Mint 19.2

disable kdb backlight to avoid lockup at boot:
ln -s /dev/null /var/lib/systemd/backlight/platform-dell-laptop\:leds\:dell\:\:kbd_backlight

It's actually this command, but I did not manage to mount up the system for systemctl to work:
sudo systemctl mask systemd-backlight@leds\:dell\:\:kbd_backlight.service

For wifi to work the Broadcom 3rd party driver install is needed (broadcom, what did you expect? - closed drivers..)

Chrome Install (oh its 64bit only, and Im having a 32bit system, bummer... - I used "chromium-browser" instead):
$ sudo sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
$ wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
$ sudo apt-get update
$ sudo apt-get install google-chrome-stable

Citrix (installed the deb packages web, and workspace from citrix):
Install Checker:
sudo /opt/Citrix/ICAClient/util/hdxcheck.sh
ica open test failed with libcurl error:
/opt/Citrix/ICAClient/wfica.sh

sudo apt-get install libcurl3

Might need this:
sudo ln -s /usr/share/ca-certificates/mozilla/* /opt/Citrix/ICAClient/keystore/cacerts/
sudo c_rehash /opt/Citrix/ICAClient/keystore/cacerts/

After this citrix worked when I selected "Citrix Workspace App" in firefox

Set default editor to vim-tiny (which is installed):
update-alternatives --config editor

Im running on a dell inspiron mini, which is fanless, so it runs pretty hot, to check temps:
setup sensors (I answered all yes, then yes to add stuff to /etc/modules):
sensors-detect
To check temps:
sensors 

check on the cpu:
inxi

cpu core temps:
#grep MHz /proc/cpuinfo

/etc/default/grub : (this did not work)
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash processor.ignore_ppc=1"
# update-grub

to set clock speed:
apt-get install cpufreq-selector

to lock speed:
cpufreq-set -f 1000 cpu0
cpufreq-set -f 1000 cpu1

change gov:
cpufreq-set -c 0 -g performance
cpufreq-set -c 1 -g performance

cpufreq-set -c 0 -g 

Persistent changes:
/etc/init.d/cpufrequtils

conservative

In /lib/systemd/system/ondemand.service disable "/lib/systemd/system/ondemand.service" or disable the ondemand service.

For sudo to work without a password (someone might say I like to live dangerously):
I just create a file under "/etc/sudoers.d" as somefile
and add:
username ALL=(ALL) NOPASSWD: ALL
