Gestern Updates beim Notebook installiert. Heute morgen dann kein #gdm mehr auf dem Notebook und direkt in die #console gebootet. Konnte dann in der Log-Datei sehen, dass gestern das #gdm3 Paket deinstalliert wurde. Ist mir irgendwie nicht aufgefallen. Aber warum? Auf dem Notebook läuft #debian #testing. Hab dann das Paket neu installiert und es gibt wieder eine grafische Anmeldung. Seltsam....
Upgrade #Ubuntu 24.04 to 26.04 went well. Some solvable issues, like Gnome shell extensions that needed an upgrade, and removing the Firefox snap. Only real issue is the low resolution during boot and on the login screen. Resolution is fine when starting a Gnome session. Is this a #GDM3 or a #Grub issue?

Is there no way to show a script-generated welcome message on gdm/GNOME? 🤔

I had an security idea where the welcome message would be a sha512 hash, created with todays date + time (15 minutes interval) + pre randomly created static salt.

When you are about to login you check the hash against a hash you created on your phone.
If it's the same hash, you know it's your computer and not a honeypot someone put there to get your password. 🔑

#ubuntu #gdm3 with multiple .desktop files in my /etc/share/xsessions, I still do not see the gear icon on gdm login screen. I cannot change from x11 to wayland. What am I missing? #gdm #gnome #wayland #x11

🇬🇧 New post on my blog: How to set a default graphical session in #GDM3

https://wazablog.fr/posts/gdm-default-session

Set GDM Default session (not the last used)

Some context: I own a Starlite V, and I use it as a hybrid PC with Gnome and Regolith Desktop. When I work at my desk, I use Regolith, then I turn off the computer and go away from keyboard. Then on the next use, I am on my couch and I boot in tablet mode, then GDM3 by default will send me back to the last session used (Regolith here), and… Bam!

#TIL: Wenn der #VNC (hier #tigervnc) nur ein schwarzes Bild zeigt: #Autologin von #gdm3 deaktivieren, auch wenn diverse Tipps gegenteiliges behaupten.

After moving to #KDE #Plasma from #GNOME on #PopOS / #Pop_OS...
When I unlock, I'm challenged for my password two or three times.
Still using #gdm3.

Ideas?

First response: "Place your right finger on the fingerprint reader." (I'm using a password.)
Second response: "Unlocking failed."

The only things I see in the logs that look relevant:

3/20/24 7:13 PM [email protected] secret_password_lookup_sync() failed: The name is not activatable
3/20/24 7:14 PM bihon kcheckpass[383187] pam_ecryptfs: seteuid error

MORE INFO:
The first prompt appears to only accept a password. The second prompt can accept a fingerprint OR a password.

I've already run
sudo apt purge gnome-screensaver

per https://support.system76.com/articles/desktop-environment/

but it isn't clear it helped.

A colleague helped me to extend the #gdm3 login selections. I now select #xsession and can use #nix home-manager for even more options. E.g. keyboard, language, global env variables, etc.
