ubuntu-netbook interview questions
Top ubuntu-netbook frequently asked interview questions
My touchpad is recognised as a mouse, and for this reason I cannot disable it while I'm typing nor can I take advantage of scrolling and multi-touch features that my touchpad should support.
My machine is a netbook HP Mini 210 1000SA and I'm currently using Natty 32bit, but I have experienced this same issue before with Lucid and Maverick.
I've searched the entire web looking after a solution for this, but I haven't found anything but lots of people experiencing the same problem, including users of different machines.
I really hope that there is a solution for this issue or at least that it will be fixed in Natty, as it is really annoying.
Is anyone able to provide us (me and the hundreds of poor souls with the same problem) a relief?
Thank you very much indeed!
P.S.: Information that might help:

Most recent Ubuntu 12.04 seems to be quite nice and Unity (3D/2D) works fine for me, however not on my old Acer Aspire One any more.
There was a times, when I switched from Windows XP to Ubuntu and was happy about system looks, effects and speed... now I attend to think that XP was really great comparing with 12.04.
I have found similar questions here but no reasonable answer: how to lower CPU usage for Unity (3D/2D) and memory consumption for Ubuntu 12.04.
With new interface I could not find how to disable background services...
It's Linux, it's should be the way to optimize without buying new PC... Please share your recipe!

I have an installed application, but I don't know its name. (By "name" I mean what I would type in a command line.)
Is there any way to see this? It seems so obvious, but I can't figure it out.

I want to "try" ubuntu-netbook off the livecd on my Dell Mini1010 (Poulsbo Intel GMA 500 graphics card). It tells me that there is:
"No required driver detected for unity.
You will need to choose the Ubuntu Desktop session once you select your user name.
If you are on Ubuntu live CD, the username is "ubuntu" and you have to enter a blank password."
I intend to install UNE Maverick on my Mini 1010 but I want Unity to function properly. Does this directly reflect what will occur if I install it? Is there a way to correct this issue? (what drivers do i need?)

When selecting a file in Nautilus, I would like to see the context options of the file (mouse right click) using the keyboard and not the mouse.
Example, when i iterate over the list of files in a folder with the arrows, and one of the files is an archive, I would like to extract the file here without the need to go to the mouse.
It is MUCH healthier to work with the keyboard.
Thanks.

I will be going to University soon and am looking for a tablet/netbook on which I can use a stylus to write notes (Chinese characters mostly). I have only found 2 netbooks (with swivel screens and full keyboards) that might work for me. One is the ASUS Eee PC T101MT, and the other is a Gigabyte Touchnote.
Does anyone know of tablets (keyboardless) that Ubuntu fully works on?

Running Xubuntu 12.04 on a netbook (Lenovo S10), the lightdm process which runs in the background takes up constantly a precious 12% of the CPU. Besides, this consumes a considerable amount of energy, and the battery life already isn't that good.
The process I am referring to is shown in htop as this command:
/usr/bin/X :0 -auth /var/run/lightdm/root/:0 -nolisten tcp vt7 -novtswitch -background none
Why is this process necessary? Is there a way to reduce its processor usage?

What has me slightly confused from all the different reports about Unity becoming the default shell in the 11.04 desktop edition:
Some claim and this is how most people seem to see it, that what currently is the UNE interface will be taken 1:1 (including any changes made during the Natty cycle) and used as the interface for the desktop version - meaning that the interface will be exactly the same for 11.04 UNE and UDE.
Some other reports talk more along the lines a "desktop unity", making it sound, that while both will be using Unity, the Desktop edition will get it's own Unity, tailored specifically towards the Desktop formfactor. So both editions will be using Unity, but with slight differences in the layout or interface.
So my question is, will there be any difference between 11.04 Unity "Desktop" and Unity "Netbook" interface?

I am stumped. I upgraded from 10.04 to 10.10 Beta 3 and for some reason I can't get Alt-F2 to do anything. Is this a known bug or am I just not doing the right thing?

I only have a 512 MB flash drive and was wondering if there's an ISO for Ubuntu that will fit on it. I really need to format my netbook.

If a laptop is powered on and connected to AC power, is there a way to issue a command that tells it not to charge the battery?
EDITED:
Perhaps charging of the battery may be stopped if there were a way to fool the system into thinking the battery is already at 100% charge.

I've just upgraded my Ubuntu Desktop from 10.04 to 10.10 on my netbook.
How can I install Ubuntu Unity for my notebook ?

After a long time of enjoying the bliss of ignorance I've been reading up a bit on the developments in the land of desktop environments.
One thing I didn't find was whether there will still be (a need for) a separate netbook edition once Unity becomes the default environment on the Ubuntu desktop.
Surely someone here can tell me what I need to know?
