I had to back off 13.04 due to the kernel suddenly not supporting 
vgaswitcheroo properly and this meant I could not get my hybrid 
AMD/Intel graphics working properly. Which meant hideously long first 
login, a weird looking desktop and freezes. By logging out and back in 
again it would work reasonably well though.

Also apparently the broadcom drivers are botched, could not add any new 
wireless configurations to the existing.

My "cure" was to return to 12.10, others suggested up- or downgrading 
kernel and so on.
