Hi all Well, I got linux on my new laptop and got all the hardware working. I wound up putting slackware on and not Fedora, since the performance of Fedora on the laptop was extremely slow and I couldn't figure out why. Yes, I checked the CPU frequency scaling governors and they were set to performance, but it still ran slow. Anyway, I got slack on and it's running fine, except for ACPI. I can't get the regexp for some of my events correct. What I want to do is for it to start laptop mode when the AC adapter is unplugged, and to stop laptop mode when the AC is plugged in. I've gotten it partially working--it will stop laptop mode when the AC is plugged in. However, I can't seem to get it to start laptop mode when the AC is unplugged. The relevant lines from my /etc/acpi/events/events.conf are: event=ac_adapter.*00 action=/usr/local/bin/startlt event=ac_adapter.*01 action=/usr/local/bin/stoplt Startlt and stoplt are custom scripts I've written to turn on laptop mode and set the correct HD parameters for standby and such, and to adjust the powersave governors correctly. It's the first event that doesn't work, and I'm stuck as to why. I've tried everything I could think of, including putting the entire text of the relevant events in--but if I do that then none of them work. events.conf is a file I created to override slackware's default acpi-handler.sh script, which doesn't work properly on my machine. Can anyone help here? The complete text for both events is: ac_adapter AC 00000080 00000000 ac_adapter AC 00000080 00000001 The first event is what is generated when the AC is unplugged, the second is what is generated when it's plugged in. The only thing different about them is the final digit, which is what I'm trying to work with. Can anyone help with this? If worse comes to worse, I'll use APM, but I'm not sure how good this laptop's APM support is as it was primarily designed for ACPI. THX
