+  rm 'Login Data-journal'
+===== Image/Photo Editors =====
+Seems like I'm going to be preferring pixlr (online) or Krita (local).
+^ App ^ Online ^ Notes ^
+| -> **[[https://pixlr.com/|pixlr]]** | Online | Good  image editor. Pretty intuitive. No arrows. |
+| [[https://www.photopea.com/|Photopea]] | Online | Has arrows. Width is limited to a narrow max. |
+| [[https://excalidraw.com/|Excalidraw]] | Online | Pretty great diagram drawing tools. Not a photo editor, but making a note here. |
+| **-> [[https://krita.org/en/|Krita]]** | Local | Promising image editor. Arrows in vector layer. Draw line then change properties. |
+| [[https://www.gimp.org/|Gimp]] | Local | The huge standard. GNU Photoshop. More than I usually need. |
+| [[https://www.pinta-project.com/|Pinta]] | Local | Inspired by an old version of Paint.NET. Installed, but unsure. Arrows are easy. |
+After installing Krita, add a desktop launcher to make it more GNOME/rofi/drun friendly. [[https://amanabt.github.io/blog/tech/2022/03/11/installing-krita-from-appimage-ubuntu-20_04.html|Extract the .desktop from the appimage]] to $HOME/.local/share/applications or manually make a [[https://github.com/davatorium/rofi/issues/326#issuecomment-174301525|.desktop file]] in $HOME/.local/share/applications.
+I put the krita appimage in ''/usr/local/bin'', the .desktop in ''$HOME/.local/share/applications'', and a 256x256 .png in ''/usr/share/pixmaps''. The .png is untested.
+===== DejaVu Sans for Powerline Font =====
+First install the Powerline Font:
+  git clone --filter=blob:none -b master --single-branch https://github.com/powerline/fonts.git
+  cd fonts
+  ./install.sh "DejaVu Sans"
+Then your terminal emulator can use it.

-===== Gnome (Desktop Env) Usability Issues =====
+The tiny Wi-Fi connection dialog is [[https://wiki.archlinux.org/title/Dunst|Dunst]] which has its own config [[https://www.reddit.com/r/i3wm/comments/b1s18p/how_do_you_change_the_default_font_size_of/|reddit thread]].
-[[https://community.frame.work/t/fingerprint-keyring/19230/2|Using the fingerprint reader doesn't unlock keyring]].
+I thought the media keys (Function keys) weren't working. I added "blacklist hid_sensor_hub" to [[https://community.frame.work/t/solved-guide-12th-gen-not-sending-xf86monbrightnessup-down/20605|framework-als-blacklist.conf]] for the brightness keys. (But I should undo that change and see if they still work now. Make sure the "fn" key wasn't in the other mode.)

+==== Suspend and Hibernation ====
+A note on battery life. Frame.work batteries work best at charges between 80% and 30%. I went into BIOS ([[https://knowledgebase.frame.work/how-do-i-enter-the-bios-on-the-framework-laptop-HydmWf5Ad|pressing F2 on start up]]) and set maximum charge to 90%.
+Suspend worked out of the box. See This PSA from frame.work: [[https://www.reddit.com/r/framework/comments/19bf3ki/linux_suspend_and_amd_reminder/|Linux Suspend and AMD Reminder]]. Per that PSA and [[https://community.frame.work/t/tracking-linux-battery-life-tuning/6665/536|[TRACKING] Linux Battery Life tuning]], I ran [[https://gitlab.freedesktop.org/drm/amd/-/blob/master/scripts/amd_s2idle.py?ref_type=heads|amd_s2idle.py]]. It ended with:
+<code>
+🚦 RTC driver `rtc_cmos` configured to use ACPI alarm
+Explanations for your system
+🚦 rtc_cmos is not configured to use ACPI alarm
+	Some problems can occur during wakeup cycles if the HPET RTC emulation is used to
+	wake systems. This can manifest in unexpected wakeups or high power consumption.
+For more information on this failure see:
+	https://github.com/systemd/systemd/issues/24279
+</code>
+So per the third link above, I [[https://askubuntu.com/questions/19486/how-do-i-add-a-kernel-boot-parameter|added a kernel boot parameter]] by editing /etc/default/grub like so:
+<file bash /etc/default/grub>
+...
+GRUB_CMDLINE_LINUX_DEFAULT="quiet splash rtc_cmos.use_acpi_alarm=1"
+...
+</file>
+And then I ran ''sudo update-grub'' per the file's instructions.
+Enable suspend-then-hibernate. To hibernate, [[https://community.frame.work/t/hibernation-using-it/6060/11|you need swap to be as big as RAM, then update GRUB]]. (32GiB in my case.) You may also have to [[https://community.frame.work/t/battery-drain-on-suspend-sleep-with-linux/42395/4?u=david_blume|disable Secure Boot]].
+I had a 2GiB /swapfile, and this is how I resized it:
+<code bash>
+~$ sudo swapoff /swapfile
+~$ sudo dd if=/dev/zero of=/swapfile count=32K bs=1M
+...
+~$ sudo mkswap /swapfile
+~$ sudo swapon /swapfile
+</code>
+Then it became time to update the kernel boot params again with the UUID of the volume with the swapfile, and the physical offset of the swapfile.
+<code bash>
+$ blkid
+/dev/nvme0n1p2: UUID="de9f6aca-85a1-461b-b8b8-15f44441f64d" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="121db783-104a-4138-b7c2-c0451ab10454"
+$ sudo filefrag -v /swapfile | head
+Filesystem type is: ef53
+File size of /swapfile is 34359738368 (8388608 blocks of 4096 bytes)
+ ext:     logical_offset:        physical_offset: length:   expected: flags:
+:        0..    2047:    1257472..   1259519:   2048:
+</code>
+That means, in my case, I add this to ''/etc/default/grub'''s ''GRUB_CMDLINE_LINUX_DEFAULT''.
+<code>
+resume=UUID=de9f6aca-85a1-461b-b8b8-15f44441f64d resume_offset=1257472
+</code>
+Don't forget to ''sudo update-grub''.
+Then I enabled this line in
+<file bash /etc/systemd/logind.conf>
+HandleLidSwitch=suspend-then-hibernate
+</file>
+Everything is still commented out in ''/etc/systemd/sleep.conf'' (Also see [[https://community.frame.work/t/tracking-suspend-on-linux-drains-a-lot-of-battery-compared-to-other-laptop/24737/60|suspend drains battery]]). May need to turn some of those lines on.
+==== Future Config Tips ====
+You can use ''xprop'' to learn the Window Class (the second value) for assigning apps to workspaces
+  assign[class="Rhythmbox"] $workspace10
+If you keep accidentally typing Ctrl+Shift+C in Chrome, [[https://askubuntu.com/questions/604434/chrome-disable-or-change-keyboard-shortcut-ctrlshiftc-developer-tools-console|you can disable it with shortkeys extension]]:
+Install [[https://chrome.google.com/webstore/detail/shortkeys-custom-keyboard/logpjaacgmcbpdkdchjiaagddngobkck|shortkeys]] and set (and save) the following:

+  * Behavior: Run JavaScript
+  * Javascript code to run: ''document.execCommand('copy')''
