Today I upgraded to -6 which disabled the sleep button on my (old) HP Omnibook 6000, at least on console. Haven't tested if it still works from X, though (xfce Desktop).
With -5 the sleep button functioned perfectly from console and from the xfce Desktop. After downgrading to -5 again, everything works fine again, so it must be the changes between these two versions. Before downgrading I tried to revert the change in /etc/acpi/events/sleepbtn manually and and stop/start /etc/init.d/acpi-support, but that didn't have any effect, so I guess there have been some more changes (or I forget to restart something else?). The changelog led me to this bug number which I guess is the culprit, so I hope this is the right place to post this issue. Maybe you can provide a workaround, otherwise I will be staying with -5 for now. This is a fairly basic lenny installation, just base and some selected additional packages, nothing custom. If you should need more details, I can provide them later (at work right now). Hope you can help Kruno -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
