 +===== 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.
