Suspend/Resume broken again (Hardy+1420n)

[aidave]

For a while there, suspend/resume was working fairly well. About 1/5 times it would not resume. Now it is more like 2/3 times it does not resume. This is getting frustrating as depending on a functional laptop is important for my work.

Does anyone know of a way to debug/investigate these resume failures? It seems we need a guide to dealing with this issue.

i dont know much but just curious, how big is your swap partition?

8.42 GB,
my laptop has 4GB RAM

What would be the ideal size?

[sam_delta]

you definetly have enough SWAP, as i told you before, i dont know much, but if you tell me which video card you have, ill do my best to research on your problem, ive heard that video drivers might be a factor for this,

It comes with an NVIDIA card...

Do you know of any logs that are created when suspending and resuming?

[sam_delta]

check out system>administration>system log, ,, and find the date/time when you suspended/resumed

also, after doing some research, are you using propetary drivers?
here are some fixes i found, havnt tryed them but might be usefull to you

i believe that suspend/hibernate works fine with the open source "nv" drivers, but here are some fixes for propetary drivers

Note: those links are some of the answers that i got from googling "ubuntu suspend with nvidia", i duno if they will work, you should research a bit more for fixes for your specific drivers

personally i would research on a specific fix for the driver you are using.
