The sad thing is that I did not get any problem with suspend or hibernate -- nothing significant. Every distribution I threw at it seemed to play relatively nicely with it, including Linux Mint 6 Main (x86 and x86-64), Ubuntu 8.10 (x86 and x86-64) and OpenSuSE 11.1 (x86, did not have time to download the x86-64 variant). The only minor problem with power management that I found while playing with this laptop was the hard drive would constantly grind aggressively upon resuming from hibernation under Ubuntu 8.10 x86-64, although it only occurred occasionally and it did not arise under any other operating systems that I tested.
Therefore I can only give you hypothetical possible fixes here, which may or may not get rid of the issues you are experiencing:
a. Upgrade your laptop BIOS to the latest version. The laptop I tried already had the latest BIOS available on Acer's web site.
b. Give your operating system a swap size of at least 1x the size of your physical RAM. This was how I set up the swap partition for every operating system I installed on the laptop.
c. Reconfigure uswsusp like this:
- Call uswsusp's configuration menu:
Code: Select all
Code: Select all
- "The device node through which uswsusp can talk to the kernel:
Just clear (empty) the input box and hit Enter to use the default node (/dev/snapshot).
- "Perform Checksum on image?"
- "Compress image?"
- "Perform early write out?"
- "Preferred maximum image size:"
Enter a value no higher than half of your swap here.
- "Log level:"
- "Maximal log level:"
Enter 2 again.
- "Encrypt snapshot?"
- "Show splash screen?"
That is about all that comes to mind as of now. I am sorry for letting you guys down.
