# after adding, notification will appear on desktop to confirm
#
# syncing folder. from phone to desktop: select desktop in the
# folder on phone\'s sync options, notification will appear in
# desktop\'s web ui within a minute. For the reverse, the
# notification will appear in android\'s notifications, you have to
# swipe down and tap it to add the folder. It won\'t appear in the
# syncthing ui, which would be intuitive, but don\'t wait for it
# there. The notification may not work, instead open the web gui
# from in the app, there should be a notification within there.
#

# if I was going to create a persistent vm, i might do it like this:
# variant=something  # from: virt-install --os-variant list
# s virt-install --noautoconsole --graphics spice,listen=0.0.0.0 \
  #   --disk=/a/images/some_name.qcow2,bus=virtio --vcpus 2 -r 4096 -w bridge=br0 \
  #   -n some_name --import --os-variant $variant --cpu host-model-only


# for brother HL-2270DW, this worked:
# https://askubuntu.com/questions/1067234/cant-use-wireless-brother-printer-2270dw-ubuntu-18-04
# /a/opt/linux-brprinter-installer-2.2.2-1
# answer n when it asks about uri.
# Then go to cups, delete the existing printer, added on with dnssd url. browsed to
# ppd at /usr/share/ppd/HL2270DW.ppd, which is duplicated at /usr/share/cups/model/HL2270DW.ppd
# ppd file got installed from bash -x ./usr/local/Brother/Printer/HL2270DW/cupswrapper/cupswrap,
# which I downloaded from their driver. but dont do that again, i copied it to /a/opt/HL2270DW.ppd,
# use that.

# I had to reset it to use wired instead of wifi. it only uses 1 at a time. boot with go button held, after lights turn off, tap go 6 times.
# Then it was already configured, but if i needed to, go to its web ui, default pass is "access".
