Onshape suddenly stopped working with Chrome

ian_bottomley909

Today when I fire up Onshape it reports that my Browser does not support WebGL - it all worked fine yesterday.
Chrome is latest version: Version 114.0.5735.133 (Official Build) (64-bit)
OS is Ubuntu 22.04
Onshape seems to run fien in Vivaldi
Acceleration is enabled in Chrome
Little spinning cube shows ok on Webgl test page
Onshape Compatability checked says WebGL is not available.

Any help or toher checks I could make would be greatly appreciated

Hi Neil, thanks for the prompt respnse - unfortunately - already tried both of those 
I've noticed that the system also works OK with chromium (though complains about performance)

I've detrmined that Chromium is using the 'onbaord' intel graphics whereas Chrome is using the NVidia 1050ti - so I'm guessing that's where th root of the problem lies.

Go tthat info from here:

https://alteredqualia.com/tmp/webgl-maxparams-test/

Chromium says 

                         Unmasked Renderer: ANGLE (Intel, Mesa Intel(R) HD Graphics 630 (KBL GT2), OpenGL 4.6)
                           Unmasked Vendor: Google Inc. (Intel)

Whereas Chrome says

               Unmasked Renderer: ANGLE (NVIDIA, Vulkan 1.3.242 (NVIDIA NVIDIA GeForce GTX 1050 Ti (0x00001C8C)), NVIDIA)
                           Unmasked Vendor: Google Inc. (NVIDIA)

But I'm unsure as to how to get either browser to use the other GPU to try and pin the issue down.

Any thoughts?

cheers

Hi Neil, thanks for the prompt respnse - unfortunately - already tried both of those 
I've noticed that the system also works OK with chromium (though complains about performance)

Subsequently I've done ssome more resaearch and found a solution:

Key points seem to be

1. The system I am running is actually Xubuntu not Ubuntu (different window manager I believe)
2. I ran the NVIDIA Xserver settings app from the settings menu
3. Under PRIME Profiles - I changed the selection
from 
  NVIDIA On-Demand 
to
  NVIDIA (Performance Mode)

Now it works fine - not sure 'why' sadly ...

But hopefully that helps someone else

Many thanks

Ian, I have the same issue, Onshape in Chrome stopped working in Ubuntu. My Xserver settings don't appear to have a PRIME profiles option, any suggestions? Thanks.

Interestingly, Firefox on Ubuntu 22.04 works fine, I may just continue to use it, the performance is excellent.

Hi Howard

I've had this problem on and off for a while (not sure if it's a system instability - but things I have done that have changed the behavious in the past are:

1. The 'Prime profiles' thing mentioned above

(The internet says that this option is not displayed if you are not using the NVidia drivers - not sure if that applies here or not ...)

2. Enabling hardware acceleration in Chrome

    chrome://settings/system - turn option 2 on (quite how it turned itself off is another question)
   
3. Uninstalling broken NVIDIA drivers I had that i suspected were causing issues - only do this if you are confident (or like me, reckless)

      >> sudo apt-get remove --purge '^nvidia-.*'

Each of these has either fixed the issue ... or had the side effect of fixing it on separate occasions ...

Good luck!
