I’m having some trouble with suspend not working properly on my laptop, which has one of those Nvidia/Intel hybrid graphics systems. I run Debian 12 on it, with Gnome under Wayland.

Sometimes, my laptop will not go to sleep properly and just stay turned on. However, the screen will be black, and it won’t respond to anything. The only thing I can do in this situation is a hard reset.

I say sometimes, because most of the time it works correctly and I just can’t reproduce this bug. It might happen twice a day, but sometimes it won’t happen for a week. I have a feeling Nvidia is the culprit here, but I was wondering if anyone else ran into this and knows a bit more about what’s going on here?
