New_icons_17 Pulire e ottimizzare Ubuntu 13.04 Raring Ringatail – con applicazioni GUI

I installed ubuntu 13.04   raring ringtail two week beforet it was officially released. I installaed Lubuntu 13.04. However, I often use as a desktop environment the awesome window manager.  I  appreciate  the advantage of kernel 3.8.xx that leads to an improvement in the recognition of hardware devices. In Lubuntu strangely I’m currently experiencing some annoying logout. Now is the time to do the cleaning. In this post thas use as template previous Clean up and optimize Ubuntu 12.10 Quantal Quetzali I have added output of commands.

For cleaning up Ubuntu 13.04 , you can use GUI applications like synaptic ,bleachbit with baobab to check disk space and or  ubuntu tweak  but I prefer to use the terminal.

Here are the commands That I use to save space and clean up all Ubuntu versions ( Ubuntu, Lubuntu, Xubuntu … )

Cleaning up Ubuntu using the terminal

Let’s start by checking the occupation of disk space you can use the command

df -a
maurizio@lub12-10-i2c:~$ df -a
Filesystem     1K-blocks      Used Available Use% Mounted on
/dev/sda3       20027728  11473844   7529864  61% /
/dev/sda13      98645612  71807680  21820332  77% /media/Backup

then check the size of the main folders

sudo du -sxm  /[^p]* | sort -nr   | head -n 15
maurizio@rarl1304:~$ sudo du -sxm  /[^p]* | sort -nr   | head -n 15
6202	/home
3483	/usr
916	/var
398	/lib
68	/root
55	/boot
17	/etc
10	/sbin
10	/bin
4	/lib32

Remove unnecessary libraries and packages:

To delete all package dependencies removed

sudo apt-get autoremove

delete the files (.deb) of the packages that are no longer installed in the system;

sudo apt-get autoclean

The following command is really interesting, because it allows the removal even of the configuration files. This can be useful when you want to reinstall applications from scratch.

sudo apt-get purge

clean  is much more radical than autoclean. It removes any files .deb  from the apt cache, including those relating to the packages currently installed. This command allow a good a good recovery of disk space counterpart is that if you reinstall a package it have to be downloaded.

sudo apt-get clean

##r remove from the cache (/ var / cache / apt) any package, except for the lock files

I usually tie together the commands with:

sudo apt-get autoremove && sudo apt-get autoclean && sudo apt-get purge && sudo apt-get clean

In my case the directory /var is not particularly large and the recovery of space is small. But it is also possible to recover more than 1 GB of disk space

Now, check and resolve any errors or broken dependencies with:
sudo apt-get check ; sudo apt-get -f install
maurizio@rarl1304:~$ sudo apt-get check ; sudo apt-get -f install

OK. There were no problems. Better that way.

Remove orphaned libraries
sudo apt-get install deborphan
sudo apt-get remove --purge `deborphan`; sudo apt-get autoremove
sudo deborphan | xargs sudo apt-get -y remove --purge and

Everything ok

0 upgraded, 0 newly installed, 0 to remove 
To search and cleaning unused configurations

To search folders and unused configurations files we can use :

dpkg -l | egrep "^rc" | cut -d ' ' -f3
maurizio@rarl1304:~$ dpkg -l | egrep "^rc" | cut -d ' ' -f3

To cleaning a configuration we can use

sudo dpkg --purge jackd2

or to cleaning all unused configurations files we can use :

sudo dpkg --purge `dpkg -l | egrep "^rc" | cut -d ' ' -f3`

Remove Old Kernel

Each version of the kernel can occupy up to 150 MB. If you have downloaded the headers you get 250MB of space. Therefore becomes crucial periodically remove some of the older kernels.

