The plot thickens (pun intended). I attempted to get graphics via Mathematica. I tried
Graphics[Disk[]] and got
Failure Query timed out. Click to retry. {{ Failure list that I cannot copy}
However, ListPlot[{{1,1},{2,2},{3,3},{4,4}}] worked
and ListPlot[Prime[Range[25]]] also worked.
Circle[ {1,1},4] gave listing outputs that did not make sense So it is a problem.
Graphics[Polygon[{{1, 0}, {0, Sqrt[3]}, {-1, 0}}]] gave message Failure Query timed out . This is the case for all Graphics commands. PS - Exactly this graphics question appears in support.wolfram/kb/12490 but the answer is not applicable to Raspberry Pi.
