blkid didn’t show linux swap partition UUID

For some strange reason after I clone my Ubuntu 9.10 linux partition, my swap partition didn’t have UUID anymore and I can not view it via “blkid” and have to mount it to the device path (/dev/sda2) in /etc/fstab
After some googling I found the workaround :

1. View the UUID

cat /etc/initramfs-tools/conf.d/resume

2. Set off swap partition and apply the UUID found at no. 1

sudo su

swapoff -a
mkswap -U $(awk -F”=” ‘{print $3}’ /etc/initramfs-tools/conf.d/resume) /dev/sda2

3. Modify my /etc/fstab so the swap partition part contain the UUID

UUID=7b27ee38-6510-4cfa-9e8e-bc77a5e8ce4e none swap sw 0 0

Compiling Axioo Pico DJV 712 WiFi driver on Ubuntu

Just bought a netbook – Axioo Pico DJV 712 – and installed Ubuntu 9.10 Karmic Koala on it. Everything went fine until I tried to connect it to my wireless hotspot – no wireless connection! – my Axioo Pico DJV 712 wireless onboard card didn’t even detected by Ubuntu 9.10.

This is what I found later when I run lspci -knn

Axioo Pico DJV 712 use Realtek 8172 wireless card and ubuntu 9.10 didn’t load a driver for it, google found this for me rtl8172 wireless driver.

This is how I made those driver worked on my Ubuntu 9.10

1. Updated my Ubuntu 9.10 so I can compile the rtl8172 driver

sudo apt-get install build-essential

2. Downloaded the rtl8172 wireless driver

3. Extract it :

tar zxvf rtl8192se_linux_2.6.0010.1012.2009.tar.gz

4. Change directory : 

cd rtl8192se_linux_2.6.0010.1012.2009

5. Compile and Install

make

sudo make install

6. Reboot

Now I have an Axioo Pico DJV 712 with a working wireless onboard card.

Note : for those who need the 64 bit driver here’s the link : rtl8172 64bit driver
