Official Unity 2020.2+ Unity Linux Distro Support

Thanks for the info!

People should know that Unity will work with any Linux distro derived from Ubuntu, in my case Linux Mint. Unity works fine with Linux Mint 20 Ulyana that is based on Ubuntu 20.4 already.

 

Can we get an updated dependencies list for 2020.2? I'm trying to install 2020.2 on Ubuntu 18.04 and getting this error:

Code (JavaScript):

1. Fatal error: required formats (xar, cpio, tar, gzip, xz) are not supported by system libarchive

But apt-get reports that my libarchive is the latest available.

 

I know that, I was just saying that Unity works fine on Ubuntu based Linux distros.

Regarding bug reports, there had been steps made towards people reporting problems that were not using Ubuntu 18 or 20 in the recent past; is that over and will we be considered not worthy of any help from you guys again?

 

I have the Unity Hub App Image in my Ubuntu 20.04 and all the unity editor seems to crash whenever I try to open ou create a project. Just the Unity 2018 works.

 

This means only the main GNOME version or the flavors as well?
What about xorg or wayland?


Thank you for your time.

And what about CentOS 8? Or users are still using 7 more than 8?

REALLY glad to read this!

What about Snap/Flatpak releases? Wouldn't that help? Or running dev things in contained environments just doesn't work?

2020.2 LTS will be out next year, right?

Thank you for your time.

 

Currently in all the 2020 betas on Ubuntu 18.04 the Editor performance is 6-9fps, always in single digits, in 2020.1.3f1 the default URP scene runs at 600fps on the same machine.

I'd submit a bug report but the bug reporter crashes... I'd submit a bug report that the bug reporter crashes.. but um...

Ubuntu 18.04.4
Intel i7-8700K
Nvidia GTX 1080
32 gigs of ram

Legacy, URP on both Vulkan and OpenGL

 

There is already a bug report. It's supposed to be fixed in b5.

 

The most important thing is to have a up-to-date list of the dependencies, maybe a official supported kernel version. Or better, have UnityHub list the dependencies of new installations.

Ubuntu is a great distro to have official support, if you also had vanilla Debian and Arch (or official Aur package) you would basically have 99% of the desktop linux users. But having Ubuntu and a Flatpack is more than good enough.

I'm using Artix Linux, kernel 5.8.12 Zen. Can confirm Unity 2019.4 and 2020.1 working almost flawlessly with Awesome WM 4.3, LXQT 0.15.1 (Qt base 5.15) and KDE Plasma 5.19.

Having the same low fps issue as jvetulani in Unity 2020.2.b5, haven't made a bug report cause i haven't had the time to see if it was my setup or a bug.

Thanks! Great work!

 

ye i would like if there is a list of all deps and stuff i need, atm on Void Linux i get glitching with UI elements all time

 

It's still in b7, 9 fps instead of 300-400 fps.

 

Yeah, it was announced that the fix would be for b8, unless...

 

hmm just installed Ubuntu 20.4 LTS , hmm UI gliching i got on void disappeared , i think tough its not void related cuz i first installed lubuntu and head same gliching, but i still get issue when i try to exit Unity it stucks/freezes and i have to kill it to close
tough maybe cuz am using 2019 lts unity version

 

b8 still has the 9-10fps bug... sad face. On a positive note, HDRP seems to be much more stable, and the new demo scene is gorgeous!

 

im trying to learn game develop but i have this problem i think compiler related
error mssage "error CS1056: Unexpected character" so any help would be appreciated. thanks

I currently bought a Pop OS laptop. so how does this work in linux? Just going to the Unity hub and do the same thing or do I have to click a different link?

 

I just switched to Ubuntu 20.10 and tried Unity 2019.4.16f1 and it was horrible on Vulkan. Opengl made a little difference but still, scene and game views were supposedly running at 200fps but the spikes were huge, making it unusable. Also resizing and moving windows in editor was just slow compared to Windows.
specs: Ryzen 5 1600, N GTX 1650, 16gb ram.

Hopefully one day i will be able to use Linux editor for my work projects too. But it's not quite there yet. Hopefully we can get there soon.

Edit: I found what my issue was, my mouse polling rate was too high, causing stutter when having pressed any mouse button

 

I don’t think mouse polling should have an effect on rendering stuff.
I had the same issues wih vulkan and editor performance.

I tried to run the windows version of the editor with Proton/DXVK in dx11 mode and it was far superior and much more responsive just like on windows.
It had some bugs but worked pretty good compared to how it was a few years ago.
Hopefully in a few years... (i really need dx11/12)

 

question: How did you install unity? just normally in Unity hub like in any windows machine?

 

Well, It's a bit buggy but essentially yes.
I used crossover, created a new win10x64 bottle, and installed the hub.
Then I installed the editor and created a new project.
The hub very messy, it can create projects but cannot open them.
To open a project I just used the wine task manager, browsed to the project folder, and opened a scene file as run.
I enabled high-performance graphics and DXVK in the bottle and installed DXVK and DX redists.

To be fair It's nowhere near usable xd
The compilers won't work under wine and if you add a C# script you get unclearable errors in the console about page faults.

I'm not sure if it will be officially supported ever but I have high hopes for full windows compatibility on Linux in a few years (Kernel 5.11 can emulate syscalls!!!)

 

Why use Wine or Proton when a native Linux version of Unity (and Hub) is available and working?

 

Because I depend on DX11 for my current projects.
It's not a viable use-case, I was just curious if it would work.

 

This bug is still present after 2 years.
Repaint after alt tab and top menu issue.
Happens if there is no compositing application running.

