  • Anyone using it with multiple screens? I haven’t tried it out because it didn’t look like it would be great for that.

    I want something really lightweight where I can assign things to workspaces and then pull workspaces easily onto any one of my screens.

    XMonad was my favourite, but I’ve moved to Sway and I’ve got it set up pretty well now. Workspaces still have a home screen so it’s a bit more clunky to move them around between screens.


  • I’ve got multiple machines that do this, but all on nixos.

    After completing the below, entering systemctl hibernate errors saying hibernation is not set up for the system.

    This is weird, so I’d start here. Can you get the exact error and/or whatever it logs to journald?

    I’d ignore all the TPM stuff until you can hibernate it and resume with a password. Maybe the swap is just too small? Maybe something in /etc/systemd/sleep.conf?

    In case it helps, my device setup looks like this:

    NAME               FSTYPE      FSVER    LABEL                             UUID                                   FSAVAIL FSUSE% MOUNTPOINTS
    nvme0n1            crypto_LUKS 2                                          xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    └─encrypted        LVM2_member LVM2 001                                   xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
      ├─encrypted-swap swap        1        swap                              xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx                  [SWAP]
      └─encrypted-root btrfs                root                              xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx      xxxx    xxx /mnt/root
                                                                                                                                    /nix/store
                                                                                                                                    /
    nvme1n1
    ├─nvme1n1p1        vfat        FAT32                                      xxxxxxxxx                                xxxxx    xxx /boot
    [...]
    

    so luks -> lvm -> { swap, btrfs }

    Edit:

    https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate#Hibernation

    When the system is running on UEFI, systemd-sleep(8) will automatically pick a suitable swap space to hibernate into, and the information of the used swap space is stored in HibernateLocation EFI variable.

    So far I haven’t figured out from the systemd docs what “automatically pick a suitable swap space” actually means, or if that’s accurate.
