Simple, fast and without losing any data on my PC!
sudo apt-get install xubuntu-desktop

Ubuntu Lucid 10.04 – insane cpu usage in Flash Player
Some friends told me that in many Laptop with Intel 82845G/GL video chipset and Ubuntu 10.04 Lucid there are a lots of problems in Flash Player.
In many case, often when you use Youtube video, the CPU usage raise up to 100% and the Xorg crash totally. You must restart Ubuntu to have a normal usable system.
I tried to help a friend a few days ago and the only good solution was to update the Linux Kernel at the 2.6.34 version.
The problem is not ‘completely solved but appears less frequently.
You can try to take the new kernel deb files using this official Ubuntu repository and update your standard 2.6.32-22.
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-lucid/
There are also a 2.6.35 Kernel but I have not tried yet.
http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.35-rc1-lucid/

How to force the execution of a program in a specific core
In some case I need to force the execution of a software in a specific core.
To do this I use a Linux program named “taskset”
It’s really simple to use and really useful.
taskset -c 0 program_name
-c 0 it means to execute the program to the first core, -c 1 it’s the second core.. and so on
For example to force execution of VLC to che second core I can use this command
taskset -c 1 vlc
Linux SSH Tunnel – HowTo
This is a simple howto use a SSH Tunnel under Linux
This an example of the correct syntax
ssh -l username_ssh ip_firewall -L local_port:remote_pc:remote_port
For example: if you want to connect from your linux client to a remote pc via VNC through a linux firewall
you can use this command
firewall ip is: 72.35.34.2
firewall username is : vncext
remote pc ip is: 192.168.0.23
vnc port is: 5900
local port is: 5900
ssh -l vncext 72.35.34.2 -L 5900:192.168.0.23:5900
after this command you must insert the vncext password for 72.35.34.2
and now you can connect to remote vnc simply use this command
xvnc4viewer 127.0.0.1

Recovering Ubuntu After Installing Windows
For recovering Ubuntu (or Debian) after installing Windows there are many way.
For me the simple way it’s:
1 – boot from Ubuntu Live CD (if possible the same version as your installed version on the PC)
2 – open terminal
3 – execute this command
sudo grub-install --root-directory=/dev/sdaX /dev/sda
this command reinstall the grub loader for the /dev/sdaX root partition (X is for 1 / 2 / 3 etc. you must change this value in according of your partition table, may be different for a custom installation);
also sda may be sdb or sdc etc. you must check you /etc/fstab or execute mount to see what is your root file system
