WIth new i7-12700T no video after grub.
Last modified: 2023-07-12 11:43:49 UTC
Full dmesg is here https://paste.opensuse.org/pastes/de340d9e1d9d 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. Both are Dell Optiplex Micro - they only have 2 Display Ports. 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.

I got the latest Tumbleweed and it does work with no additional kernel parameters. So I will use Tumbleweed on Box 2 and 3 - still need 15.5 on box 1 for VirtualBox testing.
I stand corrected on Tumbleweed has video the clone of the working one does not. They are supposed to the same hardware levels and BIOS is the same and the options appear to be the same LLR4 works LLR5 has no video but ssh and vnc work. dmesg from both: https://paste.opensuse.org/pastes/e7134f51ec2a https://paste.opensuse.org/pastes/0087987d171d I see an x.509 on llr4 that did not load on llr5.
Created attachment 867799 [details] Dmesg from good i7-12700T This is the good Tumbleweed Dmesg
Created attachment 867800 [details] Dmesg from no video i7-12700T This is good on BIOS and Grub but once Linux loads - Blank video.
Created attachment 867801 [details] inxi from llr4
Created attachment 867802 [details] inxi from Leap llr2
Created attachment 867803 [details] inxi llr5 - no video after grub
I discovered that the reason for no video was defective display port to hdmi cables. While think on how video is done - I wondered if the read the monitor was failing and I swapped the cable between llr4 and llr5 and the video moved with the cable. So I opened 2 new dp to hdmi cables and used them - all video now work.
Please close as this was a hardware issue and not an i915 driver issue. My older hardware had hdmi ports so I did not need DP to HDMI. Sorry - Looking at the internet on gen 11 and gen 12 issue made me think it was software and not hardware. Sleeping on it - While updating this with attachments - it dawned on me to see why llr4 worked and llr5 did not as their build date are the same. Problem moved.
OK, let's close.
