This is guide on how to create VRAM (Video-RAM disk to use your videocard memory as additional disk).
This can be used for testing, benchmarks, etc.
The manual is for Nvidia card. However, it will be +- similar for ATI/AMD and Intel cards, the only thing you need to change is the "opencl" packages (for ATI/AMD it would probably be opencl-mesa package while for intel - intel-compute-runtime).

Doing this on Arch (Manjaro) system recent (Mikah).
Additional requirements:

• pikaur (or use your own faviourite AUR helper instead!)
• several hundreds megabytes free on hdd/ssd/whatever
• several GBs of memory on your GPU to utilize the VRAM disk (ideally, 4, 8 or more GBs)

Game information Worms W.M.D.

Distribution name and version where applicable Manjaro 20.1.1 (Mikah)

Problem description Worms doesn't launch out of the box without two small tweaks. When launching Worms W.M.D. in Manjaro and Archlinux, you need to do two things:

1. Install this apps: sudo pacman -S libcurl-gnutls libidn11 qt5-base qt5-xcb-private-headers(If you are on any other distro then Arch, you can skip this step. At least this is reported to be OK to skip for Linux Mint)

#!/bin/bash
# Requirements: linux, docker, grep, awk
# This script removes all "Down" (off) nodes from Docker Swarm
# Useful to clean stuff from time to time, if you have auto-joining nodes for example
sudo docker node rm $(sudo docker node ls | grep Down | awk -F" " '{ print $1 }')

My Laptop is Alienware R3 17" with external amplifier card "Nvidia RTX 2070" but it should work for other Nvidia's, as well.

The process is pretty easy.

0. Turn off laptop. Connect the external amplifier with GPU and electricity, as well as connect laptop to electricity. Turn everything back ON & boot into Manjaro or Arch.

1. Ensure the system is fully updated:

sudo pacman -Syyu or just update the system by using GUI "Software Update" from system menu.

# Let's say you want to connect to remote host (via SSH) as normal user and then execute command there as root.
# This way, you can execute root commands on the server, even without remote root access.
# You also want your command to continue as well as disconnect from the remote host.
# In the example below, we will run a docker container which requires the NET_ADMIN (root access) as example command ($cmd)
# This can be achieved by using such tools as "screen" and "sshpass", so requirements are installing them:
# `sudo pacman -S screen sshpass` # Command for Arch/Manjaro
# `sudo apt install screen sshpass` # Command for Debian/Ubuntu
# `sudo dnf install screen sshpass` # Command for Fedora/CentOS
# After you have this requirements, you need to specify your variables:

#!/bin/bash
# This script generates a vertical strip of flags, about 200 px wide
# Replace countrues variable with the ISO country names you want
# It automatically downloads flags from github repo

    #count=(1  2  3  4  5  6  7  8  9  10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31)

Step 1. Download recent RancherOS.iso file from the github repo

Step 2. Burn RancherOS.iso with dd, dcfldd or BalenaEtcher

Step 3. Change the BIOS setting for your device to boot from USB flash and insert it, then reboot

Step 4. Run installation (replace the /dev/sda with your memory device and password with anything you like)

sudo ros install -f -d /dev/sda --append "rancher.password=original"

Result: RancherOS is installed & the system user "rancher" will have password "original" in the case above.

Please run the following commands to resize a partition.
IMPORTANT NOTE: Don't forget to change partition address from /dev/sdb2 to your actual partition!
CHANGES ARE DONE IN TWO OR THREE PLACES.
Example below are for /dev/sdb2 partition which is called like "/dev/sdb 2" for growpart
and like "/dev/sdb2" for resize2fs & e2fsck.
Requirements: * growpart; * resize2fs; * e2fsck if disk requires checking.
Install growpart in arch/manjaro: pikaur -S growpart (resize2fs and e2fsck are usually bundled with OS)

sudo growpart /dev/sdb 2
