No programs open due some display issue

So I'm working on setting up my new system: and now disaster hits home big time.
Code: [Select]
(gimp:4506): Gtk-WARNING **: 22:11:54.884: Locale not supported by C library.
        Using the fallback 'C' locale.
No protocol specified
Cannot open display:

What has gone wrong here, because no programs wants to open..?!

(process:6264): Gtk-WARNING **: 22:41:54.002: Locale not supported by C library.
        Using the fallback 'C' locale.
No protocol specified
Unable to init server: Could not connect: Connection refused
ConcreteInkscapeApplication<T>::create_window: Should not be called!

Nothing in X starts. Can execute terminal apps tho. But not x-apps from the terminal.

I have exactly the same problem  :o

After the last system update, no program can be started.
The problem exists on both a KDE machine and an xfce machine.
The KDE machine at least still starts up to the desktop, the xfce machine only has a blinking cursor.

Does anyone have your idea which update can be the culprit?

Thanks in advance.

Greetings
Roberto

Hi,

On my XFCE desktop, with WiFi on, everything is ok



However, as it seems, based on your terminal output, you have to set the proper locales on your system

Code: [Select]
(process:6264): Gtk-WARNING **: 22:41:54.002: Locale not supported by C library.

I have just found out who the culprit is.

I use networkmanager and there was an update of this package.
After downgrade from version 1.30.0-1 to the previous version 1.28.1dev+16+gdaad4e2fee-1 everything works fine again.

I hope this information helps others.

I also use NetworkManager 1.30.0-1, w/o such issues.

Btw, keeping old releases, is not a good practice.

In any case, fix your locales, because this may breaks other things in the future.

So edit your /etc/locale.gen and uncomment your locales, and after saving the file, execute
Code: [Select]
sudo locale-gen

I followed the steps on one machine and edited /etc/locale.gen.
Code: [Select]
X220:[roberto]:~$ sudo nano /etc/locale.gen
[sudo] Passwort für roberto:
.
.
.
.

# Locales enabled by Calamares
en_US.UTF-8 UTF-8
de_DE.UTF-8 UTF-8

Then I ran sudo locale-gen
Code: [Select]
X220:[roberto]:~$ sudo locale-gen
Generating locales...
  en_US.UTF-8... done
  de_DE.UTF-8... done
Generation complete.
After that I removed the entry networkmanager from the line IgnorePKG in /etc/pacman.conf and I installed the version 1.30.0-1.

Unfortunately, after a reboot, the programs still do not start.

I found out something else.

When I connect my computer with the LAN cable and then boot, I can start the programs.
However, when I open the terminal, it doesn't just show my user, as it usually has been, but also a combination of numbers and letters.
Code: [Select]
2a0a-a543-ebb4-0-2c14-9838-9259-88e6:[roberto]:~$

After unplugging the cable, I have the issue again.

With the previous version there is the hostname:

Roberto,
Did you properly set hostname?
For me after update to me version of nm has nothing changed

Put here please "cat /etc/hosts"
