I assume that you have a separate home partition. We are not using any software other than tar to completely backup and restore a Ubuntu Linux box. We are backing it up on external drive mounted at /media/storage Backup Open a terminal. cd /media/storage (or any other place that you want the backup to be made) sudo tar cvpzf backup.tgz --exclude=/proc --exclude=/lost+found --exclude=/backup.tgz --exclude=/mnt --exclude=/sys --exclude=/media / This will take some time and create a file called backup.tgz. This is your whole system backup excluding your home partition as it is safe in a different place. Restore Open a terminal on the system you want to restore the backup. cd /media/storage (After you have plugged in the external drive having the backup file you just made.) sudo tar xvpfj backup.tar.bz2 -C / Make the directory you excluded in the backup command. This concludes a successful restore of your system.

One of the problem I faced after Karmic Koala was Xchat won't minimize to tray i.e the system tray icon wouldn't show, instead Xchat would close. The problem is same on Lucid Beta as well. I had post one solution minimize-xchat-to-tray-in-karmic . But this doesn't work if you have set Xchat on your startup list. Xchat sometimes minimizes to tray and some times not when it is set on startup program list. So I have come up with a solution as below. In you home directory make a file .xchat_start with following content #!/bin/bash sleep 30; xchat Set execute permission on this file by typing chmod +x .xchat_start in terminal Now go To Menu->Prererences->Startup Applications Click Add Add name Xchat and command /home/u ser_name /.xhcat there

Many laptop put their webcam upside down resulting in flipped images in Ubuntu. There were fixes for some but for some you had to physically remount the camera. The webcam that comes with Lenovo Ideapad Y510 is also mounted upside down. Unluckily there wasn't any simple fix for this. (some people rotated the camera physically). Fortunately Hans de Goede  came with a beautiful solution . Open Terminal and add libv4l ppa sudo add-apt-repository ppa:libv4l/ppa Update your software list sudo aptitude update Install libv4l sudo aptitude install libv4l-0 You have to use the following command to open any application that uses webcam LD_PRELOAD=/usr/lib/libv4l/v4l1compat.so application_name If you use 64 bit system, use the following command LD_PRELOAD=/usr/lib32/libv4l/v4l1compat.so application_name
