I'm using 2017.4.7f1 for project purposes. I'm trying to play video files in a built projector on Ubuntu 18.04 LTS. The [documentation](https://docs.unity3d.com/2017.4/Documentation/Manual/VideoSources-FileCompatibility.html) states that for imported VideoClips, they need to be transcoded so they will become (presumably) WebM. Ok - understood that MP4 doesn't work on Linux. All works fine, except when using the dwm window manager, and our projector just hangs after the splash screen. The projector works fine in Ubuntu's default window manager.... hmm.
Trying to find a workaround, I externalised all the video assets. I adapted VideoPlayer to use "URL" as the Source, and my code to set .url instead of .clip. I've tested it on Mac using .mp4 and it all functions perfectly.
So now to get it working on Linux. I re-encoded the videos to .webm and tweaked my code to load the appropriate .webm instead of .mp4
It doesn't play.
I'm starting to believe VideoPlayer has very poor support on Linux platform. Does anyone out there have actual real-world experience of successfully having a VideoPlayer load an external video file on a Linux build?

Linux build doesn't work properly
I created a project in Unity 2018.2.11f1 and added some spirtes and a GameObject for the player to move around and built it for both Windows and Linux. The Windows build works fine but when I test the Linux build and start the game from the launcher I get a window that is dark gray and then goes blue.
It looks like it's loading, but not rendering properly. I've tried a couple different projects with buttons and actions and they all work, but I can't see anything but the blue background.
Has anyone else come across this? There doesn't seem to be any errors in the [log file][1], it just doesn't load anything.
(For reference, I'm building from Windows 10 to Linux and running the standalone player in Debian 9 and have gotten other games that other people have made in older versions of Unity to run)

Hello,
we are using Unity 2018.1.9f1.
Our game builds and runs on Windows, but we have a problem with Linux build (on Ubuntu-18.04.1).

Linux build only displays colours
I need some help with building for Ubuntu in Unity. When I execute the file (it's set to executable), it only shows colors and plays the music. But the camera is completely empty and it also skips the standalone player setup box, which is shown in Windows. I tried building it for both 64 and 32 bit, with no success whatsoever. I appreciate any help you may provide.
Edit: I updated and tried again, now the window popped up, then everything froze.

Problem with Unity chat server build hanging on loading in CentOS 7
Hi all, can anyone help me discover why when I run a headless Linux build of a server for a dedicated Linux server on the Internet the program seems to hand when chatserverx86_64 executable is started up prefaced by ./ in my home directory ? Or maybe I'm supposed to run it somewhere else or in some other way. Anyway, my chat server *does* work, but I lose control of my console window after starting it up. Which is no way to do business, of course. Attached is the output of what what I see in my console window.![alt text][1]

Is it possible to place a 3D model in a web server?
My interest is highly detailed architectural models. I have seen many in YouTube and elsewhere, but they never explain two very important things:
- Are they interactive or just a prepackaged video?
- Is the user sitting next to a desktop PC with plenty of bandwidth?
Furthermore, my preferred development is Visual Studio but my preferred deployment platform is a Linux web server.
Can Unity achieve what I need?
TIA

Memory Leak on Linux
Hi,
I have been using Unity ml-agents on my Mac to create environments. I then build the environment for Linux and upload it to git in order to pull the environment down on a Linux machine. When I use the environment on the Linux machine, I run the learn.py algorithm, but it continues to use more and more memory until it runs out and it crashes.
I am running on Ubuntu 16.04 with ml-agents 0.4.0b and Unity 2017.2.0f1.
I know this was an issue with textures in the past, but the version of ml-agents that I have is after this issue was fixed.

Lightmapping through Command Line
Hello,
I was wondering whether anyone has some advice/scripts on doing light mapping over the command line.
To be more detailed, I have access to a linux cluster and would like to bake a procedural Lightmap there, as it will always crash on my MacBooks. So I already saw that it is possible to install Unity on that cluster and I can somehow move my project on there, but now I need to somehow open the correct scene and bake the Lightmap through the command line tool.
Would be great if someone could help me out.
Best regards,
Fred

Is using Unity a viable way to create cross-platform screensavers?
I am trying to figure out if it is viable to [create a screensaver][1] using Unity. I have already figured out how I would handle the command line arguments from Windows, but I am still not sure if I can use the preview window on Windows. To do that I would need to set the parent of the game's window. I also don't know how screensavers work on MacOS and Linux.
You can handle the Windows command line arguments by creating a C# script that is set as the screensaver. This program saves the arguments in a file--or the Windows Registry--which the Unity app can access. Once it does that, the program runs the Unity app. This seems like sort of a hacky way to do this, but this way you can handle all of the programming in Unity. If Unity detects that it is running on Windows, it can look for the arguments in the dedicated file, it can also do similar things if it detects it is running on MacOS and Linux.
I don't need to target mobile devices since turning the screen off saves battery than running a 3D environment with the screen always on.
So two questions would be:
1. Is it possible to set the game window as a child of another window using a [window handle][2]?
2. How do MacOS and Linux screensavers work, and how would you get Unity to run as one?

How to separate the engine and resource parts of Unity
Hello,
I'm working on an android app written in Java that will contain multiple Unity games.
I would like the player to be able to press a button to play the first game, then another button to play another game, and so on.
From what I understand so far, in android applications, the UnityPlayerActivity uses the libraries available in unity-classes.jar
unity-classes.jar then uses the native functions in libmain.so, libmono.so, and libunity.so to run the actual game
libunity.so contains assembly code that refers to the folder "assets/bin" where the actual code and assets of the game exist.
Now, in order to let the player play more than one game, I need to choose the files that need to be placed in "assets/bin" depending on which game the player wants to play; for the first game I put the files of the first game, for the second game I put the files of the second game, and so on.
The problem is that it is not possible to modify the files inside "assets/bin" because they are inside the apk, and an android application is not allowed to modify its own apk.
Is there any way to separate the Assets resources, such as the Assets resource in the SDCard directory, the engine's required startup file is placed in the APK, runtime, can specify the resource directory to be loaded to the engine, so that the game is running normally?
