Questions[aspire-one](ubuntu)

I just installed 12.04 LTS onto my Acer Aspire One from a USB thumbdrive, and I cannot reboot unless I boot from the USB drive. If I have the USB drive plugged in, it boots, and it looks like the system is running of the HDD (/ is mounted from there, the USB drive is /media/PENDRIVE, everything works fine when I unmount it, etc).

If I reboot with no USB drive mounted, I just get a flashing cursor. It looks like a misconfigured boot loader. The Terminal tells me that grub is not installed ... so just how does Ubuntu boot these days, and how can I make the HDD bootable?

I have Acer Aspire One D257. The wireless does not work at all when using Ubuntu 10.04 . But it works properly when using Ubuntu 11.10 !

So how can I make it work with Ubuntu 10.04 ?

edit: I have upgraded the kernel to version 3.2.0 and still no wireless!

What should be the normal temperature be for an Acer Aspire One 751h with a 9 cells battery running Kubuntu 10.10? The plasmoid indicates temperatures from 53º C up to 63º C (isn't this too high?)

I want to disable the touchpad while I type on my Aspire one netbook. If I issue the command syndaemon the synaptics driver is not detected:

Unable to find a synaptics device

So, I added the following to my xorg.conf file:

Section "InputDevice"
Identifier "Mouse0"
Driver "synaptics"
Option "Protocol" "auto"
Option "Device" "/dev/input/mouse0"
Option "ZAxisMapping" "4 5 6 7"
Option "CorePointer"
Option "HorizEdgeScroll" "1"
EndSection

It is still unable to find a synaptics device, however my touchpad works fine.

I listen to music almost any time I am on my computer. I often accidentally unplug my headphones. This has resulted in disturbing others around me. Does any one know of a way to mute the speakers (and potentiality pause VLC) when headphones are unplugged?

I would like to do this on my Laptop. It is an Acer Aspire One D150. The speakers are built-in to the computer. My headphones are standard 1/8 in which connect through the headphone jack.
