Public bug reported: [Steps to reproduce] 1. Install Jammy and dist-ugprade 2. systemctl suspend 3. press power button to resume
[Expect result] system resume smoothly [Actual result] display glitch (please see the attachment) For GDM, it needs at least https://gitlab.gnome.org/GNOME/gdm/-/merge_requests/171#note_1429657 to protect issue happens. For Mutter, a related patch is https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2341/diffs could cover if nvidia is secondary GPU. For nvidia-driver, u-d-c, we need to follow https://download.nvidia.com/XFree86/Linux-x86_64/510.54/README/powermanagement.html to setup the parameters after some checks. I appended the parameters: options nvidia NVreg_TemporaryFilePath=/run options nvidia NVreg_PreserveVideoMemoryAllocations=1 and then the problem solved.
