This one's sort of interesting. I was able to put the machine to sleep and get it to resume once, then I put it to sleep again, and encountered the same issue as before. So, you'll see the machine go into sleep _twice_ in this one, it just only logs the resume stuff once.
I did play with the NVreg_PreserveVideoMemoryAllocations parameter--my _prior_ log was with it set to 1, which seems necessary to get KDE Plasma to actually restore its desktop contents properly in a Wayland session--without this, it's just a total mess with missing icons and such. In _this_ log, I set it back to 0 to make sure that wasn't somehow impacting anything. I'm not sure whether my _one_ successful resume here was just luck, or what. ** Attachment added: "Another previous boot log" https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-580/+bug/2124978/+attachment/5910013/+files/prevboot.txt -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to nvidia-graphics-drivers-580 in Ubuntu. https://bugs.launchpad.net/bugs/2124978 Title: Graphics driver (Nvidia) does not resume from suspend Status in nvidia-graphics-drivers-580 package in Ubuntu: Incomplete Bug description: I am using an Nvidia RTX 4090, and I have an ASUS VG28UQL1A monitor, which I use with adaptive sync enabled. I am running Kubuntu 25.04. Ever since updating to graphics driver version 580, I have not had good luck getting the machine to resume from suspend. It just hangs indefinitely and never wakes the monitor. It seems to be unresponsive to any keyboard inputs (I have some configured that try to use KScreenDoctor to change displays), so I end up pressing the reset button on my machine, which seems less than ideal.
