-===== Learn Shortcuts =====+===== Google Chrome Passwords and Autofill =====
  
-Consider vim leader (\), vim window (C-w), tmux leader (C-a)...+Via an [[https://unix.stackexchange.com/a/606531|answer to "chrome does not save my passwords"]]:
  
-How to change workspaces? (Ctrl+Alt <- or ->)+> Sometimes a couple of login files get corrupt, and stop google-chrome from saving the passwords. To fix it, close google-chrome. Terminal to the following directory and remove the two files, Login Data and Login Data-journal. 
 + 
 +  cd ~/.config/google-chrome/Default 
 +  rm 'Login Data' 
 +  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.

 + 
 +==== 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:        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: 
 +  * Keyboard shortcut: ctrl+shift+c 
 +  * Behavior: Run JavaScript 
 +  * Javascript code to run: ''document.execCommand('copy')''
