Cannot run with Ubuntu 22.04

Hello

Has anyone managed to install and run Mbed Studio on Ubuntu 20.04.1 ?

When I try to run it, I get the following error: [3142:0908/091659.738773:FATAL:gpu_data_manager_impl_private.cc(439)] GPU process isn’t usable. Goodbye.
Trace/breakpoint trap (core dumped)

I’m running a 4th Gen i7, with a Quadro P620 GPU

Hi Nicholas,

can you please add some more details?

Does this happens during the installation when using the program? If the latter, does it happen when Mbed Studio starts or is it when doing some specific operation? Did you see any error when installing Mbed Studio?

Mbed Studio is built using Electron. Do you use any other Electron application on your machine (like Slack or vsCode)?

Thank you for the information,

Federico - Mbed Studio Team

Hi

I have VSCode installed, and it works fine.
The error is when I try to run mbed studio from a bash shell. I did not notice any errors while installing.
Strictly, I am using Mint which is derived from Ubuntu 22.04. Maybe there is an issue there?

Here is the transcript:

Hi Nicholas,

thanks for your answer.

Unfortunately we don’t officially support Linux Mint, so there is not much we can do about this issue.

In case you want to investigate this issue, in our code base we don’t make any direct use of the GPU features, so it might be possibly related to Electron, the technology we use to package Mbed Studio.

Good luck,
Federico - Mbed Studio team

Hi

I will try and Ubuntu 22.04 to see if that works (As Mint is just a derivative of Ubuntu, it should be possible to get working).

Nick

Hi Nick,

I hope this info helps.

I have Mbed Studio(1.4.4) running on Linux Mint 20.3. I also have vsCode(1.71.0) running which states it has Electron(19.0.12).

I’m using a 2015 HP Notebook (AMD A8, 16Gb RAM, SSD and built-in Radeon R4/R5 GPU).

It just worked for me so it might be worth trying to re-install and checking for any unresolved dependencies or error codes.

Let me know if I can check anything for you on my machine.

Kind regards

Mark

I am on Mint 21, which is based on Ubuntu 22.04. I’ve tried installing mbed studio, but no change.
Looks like I will have to switch to Ubuntu 22.04 for now. Thanks for the suggestion.

Hi

Ubuntu 22.04 the same.

I run mbed-studio --no-sandbox and it runs

Nick

Hi Nick,

thanks for testing Mbed Studio also with Ubuntu 22.04.

It looks like you have two different errors, one related to the GPU and another related to a missing Mbed Studio module. The latter might be caused by some issues with the Mbed Studio installation so my first suggestion would be to reinstall Studio to see if it helps.

Hi

I’ve tried re-installing on two machines (both using Ubuntu 22.04 LTS) and nether start.
I can get it to run (on both) if I type the following:

mbed-studio --no-sandbox

Hi Nick,

thank you for the investigation. The --no-sandbox option should generally not be necessary but it should not cause any harm. We’ll try to investigate why in some cases it might be necessary.

Thank you,

Ok thanks. Let me know if you want me to test anything else (always happy to help).
I will try and find how to modify the taskbar shortcut so my students don’t need to use the command line.

Nick
