Hello Paul,
thanks for giving Sculpt a try, I'll focus on the most pressing issue as the system should not get stuck when closing a component.
Also, at the end of my session, when I closed Falkon, the full system seems to have hand... mouse cursor not moving anymore, F12 not reacting... Ctrl-Alt-Del not working but maybe it (Ctrl-Alt-Del) is not supposed to work in Sculpt.
- Is that behavior reproducible or did it happen only once?
In case you can reproduce it, one way to start investigating what part gets stuck would be to also start the 'nano3d' pkg in addition to the Falkon pkg (when using the preset 'nano3d' can be added via the '+' menu (Genodelabs → Demos → nano3d). If it keeps spinning but interaction is not possible anymore something with the input handling is wrong. Otherwise something related to updating the display might be unhappy.
Instead of 'nano3d' there is also the 'top_view' package (alex-ab → Top tool → top view). It it can show what component might generarte an unexpected load that could influence other parts of the system.
Last but not least you could also deploy the 'report_dump' package (Genodelabs → Tools → report dump) and point it to the file system on the USB stick. This will copy the information contained in the system reports the stick every minute. So when the system gets stuck, let it sit for a while and maybe we will a report log that shows what is going on. (You might have to expand the file system on the USB stick first as it is limited initially.)
- How did you close Falkon, via the runtime graph or perhaps by using the “Close” button in the title bar?
