[GRASS-dev] d.mon segfaulting on debian/ubuntu custom/docker

Hi,

running

d.mon start=cairo
d.mon stop=cairo

will lead to Segmentation fault.

same for

d.mon start=wx0
or

d.mon start=png

I'm using GRASS 7.8.2, official packages from Ubuntu 20.04, nothing fancy.

When tried docker image

docker run --rm -ti -v $(pwd):/data/ -v $(pwd)/grassdata:/grassdata
mundialis/grass-py3-pdal:stable-ubuntu

it was segfaulting too! so was debian

when trying -alpine , no problem (or did not seem to be)

Any hint, what could be the reason?

No idea, just a silly question…
Did you try rendering any maps?
With cairo I usually set the output variable…

I’m using “d.mon start=cairo out=/path/to/file” daily and I have no problem.

apt-get update
apt-get install grass

grass -c epsg:25832 grassdata/gb
