I have a device (convertible) that only supports S2idle and it works just fine with Ubuntu 23.04 if I configure properly its webcam, so I’d say it’s more a problem of if all hardware is supported than if the kernel supports it.

You may want to check if your device has any problems going to this website and searching for your actual model:

Maybe not too late, but System76 has a tool for OLED displays, I’m not sure it works with all displays but probably it worths a try:

I have limited experience with GPu pass through, but from what I’ve learned when I tried to do it with limited success (because of hardware limitations):

1. That reddish post is two years old, it’s ages ago regarding VFIO or GPU pass throug, look for for modern tutorials, preferably for the same hardware (GPU) or distro;
2. There’s no single way or “standard” of doing things, but if you mix parts of tutorials it may not work in the end, try to understand what’s done and apply to your setup;
3. Regarding hooks, test them with simple commands with some output first, so you can verify they are working as it should first, and try the VFIO related commands manually too so you are sure they do what you want;
4. From what I’ve seen, if the hardware supports VFIO/pass through then it will work usually after a few tries, if it doesn’t then there’s a big change you have some hardware limitation, many times related to a bad or broken BIOS/firmware.

Good luck!

Hello, there. I don’t think it is possible anymore using the stock installation/configuration (IIRIC old versions of Gnome did have a “session saving” option). If you use multiple workspaces, this extension is maintained by the official Gnome team, so it should still work for newer Gnome versions: https://extensions.gnome.org/extension/16/auto-move-windows/. If you don’t, take a look at Material Shell, it may do what you want.
