Video killed the Radio Star

Thursday, July 31st, 2008

We didn’t think watching videos was going to be a major use-case for the webbook, partly because it doesn’t have a DVD drive, and partly because we thought we were going to ship it with a 2GB solid state drive so not much room for big video files. As it turned out we have a very roomy 80GB hard disk and plenty of people watch video podcasts in MP4 format. As I mentioned before, the drivers for the graphics card don’t really show off it’s full potential and playing videos highlights one area that the teacher would put on the report as “could do better”

Fortunately for us, the webbook can indeed do better, with just a little guidance. This version of the OpenChrome driver doesn’t do a particularly good job of handling the X Video extension. The point of the X Video extension is to allow the main CPU to hand over all the complicated video decoding to the graphics card. Basically the CPU says to the graphics card, “Please do some video decoding, you can draw it in this rectangle here, the data is over there, get on with it whilst I go do some other stuff”. Well that is great in theory, but in practice the graphics card just isn’t pulling it’s weight at the moment. Luckily for us the CPU of the webbook is nippy enough to do all the decoding itself (although it would probably struggle on HD content). We just have to tell the media player not to attempt to hand off the drawing to the lazy graphics card. Press alt+F2 to bring up the run program dialog then type in

gstreamer-properties

This will bring up a settings tool as shown below. On the video tab change the plugin from automatic to X Window System (No Xv). Now try playing your video again and you should have it playing back in glorious technicolour.

There will be better graphics drivers for the webbook, probably in an automatic update at some stage.

The Web Without Wires

Wednesday, July 30th, 2008

Your webbook comes with a wireless card built in, it does 802.11b and 802.11g. I don’t think it does 802.11n but I am prepared to be proved wrong on that one.
The wireless radio circuit can be turned on and off by pressing Fn+F1. By default it is switched off. There is a bit of an issue on the early models, the wifi light on the front of the webbook does not get turned on when the wireless is activated, making it a bit tricky to tell whether wireless is on or off. Don’t worry, there is a fix for this.

press alt+F2 to get the run program dialog and type in

gksudo gedit /etc/modprobe.d/options


gksudo means “I want to be superuser when I do this”
gedit is the name of the text editor (lke notepad.exe but lots better)
/etc/modprobe.d/options is a file where we can pass options to hardware drivers as they are loaded.

Because you asked to edit the file in the text editor as the superuser you will have to put your password in first.

Add a line at the end and type the following

options ipw2200 led=1


this tells the wireless driver that it is also responsible for turning on and off the LED on the front of the webbook. Normally this should flicker every few seconds when active, it will be on constantly when associated with a hotspot.

Later models will have this set by default, unfortunately the first batch escaped without it.

When you have wireless turned on you can click the little computer symbol at the top right of the screen to see a list of hotspots within range. Click on one to join it, you may need to enter a WEP or WPA key.

oops I forgot my password!

Tuesday, July 29th, 2008

Any IT helpdesk worker will tell you that the most common issue they deal with on a Monday morning is users who have forgotten their passwords over the weekend. So what do you do when you forget your password and can’t log on to your webbook? (or for that matter another user of your webbook forgets their password) Don’t worry, all is not lost, and this is a great time to introduce you to the recovery console.

When your webbook switches on you will see the webbook logo for a second or two as the BIOS gets ready to start up the system. Just after this, hit the escape key and you should end up at a menu like this:

Don’t worry if you miss it, just switch off and try again.

Go down to the second option in the list, this should end with (recovery mode) and press return.

You will then be treated to lots of weird and wonderful messages flying past as you see it boot up. Those messages are normally hidden by the Ubuntu startup screen.

Eventually you end up at this blue screen (not a blue screen of death, but a blue screen of salvation!)

Select the option to “Drop to a root shell prompt”

At the bottom of the screen you should see a little # prompt and a flashing cursor. You are now at a command line with superuser powers. Try typing

ls /home

this should give you a list of people with home directories. Lets say one of them is “alan”. To change the password for this user type

passwd alan

and provide a new password.

Once you are happy that you have a username and password that you can use type

exit

to continue starting up the webbook, you can then log in with your new password.

Other commands you might want to use at the recovery console include

deluser –remove-home alan

this deletes the user called alan, plus the home directory and all contents. Use with caution!

oem-config-prepare

Once you have deleted all the users you can run this command to reset the webbook to the first user wizard. This means that the next time it is turned on it will ask for a username and location etc. You might want to do this if you are giving your webbook to someone else.

It is good to share

Thursday, July 24th, 2008

So you have your webbook set up and you can log on to it. But what about the rest of the family? Can they use it too? Of course they can, but we don’t want them logging on with your username and password, we don’t want them messing up your stuff!

