at 0.25Mps.

The ftp servertest at http://www.fullrate.dk/support/hastighed/ do not work, which might be because the server only allow Fullrate connections, while this is basically a TDC connection.

Downloading a part of an Ubuntu image from HEAnet Ireland gives an average of 115K/s, which is the normal, according to http://www.fullrate.dk/support/hastighed/

Maybe a little to early to say anything works. After 40 minutes the modem lost connection for 5 min, before getting on-line again.

echo "deb http://www.e-oss.net/ubuntu/gutsy/ ./" | sudo tee -a /etc/apt/sources.list
sudo apt-get update
sudo apt-get install pytrainer
sudo apt-get install python-gnome2-extras

To get the Garmin kernel driver working in user space, make an udev rule in /etc/udev/rules.d/51-garmin.rules with this content

SYSFS{idVendor}=="091e", SYSFS{idProduct}=="0003", MODE="666"

Pytrainer is made to use path like /dev/ttyUSBX to connect to the Garmin watch. I believe the right way is to use Garmin usb driver directly, hence usb: in the config. Therefore you have to open /usr/share/pytrainer/plugins/garmin-hr/main.py and change

if not os.path.exists(options.device):

to

if (not os.path.exists(options.device) and not options.device == "usb:"):

In Tools -> GPS Device Plugins -> Garmin* ->Preferences change device to [usb:] and status to [Enable].

Thats it, have fun :)