Check the current kernel t

uname -r
maurizio@rarl1304:~$ uname -r

View the installed kernels

dpkg --list | grep linux-image

maurizio@rarl1304:~$ dpkg --list | grep linux-image 
ii  linux-image-3.8.0-19-generic          3.8.0-19.30                         amd64        Linux kernel image for version 3.8.0 on 64 bit x86 SMP
ii  linux-image-3.8.0-21-generic          3.8.0-21.32                         amd64        Linux kernel image for version 3.8.0 on 64 bit x86 SMP
ii  linux-image-extra-3.8.0-19-generic    3.8.0-19.30                         amd64        Linux kernel image for version 3.8.0 on 64 bit x86 SMP
ii  linux-image-extra-3.8.0-21-generic    3.8.0-21.32                         amd64        Linux kernel image for version 3.8.0 on 64 bit x86 SMP
ii  linux-image-generic                                  amd64        Generic Linux kernel image

Lists the headers installed

ls /usr/src | grep 'linux-headers'
maurizio@rarl1304:~$ ls /usr/src | grep 'linux-headers'

First remove the headers
using somethings like this

sudo apt-get purge linux-headers-3.8.0-19
maurizio@rarl1304:~$ ls /usr/src | grep 'linux-headers' 
maurizio@rarl1304:~$ sudo apt-get purge linux-headers-3.8.0-19
Reading package lists... Done
Building dependency tree       
Reading state information... Done
The following packages will be REMOVED:
  linux-headers-3.8.0-19* linux-headers-3.8.0-19-generic*
0 upgraded, 0 newly installed, 2 to remove and 3 not upgraded.
After this operation, 72,1 MB disk space will be freed.
Do you want to continue [Y/n]? 
(Reading database ... 192109 files and directories currently installed.)
Removing linux-headers-3.8.0-19-generic ...
Removing linux-headers-3.8.0-19 ...

then remove any specific kernel that is no longer needed

sudo apt-get purge linux-image-3.8.0-19-generic

Remove unnecessary location data packets

To remove packages and languages ​​that do not involve using the program localepurge.

sudo apt-get install localepurge

In the window that appears after installation, select the languages ​​you wish to protect.
Here you can select the languages ​​that interest us.
for example we can check:


 sudo localepurge

to reconfigure localepurge type

sudo dpkg-reconfigure localepurge

To save space: remove o shrink files

home directory

Home directory is a bit large so we can check
the subfolders size using the commands
cd /home/

du -sm * .[^.]* | sort -nr   | head -n 15
maurizio@rarl1304:~$ sudo du -sm * .[^.]* | sort -nr | head -n 15
3438	GrandOrgueCache
1159	.cache
709	Music
392	Fin
119	.config
62	.opera
61	.local
47	Videos

Files to check periodically to save space:


One of the files that can grow up to tens of GB and that may need to check is the file:

This file can be erased from time to time.

or to reduce it and keep last 200 lines of messages

    cd ~
    tail  -n 200 .xsession-errors  > xsession-errors
    mv  xsession-errors .xsession-errors

A home directory that you can grow a lot is the directory /cache.
There there are the browsers cache so to clean up it I prefer to use browser commands.

The directory /home/my-home/tmp should be checked and emptied every so often.

directory  /var

at the root level, from time to time, check the   /var directory :

to display the size of the /var

sudo du -sxm /var/* | sort -nr | head -n 15

Alert. You should only delete files. Absolutely not delete the folders that contain them.

Large size file

May be useful to check if exist large size files everyware e for any users.
The command for 750MB size files may be like:

sudo find / -size +750M -exec ls -lhG {} \; | more


When you start ubuntu like any S.O. are activated services that are not always necessary with the inevitable resource consumption. To check the services that are not strictly necessary on a terminal you can use sysv-rc-conf.

to install

  sudo apt-get install sysv-rc-conf

to start

  sudo sysv-rc-conf

Check or uncheck the options to set the start whether or not a service in a given runlevel (Less services are running more resources are available).

Free up RAM

We can try to maximize ram  in ubuntu 13.04 with

sudo -s   
Write the data in the buffer memory to disk.
Let's free some memory cache inactive
echo 3 > /proc/sys/vm/drop_caches

Optimize Ubuntu

Manage archives

Install applications to manage archives of files compressed.
If one needs to use the various formats of compressed files evaluate the installation of the following packages.

sudo apt-get install unace unrar zip unzip p7zip-full \
    p7zip-rar sharutils rar uudeview mpack lha arj cabextract file-roller
