I'm using Fedora on two laptops for quite some time now (since F8).
Having used suspend-to-disk very often I can conclude, that I'm not
happy with the performance it shows. Suspending a laptop with just
1GB of memory takes about 30 to 60 seconds here and nearly the same
for resuming. The same laptop on Windows (sorry ;-)) got it done in
about 10 seconds each.
What I did some time ago, was to switch to the TuxOnIce patched
kernels from atrpms. Not only does TuxOnIce show a progressbar (even
with splash if wanted) during suspend and resume, it also handles
the process in the expected 10 to 15 seconds.
Since Fedora patches the Kernel anyway, I propose adding TuxOnIce
It's patched very minimally. The two largest items are execshield
and utrace. Aside from that, patches actually tend to be fixes, not
(also known as Suspend2) into the official Fedora Kernel. It
hurt those who don't use suspend-to-disk anyway but benefits those
Also it could probably rather easy be integrated with Plymouth to
show a nice animation during suspend and resume. (Though that would
be optional :-P)
I think the best option is for either TuxOnIce to get into the
kernel, or to fix the problems with the existing suspend
I hope you take at least the time to consider it for a few moments.
I won't speak for the Fedora kernel team, but I can't see them really
wanting to add this.
