NOTES.md

File for collecting notes on various fragments of system configuration that either can't be made deterministic or I haven't yet spent the time to try.

Linux

Sublime

• Better to install via native package managers than flathub due to better updates. https://www.sublimetext.com/docs/linux_repositories.html#yum
• Preference sync: location for user preferences is ~/.config/sublime-text/
• If installing via flathub:
  • Sync: user preferences in ~/.var/app/com.sublimetext.three/config/sublime-text-3/Packages (on Fedora35 Sublime3)
  • binary must be symlinked for subl command ln -s /var/lib/flatpak/exports/bin/com.sublimetext.three /usr/local/bin/subl. From: flathub/com.sublimetext.three#24

Tweaking the desktop

• Gnome extensions: very useful. I should figure out how to save ones I am using to dotfiles.
• Gnome Tweak Tool

Window Management

• gTile is like Divvy but better.
  • how to export settings: gTile/gTile#121

Special Character input

Ibus installed by default: https://wiki.archlinux.org/title/IBus#Emoji_input

Images

• image viewer:
  • gThumbnail (chosen) - more capable image viewer than the built in one
  • alternatives: XnView, Shotwell, Darktable (full photo organization)

Framework Laptop

Acceleration

• https://community.frame.work/t/linux-battery-life-tuning

GPU rendering with Firefox and Chrome (WIP)
    Install igt-gpu-tools
    Ensure that intel_gpu_top is showing GPU usage when watching video on browser.
    Firefox 92 → about:config → layers.acceleration.force-enabled

Power

• Getting deep sleep working: https://community.frame.work/t/fedora-34-on-the-framework-laptop/2723/49?u=bogdan_vitoc
  • but keeping my luks uuid for disk encryption
• Installed TLP
• SSD suspend battery life: sudo grubby --update-kernel=ALL --args="nvme.noacpi=1"

Bluetooth Issues

Disabling autosuspend of bluetooth devices: sudo grubby --update-kernel /boot/vmlinuz-5.15.6-200.fc35.x86_64 --args="btusb.enable_autosuspend=0" from: https://bugzilla.redhat.com/show_bug.cgi?id=1589548 how to add kernel command line args: https://fedoramagazine.org/setting-kernel-command-line-arguments-with-fedora-30/

problems with bluetooth adapter after "warm boot" (i.e. restart): https://bugzilla.kernel.org/show_bug.cgi?id=213829#c26 supposedly fixed in kernel 5.15.6-ish

This was fixed by updating to 5.16.11 (though I also disabled autosuspend and didn't test independently so could have been that).

Displays

Had an issue with my Dell U2421E monitor being locked to 30hz when used over USB-C-to-C w/ PD. Swapped for HDMI-HDMI, no issue. Displayport-to-USB-C, no issue. Back to USB-C-to-C, now no issue! Works with 60fps.

Issue with U2421E blackscreening. https://bugzilla.kernel.org/show_bug.cgi?id=211807
