I found a huge source of applications that are all formatted to work well on the screen of my Librem 5. Most of them install and run well also. I did a search for a Raspberry Pi Store. What I found has just about every program you might find in a large desktop Linux distribution (pretty much everything in every category). After you install the store from a terminal window, you can open that store up in graphical form from the apps drawer. Most of those apps are working and will show up in the apps drawer after you install them. Every app warns that PureOS is not supported when you select it for installation. Then you install it anyway, and it works anyway most of the time. The Thunderbird email program looks good on my screen and will be the first non-desktop program capable of accessing my Cox email after they added in the heavy duty email authentication requirements a few years ago, if it works. Already, my Librem 5 is starting to look somewhat like a normal cell phone now that there are so many new apps for it.
These apps include Virtual Box and Qemu. Some of the programs appear to be Windows programs that run under Wine and handle all of the complex configuration details on their own when you install them. Most of these apps install quickly. But Notepad++ is currently installing Wine and several dll files in to Windows paths (in my terminal window) and it’s been installing for twenty minutes now. There are also codecs and development tools there. It’ll take me a while to fully explore this. Enjoy !
Update: I am finding that some of these programs take a while to open and some of them don’t respond at all after they come up. But still, some of them work just fine.
Here is how to install it to your Librem 5 starting from a terminal window.
sudo apt install git
wget -qO- https://raw.githubusercontent.com/Botspot/pi-apps/master/install | bash
Then go to the store’s web page
