Helping my kid have a functional MIT AI2 learning setup based on Kubuntu (Ubuntu spinoff based on KDE desktop) Linux. This being a modern 64-bit system, I had to do some work to get the 32-bit emulator working. When I connect to the Emulator, the Emulator loads up fine, and then the Companion app also startup, and it says something like it is waiting to load the blocks, after which it turns into white screen with none of the components or the app show.
Based on this other older thread (Blank screen when emulator starts (LINUX)), I ran adb logcat and see some errors which might indicate missing components, and/or an out-of-memory error. Wondering if anyone can help figure out what's going on and what I should do to get this emulator working as expected ? adb logcat output:
I/global ( 280): Default buffer size used in BufferedReader constructor. It would be better to be explicit if an 8k-char buffer is required.
