Comment 8 for bug 1159140

And again, still present in Ubuntu 13.04 final (amd64): The computer booted flawlessly 6 times into the livecd, but when shutting down the last time, it froze stilly being in Unity. The next two times, it crashed already during boot.

This is something, I already realized the last times: When the computer crashes once, the probability is much higher, that it crashes the next boot, as well. Booting into Lubuntu 12.10 worked without a problem.

Maybe this is related to the Intel graphics driver? This is obviously still not working properly in 13.04, as Unity is incredibly slow, making the computer practically unusable with this desktop.
