If I upgrade from 387.12 to 387.22, or try 384.98, I can see my initial kernel messages, but then lose both displays directly after that. I can’t get anything on either X or VT. I’ve switched to using 381.22 because that version came up when I searched for NVS 315 drivers, and it works fine, but I’m not sure how to debug the issue with the newer drivers. I don’t see any errors in dmesg. All I really see there is logs about mode setting and audio. Any advice?
Please put
Option “ModeDebug” “true”
in the device section of /etc/X11/xorg.conf. You put it in the nvidia outputclass which has only effect if there’s no xorg.conf. Then run nvidia-bug-report.sh again.
