Hi,
to investigate the problem you might open a bug at bugs.openmamba.org attaching your /var/log/Xorg.0.conf file and the output of ls /etc/alternatives.
/var/log/Xorg.0.conf
ls /etc/alternatives

Silvan
Sorry, I don’t have experience on this tool but if you have a test case in linux I might be able to investigate.
You may also post a request/bug to the developers of the project at https://www.uitwisselplatform.nl/projects/libewf/.
