🖥️ GNOME (versiuni de mentenanță / actualizări de securitate): Corecții critice pentru GDM și gestionare îmbunătățită a monitoarelor!

Actualizările punctuale (point releases) din seria GNOME aduc îmbunătățiri majore pe partea de securitate la nivelul managerului de autentificare (GDM), rezolvând totodată probleme legate de scalarea monitoarelor și gestionarea sesiunilor grafice pe Wayland și X11.

✨ Noutăți și îmbunătățiri principale:

🔒 Corecții de securitate în GDM (GNOME Display Manager):
• Rezolvă vulnerabilități legate de gestionarea sesiunilor de utilizator și autentificare, prevenind posibile escaladări de privilegii sau blocaje la comutarea între conturi.

🖥️ Gestionare mai bună a afișajului și monitoarelor (Mutter / GNOME Shell):
• Optimizări pentru configurațiile multi-monitor: remedierea artefactelor vizuale, stabilizarea ratei de împrospătare (refresh rate) și gestionarea mai precisă a scalării fracționare (fractional scaling).

⚡ Stabilitate crescută pe Wayland:
• Corecții de cod pentru prevenirea crash-urilor neașteptate ale managerului de ferestre Mutter în timpul schimbării rezoluției sau la conectarea/deconectarea monitoarelor externe (e.g. prin HDMI/DisplayPort sau dock-uri USB-C).

⚙️ Ajustări în GNOME Settings & Control Center:
• Rafinări la nivelul panoului de setări ale sistemului pentru o configurare mai fluidă a rețelei, Bluetooth-ului și economisirii de energie.

O actualizare recomandată tuturor utilizatorilor de distribuții bazate pe GNOME (Ubuntu, Fedora, Arch Linux) pentru a menține sistemul sigur și stabil! 🚀

#gdm hates me today
any clues on how to fix?
I reinstalled gdm, gnome-session, the desktop package.
ran `dpkg-reconfigure gdm3`
still nothing.
This is on the #mntreform
#debian unstable being unstable

FYI: If you used `gdmflexiserver` to launch a new session from something like `sway`, *this no longer exists upstream*.

Remedy: I switched to `lightdm`, which has `dm-tool` (which lets you switch to the greeter).

@fabiscafe To the room? It should be #gdm:gnome.org

… x11/gnome on FreeBSD in VirtualBox: GNOME Display Manager works only with GNOME Classic – not with GNOME – and a locked screen cannot be unlocked …

<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294977#c2>

＂This bug will be never fixed!

It requires lots of work (I mean complex) in x11/gnome-session, x11-wm/mutter, x11/gdm and x11/gnome-shell. These 3 ports are interdependant. They communicate each other through D-Bus.

In addition, gnome-session is becoming increasingly dependent of systemd (for start/stop services, applications and even autostart).＂

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. 🔑

No progress at all on this #Ubuntu #GDM login failure issue; I can now only use the machine with a PTS console login, then run gnome-session --wayland, and that gives me only basic function, no access to things like User Accounts.

journalctl only gives these two clues, neither of which yields any meaningful Search results (in 2026)

gdm-autologin][]: gkr-pam: no password is available for user
gdm-autologin][]: pam_unix(gdm-autologin:session): session opened for user guest(uid=1005) by guest(uid=0)
gdm-autologin][]: gkr-pam: couldn't unlock the login keyring.
gdm3[841002]: Gdm: GdmDisplay: Session never registered, failing

but console login proves the user has a perfectly good password! GDM3 fails on the auto-login acct, presents the list of users, clicking one lets you enter pw, then bounces back to the acct list screen and any subsequent attempts are shown a non-functional box to enter their pw and a 'back' button that does nothing. 😩

#gnome and #niri ... best of both worlds.

#gdm for looking, #niri as wm and all the good #gnome apps. even gnome-settings for managing network, bluetooth, sound.... :) love it

thanks to the #arch wiki: #GDM now great in 4k and with green accent

https://wiki.archlinux.org/title/GDM

...works with opensuse

anyone with #opensuse ... how do I scale up #gdm to 200% and change the accent color?

Hey #freebsd people. I have installed FreeBSD 15 on my Dell XPS 9500 which was very easy! However I am having an issue with #gnome the machine boots perfectly fine to #gdm login screen and I can type my password. As soon as I hit enter the machine freezes. I cannot even change to a TTY. Any ideas for how to debug it or what might be the cause? Pretty difficult when I cannot go to TTY

Trying from terminal I could see my home dir was owned by root which was part of the problem but not solved

Today, for the first time since I switched to Linux over 5 years ago, my #archlinux Z16 #thinkpad kept freezing after #gdm authentication. 😲

Apparently, because the status of `/run/user/1000` became corrupt. 🤔

1. TTY login
2. `loginctl terminate-user $USER` (cleanup sessions)
3. `systemctl restart systemd-logind` (recreating the directory)
4. `systemctl reboot`
5. Everything was back to normal

Took me an hour to figure out, though. 🫣

Ich habe auf meinem #Linux Desktop Rechner mal ein wenig mit den Displaymanagern rumgespielt.
Hintergrund: Ich habe ursprünglich den #Fedora #Cinnamon Spin installiert. Inzwischen nutze ich aber nur noch KDE. Da #Cinnamon den #LightDM als Desktopmanager hat und KDE als Standard eigentlich den #sddm dachte ich mir ich wechsle um es konsistent zu haben.
sddm fand ich gruselig. Habe dann #gdm probiert. Noch schlimmer.
Ich bin jetzt zurück auf LightDM und bleibe dabei. sddm und gdm werden gelöscht

Help need with #gdm in #opensuse tumbleweed.

I want to change the accent color in gdm.

machinectl shell gdm@ $(which gsettings) set org.gnome.desktop.interface accent-color "green"

is not working

When running #gnome via #jet #kvm I cannot see the #login screen after #boot. The login screen seems to not be visible by #hdmi so #kvm control is absent. #gdm Any ideas how to tweak this in #nixos ?
