Hi,
in GRASS 7, the d.erase command is not supported in the main GUI.
For `d.mon wx0` d.erase removes all rasters and shows the backgroud.
d.erase bgcolor is ignored.
For `d.mon png` d.erase uses bgcolor as expected.
For the main GUI, the question is if the Layers in Layer Manager should be
rem
Vasek,
the main reason we have d.erase in the assignments and in the book is for
zooming to computational region,
including changing the resolution
# for d.erase: Zoom to computational region and switch off previous map layers
the manual page does not say it, probably because it was implied.
