NethServer Shows Black Screen on Boot/Web UI – How to Fix?

Hi everyone,

Iam experiencing a black screen issue with NethServer. When I try to boot the system, the screen goes black and does not load the login prompt or desktop environment. In some cases, the server seems to be running, but I can’t access anything on the screen. Additionally, when trying to access the NethServer web UI (Cockpit) the page loads but remains black, with no visible interface elements.

Here’s what I have tried so far:
Restarted the server multiple times.
Checked the web UI access from different browsers.
Verified network connectivity and firewall settings.
Looked for error messages in system logs var/log/messages,/var/log/cockpit/.

Could this be related to a failed update, a graphics driver issue, or a Cockpit web interface bug? Has anyone else encountered this, and how did you fix it?
Any help would be greatly appreciated! Thanks!

Hi and welcome in the world of nethserver. Are we talking about NS 7 or NS 8?
