I've been using Cinnamon as my desktop environment for 7+ years.
But Cinnamon 6 has been a bit buggy, so I'm switching to Gnome in Fall 2024 (also to enjoy its vast extensions).
Then Gnome dropped X11 support in 2025-09 so I switched back to Cinnamon.
Applets, extensions are installed at ~/.local/share/cinnamon/.
User configs are at ~/.cinnamon/.
GDM issue
Cinnamon (X11) fails to load after update / Applications & Desktop Environments / Arch Linux Forums
Since 2026-04, GDM not working for X11 even with WaylandEnable=false in /etc/gdm/custom.conf
Only used GDM for GNOME session
sudo pacman -S lightdm lightdm-gtk-greeter lightdm-gtk-greeter-settings
sudo systemctl disable gdm
sudo systemctl enable lightdm # reboot or add `--now`Writing Extensions
