I have read the cautions in SWSUSP and SUSPEND2, and wonder if anyone is actually using either of these on a Laptop?
There seem to be so many caveats, (a) stop devices before suspending, unload drivers (b) USB wont be there when you come back (c) and on and on.
That I have to wonder how useful either of these actually is.
If I were trying to put this on MY machine I would just do the experiments, but this is for a friends machine that I am setting up, and I would rather NOT install this stuff at all than give him something that would cause more grief than help.

I don't. When I do - either the laptop won't wake up again (bad) or it will come back and I have to ctrl-alt-F7 to get back to the gui - and any USB devices have to be unplugged/replugged.
I don't find it very useful.
What also is annoying - I'm suppose to be able to hot swap stuff in my expansion bay (Thinkpad T20) - by unmounting it if it is a volume, and then (as root) eject > /proc/acpi/ibm/bay first.
However, if I do so - I get a stream of IDE errors on the screen, and I need to reboot. So I basically have to power off to switch devices in the bay (not a big issue - I very very very rarely need to do so - in fact, most of the time, I just have the travel bezel in the bay and no devices, let alone wanting to swap).
If there is a laptop maker truly dedicated to Linux - such that they hire kernel programmers to make sure thinks *just work* as well as they do in Windows - they just might get my business. But they would also have to make a 3 button mousepad like IBM does :p

We might be able to give specific advice if you gave more specific details: make, model, output from lspci, the "System Information" stanza from dmidecode, etc.
Have you checked Linux on Laptops or TuxMobil? If it's an IBM/Lenovo, have you tried thinkwiki?
We aren't going to do all the work for you, and most of us here aren't mind readers.

I do use, without any problems at all. It's a centrino notebook, with intel video and wireless.

I'm not sure if my FC6 Dell is going to Sleep or Suspend when I close the lid, but either way it works. I've had no problems with it whatsoever. USB works, wireless and wired connectivily works. No problems.

Thanks for all the responses. No one seemed to mention SWSUPS vs SUSPEND2. Can I assume that you all were using the SWSUPS that is in the kernel source?

I'm using suspend2 on my laptop (kernel-suspend2 and associated support rpms from atrpms). I always suspend to disk and mostly this works well, though recent kernels seem less reliable than earlier ones. Wireless networking and lirc need restarting after a resume, but the suspend scripts has hooks to do this. Graphics, sound and the USB mouse all work fine after a resume (even if the mouse is inserted between suspend and resume).
'Less reliable' above means that the suspend process occasionally aborts or hangs, and seems to do so more than when I had FC4 on the same machine. But I've not seriously tried to work out why.
Regards,
Chris

I use suspend extensively (both to ram and to hard disk). I've only noticed problems with network connections (both LAN and WLAN because DHCP doesn't re-run on waking up) and sound (though that deals with a bug in Flash). All other things seem to keep working. My USB mouse continues to work during suspends. I don't have any specific problems with drivers, but I don't have any high tech graphics card which appear to cause more problem (just a generic Intel integrated video card).
Mostly the functionality will all depend upon the hardware within the computer.
Hope this helps a bit.

Sorry, I'm actually running Kubuntu on my laptop (I run FC on everything else!), but I do the same thing. I have a plain vanilla install, with suspend and hibernate controlled via Laptop Power settings in the KDE Control Center. Hibernate is set to activate upon closing the lid, and it works. Yes, wireless does not reactivate automatically, but that's no big deal. The machine will suspend after elapsed time while running on battery. My machine btw is an ASUS Z3300. Peter

I use it from time to time with FC5 on an IBM thinkpad Z60m - works flawlessly.
