Fedora 39 : About Penpot online tool.

Designers and developers can finally work in unison to build beautifully designed software experiences that truly scale up.

Penpot is the Open-Source Design & Prototyping Tool for Product Teams.

If you have worked with Adobe XD or similar software, then it performs the same functions.

I haven't tested it very thoroughly, but I can tell you that it works very well and is open-source and free.

I haven't seen anything about Bootstrap in the library of bookstores and templates, but there are quite a few in other areas with a pretty good design.

You can test it on the official webpage.

See these videos from the official youtube channel:

News : Elections for Fedora team.

News : Fedora 39 i18n test week starting 5th September.

We will be having the Fedora 39 i18n test week starting 5th September.

Check details about this test week event at https://fedoraproject.org/wiki/Test_Day:2023-09-05_I18N_Test_Day wiki page. You can submit your results on page https://testdays.fedoraproject.org/events/161

Fedora 39 : Issues in Fedora with PyGobject and sway-tests.

Today I wanted to test this repo named sway-tests.

I followed the steps there and received an error from gi.repository.

This error is related to another issue related to PyGobject.

In Fedora Linux distro, installing PyGobject is done with pip like this:

$ pip install PyGobject

In order to have no errors, the dnf or dnf5 tool should be used like this ...

I tested the functionality of this installation with a simple example:

import gi

gi.require_version("Gtk", "3.0")
from gi.repository import Gtk

win = Gtk.Window()
win.connect("destroy", Gtk.main_quit)
win.show_all()
Gtk.main()

It worked very well.

After solving this issue, I returned to the initial one and tested the sway-tests.

$ whereis sway
$ env/bin/pytest --sway=/usr/bin/sway
$ sudo env/bin/pytest --sway=/usr/bin/sway

I used the command both with and without sudo.

Both generated the same errors.

For the following command I had to install ... xorg-x11-server-Xephyr:

Xephyr is an X server which has been implemented as an ordinary X application. It runs in a window just like other X applications, but it is an X server ...

... the fixed centered black window specific to the xorg runtime appeared and somewhere on the side the terminal showed me a bunch of errors.

... obviously, I don't know how well sway-tests is implemented, now it's an archived repo, but I solved the use of PyGobject in python on the Fedora linux distribution.

Fedora 39 : testing Godot on Laptop and VirtualBox.

Today I watched a bit of the video series on the YouTube channel Fedora.

It's a whole team that maintains the Fedora packages and their development. I thought to check if I have the possibility to effectively use it in the development of software on Linux that has multiple functionalities. And because I currently work on Windows with Godot version 4.1.1 and C#, I took the first steps for installation and testing.

Let's install the Godot game engine tool on Fedora Distro Linux.

$ sudo su 
# dnf5 search godot
# dnf5 install godot.x86_64
# exit

Let's open and test with this command:

$ godot

The Godot interface comes with version 4.0.3 and is functional on my laptop with Fedora. Obviously, I have not tested all the implemented functionalities, but they seem to be good and ready to work.

On the other hand, testing on Virtualbox, it seems that it can't start the Godot interface.

It seems that Godot depends on OpenGL and needs some minimum requirements to work properly starting with OpenGL version 3.3.

Fedora 39 : How to start using cockpit tool in firefox.

Use lie any default installation like any Fedora Linux Distro package for cockpit tool with DNF or DNF5 tool.

$ sudo su
# dnf5 install cockpit
# systemctl enable --now cockpit.socket
# firewall-cmd --add-service=cockpit
# firewall-cmd --add-service=cockpit --permanent
# exit

The next step is to test if this runs well.

Get your ip address with netstat:

$ netstat nr

Because I used an virtual box for testing Fedora I get this ip 10.0.2.0

Use with firefox in the terminal:

$ firefox http://10.0.2.0:9090

The result will be the online cockpit tool.

News : An old change double equals is deprecated.

... although the change is old, for me it is new !

Fedora 39 : micro - terminal .

Let's see how works n Fedora 39 Linux Distro ...

Fedora 39 : Test Day:2023-08-11 Fedora 39 DNF 5

See more about this test with DNF5 on this wiki webpage and on this test results webpage.

Fedora 38 : Sway on VirtualBox.

Sway is a tiling Wayland compositor and a drop-in replacement for the i3 window manager for X11. It works with your existing i3 configuration and supports most of i3's features, plus a few extras.

You can find this desktop at this GitHub project.

The official webpage comes with a video tutorial on how to use it.

Installation is simple with these commands using the dnf tool:

# dnf group install sway-desktop-environment
# dnf install sway-config-fedora

It is possible to ask you for additional arguments for installation like this: --allowerasing or --skip-broken.

After installation, reboot and select sway from the desktop switcher

NOTE: The display for virtual video card from VirtualBox need to be set to Enable 3D Acceleration.

Let's see the result of this desktop environment ...

Fedora 38 : Openbox from GitHub.

I tried to use the OpenBox desktop environment in Fedora 38 and it seems to be incomplete, see also this thread.

I try to build the Openbox desktop from the source code, see the GitHub project.

$ git clone https://github.com/danakj/openbox.git
$ cd openbox

I need to install these: gettext-devel, glib2-devel, libtool, and pango-devel.X86_64 all devel libraries with dnf tool ...

Use the next commands, you will see some errors about some deprecated libraries and source code when you use the make command.

$ ./bootstrap
$ ./configure
$ make 

The go-to openbox folder to see the result:

$ cd openbox
$ ls -lFGC

The last step is to run the Openbox after you solve these:

Failed to open the display from the DISPLAY environment variable.

Openbox-Message: A window manager is already running on screen 0.

Because you are into environment area you need to close it.

After several attempts, I managed to pass these issues and ran the command:

$ ./xinit

This is the result is this:

I don't really have skills in this field of changes in Linux distributions and I wouldn't want to give wrong indications.
