A small glitch in 8.4.9?

Hi Folks;
I have 2 boxes running Nvidia cards in Linux Mint 22.1. On both systems, after any restart, both video cards are unrecognized. You can see it on the web control page by a square bracket around the card type, ie [GeForce RTX 4080] instead of the normal GeForce RTX 4080.A quick reinstall fixes the problem but I'm curious why it's happening at all. Does anyone have a fix for this? Thanks in advance.

This seems to be Mint Linux 22.1 issue. I have a test system with it and it behaves exactly the same.
For a moment resolution is to restart fah-client service upon the reboot. I know, this is stupid, but yeah...
sudo systemctl restart fah-client

It also happens on kubuntu 24.04 atleast to me.
I fixed it permanently by adding myself to the fah-client group; sudo usermod -a -G fah-client username then logged out and back in.
Then issued sudo fah-client let it launch sudo systemctl restart fah-client closed it and rebooted.
No more permission issues upon reboot.
Also did you do any of amd's perquisite's? you should do at minimum
Code: Select all
Grant GPU access to all users on the system
Create a new file /etc/udev/rules.d/70-amdgpu.rules with the following content:
KERNEL=="kfd", MODE="0666"
SUBSYSTEM=="drm", KERNEL=="renderD*", MODE="0666"
Reload the udev rules:
sudo udevadm control --reload-rules && sudo udevadm trigger
This configuration grants all users read and write access to AMD GPU resources, including the AMD Kernel-mode GPU Driver (KMD) and Direct Rendering Manager (DRM) devices.
per this

Nothing special for AMD, just what is outlined in my ultimate rocm guide
This issue was not present on mint 22.0, on the same pc
