Fedora 39 : GNOME new version 44.2 .

Fedora 32 : Can be better? part 013.
I would say that I always have a problem with accessing the knowledge base related to errors, errors and configurations in Linux and Fedora distro.
I think it would be very necessary to have as up-to-date documentation as possible in the Fedora distribution system and possibly a database based on questions and answers.
That makes me think of the pilots' manuals ... where all the possible problems are listed.
It would be useful for anyone and especially saves users' memory.
In the age of artificial intelligence, a flow chart for each possible problem generated by Xorg, Network, services that indicate the areas of interaction and possibly the basic checks that a user should make, possible settings depending on the problem or the desired change would be a fantastic map for both a beginner and an advanced user.
After doing some SELinux configurations, my browser did not want to access the internet.
Until the deactivation, the number of SELinux alerts increased dramatically.
The written SELinux policies were not exactly correct.
Obviously I tried to fix the problem by disabling SELinux.
The ping utility sent and received packets to the internet, my browser does not connect to it.
Sometimes a symbolic link or incorrect setting can block your internet access.
I think the problem was generated when disabling SELinux by restarting and shutting down a useful service.
ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
Although attention was paid to the possibility of incorrect SELinux settings, a simple check and a restart of the systemd-resolved.service service solved the problem.
[root@desk mythcat]# systemctl status systemd-resolved.service
● systemd-resolved.service - Network Name Resolution

GNOME Developer Experience Hackfest 2013
This week Red Hat and the GNOME Foundation giving you the chance to attend the Developer Experience hackfest in Brussels.
The goal of the hackfest is to improve the overall application developer experience.
There are three main areas of work we suggest for this hackfest:
- Tooling (Anjuta, Monodevelop, application bundling, intltool, gtk-doc, autofoo and friends...)
- Developer docs and mindshare (unified online/offline API reference UI, app developer community building...)
- Further platform needs (improvement of data-driven apps and other needs with an unclear answer)
- Application bundling and sandboxing, the application as the first class concept in the kernel

Fighting Blender, NVIDIA and GNOME ...
Since I did pre-update and put Fedora 15, the system worked well until today.
Today I tried to relax a bit with Blender 3D, but ...
[free-tutorials@user ~]$blender
Info: Config directory with "startup.blend" file not found.
Segmentation fault (core dumped)
How to prevent uploading that file? Simply using:[free-tutorials@user ~]$blender --factory-startup
Segmentation fault (core dumped)
Obviously, I should try to debug:[free-tutorials@user ~]$blender --factory-startup -d
Blender 2.57 (sub 0)
Build: 2011-04-27 16:56:56 Linux:32bit Release
argv[0] = blender
argv[1] = --factory-startup
argv[2] = -d
read file
Version 256 sub 6 svn r36063
ordered
OBCube
OBLamp
OBCamera
Segmentation fault (core dumped)
Simply don't want, it's something related to graphics card ...[free-tutorials@user ~]$blender --factory-startup -d -noglsl
Blender 2.57 (sub 0)
Build: 2011-04-27 16:56:56 Linux:32bit Release

argv[3] = -noglsl
read file

OBLamp
OBCamera
Segmentation fault (core dumped)
So the problem is not related to GLSL.Then I tried to see what glxinfo says.
[free-tutorials@user ~]$glxinfo | grep Error
Error: glXCreateContext failed
I found this problem and I added to xorg.conf the following lines of code.Section "Files"
ModulePath "/usr/lib/xorg/modules/extensions/nvidia"
ModulePath "/usr/lib/xorg/modules/drivers"
ModulePath "/usr/lib/xorg/modules"
EndSection
I must admit that after restarting the computer, greeted me with the gnome interface and unprecedented special effects.Then I waited ... and waited ... I fixed up with a simple line of code:
$ gsettings set org.gnome.desktop.session session-name 'gnome-fallback'
... written in Xfce terminal, because in gnome I have not succeeded.Now I have the old gnome, slightly improved but it works flawlessly with Blender 3D...
