Hello, I’ve been referred here by Nvidia support because I’m currently running Ubuntu 18.04 LTS. The issue has been ongoing and occurred on both my previous RMAed card which emitted noxious fumes at 70C as well as the replacement which only has this black screen intermittently but consistently.
The problem is the screen will go black for roughly 1-2s and then pop back a few seconds later. During this time the monitor which is an AOC 4K monitor does not show a signal loss, this occurs intermittently 1-10 times a day.
I’ve performed a number of steps troubleshooting this and this only occurs with the HDMI port, there are no issues on the DP port. I’ve re-seated cable connectors on both sides to ensure this is not an intermittent physical connection issue. I’ve borrowed a second high quality HDMI cable and confirmed the issue remains.
My primary use for the card will be in running some basic ML research, but having the display drop gets annoying and shakes confidence as these can be signs of prematurely failing hardware. For the price of the card I’d like to get this working and would appreciate any help you can provide.
To start off, I’ve read the post about asking for help it suggests running Xwindows with logverbose 6, I’m having difficulty finding the procedure for doing this with Ubuntu 18.04 LTS.
The core gnome and xserver components and associated configurations are prepackaged within snap packages which I don’t know how to access or change, nor have I found much documentation on how to move forward to get the needed visibility to run your bug report script.
I’ve attempted changing snap packages like this in the past without much, really any success.
Best Regards, Nathan
