The switch from XP to Ubuntu has gone just fine so far. There are a couple of things that I'd like to work out. One is that I can't seem to connect to my office's SSL based VPN which uses Java. I have the 1.6 JRE from Sun installed and configured but, when I connect to the office VPN, it just freezes up Firefox.
I also need to try the proprietary NVidia Geoforce graphics card driver. The screen transitions and scrolling with Firefox seem pretty jerky without it.
