curious, which graphic environment? Xming or something?
Windows Subsystem for Linux with a virtual Ubuntu - no graphical environment, shell only afaik :)

I believe it has nothing to do with my command. Even if you try to just run
squeak -version in that environment, I think you'll get the same error.
No, this one works:

(Just wondering why the current Trunk image is delivered with a VM that has version 5.0 ...)
Creating the squeak.conf did not change the behavior for me.
I am using a Ubuntu WSL.

Uhmm... it's not a "problem" that needs to be fixed. The Rasbian distribution of Debian Linux is typically intended as single-user system on which you can safely assume that if the user does something dumb, then it serves him/her right when the system locks up.
In the general case of a multi-user system, you don't want someone to elevate their thread priorities and accidentally lock up the entire system. That's why you are not allowed to use real time scheduling priority in ordinary user applications.
Some Linux distributions enforce this by default, and others do not. I think that it more or less depends on the intended audience for the distribution.

Ah, obviously, it's CommandLine thread... So you use a regular windows VM when you want to switch to graphical I presume... I asked because i have tested launching xcfe in wsl directed to a windows X server (VcXserv). It works, but lacks of stability...

No, I'm not using a Windows VM.
On my laptop, Windows 10 is installed (but not Windows Server). I activated the feature WSL which emulates a virtual Linux, where I chose Ubuntu.
Afaik, WSL does not support graphical environment, and I did not even try to achieve this.
Hope this helps :-)
