+===== 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.

 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]].
-  * [[https://community.frame.work/t/resolved-amd-framework-arch-linux-suspend-wakes-every-5-minutes/39022|[RESOLVED] AMD Framework - Arch Linux - Suspend wakes every 5 minutes]]
+I had a 2GiB /swapfile, and this is how I resized it:
-  * [[https://community.frame.work/t/responded-amd-hot-while-suspended-in-suspend-then-hibernate/39050|[RESPONDED] AMD - Hot while suspended in suspend-then-hibernate]]

+~$ 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

+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

+Don't forget to ''sudo update-grub''.

-Everything is still commented out in ''/etc/systemd/sleep.conf'' and ''/etc/systemd/logind.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.

+====== Distro Upgrade ======
+Software Updater: "Not enough free disk space"
+Thread at Slack. First try "sudo apt-get autoremove --purge", and if that doesn't work, then to see the installed kernels:
+<code>
+$ dpkg --list | egrep "^ii +(linux-image|linux-headers)"

+And then choose the old ones (comparing with what's on /boot) to manually remove...
+<code>
+df -h /boot
+ls -l /boot
+# Install aptitude to see why it was installed... (Output wordy, says whether manually installed, dependencies)
+aptitude why -v linux-headers-5.11.0-46-generic
+sudo apt purge linux-headers-5.11.0-46-generic  # picked a few old looking ones
