I can run one desktop background image spanned across both screens out of the box, with no extra software installed. The trick is to find an image that matches the resolution of both screens together. In my case, with 17" monitors both at 1280x1024, I need an image that is 2560x1024. Now go to Control Panel>Personalization>Desktop Background and select the ...

The answers so far are good, but I thought there must be an open source tool that does this. It turns out there is: Dual Monitor Tools This is a set of Free (open source) utilities. It can configure wallpaper for a dual-screen setup. It can mix both landscape and portrait-mode monitors. It also has several other tools, including a screenshot utility.

VBoxManage startvm $VM --type headless will start the specified virtual machine in the background. To shut it down, request the shut down from the guest.

Not out of the box, but Display Fusion works perfectly (free version is good enough) You can either set up different wallpapers on different screens or span one wallpaper over dual screen. Works great with my dual 1920 x 1080 setup.

Absolutely! You are looking for a headless installation (Virtualbox). The way to start the machine from the command line is something like: VBoxHeadless --startvm Debian --vrdp=off However you will need some way to connect. What I do is mapping ports between guest and host. With this configuration, your host 2222 port will be mapped to port 22 of your ...

I just wrote a quick Greasemonkey script that checks the computed style of the body element and changes it to black (you probably want to choose a different colour): (function () { if (window.getComputedStyle(document.body, null).getPropertyValue("background-color") == "rgb(255, 255, 255)") { console.log("Setting new background color..."); ...

No, it doesn't save power. http://googleblog.blogspot.com/2007/08/is-black-new-green.html You can save power by turning down the brightness of your screen, or (obviously) by turning it off when you're not using it.

That appears to be SysInternals' BGInfo. It's a stand-alone executable that you place in your StartUp directory. You can create a Windows scheduled task to refresh it at an interval you choose. BGInfo basically writes a new desktop bitmap image every time it is executed. You can pick and choose the data presented, its fonts, colors, etc.

Not that I know, but it can be fixed with an AutoHotkey script. For instance, this will use Win+n to go to the next desktop background: #n:: ; use the Windows+n hotkey WinActivate, ahk_class Progman ; activate the Desktop MouseGetPos, xpos, ypos ; get current mouse position Click 0,0 ; click in ...

Taskbar Shuffle is a small program that lets you move your taskbar items around on Windows XP and Vista. It's one of those install-and-forget applications; the only time I remember that I use it is when I try to use a computer that doesn't have it installed. ;)

UltraMon from Realtime Soft supports this. By default, you are limited to using the same background image on each monitor. With UltraMon, you can use a single image for the whole desktop, or different images for each monitor. In addition, you can also create gradient color backgrounds. Wallpaper using a different image on each monitor: ...

Execute the shell built-in: $ set +m This works by turning off "monitor mode" so the shell doesn't report terminating background jobs. Although running the command in a subshell like: $ (sleep 2&) ...will also disable the message, the only reason it works is because monitor mode is enabled by default only for interactive shells. That is, the ...

Your school's IT administrators are using either group policy or a third party program to restrict what you can do with your background. I'd say that's a smart policy for them to implement, considering what many high school students might choose to use as their background when they have access to the web or USB flash drives. (I'm assuming high school based ...

Autohotkey. I've never come across something it couldn't do, what's it struggling at? (Apart from autohotkey, an application launcher like Executor, Launchy, or the previously mentioned Enso.)

disown does not change the programs STDOUT/ERR. They will still go to wherever you redirected them (using > etc.). If you did not redirect them, they'll continue to go into the terminal you started the program from (until you close that terminal, in which case they'll be discarded). To illustrate, run this in a terminal: bash -c 'while true; do sleep 1; ...
