Note: I haven't enroll key in BIOS when installing Nvidia driver for the first time perhaps it was causing the sleeping bug? i really don't know, but the bug stopped after reinstallating the Nvidia driver and enroll the key in BIOS.
**IMPORTANT**: It seems i made a bug in the system which prevent nvidia- suspend.service, nvidia-hibernate.service, and nvidia-resume.service from working as i kept meddling with Nvidia settings. I am not expert so there could be more bugs i am unaware of. The bug seems to happen because the files of services aren't installed with driver for some reason. ============ Steps for reinstalling driver ============ 1) sudo apt update && sudo apt -y upgrade 2) removed Nvidia driver sudo apt --purge remove '*nvidia*' 3) install nvidia driver again. there is key something that should sudo ubuntu-drivers install 4) restart and on menu, blue colored menu located in the middle part of the screen in case of dell laptop, choose enroll the key. Note, Don't choose continue choice from menu before enroll the key. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1946303 Title: No video after wake from S3 due to Nvidia driver crash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-470/+bug/1946303/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
