Blank Visualizer Window

[Pagnon David]

Hello,

The visualizer window is black on Opensim 4.1 and 4.0 on my personnal laptop.


- There is no error message or little red sign on the bottom left
- Restarting doesn't change anything.
- Reinstalling idem.
- It works fine with Opensim 3.3

My environment:
Win 10 Pro, 2004 (which I just force updated)
Lenovo model 4282A82, x64
i7-2720QM CPU @ 2.20GHz
RAM 16 Go
Graphic cards: Intel(R) HD Graphics 3000 + Nvidia Quadro 1000M

Now on the FAQ I see that the most common reason for the OpenSim GUI not being able to launch the visualizer is "No WebGL support: some older machines do not support Hardware Accelerated Graphics rendering used by the new OpenSim Visulization."

Does it seem like it is the problem? I can't get a straight answer whether or not my graphic card supports hardware acceleration. If not, there is just no workaround?

Thank you!

Hello,

Thanks for reporting.

If you don't see the error/red error bubble after the first launch (because of a cache that gets built), you can still look for a detailed log file under the folder C:\Users\${user}\AppData\Roaming\.opensim where logs are kept, one folder per version. Your Graphics card is likely powerful enough to support WebGL but there're many players involved (e.g. drivers, are dedicated graphics used or the Intel integrated one?) It's also possible that the issue is somewhere else due to the embedded browser crashing which is more inline with the black window (jxbrowser will appear in the crash call stack). Let us know what you find out and we'll try to help you. The comparison to 3.3 is rather moot since it's quite different technology, but feel free to use version 3.3 for the short term or course work if urgent.

Hope this helps,
-Ayman

Hi, and thank you for your support Ayman!

I'm clearly not good at any of this, so I'm providing as much information as possible.

Which file should I check for a log?

My drivers are up to date.
Under nvidia settings, my prefered GPU is Nvidia processor.

I don't have that switch allowing for hardware accelerated GPU scheduling (despite I upgraded to windows 2004), which may indicate that it's not possible on my computer.

It's also possible that the issue is somewhere else due to the embedded browser crashing which is more inline with the black window (jxbrowser will appear in the crash call stack).

I was wondering if it could be a jxbrowser issue, but to be honest I'm not sure how to make it sure or how to fix it. I checked this page but it doesn't seem appropriate, and I can't find the file jxbrowser-chromium.dmp they are talking about.

Thanks again for your help!

Thank you for sending, typically the log is in var\log\messages.log as a text file.

Best regards,

Sorry I didn't have access to my personal computer in the last few days, here is the log!

I know I shouldn't do it too often, but here is a little UP

[Ibraheem Al-Dhamari]

I had a similar problem when building from source. Usually, I had to install/update one or both of these tools: JxBrowser and threejs !

[Pagnon David]

Thanks for your answer, I didn't build it from source though.
But maybe it's worth the try. In that case, do you mean I should first build jxBrowser and threejs; and then build Opensim?

[Ibraheem Al-Dhamari]

Probably, I don't use the release version. In your case hat I would do is remove everything, restart, redownload then re-install. Also try different versions to isolate the problem.

Good luck!

[Pagnon David]

I already tried this, it happens for both 4.0 and 4.1, and is probably due to a problem in jxBrowser. No idea what this problem is, if I'm the only one facing it, not how to solve it though
