Disabling Power Management

Asked by Murukesh Mohanan

I happen to run Ubuntu Karmic from an USB hard drive on my laptop. As it happens, every time something happens to the power (plugging in / unplugging) it seems that the connection to the drive is reset. At any rate, Ubuntu seems to lose sight of the drive, and fails, or rather nothing but a series of errors happens, and no command can be executed. Now, once I guessed what was going on, I took care to let the power supply remain uninterrupted. But recently, when I tried to upgrade Karmic to Lucid Beta 2, using the update manager, the update manager disabled power management while upgrading ACPI Support, with the same result as when the power supply gets interrupted, causing a mess of the upgrade process. Is there anyway I can disable this power management permanently? Or disable it from starting after a reboot?

Hi :)

Perhaps both. Try going up to the top taskbar and click on

System - Preferences - "Power Management"

to see what options it gives you in there. Also try

System - Administration - Services

to disable anything that is automatically started up at bootup. On my machine i had to untick bluetooth stuff even tho i have no bluetooth hardware.

Good luck and regards from

HI again :)

Err, Lucid is not an upgrade at the moment. It is still a beta release and only really for testing purposes. It is worth keeping your main install as Karmic because it is still the latest stable release. Perhaps set up a dual/multi-boot with Lucid. The official release date of Lucid as a stable release is still about 3 weeks away.

Thanks for your reply. I know Lucid Beta 2 isn't an upgrade, but I'm used to my computer failing at crucial times, so I don't mind testing Lucid.
To get back to my question, I tried your suggestion, but the only available option was in the Startup Apps,and that was for GNOME power management, which is, I assume, simply a tool for setting options. Disabling that didn't do any good (or any harm either, for that matter). I Googled, and tried out Boot-Up Manager, which enabled me to disable ACPI support, but not the power management itself. I found that out to my cost when I tried to uninstall acpi-support (again, to the previously described results). I think stopping acpid might do the trick, but BUM tells me it isn't launched at startup, so something else must start it. So what does launch acpid? Any ideas?

Regards,
Murukesh
