Greets, I use suspend-to-ram all the time on my desktop-machine as well. Energy-saving and quicker for me ... it works fine.
I use the tuxonice-sources for this, back then it was more reliable with my hardware. Usually the ebuild for tuxonice-sources is some weeks later than gentoo-sources. As I am always curious for the latest stable kernel I often run gentoo-sources inbetween (and think to myself "I can get by without S2R for a while"). Now I have noticed that "hibernate-ram" works with plain gentoo-sources as well. And it does so without a problem. Fine! Is there any real advantage in using tuxonice here? Pls note that I only use S2R, and never suspend to disk .... all the disk-related features of tuxonice aren't important to me. Thanks for your opinions, Stefan
