 # Arch Linux
 
+ughhhhhh had to reinstall the test vm like 5 times. finally got lxqt with virtualbox driver to load the desktop
+but networking is not working. Perf is kinda shitty. UI is shitty. QT sucks. I hate linux.
+
+##  Setup
+
+* Installation guide https://wiki.archlinux.org/title/Installation_guide
+    * Can go through manually or use the new guided installer: `archinstall`
+
+* use btrfs file system
+    * I guess I should enable compression but I'm  not sure how it affects perf.
+
+* I tried Luks disk encryption in a VirtualBox VM and I couldn't get into the
+  desktop. Locks up on login. Not sure if it's related to this...can try
+  encryption on a real install.
+
+* desktop environment
+    **VM Test**
+        * lxqt, vmware graphics driver, lightdm-slick-greeter
+
+    * lxqt - X11 based. I was using lxde in the past but it was abandoned by
+      the original team. They made lxqt. It's QT based which is lame but might
+      be fine. This is lightweight and I have my old configs (for LXDE and
+      OpenBox) which might still be usable.
+
+    * sway - Wayland based. Martins uses this. I want to try it but it lacks
+      nvidia driver support and requires something called wlroots?  I don't
+      want to mess with this in my testing vm. Maybe later if I do a proper
+      Arch install.
+        * https://github.com/tyqualters/sway-nvidia-guide
+        * https://www.reddit.com/r/archlinux/comments/yuu7ra/whats_the_difference_between_nvidia_and_nvidiaopen/
+        * using seatd for hardware device collection

+if you don't want upstream releases then obviously arch is not for you, but
+they have simple solution for that - aur, you can keep managing your
+dependencies separately from system packages
+
+Martins uses Sway:

+no, .bashrc
+I have autologin on tty1

+      export XDG_SESSION_TYPE=wayland
+      export XDG_CURRENT_DESKTOP=sway
+      exec systemd-cat -- sway
+    fi
+
+Saw this on reddit: sudo pacman -S wayland xorg-xwayland xorg-xlsclients sway swaybg swaylock waybar wofi -y
+What is wofi ?

-* Full disk encryption with Veracrypt
 
 * Store /tmp in RAM
+    * 2024: looks like it's done by default. See https://wiki.archlinux.org/title/Tmpfs
 
 * Move browser cache directories to /tmp as a means of reducing file writes on SSD

     * Expand the cert tree -> click on `Trusted Root Certificate Authorities` -> `Certificates`
     * Before deleting a certificate, export it as a backup in case it's needed for system operation. Can also make a
       restore point before making any changes.
+      * Note: I'm putting exports in backups/windows_certificates
 
 * Maybe disable swapfile
     * Not a good idea to have this turned on for SSDs since it's extra writes, and writing to an SSD degrades the drive. Probably best to put this on a spinning disk.
