Bug#521279: Bug#521280: acpid does support netlink, so the problem only affects thinkpad-acpi
Hi, I was just wondering, why the Thinkpad special keys don't work when I use a Debian kernel instead of my home-grown one and I stumbled over this bug report ... Well, I just looked at the most up-to-date acpid, and it supports netlink. Therefore, the issue is just that thinkpad-acpi wants you to get hotkeys from the input layer since kernel 2.6.23, Fair enough. But who gets them? and now finally the borrowed time is over in Debian installs, with the procfs event delivery being shut off. Which leaves users out in the cold. What I wrote about a thinkpad-apci backwards compatibility mode was slightly incorrect... teaches me to trust memories over one year old about stuff I never had to look back at, before writing something. The non-hotkey events go over netlink, yes. But hotkeys go only over the input device, where they belong, and there is no driver switch to mess with that. That's wrong. The default as of 2.6.31 is still to deliver them as both, input events and ACPI events (see the `hotkey_report_mode' parameter of thinkpad_acpi). But the ACPI events are only delivered through the legacy interface /proc/acpi/event and not through netlink. This means that all configs that use acpid to process thinkpad-acpi hotkeys will break, and need to be ported over to HAL or something else that binds to input devices. You are kidding, right? You don't seriously suggest that I have to install HAL, D-BUS daemons and what not to be able to hibernate or switch WIFI on and off. I think these bugs can be tagged wontfix, and we just deal with it as the usual perils of using unstable and testing. It is probably a good idea to leave them open in the BTS for a while, in hopes that people will read them before filing more bugs. Thanks for that. I don't think it affects any Debian standard config, but it will affect most of the local configs by end-users. I would like to use a Debian standard config, however there doesn't seem to be any alternative to acpid handling these events (HAL is _not_ an alternative). So what is the standard? I haven't found any daemon that listens to input events and executes actions on them, like acpid does. The only thing available is inputlirc, but that just routes them to a socket which doesn't really gain you anything. So either acpid is extended to also listen to button events, or a daemon is provided, that does this. Until then, the only alternative is to support /proc/acpi/event so acpid can be used for the extra buttons. Cheers, harry signature.asc Description: PGP signature

Sorry, here's the relevant information: Thinkpad T42p Linux 2.6.31 acpid 1.0.10-2 acpid from testing/sid just works fine on my x61s. Acpid can handle button events, but it only defines a handful of them. So either you only use those or it works differently on x61s. See #521280. I've added more information there. As long as acpid is not fixed, users who depend on this functionality are left out in the cold and there is no alternative (and please don't mention HAL). So I think, until then, Debian's Linux kernel should support the legacy /proc/acpi/event interface. Cheers, harry signature.asc Description: PGP signature

Could anyone enlighten me please, where these events are to be found? acpid does not just read the netlink inteface but also the input layer and thus is *supposed* to also get events coming over an input device. You can use kacpimon to try it out. I very much doubt it processes input events like KEY_FN_F1, or KEY_BLUETOOTH by default... and it shouldn't, either.
