Hey guys,
Im a relatively new Linux user, so pardon the stupidity thats about to follow. I have an Asus gaming laptop on which I installed Debian 13/ testing. Everything worked well, until I tried installing new AMD drivers.
I followed this wiki article for the installation of the drivers. However after I ran the command
# apt-get install firmware-amd-graphics libgl1-mesa-dri libglx-mesa0 mesa-vulkan-drivers xserver-xorg-video-all
and rebooted my system, I was no longer able to access my Desktop (“unable to access Cinnamon session”).
The good news is I can still access the terminal via Ctrl & alt & f2. However I am not able to reinstall cinnamon because I dont have network access (I think).
I might be wrong but I think thats because before rebooting I ran a VPN with killswitch enabled, which is now blocking my network access, but I have no idea how to disable this from the terminal.
Could you help a noob out to repair his system?
I would hate to reinstall and lose all my data :(
If secureboot is enabled try disabling it. If disabling secureboot resolves the issue re-enable secureboot and add the dkms signing key with mokutil: https://wiki.debian.org/SecureBoot#Making_DKMS_modules_signing_by_DKMS_signing_key_usable_with_the_secure_boot
This has nothing to do with secureboot, as the system boots fine according to the explanation.
That doesn’t mean it is loading dynamic kernel modules, which also require enrolling a machine owner key.
