VNC not working on HAOS hosts? #149

alexbelgium · 2023-05-30T19:16:58Z

Hi, I'm developing an HomeAssistant addon for your great app here : https://github.com/alexbelgium/hassio-addons/tree/master/free_games_claimer

I've ran into an issue : although it works great on amd64, I can't get the NoVNC webui to show on aarch64. The page just waits idly without any error message nor action until it timeouts.

Things I've tested (running your latest container straight from Portainer with all default settings on two different systems : amd64 virtual machine, and aarch64 rpi4) :

- Starting the addon : works on both systems (see collapsible log)

Xvfb display server created screen with resolution 1280x1280
VNC is running on port 5900 (no password!)
noVNC (VNC via browser) is running on http://localhost:6080
2023-05-30 19:14:18.276 started checking epic-games

Accessing webui from outside the container : works on amd64, waits idly on aarch64
Doing curl 127.0.0.1:6080 from within the container using a portainer console : works on amd64 (provides a normal response), waits forever on aarch64

Based on this behavior, it conluded the issue is limited to the aarch64 system and is due to the container and not the external docker environment - and therefore wanted to request your help. This does not affect the env variables system that works on both system.

Is there anything else I could do to make it work ?

Thanks !

Works fine for me on aarch64 via https://cloud.oracle.com:

What system are you trying to run it on?
You've seen the note in the README that Playwright requires a 64-bit userland (not just kernel)?

alexbelgium · 2023-05-31T09:18:10Z

Hi, thanks for checking that!

I'm using HAos which is a 64-bit os developed by HomeAssistant Home Assistant Operating System (HAOS) is using the Buildroot build system. Buildroot is not a Linux distribution in the classic sense. It provides the infrastructure and build system to build a Linux distribution.

Here is my log :

and it just waits forever... any ideas? thanks!

Performing other curl -v (such as google.com) works

vogler · 2023-05-31T11:00:38Z

It's strange that the image behaves differently depending on the host OS, but I don't see any other explanation.
First we should verify that noVNC is the problem:

Does connecting with another VNC client on port 5900 work?
Is the browser launched or does Playwright also have some problem? Check with ps aux | grep firefox while it waits for login.

alexbelgium · 2023-05-31T13:29:24Z

Hi, thanks

VNC doesn't work indeed (I've tested on my amd64 system it works)
here is the log :

ps aux | grep vnc
root         162  0.0  0.0   2884  1308 pts/1    S+   15:28   0:00 grep vnc
ps aux | grep firefox
root         164  0.0  0.0   2884  1316 pts/1    S+   15:29   0:00 grep firefox

Edit : I saw that error when starting vnc are suppressed in the script. I therefore execute sed -i 's|2>/dev/null 1>&2||g' /usr/local/bin/docker-entrypoint.sh before executing /usr/local/bin/docker-entrypoint.sh node prime-gaming and here is the full log below. I don't see errors within.

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster

  x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.

Have you tried the x11vnc '-ncache' VNC client-side pixel caching feature yet?

The scheme stores pixel data offscreen on the VNC viewer side for faster
retrieval.  It should work with any VNC viewer.  Try it by running:

    x11vnc -ncache 10 ...

One can also add -ncache_cr for smooth 'copyrect' window motion.

viny182 · 2023-05-31T14:28:04Z

Hello,

I'm with the same issue, but using HAOS 10.2 (latest) on the (amd64 / generic-x86-64) platform, which is indeed a working platform for @alexbelgium .

The only difference I have is that this is a physical machine, instead of a VM amd64.

Let me know if I could help to debug this in anyway...

Edit: direct VNC is not reachable on :5900 port, so noVNC is also not reachable trough browser on :6080 port.

viny182 · 2023-05-31T14:46:22Z

update: after insisting a lot to connect trough VNC direct client on port:5900 I was able to connect after pressing connect button several times on my VNC Client! However, it was already on one of the later stages, during the GOG login, so I have missed the login for Epic and Prime...

vogler · 2023-05-31T15:43:44Z

Removed the times in your logs and diffed (a: aarch64, b: amd64):

The framebuffer read rate is almost 15x faster on your amd64 (and there's strangely some more indentation).

Don't know if that is the issue, but it's the only difference I see.

Didn't find an issue for VNC or xvfb on https://github.com/home-assistant/operating-system.

What hardware is it? Would be helpful to compare the same hardware with different host OS in order to verify that the issue is HAOS (maybe some missing kernel module?).

viny182 · 2023-05-31T16:34:33Z

@vogler , I believe you are on the right track!

