How to move pages up and down in tty in Fedora

Yes, people this lady is becoming a tty junkie  photo shiny.gif I prefer it over Konsole and now I am so glad I went through the pain ( photo emo.gif) of learning basics of Vim. There is no need for me to leave tty now, besides from doing obvious Desktop Environment thingies.

If you want to move a page up:

Shift + Page Up

I would like to point out the amount you of pages you can go up is limited  photo piidea.gif In my case I can go up like 8 pages, I’ve heard you can edit this by editing your .bashrc file. When I discover how to do that, I’ll write a how-to  photo nodding.gif

If you want to move a page down:

Shift + Page Down

Let’s say you have moved 5 pages up, but you don’t want to press Shift + Page Down four times to go back to the last page. If you press:

Shift + End

or

Shift + Home

you’ll get back to the last page, from what ever page you currently are.

You could also hit:

Ctrl+l

this clears the screen.

Recommendation: A basic guide to systemd in Fedora.

Well, since the dust of the drama has been settled *coughs Devuan *coughs  photo schater.gif we all know systemd will be the way to go in Linux. Even the OS’s that have been using Upstart will replace Upstart with systemd soon. If you want to get a quick hold of the basics then the Fedora Magazine has great series of articles that will give you a fundamental understanding of systemd.

I have pdf’d the series here (don’t hit the print button blindly, the comments of the articles are also included in the pdf. Yeah I know  photo emo.gif)

1_systemd_initialization
2_systemd_unit_file_basics
3_systemd_converting_sysvinit_scripts
4_systemd_using_the_journal
5_systemd_masking_units
6_systemd_dependencies
7_systemd_template_units

How to return to the Desktop Environment from tty in Fedora

I.had.to.Google.like.MAD  photo piangry.gif to find this solution  photo emo.gif

All you have to do is press:

Ctrl+Alt+F1

You enter tty from the Desktop Envrionment by pressing either Ctrl+Alt+F2 or Ctrl+ Alt +F3 up till Ctrl+Alt+F6 .

If  you want to switch between several tty’s, like  if you are for example in tty3 and want to go to tty2 all you have to do is press Alt+F2 and you are in tty2. Nice huh?

Btw, let’s not use the comment section of this post to debate my Google skills okay  photo talktothehand.gif

Regarding the “Invalid partition table!” error in Fedora on a Dell E5250

invalid_partition_table

If you get this during the boot process of Fedora, you might know that pressing on enter will continue the boot process. If you however don’t want your boot process to stop at the “Invalid partition table!” error, then you should do the following. With the next installation of Fedora, choose “standard partition” in the Anaconda installer (see picture below), the default setting is “lvm” which is the cause of this error.

standard_partition

 Edit: I know on the Dell site, people blame this error on an outdated BIOS. But I still got this error after updating my BIOS.

How to fix Parole’s “Gstreamer backend error” in Fedora 20

I wrote this how to after receiving comments from Rudolf and Pavlo on my earlier how to regarding this issue.

If you get this screen:

updategstreamererror

All you have to do is fire up Terminal and type:

parole --xv false

updategstreamererror2

There might not be much screen activity after you have typed this command, but trust me Parole will work now  photo nodding.gif

When typing the command above,  it is very important that you are NOT logged in as root!!!! If you are, you will get this error message:

updategstreamererror3

If this how to doesn’t work, check this one!

Recommendation: Introduction to Linux (LFS101x)

lfs101x

While I have been quite happy with sites like Coursera, Udacity, Codecademy, edX etc. etc. Sites where you can study Computer Sciences, among st one of the many subjects, online for free. I always wondered why Linux was the great missing factor on all these sites. Well that has changed  photo cheerlie.gif

I am happy to announce that edX will start a free online Linux introductory course  photo worshippy.gif It will start in the 3rd quarter of 2014. You can sign up here.

I would love to hear from people who followed this course  photo thumbsup.gif

How to get Java working in Fedora 20

Suppose you want to play Minecraft, in order to do that you need to have Java installed. You don’t have to worry about versions since Java is backwards compatible, meaning the latest version of Java is capable of running software that was built in an earlier version. In this “how to” we are going to install OpenJDK which is basically a free and open source variant of Java  photo nodding.gif

Fire up Terminal and log in as root:

su

Then type:

yum install -y java-1.7.0-openjdk

java1

Mind you  photo piidea.gif if you need Java to be working in your browser too, you need to install the IcedTea plug in. You install this by typing the following command in Terminal (make sure that your are logged in as root!):

yum install -y icedtea-web

java2

To check if Java installation was succesful, go this site. You will see this screen:

javacheck1

Press on the “Verify Java version” button.

A yellow pop-up screen will appear asking for your permission to run.

javacheck2

I choose to press on the “Run this time” button  photo puh2.gif After you pressed on either button, some stuffies will go on on your screen, if Java is sucessfuly installed you will see this screen:

javacheck3

And you are done  photo thumbsup.gif
