Stuff to do after Linux installation

Enable SyRrq for the magic REISUB spell when the system freezes.
Disable freaking system beep. On my laptop it’s extremely loud.
Remove garbage from Linux autostart. I removed this in KDE Fedora:

# Limit CPU temp

For my garbage Lenovo laptop. It has extremely buggy BIOS which doesn’t control the fan properly and CPU gets overheated as a result.

Download and compile RyzenAdj.

Add a small script to KDE autostart menu:

#!/bin/bash

sudo /opt/RyzenAdj/ryzenadj --tctl-temp=63 && notify-send "Successfully set tctl_temp to 63"

# Wait for the GUI to be ready
# while [[ ! $(pgrep plasmashell) ]]; do sleep 1; done
# sudo /opt/RyzenAdj/ryzenadj --tctl-temp=62 && notify-send "Sucessfully set tctl_temp to 62"

Also set it to use sudo without password using this method. Using sudo visudo add this to the end of the file:

psharen ALL=NOPASSWD: /opt/RyzenAdj/ryzenadj

You can also add a custom shortcut to launch it (Meta + T). But after suspend/wakeup cycle this setting breaks. And there’s no way under KDE to execute something after wakeup, AFAIK. So I used this method and added a small script to /lib/systemd/system-sleep/:

case $1/$2 in
  pre/*)
    # echo "Going to $2..."
    # Place your pre suspend commands here, or `exit 0` if no pre suspend action required
    exit 0
    ;;
  post/*)
    # echo "Waking up from $2..."
    # Place your post suspend (resume) commands here, or `exit 0` if no post suspend action required
    # while [[ ! $(pgrep plasmashell) ]]; do sleep 1; done
        /opt/RyzenAdj/ryzenadj --tctl-temp=63
    ;;
esac

To make it work, change default TTL: How to change the default TTL of TCP/IP packets.
