I managed to log back in with SDDM, but its now missing entries in Control Center

[Jonas Gamao (yamiyukisenpai)]

I can't change the wallpaper, nor the network config is in there.

In addition, the stuff in `/etc/xdg/autostart` isn't starting up automatically.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

For close to two weeks now, I haven’t been able to log into Unity on Noble (Intel CPU + Nvidia GPU). Then when the xz-utils situation started I stopped daily updating a second computer (AMD CPU+GPU).

Two days ago, I thought that the packages had been rebuilt, so I updated the second PC, now that one too loops from LightDM back to LightDM. I tried the usual fixes to no avail.

Lastly, a friend contacted me and he also experiences the same problem on his Ubuntu Unity Noble (Intel CPU + AMD GPU).

For now, I access my two PCs through the Cinnamon desktop and that works.

The problem remains as of 2024-04-08.

> For now, I access my two PCs through the Cinnamon desktop and that works.

Were you using Slick Greeter or Unity Greeter?

[Jonas Gamao (yamiyukisenpai)]

I'm not sure how to report this, but I noticed that the USB ports are malfunctioning every other reboot.

My USB WiFi adapter (TP-Link T3U Plus) stops working, and when I unplug, it doesn't show up. Same goes for my Logitech Unifying receiver.

[Jonas Gamao (yamiyukisenpai)]

I tried to do `ubuntu-bug linux`, but I got:

*** Problem in linux-image-6.8.0-11-generic

The problem cannot be reported:

This does not seem to be an official Ubuntu package. Please retry after updating the indexes of available packages, if that does not work then remove related third party packages and try again.

[AO (aofrl10n)]

Hi Jonas. I believe the Unity greeter is used by default.

Enabled proposed and updated unity-session, and that fixed it

[AO (aofrl10n)]

Thanks Jonas. I’ll wait for the packages to migrate out of proposed to test.

[AO (aofrl10n)]

After today’s updates of unity-session, gnome-session, I still can’t load Unity. From lightDM, I get stuck on the background. Tried unity-tweak-tool --reset to no avail. So as far as I’m concerned, this is not solved.

[AO (aofrl10n)]

Even after applying all the latest updates, I never was able to launch Unity. I decided to reinstall the system from the latest daily built, and everything is working.

Tested out a VM with NVIDIA GPU (passthrough) and the panels won't load. After a while it kicks out to LightDM

[Jonas Gamao (yamiyukisenpai)]

Reinstalled ubuntu-unity-desktop and unity-session

Turns out nemo was uninstalled in the process. shouldn't it be a dependency for unity-session?

[Jonas Gamao (yamiyukisenpai)]

I meant "nemo was uninstalled along the way"
