# narrator: it was not

# what I did instead was go into about:config and enable firefox hardware
# acceleration, which may have fixed the problem
# layers.acceleration.disabled was set to on
# layers.acceleration.force-enabled was set to false
# I flipped both those values
# there's still some weird stuff going on here, but I"m going to put it down

# execute the base2term-spacedark shell script from my base2term repo and

# Stop cinnamon from opening up the calendar when I hit <Super>c
# at first, I thought this would be in gsettings, so I looked with:
gsettings list-recursively | grep Super

# and was disappointed when it wasn't there! It turns out that cinnamon applets
# live on their own in /usr/share/cinnamon/applets, and there we can find the
# offending shortcut:
#
# $ rg 'Super>c'
# notifications@cinnamon.org/settings-schema.json
# 35:        "default": "<Shift><Super>c",
# 
# calendar@cinnamon.org/settings-schema.json
# 41:        "default": "<Super>c",
#
# it says "default" - but I don't see any way to change it other than editing
# it in the source code? Surely there must be one?
#
# ah ha, it's under the applets system preferences panel! click the gear icon
# and assign another shortcut
#
# (if cinnamon doesn't store that in gsettings, where the hell does it store
# it? whatever, I got a life to live.)
#
# and wahoo, I have super+c and super+v as c+p in terminal
#
# also go to applets -> grouped window list -> hotkey for cycling through
# thumbnail menus and change to "unassigned"

# no login
# --------------
# https://wiki.archlinux.org/index.php/LXDM suggests editing /etc/lxdm/lxdm.conf
# to have an autologin=llimllib line
#
# oddly, there was an uncommented autologin line with `anon` specified already;
# I changed it to llimllib; this worked.

# why is shutdown hanging on unmounting?
#
# grepping around, I see that /etc/runit/3 has:
#
# if [ -z "$VIRTUALIZATION" ]; then
#     msg "Unmounting filesystems, disabling swap..."
#     swapoff -a
#     umount -r -a -t nosysfs,noproc,nodevtmpfs,notmpfs
#     msg "Remounting rootfs read-only..."
#     mount -o remount,ro /
# fi

# So it's probably the umount that failed? (but what is swapoff? swapon(8) says
# that `swapoff -a` disables all swap drives. _probably_ not what's at fault?)

# I added debugging to it to make sure that it's not the swapoff line. that
# umount line means "unmount everything that's not of type sysfs, proc,
# devtempfs, or tmpfs"

# ah ha! here's the issue: https://github.com/void-linux/void-runit/issues/16
# a quick read suggests that there's no easy way to work around it - it will
# get overwritten on system updates? have to hack around with it a bit.

# but there is a good workaround! It's to have a service that mounts your
# mounts when the network is available, and unmounts them when the system shuts
# down. It took a long time to find, and I wrote 2/3 of a replacement, but
# `netmount` does exactly that. I added the install and linking steps above.

# User Services
# --------
# It can be handy to run your own services. For example, I'm
# running one that checks for my keyboard being plugged in and enables a pot as
# volume control when it is.
#
# To do so, create a `llimllib-services` service directory in /etc/sv/, with a
# run file:

mkdir -p /etc/sv/llimllib-services && echo "
#!/bin/sh
exec 2>&1
exec chpst -ullimllib runsvdir /home/llimllib/service" > /etc/sv/llimllib-services/run \
    && chmod a+x /etc/sv/llimllib-services/run

# then create a `~/service` directory, and you can put user-controllable
# services in it by making a directory with a `run` script
#
# void docs: https://docs.voidlinux.org/config/services/user-services.html

# taking a screencast
# -------------
#
# I tried using `peek` to take a screencast, but it had terrible flickering and
# tearing. Lots of googling later, I learned that I might need to change my
# video acceleration method from the default "SNA", to the slower but
# functional "UXA". To figure out how to do _that_ was mostly a wild-assed
# guess that came down to:

echo "Section "Device"
  Identifier "Intel Graphics"
  Driver "intel"
  Option "AccelMethod" "UXA"
EndSection" > /etc/X11/xorg.conf.d/20-intel.conf 

# then restarting


# TODO:
# * I used the xbps-src method to install mdbook and mdbook-linkcheck, which
#   clearly uses cargo; but cargo's not on my path. Where is it?
# * rn, dragging an icon in the start menu reliably crashes cinnamon
#   * ctrl-alt-fn-f2 to get to a tty, then `sudo sv restart lxdm` to restart
#     cinnamon
