[Asus M51Sn] Ubuntu crashing 3+ times a day

[Teo]

Ubuntu has lately become unusably unstable. It is even worse than Windows Vista.
At any moment, suddenly the whole system freezes, or compiz starts consuming 100% CPU, or xorg crashes, or the desktop becomes a mess, or any other berserk behavior that redners the system completely unusable and forces you to switch power off.

Working with Ubuntu has become a hell.
I'm writing bug reports almost 3 times a day about all sort of bizarre system crashes, which are apparently different every time. This is ridiculous.

Did these issues start happening after a recent release upgrade or applying updates?

[Teo (teo1978)]

I don't know, I get automatic updates almost daily, so it's hard to tell.
It certainly didn't happen so often a few months ago, and never or almost never on 12.04.

Just one more issue of these: https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1165767

How can priority be ONLY HIGH?!?!?!?!?!?!?! It doesn't make any sense to waste a minute of time and effort doing anything else in Ubuntu until this is fixed!
I don't even see the purpose in having new releases if this kind of issues are not fully eliminated.

[Teo (teo1978)]

By priority I meant "importance"
