After installing Ubuntu 10.04, Vuze would not start. Reinstalling the libswt-gtl/3.5/java package may solve this problem (thanks to the tips in this issue at launchpad.net). Reinstalling this package may be done by opening a console window and typing: “sudo apt-get install –reinstall libswt-gtk-3.5-java“

First, add a repository that contains Sun’s JRE. You may go to the Synaptic Package Manager and select “Settings->Repositories->Other software->Add” and paste the following: deb http://archive.canonical.com/ lucid partner, or type the following command into your console window:  sudo add-apt-repository “deb http://archive.canonical.com/ lucid partner”.

Second, you should now be able to install sun-java6-jre, sun-java6-fonts and sun-java6-plugin through either Synaptic or sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts.

Third, make sure that you remove the openjdk. In Synaptic remove openjdk-6-jre-lib and openjdk-6-jre.

Finally, set the sun-java6-jre to be your active jre by typing the following in your console: sudo update-alternatives –config java. Then select the right jre (/usr/lib/jvm/java-6-sun/jre/bin/java). It should most likely be “0″.

This does not work right out of the box with Ubuntu. Thanks to Anders S. Lund I found the solution, which was to install an alpha version of Moonlight:

1. Remove the Firefox-VLC plugin: “sudo apt-get remove mozilla-plugin-vlc”
2. Remove previous versions of Moonlght: In Firefox goto Tools -> Add-ons -> Extensions
3. Download the most recent version of Moonlight: http://www.go-mono.com/moonlight/prerelease.aspx
4. In case of sluggish performance, turn of all effects by closing the browser and using the following command: “MOONLIGHT_OVERRIDES=effects=no firefox“

See the following link for more information/troubleshooting.

Mediaplayer/Totem preferences

The fix was relatively simple. It seems as because of some old bug, the Hue in Movie Player/Totem should have been turned off (either to max or min). Now, it seems someone have fixed this bug and the Hue should rather be set to the middle position as illustrated above. Open Movie Player (Applications -> Sound & Video -> Movie Player). Open the display preferences like in the figure (Edit -> Preferences -> Display) and put the slider in the middle position. This did the trick (at least for me).

Error message:
The following packages have unmet dependencies:
sun-java6-plugin: Depends: sun-java6-bin (= 6-15-1) but 6-16-0ubuntu1.9.04 is to be installed
E: Broken packages


To fix it, I removed the java implementation through the following commands (thanks to FrostCake):
sudo apt-get remove sun-java6-jre sun-java6-plugin sun-java6-bin sun-java6-fonts
sudo apt-get autoremove

Then I reinstalled the sun-java6-plugin through the Synaptic Manager. This will also install all packages which the Java plugin depends on.

I have for some time had problems with flash videos in Firefox on my AMD64 Ubuntu machine. I normally use the computer for work so it has not really been that much of a problem. However, I hate not being able to use Ubuntu the way you would expect it to work … A Google search later, I found these simple instructions. Just follow the instructions and you will have flash videos working in no time. If you want to test your flash player on your AMD64 Ubuntu machine, you may check of EpicBattleAxe video above.

By the way, the new Ubuntu 9.10 looks and feels quite good

Fixing it was rather easy. Have a look at the solution provided by M.Srinivasaverman (thanks man!).

Luckily, by disabling IPv6 it was quite easy to speed it up. The steps below should do the trick (thanks to tribaal at the ubuntuforums):

• open firefox
• In the adress bar type in “about:config”
• In the filter bar type in “ipv6″
• Double click “network.dns.disableIPv6″ so that the value turns to TRUE
• Restart firefox

This helped my browsing quite a lot and you might give it a shot if you experience slow browsing in Firefox.

Edit: Adding the Flashblock add on my further speed up loading of pages with a lot of flash. Be aware that this add on blocks flash videos and if you want to see them you have to click on them.

I did not know what to do when I needed to merge and delete pages from two pdf documents. However, a few Google searches later I found pdftk (pdf toolkit) and it was just what I needed. It is easily installed either through the Synaptic Package Manager or “sudo apt-get install pdftk“. I use Linux (Ubuntu) but there are versions for other operating systems available as well, including Windows.

To merge two documents you may use a simple command “pdftk 1.pdf 2.pdf cat output newfile.pdf” and to delete pages, just type “pdftk A=1.pdf cat A4-6 output newfile.pdf” (this will only include page 4-6 in the new document). Have a look at the pdftk web site for more examples.

For some reason I do not bother to dive into, openjdk is hard coded into Vuze as its preferred Java implementation on Ubuntu. When I removed openjdk, Vuze would of course not start. It is apparently a bug (or meta bug) but it is quite simple to fix.

Change one line in /usr/bin/azureus by using “sudo gedit /usr/bin/azureus” and change the line JAVA=’/usr/lib/jvm/java-6-openjdk/jre/bin/java -Xmx1024M’ to JAVA=’/etc/alternatives/java -Xmx1024M’
