Review: The latest versions of fast-moving OpenSUSE, Ubuntu and Fedora make a strong case for Linux on the desktop, but there's lots of integration work to be done.
Eweek takes a thorough look at the three distributions
Under Fedora 8 and OpenSUSE 10.3, my test machine's suspend and hibernate power management functions both worked well. (Suspend sends PCs into a low-power mode, and hibernate saves PC state to disk and turns systems off.)
With Ubuntu, I couldn't get hibernation or suspend working, due to a reported bug in the way that the proprietary ATI graphics driver interacts with the system. Rather than hibernate or suspend, the display of my ThinkPad turned black and the machine hung, requiring a hard reset.
