Upgrade issue + Nvidia = black screen white cursor

kusk0r

I have been enjoying the occasional Ghost BSD 24 session (Intel 14900K+RTX 4090) until I upgraded to an RTX 5090. I could then boot into GhostBSD but getting a black screen+white cursor. I tried forcing the update to ver 25 via a tty and it reinstalls all packages but still GhostBSD-version shows 24. Kernel shows same version as v24, I think 1400501 while I think it should be 1402000.
I installed nvidia drivers, linux libs, via the tty, following the instructions in the wiki and added the required lines to rc.conf. During boot it says
"KLD nvidia-modeset.ko depends on kernel, not available or version mismatch"
"linker_load_file: /boot/modules/nvidia-modeset.ko - unsupported file type"

As it is probably obvious i have minimal BSD experience. Running mainly Windows and part-time linux but also occasionally boot into GhostBSD and FreeBSD.

It seems to me like the kernel and kernel moduls are not the same version. I tried a clean install through the live iso via Ventoi but I have to select a legacy video driver and after installation i still get black screen - white cursor, no screens found. I then restored back the same partition with ver 24, tried update -f / upgrade -f again with (as expected version missmatch ) then reinstall proceeds but leads to the same result. I also tried to change to the unstable repo, force install again, same result. Tried loading the nvidia modules through loader.conf but same result.

I do have a working FreeBSD install with Plasma on X11.
I am booting GhostBSD via UEFI, does that boot process somehow still use the old kernel? Any other suggestions?

Create a full backup of your user data, perform a fresh installation of GhostBSD 25 using the latest ISO, and restore your data after the installation is complete.

Hello and thank you for your reply. Leaving some feedback if somebody has a similar issue.
After trying all sorts of solutions to fix my current system I backed up my data and installed GhostBSD 25 through the live media. Xconfig in the live iso did want so start X with the nvidia driver and I was prompted to choose a driver. NVIDIA driver was not on that list and the only on that worked was the scfb driver. If I cancel there and do xconfig from the prompt I get the choice to choose NVIDIA but then I cannot startX.
After getting to the livecd desktop with the scfb driver my network card was not enabled and I had to tinker a little to get it working (can probably do that after the install but I had multiple previous installs not working after installing without network). After the install I could boot into the desktop, update packages (which froze the desktop) but then after reboot all was working. I could then install NVIDIA drivers according to the wiki and everything i working now, my second monitor was auto detected. Small detail I noticed in the NVIDIA driver install is this time the name och the driver package shown during the install had .140200 at the end corresponding to the right kernel.
After install I did
sysrc -f /etc/rc.conf kldload_nvidia="nvidia-modeset"
then
nvidia-xconfig, also added
hw.nvidia.registry.EnableGpuFirmware=1 to /boot/loader.conf as it was suggested by the message after the install of the driver (maybe not neccessary)

Thanx for your help. It's always fun to try to fix a hard issue but sometimes you just have to go with the clean install.
