Sorry I couldn't be of much help :)


§ TESTING PROCESS



#+begin_src shell
guix time-machine -C mate-channels.scm -- system vm mate-os.scm
#+end_src



❷ Run the resulting virtual machine:

#+begin_src shell
/gnu/store/qa5gc34qgmjhk12if284nkl2v1mz869f-run-vm.sh \
    -nic user,model=virtio-net-pci -m 2024M
#+end_src

Good luck :)

I tried the process below assuming it would get me the same MATE version you're getting trouble with. The resulting virtual machine displayed the MATE desktop normally. I can use the Applications, Places and System menus. If I were in your shoes, I'd roll back to the previous system generation. But if you'd like to investigate the source of the issue, maybe figure out were MATE logs errors to see if you can find any clues. Or try deleting stale state related to MATE. I don't know where MATE saves its state, though. ❶ Create a virtual machine using the MATE desktop service defined in the Guix revision Gottfried is using. (See «§ SCHEME FILES» section below for the contents of the mate-channels.scm and mate-os.scm files.) ❸ Wait for the GDM login screen and start a desktop session for the Tester user (password is: excuseme).
