Dear @balakrishnan.ayyanar,
Please check if Display manager gets destroyed after reboot is related?

Dear @balakrishnan.ayyanar,
The issue in the shared post is, the system gets updated automatically and noticed display after reboot.
Please check disabling auto updates(select never in check auto updates) as given in Display manager gets destroyed after reboot - #10 by anil-kumar.chavali

Thanks . it solved problem. I have to reflash it and do steps mentioned above.
I have concern that if some other software installation required to run (sudo apt-get upgrade ) then it could be an issue.

Other question have is after flashing os (from 5.1.6 to 5.2.6) I could not found the storage space which was there in /ota/pkg_data/ in 5.1.6 . it was around 100GB before but could not found that location in new OS . Sorry this was not related to above post . if needed will create new topic

Thanks,
Bala

Even after setting the automatic upgrade stopped , this issue came again . under /etc/gdm3 is deleted automatically. Why this issue coming up in 5.2.6(recommended by NVIDIA). if we go back to older OS(5.1.6) can we avoid this issues or it is problem of re flashing ?

Dear @balakrishnan.ayyanar ,
We did not notice display issues on DRIVE SW 10 release. But it has DRIVE OS 5.1.6 and DW 2.2.
You may check flashing DRIVE OS 5.2.0 + DW 3.5 release as well.

First we moved to the version 5.2.6 to avoid this issue mentioned here

We developed the ROS driver for sensors again for 5.2.6( Since drive work SDK is different from 5.1.6) and butwe face issue with HDMI port and the other ports in 5.2.6 .

then we give up the idea of using cupy and try to go back to 5.1.6 , if we use 5.2.0 again we have to check cupy and develop the ROS drivers .
