When I first installed Ubuntu I updated it fully with the update manager and then installed the driver for my Radeon HD2400, which caused me no end of display problems... In the end I tore the thing down and did a re-install. No biggie since I'd not done anything with the machine other than the initial install.
To cut a long story short I believe I've pinned this down to the updates:
Is it possible to remove these from the update manager so that I don't:
1. keep getting the reminder to update and
2. accidentally update with them!
