How to Keep the Compiz Cube Zoomed Out and in 3D
Don’t worry. This blog isn’t turning into a tech tips blog. I’ve just been dreaming about 3D desktops for years and then it all comes at once along with everything else that Ubuntu has to offer. A working copy of Compiz is installed from the distro CD. It is setup to provide a change desktop animation which will probably be enough for most people. Here it is with a few other things turned on.
Your basic “cube” showing all available desktops.
NASA TV in 3D. Could it be called “virtualised TV” ? That’s full frame video running there, not a thumbnail. It’s a live window.
At a watchable size.
I didn’t know it could do this until I had to resize a maximised window. Peek at what’s underneath
The 3D windows from another perspective.
Your classic desktop view with the 3D tastefully visible in the background. You can just see the menu that is open, visible on one of the other desktops on the right.
So no more “Living in a box…. I’ve been living in a cardboard box !” as that 80’s song goes.
3D movement is almost completely free as long as the middle mouse button is held down over the desktop. But it won’t stay in that position once the mouse button is released (grrrr!), and will snap back to whatever desk is nearest. This just seems such a shame as I can’t admire this work of beauty with it’s virtualised video and everything. So after looking into accessibility options I found a way of locking the middle mouse button down.
It’s a bit of a hack, but it does use a legitimate way of altering X server mouse behaviour. I wonder if there’s a way of doing this already built into Compiz ? If there is, no one would tell me. Google would not find it.
In Ubuntu … (Note: “\\” shows where I had to split the line. It should all be on one line.)
Make sure you have a backup of your X server config file.
sudo cp /etc/X11/xorg.conf \\ /etc/X11/xorg.conf.bak
Edit it …
sudo vim /etc/X11/xorg.conf
If you don’t like the command line you can use this …
gksudo gedit /etc/X11/xorg.conf
Find this section …
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
EndSection
Add this line …
Option "DragLockButtons" "3 2"
The section will now look like this …
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "DragLockButtons" "3 2"
EndSection
The first number after “DragLockButtons” is the button to be toggled. In this case button 3, the middle mouse button on my three button mouse. The second number is the mouse button to use to activate the toggle.
Save the xorg.conf file. Type “:”, then “wq”.
Logout of Ubuntu and then back in again. That will restart the x server without having to restart the entire system.
Now you can click the right mouse button over a clear area of desktop and the middle mouse button will lock allowing free rotation of the compiz cube. You can walk away and leave it in mid rotation. Hit the right mouse button again to let Compiz focus back to the active desktop.
There’s only one drawback here if you only have three mouse buttons. The defined lock button can no longer be used as a normal mouse button ! I just use the right click key on my keyboard.
Users with more than three buttons can set the lock toggle button to an unused mouse key and won’t have this problem. Just set the second number to whatever mouse button you want to use.

Addendum: If you do use a multi button mouse then make sure you use one number in the “lock” field (see above). Click that button and then the next button you press will lock. It’s a toggle lock, so the next time you click that button the lock will be cancelled.
Ubuntu – On The Shoulders of Giants
In the late 90’s I was struggling with my life. I was struggling with a “mono culture of the mind” on my computer… Microsoft Windows. It reflected my programmed brainwashed view of the world. Then a friend of mine mentioned Linux (thankyou Paul !). I installed it and immediately I could see what was coming. Now, ten years later, built on the shoulders of giants, here it is. The Ubuntu distribution is a work of genius !
The screengrab above shows the same idea I had at the beginning of the millennium. It seems that other’s were thinking similar thoughts. Not as some kind of attack on Windows. I think Windows has it’s place like any product. Just as a way to make the users experience as easy as possible and open up freedoms.
Now I have Ubuntu in my Windows boot menu. It is such a smooth system ! It almost makes me blush to compare with some of the systems that make users jump through so many hoops just to get something done. It’s sad. They seem lost in comparison.
The age of the “Uber Geek” is over, and yet it is many of those Geeks that have been working hard on the things “under the bonnet” in Ubuntu. So suddenly I can install applications at the click of a mouse … no compiling or fiddling around. Those video card effects on windows that I’ve been trying to get to work for years on Linux are suddenly there by default. I just had to update the Nvidia driver and enable because it’s a proprietary driver (not open source).
All this may seem like reporting the fall of the Berlin wall about 6 months later, or going on about the Moon landings, but I have some “complications” shall we say, going on in my life (I guess everyone has a few of those
. It’s just a happy moment to see Tux chase off those angry Macho Geeky monsters who can turn the computer experience into a hair pulling hassle. Technology is a double edged sword. It does not automatically bring good. It has to be in the right hands. Ubuntu is like a whole colony of penguins storming the silicon castle and tearing down the gates so the people can come flooding in

