The installer still doesn’t support LVM. To be able to install Ubuntu on my LVM partitions I had to follow the steps described in one of my previous posts.

Previously I installed the i386 bit version of distributions on my laptop although it is a x86_64 system. But this time I went for the amd64 version.

You can check if you really have a 64bit processor by checking if there is a “lm” flag for your processor:
$ cat /proc/cpuinfo | grep lm

Using the 64bit version gave some problems, but they are all fixed now:

thunderbird-lightning

The lightning plugin you can download from the add-ons site of thunderbird is the i386 version which doesn’t work with a x86_64 thunderbird. Ubuntu provides a lightning package but this contains some old version. Luckily you can find the x86_64 xpi here: http://releases.mozilla.org/pub/mozilla.org/calendar/lightning/releases/0.9/contrib/linux-x86_64/

sun javaws

The sun javaws isn’t available for x86_64. The openJDK version is available but not all java applications work with that Java WebStart. You can manually install the i386 version of sun-java6-bin:
sudo apt-get install ia32-sun-java6-bin
You can now find the working javaws in following directory: /usr/lib/jvm/ia32-java-6-sun-1.6.0.10/bin/javaws

BTW … Fedora 10 will be released in 18 days
