Description: wmpower is a Window Maker dock application for linux allowing the user to graphically see (and set) the power management status of his laptop. It supports both APM and ACPI kernels, plus it interfaces directly to toshiba hardware (but should work with every laptop).

binary?

I'm having trouble compiling this, can i get some sort of binary (rpm deb or even tgz)
binary?
posted by Noberasco Michele (logged user) - 2003-10-08 03:00:32

I could, but this bynary would depend upon the libraries I have installed on my machine, so it may or may not work on your system...

If you describe your compilation problems maybe I can help you solving them. I would like wmpower to compile on every platform ;-)
bsd support?

Should or does it work on laptop that has *BSD?

Actually, I don't know. Never tried / got feedback about. Want to try it? I'm of course interested in adding support for the *BSD family...

compilation problem
posted by Noberasco Michele (logged user) - 2003-11-28 05:31:13

Strange problem... I have no function tosh_get_info in my code. Either you have a corrupt package, or you are using some strange kernel version. Feel free to contact me via private e-mail.
No readings
posted by DJ_Grijander (anonymous) - 2003-12-08 21:06:36

I have compiled and installed the app, but I get no reading at all (it starts up but that's all). I suspect it has something to do with the "strange" names that my ACPI devices have. For instance, my battery is named C19F, the ac_adaptor is C1A2, and so on. Could this make wmpower not to open the right files? I have looked at the source files to try and replace the names, but couldn't find them... Thanks for any help.

You have to look into src/power_management/acpi/libacpi.c

If you provide me with full path to your /etc files, I'll add them into wmpower source code.
Paths to ACPI devices
posted by DJ_Grijander (anonymous) - 2003-12-11 18:37:44

Thanks for the answer. These are the full paths to my devices in my Compaq Evo n600C:
/proc/acpi/battery/C19F (primary battery)
/proc/acpi/battery/C1A0 (2nd battery)
/proc/acpi/ac_adapter/C1A2 (AC adapter)
/proc/acpi/thermal_zone/TZ1 (thermal zone)

Following your indications, I have tweaked libacpi.c using these values and I have got battery levels and temperature readings. However, the fan indicator doesn't work yet. I have 3 directories under /proc/acpi/fan:
/proc/acpi/fan/C1F6
/proc/acpi/fan/C1F7
/proc/acpi/fan/C1F8

I think they are all related to the same (and only) fan, but they represent 3 different speeds. I haven't found anything to tweak for the fan in libacpi.c. Am I missing something?

Hi DJ
Sorry (again) for my (usually) late reply...

Sorry if I bug you, but I need the path to the files in those dirs, too, and (if possible) also a cat of them so that I can see their contents. Or you could just send me your tweaked libacpi.c instead... You know, I tend to give credits for contributed code ;-P

Regarding fans, I never heard about a setup like yours. I always saw only one entry per battery... Can you send me a cat of all the files in those dirs? Also, can you tell
me your machine name, and wether it uses some custom ACPI patches?
nearly 100% CPU use after compiling kernel 2.6.x
posted by yamakawa (anonymous) - 2004-01-30 11:58:02

Thanks for your efficient program!

I have only one problem with it.
I noticed that since I moved to 2.6.x version kernel, my laptop would be unresponsive first to input from keyboard then to that from mouse and almost be freezed with the fan fully running. I then managed to investigate this issue with top, which showed me wmpower uses over 95% to 99%. Usually it uses around 5%.
The situation is the same, after rebuilding with the new kernel and C library etc.
Do you have any idea with this?

Regards,

Sorry, I forgot to mention this. Above mentioned happned right after the kernel compilation has done and returned to the prompt.
100% CPU use under ACPI
posted by martint (anonymous) - 2004-02-05 16:05:40

I use the default kernel 2.4.21-0.13mdk. At first the fan/temp didnt work. I then added append="acpi=on" in /etc/lilo.conf.
With this setting the temp monitor worked, but I also experienced a very heavy cpu load!
The 100%CPU load-problem must be related to the acpi support.

Hi Michael.

In order to set power management stuff, wmpower needs root access. There is no way around it. You should either run it as root, or setuid the executable. If you are only interested in seeing the status (not changing it), try the -no-meddling command line option.

nearly 100% CPU use after compiling kernel 2.6.x
posted by Noberasco Michele (logged user) - 2004-02-16 04:09:22

2.6.x kernels are quite different from 2.4.x series, and still very new. For some time yet, something will work better, something equal, something worse than in the prev series. You belong to the 3rd cathegory I fear. I myself experienced serious problems running 2.6 kernels until very recently. This because laptops have most of the strange hadrware you can find, and supporting it all is difficult. Thus try and be patient for the time being. Accessing the /proc/acpi interface is very resource intensive for some hardware (even on 2.4.x series), and there is no way to circumvent it other than using the '-u' command line option to set a higher polling interval. Feel free to provide me with additional feedback, though, you can find me directly at michele.noberasco@tiscali.it

Hi Michael, sorry for the overlate reply.
What you are reporting is really a non issue, as wmpower needs root privileges to set power management stuff.

Uhm... just figured out the issue. It is now fixed in CVS... expect wmpower 0.3.2 to work ;-P