From the menu at the top of the screen go to System-Administration-Users and Groups

and up pops the dialog below:

Note how most of the buttons are grey and inactive. This is because adding users is something that requires administrator privileges (also called root privileges). As you are the first user you do have these powers, but you have to press the “Unlock” button at the bottom to give yourself the extra privileges.

Whenever you see this screen you should remember the words of the great philosopher, Peter Parker’s Uncle Ben: “With great power comes great responsibility

After you put in your password all the buttons will activate and you can press the “Add User” button and fill in the form below:

now a new problem becomes apparent, you can’t see the bottom of the form! This is because the form was designed for a screen measuring 1024×768 pixels, but your webbook has a screensize of 1024×600. Those last 168 pixels do make a bit of a difference sometimes. Your first instinct might be to grab the title bar with the mouse and pull it upwards, that helps a bit, but you can’t push the top of the window beyond the top of the screen that way, so I will have to show you a new trick. Hold down the Alt key on the keyboard, then click and drag anywhere on the window you want to move and you will find that your mouse cursor turns to a fist as you pick up the window and move it. This will allow you to move the window so that the title bar is off screen at the top, and you can see the buttons at the bottom.

There are a few places where you might encounter overly tall windows, another notable one is when setting up a new email account with Evolution so this is a good trick to get the hang of.

As you set up users for your family and friends, if you set their profile as “Desktop user” then they won’t be able to do anything that would damage the webbook or mess with the settings of your other users.

Hello webbook, pleased to meet you

Thursday, July 24th, 2008

When meeting someone new it is polite to introduce yourself, lets meet your new friend, the webbook. Press the power button (the middle silver button near the hinge) and a few seconds later it will start up for the first time.
The webbook wants to talk to you in your language. It knows lots of languages, but I speak English so I am going to choose that.

Now it wants to know where you live. I live near London so I am going to use the map to click on London.

You may find the mouse a bit lively at this point, if you struggle to click on the city with the map leaping about you can click and drag the edges of the window to make it bigger or just select the city from the dropdown list, (which is arranged into continents) or you could try plugging in an external mouse to one of the USB ports.
Click the Forward button and it now wants to know a bit about the keyboard you are using. It will take a good guess at this based on the city you selected.


Now it is time to introduce yourself, and set up a password. Don’t forget this, and notice that it wants your real name and also a login name. It suggests your first name in lower case as the login name.


After a little while (it has some preparation work to do for you) it will present you with the login screen and you can put in your username and password to log on for the first time


And here it is, your webbook is ready. Have fun exploring the menus, we have put lots of nice things in there for you to find!

The Unboxing

Wednesday, July 23rd, 2008

Welcome to the blog of the team that brought you the webbook.

My name is Alan Bell and I will be showing you lots of tips on how to get the most from your webbook. Feel free to post questions on any webbook related subject (and feel free to provide responses to other people’s questions) and I will try to help as much as I can. Please bear in mind that this isn’t an official support channel, but I might just be able to get you an answer to your question direct from the mouth of the horse.

In the box

So having introduced myself, lets introduce the webbook.

The webbook is a mini laptop, or UMPC (Ultra Mobile Personal Computer) or SCC (Small Cheap Computer) or 4P computing solution (Power Performance Portability Price) depending on who you ask. For simplicity lets just call it webbook here.

It has a nice bright screen running at a decent resolution, 1024×600. The main processor is a VIA C7 running at 1.6Ghz, and it has 512MB of RAM. The hard drive is a very spacious 80GB drive, so whilst you won’t get the blisteringly quick boot time that a solid state drive gives you there will be plenty of room for all your stuff. Sometimes size does matter.

The graphics card is quite good, but right now the drivers for it are still maturing so some of the wizziest graphical effects can’t be used yet, it is however, perfectly functional. If you are a true geek you probably want to see the output of lspci and cat /proc/cpuinfo. If you are remotely normal you can skip the last sentence altogether.

In my mind the very best feature of this little laptop is the operating system. It doesn’t run Windows (well there were a few sold online with Windows XP, but I don’t know much about those ones) it runs Ubuntu Linux. If you are a long time Windows user some bits of the system will seem a little unfamiliar, but others things will be right where you expect them to be and in no time at all you will be wondering how you ever survived without it! Linux is very different from Windows in many ways. There are technical differences, user interface differences and even legal and philosophical differences. The overriding objective is to give you, the user, more Freedom to do whatever you want with the software, and I will talk more about that later. For now, plug in your battery and lets get started with the webbook.
