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
That’s all!
The following system recovery tools will be useful to you if you are facing problem of data loss or if your system is simply crashing. It is advisable to burn copies of these tools much before any disaster strikes.
Open Source and Free approach:
G4L aka Ghost for Linux is one of the system recovery tools that is mainly a cloning and hard disk and partition imaging tool. This tool is similar to “Norton Ghost”. The images created are compressed optionally and transferred to a FTP server instead of opting for cloning locally. Ideally, of the several tools described above it is advisable to use the most suitable tool for your needs. The tool that will be most useful during a crisis like a crash or server failure will be a better tool.
The Ultimate Boot CD is one of the system recovery tools which will be very helpful when you want to run CDRom-based diagnostic tools thereby consolidating as many diagnostic tools into one bootable CD as possible. Since you can now boot from USB memory devices a script you can run “Ultimate Boot CD” from USB memory stick and a script on the script on the CD will enable you to boot newer systems from your USB sticks. This is many steps ahead than many of the other recovery tools. Moreover it gives you the flexibility of booting your system with a USB memory stick.
Knoppix is one of the system recovery tools which is essentially a bootable CD with GNU/Linux software. It ensures automatic detection of hardware and supports a wide range of devices like sound cards, most of the graphic cards, USB and SCSI devices and other peripherals. It can be used as an educational CD, a Linux demo or for system recovery purposes. Alternatively it can be used as a commercial platform for software demos. There is no need to install anything on the hard-disk as the CD is capable of storing 2GB of software installed in it. Thus this tool is a truly multi-purpose recovery tool.
Proprietary solutions:
O&O Disk recovery: This software tool scans every portion of your hard-disk, digital camera or memory card for lost files. It is so effective and reliable that it is possible to reconstruct data even when files systems have been destroyed or formatted. More than 350 types of files like music formats, word documents, movie, graphics, Excel workbooks, photo and access databases can be recognized, reconstructed and restored.
SuperDuper is one of the system recovery tools makes recovery effortless as it creates a completely bootable backup effortlessly. The strengths of this software are that it is user-friendly, easy to use with a built-in scheduler that it makes backup automatically. Moreover it performs well independent of the processor that is both on Power PC Macs as well as Intel PCs. It is particularly useful when your software application with the latest update is not working or when your hard drive begins to make noise. It is also very handy when you want to restore a stable copy of your system though you do not want t lose your existing system files or cases like this. 
Lubi is a useful tool for all people who like to experiment different Linux OS on their PCs. In particular Lubi has been thought to let you install Ubuntu in just few clicks and without risking annoying “secondary effects” on your computer. In our Linux Page (in Spanish) we have posted a small but effective review with all the necessary links to the Lubi project and we have also listed all the Linux OS (PCLinuxOS 2007 32-bit, openSUSE 10.2 32-bit, Gentoo 2007.0 32-bit, etc..) already tested for a safe -Lubi- use. We strongly recommend Lubi for all users who want to deeply test Ubuntu (and its features) without starting from the Live CD.
Today, in our Linux page we have posted a brief review about Wubi: a simple and effective Ubuntu installer for Windows users. With just few clicks you can easily install Ubuntu without modifying the partitions on your pc (for this reason there are no -or very low- risks of “fatal errors” for your computer). All the Ubuntu files are stored in just a single folder so it is very simple to uninstall Ubuntu if you decide not to use it anymore. In few words, Wubi allows Linux beginners to try all the positive features of Ubuntu without risking undesirable secondary effects. Recommended!
Today, in our Linux page we post a review about BUM a powerful, graphic Boot-up Manager for Ubuntu. Using this light software you can modify and decide what programs run at startup. BUM is a very useful tool, precious especially when you notice that your Ubuntu boot is becoming slower than in the past. Initializing the Boot-up Manager is very simple and fast: recommended for the Linux beginners (like us)!
Yesterday a new version of Ubuntu (Feisty Fawn 7.04) has been released. This new version seems to be more powerful and enjoyable than the 6.10 and we hope it will actively contribute to spread the use of Linux. For people using Ubuntu 6.10, Ubuntu released simple and brief instructions to upgrade fast the OS.
In our Linux Page, we posted a brief tutorial about solving problems generated by an Ubuntu upgrade (this kind of problems is not common but unfortunately sometimes it happens..). The post, inspired some Italian blogs we found on the web, is very simple and effective and we hope it could be useful… in case of emergency. See you soon!
Super Grub is a very practical and useful free bootable cd which can be very useful when you need to solve boot problems in Linux, Windows and other OS Independent. In our Linux page, Frank wrote a descriptive post about the many features you can find (and effectively use) in this terrific bootable cd. Super Grub is very light (just 1.45 MB of cdrom .iso), supports seven different languages and can be downloaded also in its floppy disk version.
