maintainer of zuluCrypt here and i noticed this bug report from google search.
zuluCrypt as packaged by debian and ubuntu tries to root elevate GUI components and wayland does not like this very much and it causes the problem you reported. version 5.2.0 of zuluCrypt no longer supports running GUI components privileged to support wayland and this means this version is also broken even if you were using X11. I have binary package for various distributions here[1] but ubuntu 17.10 is not there yet so you are out of luck. My recommendations are: 0. Uninstall these zuluCrypt packages. 1. Wait for zuluCrypt to be properly packaged in ubuntu. The maintainer is aware of the issue. 2. Build preferably git version of zuluCrypt from source code since it has full support for wayland.
