Hi. I have just installed KDE Fedora 40 today on my PC to dual-boot alongside Windows 11. While on Windows, I had no problem with sleep, on KDE Fedora, the PC freezes when I put it to sleep. The fans in the PC spin up a bit (not to maximum but the RPM audibly increases), RGP keeps on, but the PC is completely frozen. Keyboard, mouse and monitor go off. Pressing anything does nothing, including holding the power button for 20 seconds. I have to switch off the PSU, then switch it back on to make the PC work again. Can you please help me fix this?
PC Specs:
CPU: Ryzen 7 5800X
MB: Gigabyte B550 Aorus Elite V2 with the latest bios (updated to latest today, did not help)
