Ubuntu Unity Video Tutorials

April 21, 2011 in Film, Linux, Ubuntu | No comments

On ubuntuforms.org I saw a post by the user castrojo to two Unity video tutorials made by him. I think that they work as a good introduction to Ubuntu’s new user interface. However, Ubuntu 11.04 hasn’t been released yet, and Canonical says that they will do many changes until then. But I suppose that the basics will be the same, and that they only will add more functionality. Links to the two videos:

When I started Ubuntu 11.04 Beta 2 for my first time, I was really sceptical to Unity, so I changed fast to Ubuntu Classic. But then I gave Unity a second chance and I must say that it actually isn’t that terrible. I miss some stuff, like better support for dual monitor setups, the ability to right click the panels, and the ability add applets to the top panel. But I hope this will be fixed to the release of Ubuntu 11.04.

Three Monitors With Two AMD/ATI Graphic Cards

April 21, 2011 in Hardware, Linux, Ubuntu, Windows | 1 comment

I have two 22″ monitors hooked up to my computer through DVI. But the other day I wanted to try out if it would work with three monitors too. However, my ATI/AMD PowerColor 4870 graphic card has only two DVI video outputs, so I borrowed my brother’s video card, which is an ATI 3650. After plugging it in to a PCI-E bus, I realised that it hasn’t even a Crossfire connector. I did some searching and found out that a Crossfire bridge is only needed when you want to take advantage of the extra video card in games and such, which I wasn’t interested of. Then I hooked up my brother’s 17″ monitor to the 3650 card. The monitor had only a VGA input tho, while the card only had DVI outputs, so I had to use a DVI-to-VGA adapter.

I started with booting up Windows 7, and it worked fine with 3 monitors. However, I didn’t test it for too long. Then I rebooted the computer and started up Ubuntu 10.10 instead, to see if it would work. I had to do some configurations in the ATI Catalyst Control Center, but then it worked there too. However, it worked a bit strangely, almost like its own desktop. The 17″ monitor had the standard panel configuration for a single monitor, and I wasn’t able to drag windows between it and the other two monitors. I didn’t have much time tho, and my brother wanted his card and monitor back, so I never solved that odd problem. Maybe I had to adjust something in CCC, or somewhere else, I don’t know.

To summarize this post: You can use three monitors by plugging in a second (AMD/ATI) graphic card. The card must not be of the same model, or even of the same generation (ATI 4870 and ATI 3650). You don’t need a crossfire bridge. Though, I can’t say if this applies on Nvidia cards too.

How to install KDE on Ubuntu

January 29, 2011 in Linux, Ubuntu | No comments

A few hours ago I installed KDE on Ubuntu, which means that I’m now using Kubuntu. :o It was really easy to switch to KDE from Gnome, since I found 2 guides that showed how. The reason behind my switch to Kubuntu was a mate in my class. He dislikes Ubuntu and wanted me to try out Kubuntu. And so I did. I have tried it out earlier (for a short amount of time), so I’m not a complete n00b in the interface. But I guess I have to use it for a while and see how it is like.

If you also want to install KDE on Ubuntu, check out these two links:

And if you didn’t like KDE and want to switch back to a pure Gnome on Ubuntu:

How to get the android and adb commands to work in Ubuntu terminal (Android SDK)

January 19, 2011 in Android, Linux, Ubuntu | 2 comments

At first, the commands android and adb didn’t work in my Ubuntu terminal. But what I did to get them to work was modifying the .bashrc file in my home folder. It’s hidden so I showed it with Ctrl + H. In the file i edited the PATH lines to this:

#AndroidDev PATH
export PATH=$PATH:/home/teraspes/android-sdk-linux_x86
export PATH=$PATH:/home/teraspes/android-sdk-linux_x86/platform-tools
export PATH=$PATH:/home/teraspes/android-sdk-linux_x86/tools

I can’t really recall what they were from the start, and I don’t know if all lines are needed. But as long as the commands work I won’t touch the lines, because I will just mess something up and end up with trying to fix it four hours.

If it still doesn’t work for you after this change, try to restart your computer.

How to Fix Flickering Flash Videos in Firefox 4 in Ubuntu 64-bit

January 6, 2011 in Applications, Firefox, Ubuntu | 32 comments

For long I have been having problem with flickering flash videos in the Firefox 4 beta in Ubuntu 10.10 64-bit. Today I found a solution, and I have no longer any reason to use Chrome. :)

It seems that the problem with flickering flash videos only occurs with Adobe Flash Player 10.1. So, by installing the beta 10.3 of Flash Player, the problem is now long gone.

I don’t know how you install the Flash beta in the 32-bit version of Ubuntu. But in the 64-bit version you just need to type these lines in the terminal:

sudo add-apt-repository ppa:sevenmachines/flash
sudo apt-get update
sudo apt-get install flashplugin64-installer

I hope this solution works for you guys!
