Well, I upgraded my home computer to the latest 64-bit Ubuntu version. I can start by saying that I am not enjoying 'Unity" as yet. This could be because I have used Gnome for so long, but I will give it a couple of days and see if it grows on me.
The second problem is using an ATI GPU with Boinc. It just doesn't work "out of the box" with the default Catalyst and BOINC installs. I have added the "boinc" user to the video group etc but at this stage it just doesn't recognize the GPU.
Edit: I forgot about this little piece of advice that I mentioned in a previous post:
In /etc/default/boinc-client set the user to "root"
# The BOINC core client will be started with the permissions of this user.
BOINC_USER="root"
I'm now just battling to find work for the GPU as DNETC is offline, this card doesn't meet the requirements for Milkyway, I still can't get PrimeGrid to run due to an unresolved issue with the AMD SDK/OpenCL ... and I don't like Collatz as it renders the PC very slow and unresponsive.
