Question: Dump VBIOS option greyed out on Nvidia using latest 0.8.3 version (even in root mode with sudo)

[oscarbg]

Hi,
using lact 0.8.3 on Ubuntu 25.10..
seems fine:

even running in root mode:

sudo lact

seems Dump VBIOS mode is greyed out:

all other things seems OK..
noted also "OC/show historical curves" tab only shows data on root mode, expected?:

lact:

sudo lact:

I'm pretty new user to lact, so don't know if it's expected/documented and a fix possible to dump VBIOS of Nvidia GPUs using lact on Linux..

thanks..

Do you have the service enabled? With the service running, the UI should have access to everything even if it is not running as root itself. You should avoid running the UI as root (such as with sudo lact)

VBIOS dumping is not supported on Nvidia, it being grayed out is normal.

As for the graphs - after making sure the daemon is running, if they are still not showing, try pressing edit -> reset at the bottom of the graphs window.

If you are still having issues, please attach a debug snapshot.
