Just had to run some commands from the console and ran into the Danish keyboard mapping issue - fortunately I anticipated this and had a cheat sheet with the Danish layout.
I’ve remapped the keyboard in the past on another system, following these instructions:
I recall that the options listed in the instructions were a bit different than what actually popped up on screen, but I got through it without much difficulty back then.
This time I went through the options (too many), get through what I believe is the last question (use ctrl-alt-bs to terminate the X server?), hit enter, and get this error message:
warning: start and stop actions are no longer supported; failing back to defaults.
I had just upgraded to the latest Polyscope, V5.21.2.
What’s changed?
