I am using this page to keep track of "stuff". I'm new with Arch. My Lenovo ThinkPad X1 Carbon (Gen 6) just arrived. Time to move away from MacOS once and for all (initial idea mainly because of the new Apple keyboards).

Installation

  • Followed mainly https://gist.github.com/heppu/6e58b7a174803bc4c43da99642b6094b
  • Took the cryptsetup from Dm-crypt/Device_encryption#Encryption_options_for_LUKS_mode
  • Then tried to fix the S3 sleep with https://delta-xi.net/#056
    • systemd-boot needs two initrd lines in the arch.conf
    • s3 works now very well
  • Energy consumption
    • Measured with custom script. Basically determining idle power consumption at different screen brightnesses
    • Enabled tlp.service and tlp-sleep.service => no problems with trackpoint and touchpad after waking up
  • SSD: TRIM is disencouraged for NVMe SSDs by Intel says: https://wiki.archlinux.org/index.php/Solid_State_Drive/NVMe#Discards
  • Making the system a bit more secure
    • Disable root login
    • Change default umask to 077
  • Enable ntp time synchronization: timedatectl set-ntp true
  • Use ZSH and oh-my-zsh
  • Undervolting
  • Created a nice .dotfiles repo and started configuring vim tmux zsh
  • Printing with cups
    • Add yourself to the sys group
    • Use gutenprint drivers
    • Add printer through the web interface
  • Setting up system snapshots that show up during boot
    • Goal: Create an automatic or manual snapshot that can be restored during boot, if needed
    • Creation: sudo lvcreate --snapshot --size 30G --name root-snap /dev/vg0/root
    • Restore: sudo lvconvert --merge /dev/vg0/root-snap => Will automatically merge the snapshot back at the next reboot.

ToDo / Wishlist

  • Stability testing
    • systester-cli -gausslg 16M -threads 8 -bench -turns 50 -log (first try with -120mv ran for 1 minute before crashing)
    • Settled to -100mv on CPU (as -110 had 3 errors after 60 Minutes), -110 on GPU => No graphic failiures with unigine-haven and systester at the same time
  • Changing the thermal paste?
