Can't hear anything

So, all of a sudden I couldn't play music using Rhythmbox. It would open, I would click on a song and it would say it was playing, but nothing happened. The track clock stayed at zero.

Thanks to this link on the ubuntu forums, I think I have it sorted.

System->Preferences->Sound and changed all the options to ALSA. This has resulted in being able to hear music at the same time as being on the internet etc. Tracks take a couple of seconds longer to start than I am used to, but I'll monitor it for a bit and maybe look at a couple of other steps when I am not busy.

Flocking marvellous

Just installed Flock 2.0 beta 2. No problems except it didn't pick up my flash plugin.

Thanks to this forum page, I did the following and all now works:

go to ~/.flock and
ln -s /usr/lib/mozilla/plugins plugins

I used the first option.

Upgrade to Hardy Heron

With my essays for the year out of the way, it then became time to upgrade to Hardy Heron. Since the previous upgrade went so smoothly, I decided to do another upgrade rather than a complete reinstall.

The upgrade took about two and a half hours: an hour to download and then the rest to update. If I didn't have Tex installed, I think it would have been considerably faster.

Problem: Wireless did not come back up :-(
The hardware driver wizard popped up and recommended the Broadcom B43 driver. After some initial reluctance (I have previously spent days trying to get wireless to work) and some searching in the ubuntu forums, I decided that this was probably the simplest option. Plugging in the trusty Cat 5 ethernet cable and clicking 'enable' meant that the driver was downloaded. A quick reboot and all was in order.

Alternative solutions can be found here and here and here.

It is possible that if the bandwidth via this driver is worse than I am used to I will go down the ndiswrapper route instead, but for now this will do fine.

What have I noticed that is different?
Firefox is now a late beta of version 3. Seems rather nice, particularly the list of pages that comes up when you start typing in the address bar. Needs more exploration before I can say much more about it.

New icons for OpenOffice documents. A small change, presumably OpenOffice has moved up a version too.

I'll report back on anything else I notice later.

Repartitioning went fine. No problems at all.

The update to Ubuntu Gutsy Gibbon also went very well, with the wireless connection coming straight back up. Just a few niggles to sort out:

1 - The mozilla thunderbird icon disappeared from the quick launch tray. Easy to reinstate.

2 - The clock settings went very strange. This is due to the machine dual booting with windows and both operating systems trying to set the computer's hardware clock to British Summer Time. Resolved in Linux by unchecking the box marked 'use UTC'

3 - Flash. I've been using the flashplugin-nonfree package. The package was still installed, but flash wasn't working. Uninstalling and reinstalling this package in synaptic got flash working again, but the next reboot brought the same problem up.

In firefox, type about:plugins into the address bar to see what plugins are installed. I found three different versions of flash installed. Made note of the dates of each version and went looking for the older versions to delete them.

The file that flashplugin-nonfree gets is called libflashplayer.so. Likely places to find it are in usr/lib/firefox/plugins, myhomedir/.mozilla/plugins, usr/lib/flashplugin-nonfree

This last one was the most recent version. Deleting the other versions fixed the problem.

Backing Up and Upgrading

Today I'm using a Dell Inspiron 1300 laptop running Ubuntu 7.04 Feisty Fawn. The object of the day is to end up with it running 7.10. Since 8.04 is released in a few weeks, I'm intending just to do an upgrade, not a complete rebuild.

The story so far:

Problem 1:

The software updater has been telling me for months that the upgrade is available, but that there isn't enough space on the root partition to put the files needed to upgrade. Fine, no problem, I'll repartition.

Problem 2:

Not being particularly confident with partitioning, I decide to do a complete backup of my home directory onto DVD+R. Several days ago I ordered some DVDs and they have now arrived. So, how to burn DVDs. The Ubuntu Forums suggest Gnomebaker so I download it and try to burn a DVD. It won't burn because of problems with the number of levels of embedded directories (see thread). I download K3B and try again. It all works fine.

Repartitioning:
I have a livecd of GParted.
The extended partition that Ubuntu lives on currently has a 4GB ext3 (I think) partition for /, followed by a swap partition, followed by a 60GB or so /home partition. In order to upgrade, I need to move and resize /home, move the swap partition and increase the size of / to about 10GB, to allow for future upgrades etc.

Here goes.
