Thanks > for all your help! It is deserved after all the efforts :p. I sent patches for the issues you had (partitioning issue[1] and efivarfs[2] support). Now for the graphical issue, if you find a workaround, maybe using uvesafb as suggested by Florian, please let us know. Thanks, Mathieu [1]: https://issues.guix.gnu.org/issue/36783 [2]: https://lists.gnu.org/archive/html/guix-patches/2020-04/msg00707.html.
