I have one workstation with RTX4090 and Intel i7. Two monitors connected, one 2K and one 4K. Sometimes I hit black screen for two monitors. Have to shutdown the workstation through power key long press.
Which log can help understand this issue and what is your suggestion?
Please run nvidia-bug-report.sh as root and attach the resulting nvidia-bug-report.log.gz file to your post.
Does vidia-bug-report.sh works after a reboot? How can I do it when the screen is black.
BTW, I have to replace a new RTX4090 card.
If you have log persistence set, some errors should be caught in the logs even after reboot.
