linux suspend/resume with hal/dbus
I'm starting this thread to get some feedback from people that ideally have first hand experience with linux boxes in their car.
i've been going back and forth between if i want to get a mini-itx system for my car, or use and old laptop. Cost, and features though are making me look at the old laptop as the best route to go, here's how i see it so far
2ghz c7 board+ ram+cf storage ~$250
power supply/startup controller $100 +
nice case $70
pIII dell latitude - ~$100 on ebay, already have one though
power supply ~$75 for a ac inverter for the original power brick then run a normal computer power supply for the 12v regulated my lilliput display needs
using the laptop also has the advantage that my carpc now has its own battery (ignoring the display) so i won't need to worry that much about killing my battery in my car if i decide to use it when the car's off.
I think its also possible to read acpi information with hal so when the laptop gets unplugged (+12 accesory tied into a transtor on the ac inverter's power switch) it suspends, and then when it gets plugged in, it resumes. i'm pretty sure i know how to initiate the suspend, but i'm not that sure about the resume, seeing how the laptop is suspended.
i also know i can get processor temp readings correctly from the dell, monitor the fans, watch the battery level, and give it 2 batteries, so it deffinately seems the best way to go.
how many people out there use laptops for their car pc's and how do you usually handle suspend/resum?
