How well is it working for you, what kind of difference are you seeing on battery life phrakture?

itlain · 2004-10-09 07:07:27

mkdir -p $startdir/pkg/usr/local/man/man8
install -m644 man/laptop_mode.8 $startdir/pkg/usr/local/man/man8
install -m644 man/laptop-mode.conf.8 $startdir/pkg/usr/local/man/man8

This is the only part in which I think there is a problem. My understanding that Arch didn't use /usr/local at all unless it was a locally installed program, ie not a package. I don't have any man pages under /usr/local/man. All of mine are under /usr/man. But it would be an easy enough fix. Now to see if the program makes a difference on my battery eating laptop.

phrakture · 2004-10-09 07:11:02

whoops... sorry - i used the install script for the package to make the pkgbuild and copied most verbatim.....

i apologize for the man page error

Hi. Thanks for the PKGBUILD. Just wanted to say that the config files weren't installed, I had to move them manually from src/laptop-mode-tools-1.02/etc to /etc/laptop-mode. I might have done something wrong though, since I'm new to arch. But I was wondering what exatly laptop-mode does? I thought it as supposed to spin done the drive, but I'm not sure it does. Is there a way to find out if the drive is idle or not?

jerem · 2005-05-17 07:18:31

If the drivee is idle you will hear a noise when it "awakes".

nightfrost · 2005-05-17 07:29:07

Thanks, but I was looking for something more black on white..

nightfrost · 2005-05-17 09:19:15

I realized the config was merged in the script itself... so, nevermind my previous remark on the config-files. It seems to work great

Something's continuously forcing my disk to spin up. I'd wager it's syslog-ng. How do I stop it from writing to disk. I have this in /etc/syslog-ng/syslog-ng.conf

why does one wanna use laptop-mode-tools? what do they provide which the kernel and cpufreq don't?

I do use a laptop as my primary computer, but never used laptopmodes....should I?

nightfrost · 2005-05-17 15:11:27

I only use it in order to get a drive spin down (which I guess you could do with hdparm)- it has some additional features, like caching a certain amount of writes to memory, and then flush everything at once when the drive spins up. You should check the script which starts with the configs in order to see the available features. I don't use it to manage cpu-frequencies though.

phrakture · 2005-05-17 15:37:14

all these tools really do is "echo 1 >> /proc/sys/..../laptop_mode"

I don't use this anymore, I just set laptop mode to 1 in rc.local

laptop_mode doesn't do disk spindown the same way hdparm does. It tells the kernel to hold disk writes for a number of seconds in case there are more writes... so if I wrote 10b, 10b, 10b, 10b, 10b, the kernel would normally write 5 10b blocks... with laptop mode on, it would probably write a 30b block and a 20b block (just making it up as I don't know the "wait time")

nightfrost · 2005-05-17 15:51:23

all these tools really do is "echo 1 >> /proc/sys/..../laptop_mode"

Yeah, that's smart. How about the config, then? Do you still have /etc/laptop-mode/laptop-mode.conf?

And, also, is it really no problem for the drive to spin up & down continuously?

laptop mode is part of the kernel (been around since 2.6.4 or something) - the laptop mode tools simply toggle around the kernel's laptop mode

disk spin up/down isn't an issue, really - it's just that a) this may prolong disk life by a tad and b) prevents extra noise/heat from the laptop

nightfrost · 2005-05-17 16:12:16

but if you just "echo 1 > /proc/sys/vm/laptop-mode", what decides how long the disk will be idle before it spins down?

Oh, that's a relief

be very careful with this... it gets crazy... do it for like 1min max

echo 1 >> /proc/sys/vm/block_dump

this will log to dmesg info about which process is causing the disk spin up

...

the write delay is set in the kernel, but laptop_mode... I have no clue what it's set at....

nightfrost · 2005-05-17 16:44:34

Thanks alot! That's preciely what I've been looking for. I'm gonna try that out next time I'm on battery.

Hi phrakture,

I've tryed the PKGBUILD, but I don't know why the "install -d" doesn't seem to work...

So I've adapted your PKGBUILD (and updated to lates program version) following the install.sh script.

The PKGBUILD now create explicitly the folders, then use install -mXXX with permissions taken from the install.sh. Its longer to create such a pkgbuild but its cleaner.

Here it is:

ummm this has been in the AUR for some time - please check there before posting PKGBUILDs to the forum - this is a very old thread too

Please correct it if I'm wrong,

but _laptop-mode.rcd_ has moved to _/etc/rc.d/laptop-mode_
I'm running _laptop-mode-tools 1.05-1_
