1. Changing the resolution of the GRUB

This machine uses 3k resolution which is quite hard to the eyes, and dos prompt has a hard time drawing the menu. To change this you need to go to /etc/default/grub and


Then save and run sudo update-grub to apply the resolution change

2. Changing the resolution of SDDM

Like the GRUB the login screen also opens in the highest possible resolution, which is something I really don’t like. To decrease it:

  1. Find the monitor’s device name from Displays menu. (Mine was eDPI1)
  2. Go to /etc/X11/xorg.conf.d and sudo touch 50-monitor.conf
  3. In the touched file enter these lines:
	Section "Monitor"
        	Identifier   "eDP1"
        	Option "Enable" "true"
        	Option "PreferredMode" "1920x1080"

By doing this we’ll order the SDDM to render in 1920x1080 which is my desktop resolution.

3. Gem installation which reflects on bash

If you want to do a gem installation, like Jekyll, the usual command gem install jekyll doesn’t register on the bash. In Manjaro you need to install your gems in this way to make them usable on the command line:

sudo gem install <gemname> --no-user-install

Warning: This is done deliberately to separate the Pacman’s gem installs (if it does) from your own gem installs. Caveat Emptor!
