Disabling Bluetooth/Webcam on EeePC 901 at Boot Time

I am using Arch/LXDE on my EeePC 901, and I have installed the acpi-eeepc-generic package from AUR to get hot-key functionality.

Since I rarely use them, I would like to have the default start-up settings as bluetooth/camera disabled, but cannot work out how to do it.

I have tried disabling them from the BIOS, but something in acpi-eeepc-generic seems to overwrite these settings. Commenting out the "BLUETOOTH_DRIVERS" and "CAMERA_DRIVERS" in acpi-eeepc-generic.conf seems to stop this happening for Bluetooth, but the camera setting is still overwritten to "enabled" and continues to be switched on. If I disable loading of the eeepc_laptop module, the BIOS settings remain unchanged.

I have also tried putting the command line disabling code

echo 0 > /sys/devices/platform/eeepc/camera

into various autostart folders, but also without success. It works once, then re-enables on subsequent boots.

I would be very grateful if anyone has any advice.

Thanks in advance.

Have you tried blacklisting the module loading the camera?

How about /etc/rc.local? Your commands will run at every boot.

Blacklisting "uvcvideo" certainly works to disable the webcam.

Something is still overriding the BIOS enable/disable setting to enable it at every boot. I suspect acpi-eeepc-generic. This is not a problem though, unless leaving it enabled increases power consumption.

I did try putting the code above into rc.local, but it worked first time, but not on susequent boots. Curious!

Many thanks for your help and advice Dala and Ilya
