VGA output corrupted.

[[email protected]]

Hello everyone, 

I am having an issue with my unraid server. For some reason the onboard VGA is outputting a corrupted signal. The monitor recognizes that there is an output but it only displays vertical green lines (see image). I have: 

Rebooted, changed the vga cable, added a vga to hdmi adapter to use the other port on the monitor, swapped monitors completelly. The server works fine and i have no issues in the UI when i access it via the network.

 

However, i wanted to change some bios settings and swap some hardware and i can't do that if i can not see the direct output of the server. Any help would be appreciated.

 

Server details:
Supermicro X9DRH-7TF , Version 1.02
American Megatrends Inc., Version 3.3
BIOS dated: Fri 13 Jul 2018 12:00:00 AM BST

 

Intel® Xeon® CPU E5-2620 v2 @ 2.10GHz

 

Memory: 128 GiB DDR3 Multi-bit ECCstorage-diagnostics-20230902-1701.zip

 

Thanks,

George

I assume you cannot even get to the BIOS? That would suggest a hardware issue with the GPU, does IPMI work?

buy some crap gpu card to use and post with that. 

This is what i use EVGA GEFORCE GT 730.

 

But I dont know if this will work because you may have to switch the output in the bios, which i am assuming you cannot get into because of the video output.  But it is worth a try if you have an extra gpu laying around.  You could also try to find a remote management at BIOS/UEFI level.

I have already installed a spare GPU that i have but yes my problem is i can't get into the bios and it is still grabbing the onboard first. I also connected the IPMI but i am not seeing a new IP lease in my rooter. So it could be off. I tried to find the IPMIView software tha supermicro provides that can do lookup on the network but the download button on their page (https://www.supermicro.com/en/support/resources/downloadcenter/smsdownload) does not work.

Small update, I did manage to download the IPMIView app. did a search on the network and it didn't find the server. I guess IPMI is turned off. At this point the only option would be a motherboard swap unless there is a way to force the system to switch from the onboard to the spare gpu without using the BIOS.

It seems there are a number of Jumpers on your motherboard.

You should check if they are on the appropriate position.

 

If that doesn't help, you might try to Clear CMOS ?

Thank you @ChatNoir that was a good idea. I disabled the VGA so it was forced to grab the spare GPU. Sad that i need to "lose" my m4000 for display duty but its better than not having output. Maybe now i can fix the IPMI and not need a gpu output.
