Remastersys: the easy tool to backup your PC or to create a personalized Linux (Debian – Ubuntu) distribution

Everyday we improve the OS we usually use adapting it to our specific needs. Consequently, we are worried about major OS upgrades between one version to another because we know that bugs could affect our installation and indirectly corrupt our saved data. Usually backup software are the right solution for data but, if something goes wrong, we have to reinstall all our OS and reconfigure it. Better, we have to spend many hours to download and configure all the single software we had installed into our original OS.

This is always but annoying and time-wasting. To avoid this specific problem we can decide to install Remastersys on our Linux distribution and use it regularly. Remastersys is very simple to install. For example, if you use Ubuntu, you have just to download its pgp key and save it into the Home folder then you can go to Synaptic Package Manager –> Other Software –> Add and enter the apt line specific for your Ubuntu version:

deb http://www.remastersys.com/ubuntu precise main

or

deb http://www.remastersys.com/ubuntu quantal main

if you use quantal.

On Synaptic Package Manger go to Edit and click on Reload Package Information then look for remastersys. Now you have Remastersys launcher under System –> Administration.

Remastersys has a very intuitive menu and you will be able to powerfully use it after just few tests. Please, remember to set-up Remastersys using its Customize –> Configure menu and you avoid any beginner mistake. If your iso will be bigger than 4GB, and you want to save it in to a FAT disk, you have to back-up documents, pictures, videos, etc.. separately because FAT formatted disks don’t allow files bigger than 4GB.

Important, if you are creating a ISO to distribute it to friends, don’t forget to not include personal folders, documents or your sensible data. Enjoy it and, if you want to share with us your personal Debian – Ubuntu distribution, add the specific download link into a comment to this post!  AddThis

Repair GRUB on IBM Thinkpad – The best Linux solution

When you decide to add another OS to the usual OS on your PC you can potentially damage your grub package. The Grub (GNU GRand Unified Bootloader) is the “soul” of you hardware, the program which allows your PC to find the OS during the boot-up.

Today we will not discuss about the old and new malware that are able to influence the GRUB but we will focus our attention on how repairing your computer when you see grub rescue> on your black screen…

The first solution you can find on internet is a detailed command solution but it was unfortunately usefulness in my case because my PC was not able to correctly accept the insmod command. Consequently I decided to use a portable rescue CD-USB to fix the matter.

Normally, if you use an Ubuntu derived OS, you can use Boot-Repair and it will semi-automatically fix your Grub problem in just few minutes. In any case, it is moderately easy but you have to be 100% sure about what HD partition you want to repair. As usual, this wasn’t my case. I had to find something more generic -in term of serviced OS- but effective.

At the end I bumped into the Boot Repair Disk. I had just to burn the free iso on a RW DVD and I could start to test it on my “out of service” laptop. The Boot Repair live CD is a wonderful tool! As soon as you boot up the live CD, Boot Repair guides you to the best possible solution. You have just to follow the suggestion on the screen and, in few minutes, the Boot Repair Disk is able to fix the Grub and to perfectly restore your computer.

Easy, Fast, Effective!! AddThis

Solve audio troubleshooting on Ubuntu and start planning to migrate to another Linux OS

It was just a simple system update which dropped off audio on my Ubuntu 12.04. It was really strange to admit that I had experienced a crash (better: an audio crash) on a Linux but the 12.04 Ubuntu actually caused similar problems to a numerous bunch of long-term aficionados around the world.

The real problem with the last Ubuntu versions is that this OS is not supporting properly “old” hardware as it did previously during so many years. Reading some other bug reports on the web I discovered that these audio troubleshooting crashes happen principally to “old” IBM ThinkPad and Dell. I hope Ubuntu developers will consider to solve immediately these kind of issues or many users certainly migrate to other Linux version.

In any case the best and complete guide to solve audio troubleshooting has been developed by Ubuntu itself. The guide is very detailed but, if you want to definitively solve this bug, you have to spend more or less 40 (forty…. sic!) minutes and follow all the 17 (seventeen… sic!) steps.

In my case the audio was back after the first step and I decided not to follow the other instructions but the audio troubleshooting comes back, more or less, every two months. Just to you if you want to spend 40 minutes only one time or a couple of minutes every two/three months.

When I consider all the problems I had with Ubuntu on “old” hardware starting from the 12.04 version, my advice is to start thinking about a migration to another Linux OS. I am testing some Ubuntu alternatives and in the next weeks I will post something about the tests I’m doing on old laptops. Stay connected!   AddThis

Setting up File Sharing Between Windows, Linux, and Macs with Samba! by NixiePixel

Samba: share Linux Folders with your windows machines by technoblogical

Another way to share files between Ubuntu and Windows

This tutorial will show you another way to share and to access the network share folders between Windows and Ubuntu machines. When file sharing is enabled, both systems can access files and folders on any of the PCs. Users with accounts on Ubuntu systems will also be able to access the content directly from your home.

1. To begin, you will need to log on to your Windows operating system. Click ‘Start’ -> search for ‘Network and Sharing Center’ and click on it.

2. Access the ‘Change advanced settings sharing. ” option.

3. Enable file sharing and backup as well.

4. At this point, you need to switch your operating system to Ubuntu. Once you log in, click on ‘Ubuntu menu -> System Tools ”

5. Then select ‘Ubuntu Software Center. ”

6. Find and install ‘Samba‘. This software is required for a better compatibility between the two operating systems.

7. After Samba is installed, you should go to ‘System → Administration –> Samba’.

8. Then click ‘Preferences -> Server Settings’.

9. Write the name of the workgroup you set for your Windows PC(s). If you do not know the exact name because you did not set it, the default name for Windows Workgroups is set to ‘WORKGROUP‘ (capitalizing is not required, however, since Windows is generally not case-sensitive). AddThis

Fix .ICEauthority problem at Linux boot up

After upgrading my Ubuntu 10.04 LTS I had an error window at every boot up session. The message advised me about:

Could not update ICEauthority file /home/username/.ICEauthority

ICEauthority is the Inter-Client Exchange (ICE) Protocol that allows  authentication, negotiation, setting up and taking down connections between programs. In few words, if two programs have the same cookies, they will talk and exchange data through ICEauthority.

To fix this matter open the Terminal and type:

ls -al

Then you find a line similar to this:

-rw——-  1 root        root           35226 2011-10-06 00:24 .ICEauthority

This means that your profile (username on a Linux OS) is not allowed to manage ICEauthority and you have to gain full permission to solve the boot up problem:

sudo chown username:username ~/.ICEauthority

Where username is your user profile on Linux.

Then type:

sudo chmod u+rw ~/.ICEauthority

To check if you succeeded, type again:

ls -al

and this time you will find a line like this:

-rw——-  1 username username    35226 2011-10-06 00:24 .ICEauthority
