Dotfiles

Setting up dotfile from scratch

From Github UI console create a new repository called dotfiles and initialize it with a README.md and LICENSE (optional)
Install Git, Git SSH Keys and dotdrop using the setup install script.
Update PATH export PATH=${PATH}:${HOME}/.local/bin
Create a new repository dotfiles on github and initialize with readme
With Git available and ssh-agent populated with the github key, we clone the dotfiles repository git clone [email protected]:hemenkapadia/dotfiles.git in $HOME directory. This would only have your README and LICENSE (if selected) for now.

Kernel settings for installation

Use a live usb to try Ubuntu before installing. Boot from the live usb. On the GRUB screen highlight the "Try Ubuntu ...." option and press e. Update kernel parameters by adding options before quiet splash such that the line should read as below

nogpumanager nomodeset i915.modeset=1 quiet splash

Note: On HighDPI screen machines there is a known issue whereby Ubiquity (ubuntu installer) craashes at the copying files step i.e. immediatly after the user setup screen. The cause and workaround are discussed in other gist post

Persist GRUB configuration

Post installation, to avoid updating the above mentioned kernel options each time the system is booted, edit GRUB configuration file sudo vi /etc/default/grub and make th

	#!/bin/bash

	# Check sudo.
	# If credentials not already cached, ask for password and cache credentials.
	# If already cached, increase sudo timeout by 5 min
	sudo -v && exit 1 'Sudo access needed to execute this script'


	# First update
	echo "Updating apt list ...."

	Installing Ubuntu 18.04 resulted in an error with the Ubiquity process crashing while copying files. As a result files possibly were not copied on the drives as intended.

	I tried following the GRUB recovery process mentioned at https://www.linux.com/learn/how-rescue-non-booting-grub-2-linux%20 but the /boot partition did not include the vmlinuz files hence this approach had to be abandoned

	Had to revert to the process mentioned at https://www.easeus.com/partition-manager-software/fix-uefi-boot-in-windows-10-8-7.html and used the Windows recovery drive created earlier.

	Followed the below process

	2.1 Use diskpart to repair Windows 10/8 UEFI

	1 sudo apt-get update
	2 sudo dpkg --configure -a
	3 sudo apt-get update
	4 sudo apt-get upgrade
	5 clear
	6 sudo -lshw -class network
	7 sudo lshw -class network
	8 lshw
	9 sudo lshw
	10 lshw -calss network

	While installing Ubuntu LTS on a laptop with HighDPI screen (and potentiall selecting Something Else option for the Installation type, ubuquity used to crash with the below error while copying files. This happens post the initial user creation details are provided.

	The way to resolve this was to before starting the installation, we should Try ubuntu and in that modift the diaplay setting as shown below
