Viewing Embedded QuickTime Movies via Firefox on Ubuntu 2

I was at Apple’s website last night and eager to check out the latest stunning aluminium unibody MacBook, and it was then I realised that my Firefox (on Ubuntu) doesn’t have the ability to play Apple’s de facto online streaming media – the QuickTime movie.

I know that MPlayer has a plug-in, “mplayerplug-in” (a Mozilla browser plugin to allow playing embedded movies on Web pages using MPlayer.) for Firefox for dealing with this problem so in wasting no time I type the followings in the terminal:

sudo apt-get install mplayer mozilla-mplayer

p.s. You might have to enable the “multiverse” repository first in order to install all the required packages.

After the installation, I restart the Firefox for the MPlayer plug-in to kick in, and I was able to watch that embedded video showing how Apple design and produce the beautiful 13′ MacBook from a single aluminium block – I’m very impressed I must say.

Firefox Problem After Upgrading to Ubuntu 8.10 (From 8.04) 0

After the smooth process of upgrading my Ubuntu from Hardy Heron (8.04) to Intrepid Ibex (8.10), I happen to notice my Firefox (version 3.03) starts to behave differently. For instance, Firefox’s toolbar always returns to the default layout and some of installed add-on icons do not appear even they are functioning properly.

After some trials and errors, I eventually found the culprit that is causing this strange behaviour: Ubuntu Firefox Modifications (version 0.6) add-on. Once it is disabled, Firefox behaves like normal. I suspect a newer version of this add-on is needed for the new Ubuntu 8.10, however I’m still yet to notice any problem after disabling it…

Restarting/Restoring Audio in Ubuntu Without Rebooting 24

Occasionally on my Ubuntu machine the sound/audio somehow stops working, and although most of the time this can be fixed by closing and then restarting the audio programme (or any other service that occupies the audio driver) you’re running. However on odd occasions the audio still fails to work and you might have to reboot the OS in order to get the audio/sound back which is rather irritating.

Here is a quick way of restarting/restoring your audio/sound without rebooting your Ubuntu system, try using the following command:

sudo /etc/init.d/alsa-utils restart

This should restart your ALSA (Advanced Linux Sound Architecture) driver instantly. However, sometimes certain programmes still keep holding on the audio driver even after your restart ALSA. Try the following command:

lsof | grep pcm

to find out the list of open files and close (kill -9) those processes that are still holding the sound driver.
