xserver keeps crashing on my general user account both in unity 3d and 2d. It doesn't do it on the guest account.

That's why I want to reset / rollback everything xserver related, hoping this is going to fix it.

Most answers on this involve sudo dpkg-reconfigure xserver-xorg. However, this does nothing for me (generates no output) and I read in other forums, that it's deprecated.

So, what's the current way to reset all xserver / xorg options; what's the alternative to sudo dpkg-reconfigure xserver-xorg ?

Thanks

Edit: X crashes during work, not before login or so. And the effect of a crash is, that I get thrown out of the session, not a freeze or machine crash.
