It took me some research to get this proved instructions to work for any kind of USB Stick and any Linux/ubuntu distro to boot from.
Any usb-creator GUI did not work (for me) and also caused some bugs…
[Current issue at the releases 15.04 and 15.10] There are problems with the Startup Disk Creator alias usb-creator, if you try to create a 15.04 boot drive from the versions 12.04 LTS and 14.04 LTS of Ubuntu. See this link to the release notes https://wiki.ubuntu.com/UtopicUnicorn/ReleaseNotes#Boot.2C_installation_and_post-install. Unetbootin works from Ubuntu 12.04.5 and 14.04.2 (can make a working USB boot drive for Ubuntu 15.04), but the bug is still there in Startup Disk Creator (tested April 29 2015 (and October 22 for 15.10))

I got a MacBook Air SuperDrive for testing purpose to see if I can write CD-RW on a Laptop with SSD but without CD/DVD drive.
My first thouhgt was nice – it has been recognised by the OS.

Than I wondered why the SuperDrive does not awake when I tried to put in a blank CD-RW…
Is it really true that Apple does nto want us “normal” users to use their Hardware???
My favourite search engine helped me again and many thanks to Christian Moser who solved it for us!
Today I would like to show you my conky system-performance meter. I do use it since the old Ubuntu 13.xx days and I still love it. On top I am very well aware that my conky settings are very basic and show just my needs 😉
How to install conky:
# sudo apt-get install aptitude python-keyring ttf-ubuntu-font-family hddtemp curl lm-sensors conky-all
# apt-get install conky apcupsd audacious xmms2 mpd moc
Customize it to your needs by using the following pages
My conky – config file looks like this:

Till 13.10 Xubuntu uses XScreenSaver as screensaver. In the rare case you installed xfce manually you may want to use
sudo apt-get install xfce4-settings
from the universe package to be able to use the settings manager.
In Xubuntu 14.04 onwards light-locker is default and pre-installed.
Light-locker and xscreensaver – to have both is not a good idea see BUG 1304128.
I personally prefer xscreensaver:
# apt-get remove light-locker
# apt-get install xscreensaver xfishtank xdaliclock
Which looks like this …
After upgrading to Xubuntu 15.10 (I should write a section for this experience as well) I got aware of all my old sessions I stored to play around with different auto-start configs.
First question in mind was “Where are those sessions stored?”, second was “How to modify them or remove the ones I don’t need/like anymore?”.
Well, first I remembered about
$HOME/.cache/sessions directory – and viola – here they are listed in some cryptic file names…
Anyhow – sorting the output with
# ls -ltr you get very easy a clear picture what you should look into more deeper.
is the look and feel of my directory.
Either you delete all the files including the thumbs directory or you look inside the -file and delete the lines below
[Session: Default|Whateveryournamewas] for each individual session.
The idea behind this post was born during Christmas prepare 2015. We wanted to print a photo on the back side of a calendar for 2016 and laminate it.
All we needed was the photo in a specific size on paper. Nothing easier than this, my first thought.
LOL, Yes … how to get the photo from my wife’s windows pc to my Xubuntu and size it with gimp.
here is my work list:
* enable samba share
* secured with user & passwd
* only useable within my private network
* no access from outside
* windows & Linux & mac boxes allowed
Give the default Xubuntu –> Settings –> Share Folders a try…
I got tons of errors during my apt-get update informing me that the repository is currently not available.
Can happen, but after 3 days same message I started to think about to change the repository to a closer / new one.
So I looked around my
/etc/apt/sources.list and searched for a way to modify all old repository entries and replace it with the new one.
sed did the trick for me to be honest
sed -i 's/mirror.skylink-datacenter.de/de.archive.ubuntu.com/g' /etc/apt/sources.list
– and I wonder why I do not use it more oft 😉
As a specialist of “You did forgot to umount your USB Stick” in my virtual machine / local Laptop I always end up with “your USB drive was not unmounted properly”.
Here is what I do to fix the USB Stick:
- # lsusb ## need to check if the USB Stick is recognized
- # df -h ## only one out of many options to check if and where the USB Stick is mounted
- # fsck -Va /dev/
- wait and relax – than DO NOT FORGET TO umount YOUR STICK
Windows is a GUI, UNIX is an operating system!
By operating system, I mean the complete suite of programs, which make the computer work.
It is stable, multi-user & multi-tasking system for servers, desktops and laptops.
UNIX systems also have a graphical user interface (GUI), which provides an easy to use environment.
There are many different flavours and versions of UNIX. They share common similarities.
One of the most popular flavour of UNIX for me is Sun Solaris, followed by Linux and MacOS X.
I was on the way to streamline my desktop and wanted to move some often used helpers to my quick launcher bar.
One of them is my ‘root’-terminal … well, Yes I do want to perform certain actions like fsck and apt-get on cmd-line without ‘sudo’. I know the risk of having a ‘root’-term!
Starting with Alt+F2 and:
gksu 'xterm -e top'
and after the password magically a small xterm with top do pop up.
More for the geeks:
gksu -u root '/usr/bin/xterm -T "root" -bg black -fg green -geometry 140x40'
And now as a launcher in my Quick Launcher bar:
/usr/bin/gksu -u root '/usr/bin/xterm -T "root" -bg black -fg green -geometry 140x40'
tada! it worked …
