I have a question about ubuntu 22.04. My desktop is 13600kf with Nvidia 4070 super graphics card. I installed ubuntu 22.04 on it. Now I found a problem, that is, my computer hangs. The specific phenomenon is that after I click suspend, the screen will turn off after a while, and the fan of the desktop computer will also stop rotating. I think it has entered the suspend state.
Unfortunately, when I click the desktop computer The power button wakes up, and the desktop fan and other devices start to work normally. The light on the monitor is also white (meaning there is information), but after a while it turns yellow (meaning there is no information). During this period, the screen does not change.
How can I troubleshoot or solve this problem? I will use Linux, but I have no idea how to solve this problem. I hope someone can help me. I would be grateful.
