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!

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

This command for the Fedora versions from 22:

dnf install xscreensaver-base xscreensaver-extras xscreensaver-extras-base xscreensaver-gl-base xscreensaver-gl-extras

After a while you will be asked if you want to continue, press

While I am not a fan of the Matrix movies, I do like this screensaver. It just makes me feel more geeky photo heart.gif!

I found the code for installing the screensavers here.

How to stop Fedora 20 from being slow, freezing and giving black screens.

Last Saturday, I bought a new netbook and tried to install Fedora 20 on it. It was quite an interesting experience, if I had to describe it in two words, I would call the entire experience pure horror. I installed Fedora quite some times, I stopped counting after the 5th install  photo shutup.gif

I fucked up the couple of first installations by using an usb stick which I previously used to install Lubuntu and I didn’t see any harm in NOT wiping the usb stick clean first  photo emo.gif I just  re-used it with Fedora usb creator. I am not going to bore you with the details, but let’s just say I have learned that when creating a bootable usb stick, I should wipe it clean first photo bloos.gif

When I finally managed to install Fedora 20, I noticed it was slow, it would freeze especially during multi tasking, and eventually I would get a black screen that would last 20 seconds. The culprit being my Radeon HD 8280 videocard  photo piangry.gif

I managed to solve the problem, and of course I am sharing my solution with you  photo picool.gif

The usual screenshots are missing, I didn’t dare to take them while solving the problem. I was too afraid my system would freeze. Before you do this “how to” make sure your system is updated! (You do this by typing “yum update” in terminal).

Here we go:

Go to this site and download the drivers.

amdcatalyst
(Yes, I know you can use the “wget” command instead. But when I used it, I couldn’t see when the file was finished downloading and therefore couldn’t unzip the file because it probably wasn’t finished downloading.)

After the file has finished downloading move it to your home directory (in my case it was /home/roja/) so it looks like this.

amdzip

Why you ask? Well it is just to make your life easier, as from now on you only have to copy and paste the following commands  photo nodding.gif

Fire up terminal. Log in as root, you do this by typing:

su

After you have typed your password, type:

unzip amd-catalyst-13.12-linux-x86.x86_64.zip

Then type this:

chmod a+x amd-catalyst-13.12-linux-x86.x86_64.run

Now type this:

yum install gcc binutils make kernel-devel kernel-headers

When this process is finished type:

./amd-catalyst-13.12-linux-x86.x86_64.run

The drivers will be installed, at some point an installation wizard will appear, you can click on “agree”. When asked choose “automatic installation”.

When the installation was finished I got an error report, I chose to ignore it  photo clown.gif Then a window popped saying I had to reboot, which I did. After the reboot, Fedora was fast as lightening and the black screens were gone  photo cheerlie.gif
