Bug Description:


With the live ISO of Debian 13 Trixie Cinnamon, on my system (AMD 5950x + RTX 5070 Ti), the system boot but it's impossible to access a graphic session.


It displays an error message on startup :


nouveau 0000:00:00.0 unknown chipset (1b300a1)


After this I can use the text console. If I use the commande line "startx" the graphical environment then starts without problems.


If I edit Grub at boot and add the function "nouveau.modeset=0" like below, there is no change, it still does not work :


GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nouveau.modeset=0"


This affects all ISOs when you using Cinnamon.


Strangely this problem is only present under Cinanmon, everything works fine from Gnome.


I am attaching the files :


- boot.log


- Xorg.0.log


After installing Nvidia's proprietary .run driver, everything is back to normal.


Thank you to correct this as soon as possible.


Best regards.
