Previously, I had an nVidia graphics card and had no problems. However, after updating the graphics card and drivers for the AMD card, my screen does not turn off after the specified time in the power manager.
For example, before, I had it set to turn off after 3 minutes. Now, I set any time and it turns off, then turns on (only on x11). That is, it should turn off and not turn on without mouse or keyboard movement, but it turns on immediately after the screen displays a message that there is no video signal.
I would prefer not to completely reinstall the system to test how it behaves on a clean installation of the system and AMD drivers. Therefore, perhaps you can suggest something. I have tried different kernels (5.15, 6.1, 6.2, 6.3), but there is no effect.
Also, since I installed the AMD card, I hoped that open source drivers would give smoother performance for the entire system. However, when working on Wayland, the screen also does not turn off at all. It only turns off on x11, but immediately turns on.
At the same time, my peripheral devices are working properly and I have not changed them. That is, the same mouse and keyboard were used with the nVidia card. I have no other devices that could be waking up the screen.
