[laptop-mode] Tweak laptop-mode for SSD-disk

[rancor]

Hi all!

I'm using Xubuntu 8.04 and it's default installation of laptop-mode on a Acer Aspire One that has a 8Gb ssd-disk.

I'm trying to figure out all possible ways of minor the wear of the ssd and because the disk is smal the wear increase and it's theirfor important to write as less as possible to the disk.

I think it may be intersting to change the default configuration.

I just started on this track. I have figured this out at this time.

CONTROL_NOATIME=0 -> 1

I'm thinking of the *_HD_IDLE_TIMEOUT_SECOUNDS, *_HD_WRITECACHE and how the pdflush writes from memory to disk to make it only write after the dirty_exprire-timouts.

I need help to find the optimal settings

Best regards rancor
