* Display Manager

  GDM3 and Gnome 3 is stock on the Dell XPS 13 7390.  They are
  occasionally convenient but I don't want GDM to start by default.
  Console login is good.

  Disable GDM at boot, use console login

  For Gnome extensions, disable the stupid validate check that breaks
  stuff every time a new minor point release is published:

  =gsettings set org.gnome.shell "disable-extension-version-validation" true=

  Caps Lock, GTFO of my keyboard.  Very specifically run =xmodmap=

  [2019-12-27 Fri]

  Apparently the =setxkbmap= suite of tooling now conflicts with
  =xmodmap= in mysterious ways and it's a tire fire of mappings.
  Remapping keys should be easy but having at least two different ways
  to remap keys makes it difficult at best.

** Zoom Screen Sharing

   This was a big pain in the ass.  Zoom sucks.  WebRTC was easy.

   #+BEGIN_SRC sh
     wf-recorder --muxer=v4l2 --codec=rawvideo --pixel-format=yuv420p --file=/dev/video0
   #+END_SRC

   Working on second monitor support:

   #+BEGIN_SRC sh
     wf-recorder --muxer=v4l2 --codec=rawvideo --pixel-format=yuv420p --file=/dev/video0 --geometry '1920,0 3840x1600' --device DP-2
   #+END_SRC

   This cuts off the right and left sides of my ultra-wide monitor.
   Maybe I'm doing it wrong, need to look at
   https://github.com/ammen99/wf-recorder/search?q=geometry&type=issues.

   Then tell Zoom to share the second "camera" which is just the
   virtual video loopback. I can't get any other pixel format to work
   so I'm stuck w/ =420p= but it's better than nothing.

** Rootless Containers

   #+BEGIN_SRC sh
     cat /proc/cmdline
     BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=848e68bc-2cf3-4532-a7ea-32fb8fa99c2d rw loglevel=3 quiet
   #+END_SRC

   Need to add =systemd.unified_cgroup_hierarchy=1= to enable mounting
   of =/sys/fs/cgroup= w/ v2.  I am running GRUB right now.

*** =k3s=

    Apparently this is screwing with =k3s=.  It fails with something
    about not being able to find memory cgroup.

    So maybe I need to add =cgroup_memory=1 cgroup_enable=memory= to
    the boot params?  I was using the AUR =k3s-bin= install w/ its
    systemd service and it was mad about this but it was running as
    =root=, too, which I really don't want to do.  I'm gonna try the
    regular install described in the Rancher docs and see what I get.

    https://rancher.com/docs/k3s/latest/en/advanced/#running-k3s-with-rootlesskit-experimental

    #+BEGIN_QUOTE
    Cgroups are not supported.
    #+END_QUOTE

    ☹

    Well, let's see WTF that manifests as:

    #+BEGIN_SRC sh
      curl -sfL https://get.k3s.io | sh -s - --write-kubeconfig-mode 644
    #+END_SRC

    Closer but now the networking is netfailing.

    [2020-09-21 Mon]

    I had to ditch =podman= and the dream of rootless containers to
    run k8s locally.  There are a bunch of in-work issues across
    =k3s=, =kind=, etc. about supporting rootless and cgroup v2 but
    it's just not working right now and this isn't my fight today.

    Looks like it's working w/ Docker...
