Dear all, I've tried to run SMath (latest stable) on Ubuntu 22.10, but it crashed. The AppImage gives me some errors in the shell, whereas the Mono Version leaves me with a coredump-file. Below I post some information on my system. Please, can anyone provide me some advice on how to get smath up and runnning, sinc eI want to use it natively on linucx, avoid running it in a virtual windows machine!

Try to run with sudo.
Some mono programs, while nothing wrong with their code, don't run under debian based distros.
Actually they run without sudo, but you have to try a lot of times. When will it run, just pure coincidence.
There is no pattern to pinpoint the problem.
Regards

Thanks a lot @overlord!
Indeed, "sudo ./smathstudio_desktop_mono" did the job, but I'm wondering why? Is there any ressource I have to grant access for the user? Running smath as SU is a workaroung, but I would appreciate running it as normal user. Please, could you provide more information on "what" is the show-stopper here?
Kind Regards
George

All debian based distros suffer from this. And it is not unique for SMath also. A link to a thread for further examinationRegards

Ok, since I cannot figure out the problem with "broken mono package" or "permissions", I proceed with a workaround, that does the job - at least for me  First I create a Dockerfile that contains... Quote:# START FROM FEDORA 37
#
FROM fedora:37
RUN echo "root:something!" | chpasswd
RUN yum -y update
RUN yum -y install mono-devel util-linux
RUN mkdir /opt/smath
USER root
#
# EOF
and create an image using Quote:docker build -t smath:2023 .
On the host machine I installed the smath-mono package at '/opt/smath' and I start the docker container using Quote:docker container run -ti \
--rm \
-v /opt/smath/:/opt/smath \
-v $HOME/:/root \
-w /root \
--net=host \
--env="DISPLAY" \
--volume="$HOME/.Xauthority:/root/.Xauthority:rw" \
smath:2023
Starting smath inside the container using 'cd /opt/smath && ./smathstudio_desktop_mono' does the job  Hope that helps! Maybe there will be a "real" solution for the mono-package in the near future. Cheers, George PS: I'm just missing one thing... inside the container I have no access to my printers, thus I cannot generate a PDF, but I'm sure I will find a solution for this also!

Ok, printing issue resolved by installing also cups cups-filters and cups-pdf inside the container. This enables me to use the printers of the host system! However, I encounter some graphic problems, i.e. start writing to a new smath document, the page gets "blanked" out (completely white) after a few keystrokes. In addition, Sometimes the menus of the GUI are then transparent!? Any idea what is the reason for that? UPDATE: ok, I found, that the problem only occurs as soon as I type a whitespace, e.g. a string like "aaaaaaa bbbb". As soon as I type the first "b" following the whitespace, the text field is "blanked". In addition, if I left-click on the background, the whole page is "blanked". When I use "Undo" to reverse what I did, the "blanked" area and text field disappears, and the page is readable again. Edited by user 26 January 2023 18:36:13(UTC)
