I've converted an old Gateway laptop into a digital picture frame. Using Kubuntu 10.04 with the background image changing pictures every 10 seconds from an NFS mount. It shows current time/date and current weather forecast. everything works great, looks great; except for one problem: It goes to suspend or sleep mode after about 10 mins!
i checked the bios for any setting for power management...none. Bios version is PhoenixBIOS 84.05. In fact, while in the bios the laptop never goes asleep. But after Kubuntu is running it does, even after changing all power management settings to what i think should prevent this. And since this laptop is now an attractive picture frame, I don't want to leave a mouse or keyboard connected to wake it up. Shouldn't have to...right?
My current power management settings are:
General settings:
Lock screen on resume: unchecked
Let powerdevil manage screen powersaving: unchecked
Before doing a suspend action, wait: 360 min
When AC Adapter is plugged in: Presentation
Edit Profiles:
Actions tab
I changed all profiles to have the same settings.
disable desktop effects, if active: unchecked
dim display when idle for more than: 280 min, Do Nothing
Do Nothing on all others
Screen tab
enable display power management: unchecked
all others: unchecked, 0 min
CPU and System tab
turn off CPU(s): unchecked
CPU freq scaling policy: Dynamic (ondemand)
system powersaving scheme: performance
Any Help?
Thanks
