Karmic Koala release candidate

I just upgraded my LG P300 to Karmic Koala release candidate. To be precise, I did a fresh install.

I have /home in a separate partition. I followed my usual Ubuntu upgrade procedure is as follows:

  • Take backups
  • Install OS to a new partition
  • Test it
  • Mount the old /home.

The desktop CD booted no problems. The install went well.

On reboot I ran into this bug. The good news was that moving /etc/X11/xorg.conf out of the way was enough to get the machine booting into X without problems.

Once in X I was able to install the proprietary Nvidia drivers and all has been good.

I decided to convert my home directory to ext4.

This is where I ran into a bit of fun. First of all, I'm a plonker and when I partitioned my disk a while back I created too many primary partitions and did not leave enough space for the one extended partition I created.

Once I had karmic running I decided to backup my jaunty partition, then do some re-partitioning, then copy the jaunty install back into a fresh partition.

Now karmic comes with grub2. One nead thing with grub2 is you can just run:

sudo update-grub

and it does just that, including scanning for other OS'es on your system. This nearly worked for me. Unfortunately, I hit this bug. Probably a pretty rare situation, but would be good if the OS probing could cope with this one.

With a little hand editing of /boot/grub/grub.conf (yes, I know you are not supposed to do this) and fixing up the UUID's in the fstab the old jaunty install was up and running again.

In the course of this I discovered: /dev/disk/by-uuid/

This is a folder with links named by the UUID's to the actual partitions in human readable form. Very handy.

What is new?


I had mixed feelings about the switch to empathy from pidgin as an IM client. I've never been 100% happy with pidgin though, so I was prepared for a few rough edges. I really haven't used empathy long enough to give a fair assessment, but so far it is doing the job nicely.

Added bonuses are voice and video support. Voice also working to people running gtalk within firefox on OS/X.

Update: video also working from empathy on Karmic to gtalk running in firefox on OS/X.

Firefox 3.5

This seems very much snappier than firefox 3.0. I was using firefox 3.5 (shiretoko) under jaunty but that was sluggish compared with the karmic firefox3.5

Pulseaudio airtunes support

Pulseaudio now comes with support for airtunes.

You will need to install: padevchooser, pulseaudio-module-raop and pulseaudio-module-zeroconf.

With these it should automatically spot any airtunes devices you have on your network.

You can then fire up padevchooser, configure the local sound server to 'Make apple airtunes devices available locally'.

Now from the pulseaudio volume control, go to the playback tab and you should be able to select your airtunes device as the sync.

Wow sounds like you ran into a few snags along the way! Overall it sounds like you like the new version. I can't wait to install it.

The failure to boot after install was the only problem a normal human being would have.

update-grub not being able to cope with an OS partition I moved wasn't totally unexpected -- I was actually happy that it worked in the end.

I'm still using Karmic + lots of little things are working much better.

Overall, much snappier -- cpu usage is down -- a couple of apps that were chewing up cpu usage there seem much better behaved now, which helps with overall snappiness.
