* Environment I am currently running Guix on top of Fedora 26, which comes with Gnome 3.24.2
As recommended(1), I source *~/.guix-profile/etc/profile* in *~/.bash_profile* to make all the exported variables recognized by login shell. * Issue After installing python-ipython with guix, guix exported the following variables: GUIX_GTK3_PATH PKG_CONFIG_PATH The next time I login, Gnome was broken, displaying nothing but a black screen, except for Owncloud client(which is based on Qt). And all the key bindings are gone. So, I used tty to move the `source` command from *.bash_profile* to *.bashrc*. After that, Gnome came back and functions as usual. * Version $: guix --version guix (GNU Guix) d9a38cc255d853b2694a01b5704c1daedbb56742 [1]: https://lists.gnu.org/archive/html/help-guix/2017-05/msg00072.html
