Hello world, this is Nick, thanks for joining me again. In this video, we're going to be setting
up Ubuntu and performing some basic configurations for the system. First off,
we need to install a VirtualBox component called Guest Additions, and this allows us
to run the the virtual machine more stable and with higher performance. So, as
in the previous videos, I'm going to full screen, and then once you've got
this in the menu bar on the bottom
you're going to select devices, and insert Guest Additions CD image. I've
already inserted that, which is right here. Now, as you can see the performance here
is quite horrible. So, I'm going to run this, click on properties, and gonna make sure
that its executable and it is. Now we do have to go into the terminal, or
command line, for a moment. So, this is gonna be your first look at the terminal,
we are going to cover quite a bit of the command line interface in Linux, in I
believe the second or third module of this series. It's quite big, and it can do quite a bit.
So, hit the super key, that's going to bring up the dash, you can also click this icon
on the top left to bring up the dash.
Here we have different scopes. So, the default home scope is gonna be a loaded
right now. I'm gonna switch to applications. In applications we're going to see
installed recently used plugins, so I'm going to select installed, and we can actually
look at the applications that are installed in the system, right now. This
is pretty inefficient if you're trying to launch an application, and know
exactly which application you want to load. So I'm gonna close the dash. Go to the
desktop. I'm gonna hit
the super key, bring up the dash, and start typing the application name that I want
to run, in this case it's gonna be terminal. You can see at this point once I get
term written in there, the first result is terminal, this is the one I want to launch. If
the application you're looking for is the first in the list, you can just hit
enter. It should launch that application. Now there are shortcuts also in Linux
to launch terminal, and one of them is to just click CTRL, ALT and "T" on your keyboard
at the same time and it gonna to bring up terminal here.
We need to do is open in the specific location, so within the file manager I'm
going to right click, and click open in terminal. Now here we can see this
location that we're in, we're in VBOXEDITIONS right here. So, what I'm going to
do is run this program, here.
Must be run with administrative privileges, which means you need to add sudo to the
beginning of this command.
The great thing about Linux is for anything to actually modify the core of the
system, install applications, remove them, you know stuff like that, it requires
administrator rights. It's gonna force you to enter your password. Now this can get
frustrating sometimes and so there are ways around this and we're gonna discuss that
in the very near future.
Run files or files with .RUN file extensions can be run directly from the
terminal by just basically typing the name of the file. Now, why I put a "."
and a "/" here is to indicate to the terminal that
the file that we want to run is in the current directory. So, "/" in
Linux means current directory, and that would be this, this is the directory
we're in. So, this tells it that file is in this directory, and the run extension
automatically runs it. So, we don't really need to you know issue a whole ton of commands,
it's pretty simple as far as running files. Now it's adding kernel modules, so the kernel has
we discovered in video 1 is called Linux, that is the kernel for Ubuntu,
Debian, Fedora, you know every Linux distribution out there,
uses Linux as the kernel. So, the kernel's job is to translate between software and
hardware, and so in this instance what we've got right now is the screen
resolution is pretty terrible. I think it's 1280 x 768, so it's very square, not
wide screen. So, what we're gonna do by installing these module, this is going
to allow us to configure the screen resolution to that, that the hardware
actually supports. So, that's why we need to install VirtualBox guest additions, in
order to get better performance. It's also very laggy right now and what we
should see is that once we reboot after installing these VirtualBox edition's
files, when we reboot we should see a huge increase performance, which is gonna be
great. This might take a little bit so I'm gonna pause the video, and I'll be back with this
successfully installs. Alright people so it is done. So, what we're going to do as
suggested on this line in the terminal right here, we may want to restart. So,
close this, this, and this is painfully laggy. It's not just a bit laggy, it's pretty
painful. So, in the user menu here, the cog icon, I'm going to go down to shut down,
and select restart.
