The rust Pop_OS! cosmic desktop app written in Rust by the team an system 76 is currently in pre alpha but you can test it out. It’s probably not ready to use as your daily driver at present. Many thanks to Levi Portenier for his help via the Mattermost chat to allow me to get started with this.

Installation

make sure your system is up to date using the command:

Enable Wayland by editing the /etc/gdm3/custom.conf and place a ‘#’ at the beginning of the line that reads WaylandEnable=false. Log out and select your username there should be a cog in the bottom right corner of the password entry page clicking on that should give the option for Pop on Wayland at the time I tested this it was not very stable and the tiled desktop did not work.

Once wayland has been enabled you can install the desktop from the standard repos using the command:

Log out and click on your user name, the cog on bottom right of the password entry screen now has a COSMIC option. Select that and enter your password.

At the time of writing there’s no dock available, the initial screen is quite minimal. At present keyboard control is required. Here are the shortcut I found (or was pointed to by Levi).

Clicking on the Power button displays a menu from there you can log out, power off and access the Cosmic Settings app (this is still in very early development so options are limited). There does not appear to be any way to adjust the resolution of the screen. I tested this in a VM and could not see any way to make the screen larger than 1024 x 768. According to Levi, this can be configured in /etc/cosmic-comp/config.ron but the default version does not contain any settings for resolution. The standard Gnome Settings app is still available from the application library but as you would expect the settings are not applied to the COSMIC desktop.

The window chrome does not have a maximise button – you can maximise by double clicking on the title bar. However maximised at present seems to cover the top bar.

The default keyboard layout seems to English US. I could not see a way to change this.

Troubleshooting

Run minion in debug mode

Can’t perform a sudo salt ‘minion-name’ test.ping:

Log on to minion and set to run in debug if no communication from master check the value of `source address` in /etc/salt/minion.d/base.conf

Upgrading to Onedir (on Ubuntu)

Salt classic is being retired – it will not longer be packaged after version 3005. Onedir (which packages everything, including python, required to run salt in one directory) is the future. To upgrade a new gpg key is required.

For a long time, I thought why use a different node package manager like yarn – “npm (the package manager that’s installed when you install node) does the job, why make it more complicated?” Then I came across a project that said it installed best with pnpm, I decided to check it out and found it does add value. I’ve switched to using pnpm because it allow management of node which was previously a bit of a faff. Also, when one includes a package in a project it stores the package version in a central repo and adds a link to that package/version so next time you reinstall or use that package / version in another project it does not need to be downloaded again. It also takes care of global installations without using sudo or extra configuration. Check out the website for more benefits.

What follows is a very basic introduction to pnpm on Linux systems partly as an aid memoir to myself but hopefully you find it helpful too! These instructions should work for most Linux distros but I’ve only tried it out on Debian based ones so far.

Installing if you don’t already have node installed

If you don’t have node installed you can install pnpm and use that to install node rather adding the node repo to your system page manger and installing from there. To install so that you can manage node use the command:

curl -fsSL https://get.pnpm.io/install.sh > pnpm-install.sh
# view the file to make sure you're happy running it on your computer
sh ./pnpm-install.sh

or if you don’t have curl you can use “wget -O- https://get.pnpm.io/install.sh | sh -” instead.

You can install the current LTS version of node using the command (other options in place of “lts” allow installing other versions, see the pnpm website for details):

pnpm env use --global lts

Installing if you already have node installed

You can use the script above if you’ve already got node installed however there are also a couple of other If you have a recent version node (versions 16.13 onwards) you can use corepack, run the commands:

corepack enable
corepack prepare pnpm@latest –activate

Or you can install using npm:

npm install -g pnpm

Getting started

Command are often similar to their equivalent npm command and should be run from the project directory.

I find tab completion very useful, to install it for bash zsh or fish shells use the following (and then reload your shell using e.g. source ~/.bashrc or log out and back in again):

pnpm install-completion

To start a new project:

pnpm init

To convert an existing project using a package-lock.json:

pnpm import

To install an existing project – this read from an existing pnpn-lock.yaml to get version information (if it exists, it it does not exist it will be created – you should add this file to your :

pnpm install

Adding dependencies to a project is slightly different to npm. To add a development only dependency use the add command and append “–save-dev” as below, you can optionally specify a tag, version or version range:

pnpm add <package name>[@<tag>|@version>|@<version range>] –save-dev

Add a production dependency (the default add action)

pnpm add <package name>[@<tag>|@version>|@<version range>]

Removing the installed packages is similar to npm (though as pnpm creates links to a central repository it only removed the links to these packages)

pnpm remove <package name>

To run a script you can use the same syntax as npm (pnpm run <script defined in package.json>) but unless your script is a keyword used by pnpm you can simply use:

pnpm <script defined in package.json>

Thanks for reading

I find pnpm much is an improved package manager compared to npm, hopefully you’ve found this useful as an introduction.

Enjoy!
