Most times it takes several tries to log in, the computer crashes and goes back to the login screen.
Often if you log out, and invariably if you try to "switch user", then it crashes: black screen, unresponsive to owt, and also will not come out of suspend or hibernate.
Am getting inclined to give up and try another OS, OTOH, nearly everything works most of the time.
Fedora 12 on a Compaq M2000 laptop.