I have a amd64 machine, but it is indeed very old... It's a laptop with an AMD C-60 CPU with 2 cores @ 1ghz and 8gb Ram.

I notice that the add-on consumes 100% of CPU after start for up to 10 minutes, and then it decreases during time...

When CPU is high, I'm not able to connect to VNC, but the connection is not closed, it keeps "loading"...

I managed to connect to VNC 2 times, but it was only after the GOG started... In my case, I'm starting first the Epic node, then the Prime and lastly the GOG node.... Perhaps the CPU usage was low during GOG, but I have not checked.

However, when I managed to access it trough VNC, the performance was pretty well! Mouse and keyboard had good response, so maybe the start up process is what is creating the heavy load...

vogler · 2023-05-31T16:53:10Z

Every script starts Firefox and loads the respective website. Due to how the websites are built (lots of JS and images), I'm not surprised about high load on a 1GHz CPU. Still, I think it should be done in some minutes and then quit, such that it's fine to run e.g. every night.

I think the issue is just the slow frame buffer read rate which is already logged before any browser is started.
Crude approximation: 3B*1280*1280*30fps/1024/1024 = 140.625MB/s.
Not sure if it needs to read it that much but it's close to the reported 151MB/s.

viny182 · 2023-05-31T17:00:15Z

Yes, I agree the JS creates a high load on the CPU...

But is still strange taking that time...

For example, there is this other standalone firefox HA addon https://github.com/mincka/ha-addons/tree/main/firefox that is based on this docker image https://github.com/jlesage/docker-firefox with a similar approach with VNC.

In the same 1ghz cpu it opens in seconds, and I'm able to load the epicgames and login just like if I was in a native browser, from both VCN direct connection, and trough the browser... not sure if they use noVNC as proxy, I'm not that expert...

viny182 · 2023-05-31T17:02:19Z

this is the load for the Firefox addon I mentioned above ^

vogler · 2023-05-31T21:58:27Z

I checked this image out in #68, mainly due to its reduced size.
It's using TigerVNC (instead of x11vnc) and noVNC (with some custom styling):
https://github.com/jlesage/docker-baseimage-gui/blob/a246245ad6e7a76a0083fb2218faa15f8b5d870b/Dockerfile#L39-L49
However, Playwright has no support for Alpine Linux on which the image is based.

You can edit Dockerfile to install tigervnc-standalone-server instead of x11vnc and edit docker-entrypoint.sh to start it. However, I don't expect another VNC server to be much faster for an intranet connection.

It's hard to compare loads of manually visiting a page in an already running Firefox vs. a script starting a new Firefox and immediately automating actions in it.

alexbelgium · 2023-06-01T07:45:28Z

Update : actually VNC connects on aarch64 but only after several hours (around 6h). I've tried checking if arguments for Xvfb or x11vnc can help to improve read rate but without success for the moment.

I'll try your proposal with tigervnc - thanks

vogler · 2023-06-01T21:39:28Z

Is just VNC a problem or is the rest also slow?
VNC is not really needed for normal usage since you can login via the terminal.
You can use RECORD=1 to record a video of what the browser is doing.
Running DRYRUN=1 node epic-games takes ~8s for me on a MBA, via docker a few seconds longer.

vogler · 2023-07-13T09:08:42Z

Any update on this?

vogler · 2023-07-20T08:10:35Z

To clarify if the issue is with the image or the host, you could check if VNC is also slow using these images (both using noVNC):

https://github.com/fcwu/docker-ubuntu-vnc-desktop (Ubuntu, similar issue)
https://github.com/jlesage/docker-firefox (Alpine, not compatible with Playwright)

I can't connect to VNC using RealVNC and noVNC doesn't work either.
the browser loads endlessly when I try noVNC and VNC using RealVNC also loads endlessly until the Addon stops.

vogler · 2023-12-18T22:43:33Z

Yea, it's an issue with HAOS, not the used VNC client.

yoshimo · 2023-12-22T20:18:56Z

What can we do about it? HAOS does get regular updates so it should be possible to solve this.

vogler · 2023-12-23T10:54:28Z

@yoshimo

check VNC not working on HAOS hosts? #149 (comment)
open issue on HAOS

It's still open if the issue is Ubuntu or the VNC server in combination with HAOS.

We can't use Alpine as a base since Playwright doesn't support it.

We could try tigervnc instead of x11vnc.