It's okay if it wont get fixed, just let me know please, thanks.

 

Happens on all versions other than 2018 one if a compositor is not running.

I switched to kde, with kwin compositor unity works fine.

 

For me, even in KDE, the bug still happens. Unity only draws the panels on mouseover.

 

I have Unity Hub installed, via AppImage, on Ubuntu Studio 21.04. I also keep in on an Ubuntu 20.04 machine just in case. So far, it works nearly the same on either, even though 21.04 is not an LTS.

In neither installation am I able to get a WebGL build to actually build. I have installed libtinfo5 and Python2. Both times, the build got further along, but ultimately failed.

I am lost as to what to try next.

 

What about Unity 2021 and Linux?

 

I've been trying to work with Unity 2020.3 on Linux Debian since the end of May, and every time I try and run one of the tutorials from the website, the thing crashes back to the Desktop.

Would there be a way to get a more supported version of Linux on my box? I know Linux support in general on Chrome is "experimental" at the moment.

 

No, I've been advised it could kill my system so not to do it.

Before you go insulting my Brother (do so and I'll report you) he's an Internet security expert who's done Uni and everything.

 

Hey, I stumbled upon this forum while searching for a potential solution. I've been trying to run the unity linux editor in docker using https://game.ci/ images, it seems that the support for GLSL reported by the editor is v3.3 and as such this means Gaia Pro will not work as it relies on compute shaders (I've made a ticket with procedural worlds about this as well). Is the problems perhaps Docker, or is there no official support for compute shaders in the linux editor yet?

 

I can confirm that compute shaders work on Linux. I'm using them.

 

Just to clarify, this is then used in the editor as Editor specific functions ran with Editor scripts? And not in a build/standalone?

If so, did you have to install OpenGL or anything special to set this up?

 

Yes, it's in the editor. No, I didn't have to install or configure anything to make it work.
I'm not using OpenGL though I'm using Vulkan, maybe that's why.

 

I see, then I worry that maybe it's just the fact it runs in docker which causes issues.

 

Maybe you can have a look at Case 1356898 to improve the LTS releases.
Other then this bug everything just works.
It feels like Unity reacts faster on Ubuntu.
Thank you for your work on this.

 

having a little problem with installing, since my / partition is not that big, would It be possible to offsite the
process of installation particularly the unpacking in the /home partition instead or atleast have a choice beforehand.
I'm on linux mint btw, not that it matters for this particular problem.

 

What are the installation steps? Is there some documentation somewhere? My experience getting Unity running on Linux has been ABSOLUTELY ABYSMAL. Running Hub from AppImage, downloaded the editor (I've tried both the current and LTS versions) and to that point, things are okay. But once you try opening the C# project, things take a very sharp turn towards ridiculous.

VS Code opens up fine, but OmniSharp dies (depending on how you installed the components ... flatpak vs apt ... it dies with different messages). It just seems to be a cluster of disagreeable versions. Whether it doesn't like .Net SDK 3 or it doesn't like .Net SDK 5 (I've tried both ... neither worked). Whether OmniSharp doesn't like the installed version of Mono and chooses to use its own (I've tried both ... neither worked).

I don't see how this is considered "supported" if you can't run the debugger and intellisense doesn't work because both rely on OmniSharp (not a Unity product) which doesn't like the version of Mono which doesn't like the version of .Net SDK.

Is there an install guide that gets you out of version conflict hell?

Here's the most recent error I'm dealing with below? Any takers? Thanks!

So my "solution" to this was essentially to abandon vs code. The dependency between Unity's own debugger plugin and Microsoft's C# plugin just isn't worth the headache.

Running Unity Editor 2021.1.20f1 with the JetBrains Rider package from snapcraft.io just worked out of the box. I had to install a .Net SDK (but didn't specifically have to install mono ... at least so far). I know Rider is a fee-based product, but for the headache it save it ... I'll pay the price of admission.

Debugger works (which was the biggest problem setting up).

I don't know if I will eventually have to install mono-devel, but so far things are working light years better than using the "standard" installation.

 

This is not Unity's fault. OmniSharp is crap.

Getting VS Code to work with C# is always a pain, not just on Linux but on Windows and Mac too. You always have to tweak things to get it to work, and then it updates itself (without asking you first) and it breaks again. That's why I gave up using it.

If you really want to get VS Code to work with Unity then first don't install it with flatpak, install it with deb or snap instead. Then if you search this forum you will find some guides on how to get IntelliSense to work. I wrote one here a long time ago. I can't guarantee its up to date.

Otherwise yes, Rider works out of the box. That's what I'm using now.

 

@MadWatch you are 100% correct. OmniSharp is trash, and I've shifted away from flatpaks to native packages.

At the end of the day, Rider was the clue that allowed me to understand what was needed. I was able to get it working using .Net 5 with full debugging in Rider. In this configuration, Mono does not appear to be needed.

So, with that I went back to VS Code with at least the understanding that .Net 5 SDK will work.

Then it just came down to the linkage between OmniSharp and the Unity Debugger extension. This definitely needs mono-devel to be installed, and you set OmniSharp to always use the global mono installation. I believe (but I'm not certain) what finally got me over the hump and got EVERYTHING working in VS Code was the choice of which "project file" you open when you're transitioned from the Unity Editor to VS Code. If you choose the solution file (.sln) ... you seem to be well and truly bork'd. But if you open the .csproj file, then the debugger works and I now have a full end-to-end pipeline.

It really shouldn't be this hard. Hey Unity ... enter into an agreement with JetBrains to include a free copy of Rider with every Unity installation. It'll make life easier for everyone!
