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 :-)

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...

Windows Subsystem for Linux with a virtual Ubuntu - no graphical environment, shell only afaik :)

No, this one works:


5.0-201810071412  Mon Oct  8 09:30:27 UTC 2018 gcc 4.8 [Production Spur 64-bit VM]
CoInterpreter VMMaker.oscog-eem.2437 uuid: 0e97c106-dd0b-437b-b1aa-e15257288c3f Oct  8 2018

VM: 201810071412 https://github.com/OpenSmalltalk/opensmalltalk-vm.git
...


(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.

curious, which graphic environment? Xming or something?

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.
