Ubuntu's Unity desktop environment can run in Windows (wordpress.com) 170

An anonymous Slashdot reader writes: "This is one of the coolest tickets I've seen on GitHub," writes Ubuntu developer Adolfo Jayme Barrientos, adding "this kind of surreal compatibility between platforms is now enabled...the fact that you can execute and use Linux window managers there, without virtual machines, is simply mind-blowing."

"The Windows 10 Anniversary Update coming in August includes an unusual feature aimed at developers: an Ubuntu sub-system that lets you run Linux software using a command-line interface," explains Liliputing.com "Preview versions have been available since April, and while Microsoft and Canonical worked together to bring support for the Bash terminal to Windows 10, it didn't take long for some users to figure out that they could get some desktop Linux apps to run in Windows. Now it looks like you can even load Ubuntu's Unity desktop environment, making windows 10 look like Ubuntu.

    I used/supported Windows for close to 20 years before I retired in 2010. At that time I decided I was done with using MS products, and moved all of my home machines over to single-boot Ubuntu. After seeing what a "turd_in_the_punchbowl" Windows 10 is, privacy-wise, I couldn't be happier with my decision.. I suppose for those who are *forced* to use Windows, either by their job or perhaps they just *think* they *have* to use Windows, this might be useful, but not for those of us who don't care to be MS's "product" and use Linux natively...

    • Completely agree. I keep a virtual machine of each Windows OS just in case someone asks "how do you do this". Much easier to just load it up to see. Mind you, after 7 I loaded them up far less because they became less easier to navigate and seem to be forcing people in using a crappy product. 8 with its look that was great for a tablet, terrible for a laptop (until they brought back the start menu). 10 and this non sense of "get the app" can burn in hell. Long live Debian on all my systems since 2002.

          Yeah, pretty much. The NT kernel was designed from the start to support multiple subsystems (think OS/2, POSIX, Windows). Hence, there's an abstraction layer that lay dormant but came in handy for something like this.

          SFL builds upon something called "pico processes" - which is derived from the initial idea of multiple subsystems. A pico process is a process that is stripped for everything OS specific.

        This is incorrect. Wine is a userspace shim that operates at the library-call (API) layer, and translates Windows API calls like `CreateFile` to Linux equivalents.

        The subsystem for Linux on the other hand operates at the system call (ABI) layer, implementing Linux system calls in the Windows kernel.

    If small developers with limited time budgets can just target their game at Linux, and have it automagically run on Windows, this might be quite the attractive option. No porting, just write for one "lowest common denominator" and let the OSes themselves sort it out. I would assume things intended to be cross-platform, like Vulkan, would also fit into this "it just works, everywhere" paradigm.

    • Interesting thought... though unfortunately, when it comes to games, the biggest issue is that they are (usually) tied to Direct X, which is Microsoft Only.

      There are efforts to port Direct X to Linux (the WINE guys), its an uphill battle as it requires tonnes of reverse engineering and testing, plus MS likes to make massive changes in new versions.

      If game developers were to move away from Direct X, and on to something cross-platform, then the bar is much lower to supporting Linux and friends.

        If game developers were to move away from Direct X, and on to something cross-platform, then the bar is much lower to supporting Linux and friends.

        Speaking as a game developer... I'd suggest its not any technical hurdles that keep games away from Linux. Most game engines, whether commercial or custum, are written in portable C++, and use abstraction layers to hide any platform-specific code. In my own game engine, I'd estimate that platform-specific code only amounts to less than 5% of the total code.

        Rather, I think it's simply the market-share of Linux... or rather, the lack thereof. Many games have Mac ports, meaning they obviously have an OpenGL renderer and POSIX compliant backend, but still no Linux support. It's pretty hard to get motivated to support an entirely new platform that only has 1% market-share, and it doesn't help matters when that 1% is further fragmented into a bunch of different distros, further complicating support and compatibility testing.

        It's the same problem Windows phones have. By all accounts, Windows phones are pretty nice, but no one makes apps for them because of the abysmal market-share, which in turn drives more users away. It's sort of a catch-22 for platforms with a small market-share, making it extremely difficult to break in.

        • by Mal-2 ( 675116 )

          I understand about market share. Say Linux is 10%, OS X is 20%, and Windows is 70%, just for the sake of argument. Right now it seems to pay to develop for the 70%, then maybe port for the 20%. What I'm proposing is that the mechanism works the other way around. Target the 10% knowing that the other 90% will be able to just run it unchanged. It may not have the right "skin" for that platform, but I can't think of many games that do, and the "authorized look and feel" changes from time to time anyhow. This d

          • It depends on what you mean by "Linux". When you say Windows there are only a couple of actual versions that it would be, if you're talking about Linux it's just the kernel and there are many many different customized Linux-based operating systems and different drivers with varing performance under certain circumstances. For example you have SteamOS and Valve partnered with nVidia to include their proprietary drivers and Gameworks technology in Valve's Linux-based operating system, yes it's Linux but that d
        • If the Game Engines are already abstracting this away, why /not/ provide builds for smaller OS's. I know there are extensions to Visual Studio to build binaries for Linux.

          I think what a lot of game developers are missing is that gaming is the /only/ reason many users are keeping Windows. I'm 100% positive I know at least a dozen people personally (and I'm not a very social person) that would ditch Windows completely if they could game easier on Linux. Is that extra 1% effort not worth it to you to provide a

          • There are a few reasons. Many commercial games use a lot of middleware libraries, not just the game engine (just count the logos on some games' splash screen). I was working as a contractor for a port recently, and I think there was easily a dozen middleware components in the game. These types of libraries tend to be licensed on a per-platform basis. Even if they're available on Linux at all, the licensing costs alone might preclude any reasonable chance at profits. Moreover, it's never "free" to devel

            • Thank you for your further input.

              I guess the TL;DR version is "because bu$ine$$" which is what I always assumed in the first place. I'm guessing very few (if any) managers or higher-ups even know that anything exists beyond Windows and OS X (or "PC" and "Mac" as they usually put it). I can see the uphill battle if a dev team tried to push for it.

        This is exactly where Vulkan and perhaps OpenGL have to take up the slack. For all the things Notch did wrong coding Minecraft, he made a fundamentally sound decision to not be tied to any particular OS or hardware platform. So long as the cross-compatibility can be maintained while ditching the pitfalls of Java, that part of the model is something other developers should look to emulate, because it worked out very well. Minecraft "just runs" on pretty much anything with sufficient power to run it. Unfortun

These makers could also fund WINE and a Windows driver compatability layer for Linux, which would eventually payoff in freeing them from MS royalties.

      Here's the problem with that idea: it is not really possible. It's possible to emulate Linux because it's open.

      Then there was IE that sanely used (by default) "box-sizing:border-box;" - which conflicted with every other browser as "border-box" includes padding and borders.

      CSS does the width include the padding? (2009) [stackoverflow.com]

          border-box

          The width and height properties include the content, the padding and border, but not the margin. This is the box model used by Internet Explorer when the document is in Quirks mode. Note that padding and border will be inside of the box e.g. .box {width: 350px; border: 10px solid black;} leads to a box rendered in the browser of width: 350px. The content box can't be negative and is floored to 0, making it impossible to use border-box to make the element disappear.

          Here the dimension is calculated as, width = border + padding + width of the content, and height = border + padding + height of the content.
