Dear nvidia team:
The DP monitor fails to light up after completing a long-term stress test on our custom carrier board, although the system is still accessible via the serial console (UART).The log files are attached
log.txt (459.9 KB)
What does that mean “The DP monitor fails to light up after completing a long-term stress test on our custom carrier board”?
So the monitor was able to work before stress test?
Sorry, let me clarify:
The screen won’t light up after I used GParted tool to repartition. It worked fine after the first flashing.So, is this issue related to my use of GParted for partitioning? How could partitioning cause the display to fail while the Serial Console (UART) remains functional and allows login?
What is the status of your /var/log/Xorg.0.log? Is this log still got refreshed after your every reboot ?
It is possible that Xorg not able to work anymore and make you think the display is dead.
Display is also layer by layer from kernel to userspace driver. Your kernel might be still fine but user space tools might not work there.
I will pay closer attention to the /var/log/Xorg.0.log and check if it’s being refreshed properly after a reboot.why would a standard partitioning operation via GParted lead to such a critical failure in the display stack?
Just to clarify. No one ever knows what is going on on your side.
Check what I said first to identify what is wrong first.
