APM unusable since 2.4.10
Hello, I have a Mitac 7521 laptop, which is a SIS630 chipset with a Phoenix BIOS and some interesting hardware around. Until kernel 2.4.9 included I was able to suspend to ram and to disk with APM and to have my system back most of the times, and I was almost happy with that. Since kernel 2.4.10, when APM kicks in for anything (even just for turning off the LCD display), the system gets badly hung and I have to switch it off the hard way (i.e. holding down the power button for >4 seconds). For now I resorted to ACPI, but in its current state I loose all suspend and hybernation features I had. Does anybody have experienced with similar problems, and has some more informations to give me about it?

Re: Thoughts on network detection and configuration on Debian
Hi everybody! Many great people provided great comments and ideas to my thought and the picture gets bigger. Another twist is added by the fact that it's holiday time here in Italy, and I have eaten and drunk things that no English words to my knowledge can describe :) You made me discover that my thoughts were limited in may ways; among others I considered ifupdown the main center for profile detection and reconfiguration, and I supposed that all the possible system configurations could be represented by many distinct profiles. The problem gets bigger and involves many (still independent) parts of Debian: apmd, acpid, network tools, pppd, pcmcia-cs, hotplug are some examples of parts of Debian that cause or detect changes on the system and provide hooks to react to them, and more can be expected to be added in the future. Reacting to IrDA discoveries comes to mind, as well as deploying a tool to enable some services based on user requests (take a look to http://reshare.sf.net for an example of a tool to manage such requests. Ready to be added to Debian if needed, btw.). Right now there are utilities to scratch many of the itches related to this, but Debian seems not to have a masterplan to define its behaviour for a system that should react to a changing configuration. Maybe I should retarget my thoughts and start addressing this whole issue? In fact, right now we already have some problems: pppd scripts might need to be filled with `if's checking if other network connectivity is present, and start some network services only depending on if the system is running on AC power or if a given PCMCIA hard drive is present. A DNS or a network route might need to be reconfigured by pppd, pcmcia-cs and network-detection tools. At the current state of things this things, if pushed, can easily lead to a mess. Maybe it's time to design a tool that gathers all notification of the changes that happen in the system and provides the user with a single point to program the logic to react to them, and standardize it in such a way that other parts of Debian can interact with it? With it we could have tools specialized for detection, tools specialized for reconfiguration and a central point that can do the coordination to make them work together. I can easily see that the issue will become more important in the future, as outplugging devices will become more popular and Linux systems will be deployed in environments that require more flexibility. Am I still under the effects of my wonder-lunch (anyone here is invided should you pass in the nearby) or is there some logic in all this? If there is, I'm ready to get to work. Bye, Enrico P.S. In the meantime, we might still like to think about merging efforts to share functionalities with all the network detection tools, and it would still be an interesting work. Unluckily I won't have access to whereami until tuesday so I can't make studies right now, besides proposing to extract the link-beat detection code from laptop-net in a daemon that launches a script when the link goes up or down on a given interface and let users hook their preferred tool to it. -- GPG key: 1024D/797EBFAB 2000-12-05 Enrico Zini <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".

I used to use ifupdown-roaming on Debian/woody, but it disappeared. You can do similar things with ifplugd, waproamd and guessnet: ifplugd will ifup your eth0 when a cable is plugged and ifdown it when you remove the cable waproamd (IIRC) will ifup your wlan0 when you associate with an AP and ifdown it when you get out of range guessnet will help you choose the right configuration if you have more than one (see http://guessnet.alioth.debian.org/) > However, I would like to get some scripts which would set exim's smartserver > to a free SMTP server, etc. Can anybody suggest one (of course, fully > compatible with ifupdown)? ifplugd, waproamd and guessnet solve the triggering and the choosing problems; they don't configuring, though.

I think because everyone has different wishes for detection and reconfiguration: whereami is hard to setup but allows for all sort of weird setups; guessnet integrates well with ifupdown; others ask you a question at boot, and so on.

That would be good. That might finally be a way of putting our efforts together: I could hack guessnet to do some network scan when it sees a D-BUS request, and whereami can be the reconfiguration backend. Let's see when that comes to Debian. Ciao, Enrico -- GPG key: 1024D/797EBFAB 2000-12-05 Enrico Zini <[EMAIL PROTECTED]> signature.asc Description: Digital signature
Detect what is causing the hard drive to spin up
Hello, I've just setup noflushd and finally can enjoy to hear that damn hard drive to spin down after a while it's not in use. However, a few seconds after spin down, to my great frustration it spins up again, resuming that fastidious noise. Obviously, I wasn't doing anything to justify that spin up: I wasn't even touching the laptop. I've already tried to shut down the services that I thought could be the cause for this, but the spinups continue. Do you know if there's a way, like some kernel facility, to track what's doing these disk accesses? I would avoid me some long trial and error, and it would be the definitive tool to use in this investigation: I'd be really happy to use it.

Reducing traffic to XFree86.0.log
Hello, In my efforts to trade disk writes for silence I've gone through a continued narrowing down of causes[1], and I'm now facing with the XFree86.0.log file. What happens is that the wacom driver often complains about not finding the /dev/input/event0 device (ehi, it's USB, it's hot-pluggable, that's fine, why bother?) and the development-stage SiS driver prints debug tracing stuff about normal but unusual events, like the monitor entering power saving modes (doh!). I'd need some way to change the verbosity level in a driver-by-driver basis (silencing wacom and SiS a bit and letting the other parts of X complain undisturbed). However, I couldn't find any documentation on how to do that. Do you have any clues? Bye, Enrico [1] Thanks Jeff for the find tips! However, it seems that there's no better shortcut, like the kernel write log I was hoping to find. :( -- GPG key: 1024D/797EBFAB 2000-12-05 Enrico Zini <[EMAIL PROTECTED]>

Proposal for an infrastructure for systems with multiple configurations
Hello, after some time spent in thinking, design and developing, I've wrapped up a pre-release for a tool that aims to provide a clean infrastructure to manage systems with multiple configurations, like laptops. The software is called stated and is found in: http://people.debian.org/~enrico/stated.html stated is a daemon that keeps track of the system state, reacting to changes. It manages a set of user-defined variables representing the system state; when some variable changes, user-defined code is executed to reconfigure the system for the new situation. Stated can be used to gather all kind of informations like battery charge, LAN network identification, PPP connection status, USB or PCMCIA devices present in the system, etc. in a single place and to run reconfiguration scripts with a more complete knowledge of the situation. stated also provides an interpreter for simple special-purpose language costructs that ease writing complex action scripts. The difference with other programs used to reconfigure a system on the fly is in the approach: stated does not know anything about the system and just holds a model of it in the form of user-defined variables. This makes it generic, providing a level of abstraction upon which it should be possible to easily build handlers for complicated reconfiguration scenarioes. The package, among all other documentation, contains a RATIONALE file with more detailed discussion on the design choices that have been made to come up with it. I make the announce here to gather feedback about the package; if people other than me will find it at least potentially useful, I'll be happy to go on with the TODO, fill in some little gaps it still have and add it to the Debian system. Please let me know what you think about it.
