I changed the affected package - but please change it back if I'm wrong. My reason being, it seems unlikely that this is where the problem lies: I tried installing nexuiz on a friends machine which is also a Dell laptop. It's a different model to mine - the difference is that the mouse does NOT jump around on his computer when playing games such as nexuiz. It works perfectly. Nexuiz is very playable. It gives me the impression that this is somehow hardware, which is why I failed to see how SDL could be affected.
I'm in the middle of exams at the moment, but I will try install a clean ubuntu with no updates and try all the above mentioned games again.
