Upgrade to Ubuntu 9.04 64-bit

Today was the day and I upgraded my home PC (the Athlon X2 4200+ with 8800GT) to the latest version of Ubuntu. As I have messed around and installed a lot of junk, I decided to do a clean install instead of allowing it to do its own upgrade. I had a niggling feeling that getting BOINC and CUDA to work again would be a little bit of a challenge... and was right.
When the new OS booted for the first time, it decided on a generic display driver and as a result decided that 800x600 was the best resolution. Unlike the previous releases there was no option of just turning on the restricted drivers to get everything to work. I had to go and find all the NVidia drivers in Synaptic and do a few restarts to get X to work. Finally got the 180.44 driver on BOINC 6.4.5 (there was no GetDeb option for 9.04, so had to use the old 8.10 version which seems to work OK)
So, after about 3 hours we are up and running again ... except SETI appears to be down :-(