Spielberg and Lucas Get It Wrong This Time
I went to see the new Indiana Jones film (Spoiler warning).
Oh dear. Where was the film production that was supposed to be like the other films ? The print was muddy. The editing sloppy. The action sequences were just badly filmed.
What were they thinking ?
Where was the masterstroke of action sequence orchestration that we saw in the first Indiana film ? The scene where Indi takes control of the truck carrying the Ark is still a work of genius. A homage to every stunt technique created in Hollywood history. So well edited and crafted that it can be watched over and over, and I still gasp at the way it pulls me in to the action.
Where were the crisp perfectly framed stills that we saw in the bar fight in Indi One ? Freeze frame your DVD in that bar scene and almost every frame jumps out like some carefully drawn frame in a graphic novel.
Well, it’s humbling. Even the masters can fail.
“Even Master fail he can sometimes..” Yoda (Lucas are you listening ?)
Sometimes one has to fail to make something brilliant.
The audience in the theatre I saw the film in sauntered out very quietly at the end. In fact they did seem humbled. “So even these guys can get it wrong sometimes”. Is that what they were thinking ?
I heard a very telling comment…
“Indiana Jones doesn’t do UFO’s !”.
I think the Cold War setting was a mistake. complete with the nuclear explosion, it was too much ! I strongly believe the Cold War is still something very painful to a lot of people. It’s too much to examine so closely again the pain of “MAD” in what is an escapist film. It is much more comfortable looking at these things through the lens of World War Two or the 1930’s. Those periods of history have become accepted, legendary. We’re still sorting out the Cold War.
I saw a review that said that even this Indiana release is still a lot better than “the likes of National Treasure”. I strongly disagree ! National Treasure is a film that is very much like the original Indiana release. Snappy, audacious, “it has balls” as some 1930’s Hollywood magnate might say.
I hope Speilberg and Lucas learn from their mistake. Even Masters are still learning !
I’m still looking forward to the Star Wars TV series and the animated Star Wars feature. Spielberg and Lucas still have a lot of talent in there.

The Cancer Quacks
So this hybrid embryo research is still being pushed through because it “will give us a cure for Cancer” as I heard this Scientist say on the radio (BBC Radio 4).
How long, how many decades, are we going to listen to this mantra ? How long are we going to allow ourselves to be duped and led around by the nose by this excuse that will end in more suffering and deaths ? We’ve had decades of cruel animal experimentation. Decades of people dying from Cancer, Aids, and other diseases while the same governments tell us about the CURE (if you want to call it that) in their own advice. Have we all gone mad ?
Nutrition. We’ve all heard it. Do I need to drag out the recommendations to eat healthier to save your heart or your mental life ? That IS the “Cure” for Cancer and Aids. These are natural treatments based on Vitamins and Minerals. Most people use it just by eating well, but advanced cases of these serious diseases can be treated by careful regimes of what we normally get in food … allowing the body to repair it’self … after all it’s evolved to do that over millions of years if given the right building blocks.
Don’t listen to these “Scientists” (they are not) who say that this kind of talk is “dangerous”. They work for the Pharmaceutical companies who have a vested interest in KEEPING you sick. But you don’t have to get involved in that fight. Just look at the advice from your government to eat well. Or go to your local health food shop. Do some research. Drop the fear. Anything is possible.

The Future of Video Gaming ?
I was looking into the people behind “Racer” … a high end car racing simulation that is free and runs on Windows and Linux, and I discovered that as well as doing simulation for the automotive industry (with the sim connected to a MATLAB physics engines, for example), they do an entertainment system.
It got me thinking about things like Crysis and the Battlefield series. What if the same technology was applied to these video games ? Maybe the floor could be moving and motor controlled. The rig could tilt when you run up a hill, and go into a different mode when you enter a vehicle. The cost could possibly be high and one of these things would barely fit in a living room safely, but maybe they could revive the art of the Video Game arcade with people craning their necks to see what’s going on. Safety could be a problem if it’s a standing game, although I suppose harnesses and padding could be involved. My idea could do with some careful thinking through as I could swear there are ways of cleverly simulating the physics of what is going on in Crysis and Battlefield … afterall the Hexatech machine is geared (he he) towards racing.
Looking at their websites gives an idea of the astounding level of high end engineering going on. I wonder if it will ever catch on for more than racing ?
