I went out and bought a new 12th generation Intel box to do VirtualBox testing on and moved the nvme from my gen 10 5080 to the gen 12 5000.

It has the UHD 770 graphics processor but does not display video on the Monitor - the BIOS does and the grub menu displays fine.

I do have ssh and vnc into the box. I am able to use it but not on the unit itself.

Larry Finger helped me gen 6.4.0 kernel on the box to see if newer i915 drivers fix the problem - it did not.

It is running Leap 15.5 and has 8 VirtuaBox guests running - I did have to add ibt=off to get that to work.

Per the internet and Linux with gen 12 - it was reported that you needed this parameter on the kernel line - It made no difference.

GRUB_CMDLINE_LINUX_DEFAULT="noresume splash=verbose showoptsi915.force_probe=4680 ibt=off"
