Dear @SivaRamaKrishnaNV
If the system is continuously on, you don’t see the issue?
No indeed, if the system remains on I don’t face any problem.
The issue happens on only reboot , but after a ~12 hrs .
If I flash and then reboot the system multiple times within a shorter time frame there is no problem for the Display manager.
Its only after an overnight period , if the Nvidia drive is power cycled , the display mangers get killed and configs are deleted.
