hello Bernhard
(this is my first post through gmane.org so i hope it will be successfull and i don't know anything about the result :-)
Is there someone to share his experience using acpi with kernel 2.6.(6) and higher?
on my notebook (sony-vaio pcg-grx-316mp, http://www.impressionet.ch/vaio-linux/) i'm using acpi since the 2.4-series-kernels (using acpi-patches) and now also with 2.6.6/2.6.7. acpi is nearly required on that device because otherwise irq-routing etc. won't work well and firewire for instance won't work...
not all sleep/suspend-states are supported, some of them do crash _really_ hard. i suggest you for testing which states are supported to have a look at
http://acpi.sourceforge.net/ especially http://acpi.sourceforge.net/documentation/sleep.html and also http://acpi.sourceforge.net/documentation/index.html for processor-states and battery etc.
you can then easily test if a state works fine using the proc-in- terface:
cat /proc/acpi/sleep # should output supported states echo $state /proc/acpi/sleep # should put the computer in specifed state.
once you've worked out, which of them work, you can use various tools to interfere with the system. i use "klaptopdaemon" which provides a taskbar-applet for kde in which you can do various acpi-adjustments like changing state or define what's happening when closing the lid.
hope this helps,
kind regards,
Pascal Mainini
