Does it work on NomadBSD?

[louies0623]

I am not using NomadBSD, but it is normal on ghost bsd.

[probonopd]

Please retry with the latest ISO build.

[louies0623]

No, the bug is still there.

[probonopd]

Please compare which drivers and kernel modules are loaded. I don't have this hardware so I can only improve if you can tell me what to change.

Also, we are using initgfx from NomadBSD, so it is always a good idea to also test there.

Thanks!

Where can I see drivers and kernel modules are loaded？

[louies0623]

I tried NomadBSD and it was very laggy, but the screen was normal. Supplement: There will be a short Grable screen.

[probonopd]

Please see https://hellosystem.github.io/docs/developer/graphics.html

cat /usr/local/etc/X11/xorg.conf.d/00-video-initgfx.conf shows which Xorg driver was selected by initgfx.

kldstat shows you the loaded kernel modules (please don't post all of them, just the GPU driver).

If you can submit a Hardware Probe from

• helloSystem
• GhostBSD
• NomadBSD

from the same machine, that will already help. It contains this information.

Ghost bsd 1 0xffffffff84c00000 db7e30 nvidia.ko 1 0xffffffff84aef000 e6dd0 nvidia-modeset.ko

Nomadbsd is more stable than Live after installation.

So what exactly do I need to change? I can only implement the change once you have confirmed on your machine that the suggested fix works.
