I’ve using Fedora 40 without any problems, almost for five months, until I upgraded to the 6.11.x Kernel version. If I use this Kernel, my screen won’t come back from suspension (the computer does come back), and sometimes I get some strange horizontal artifacts on screen, similar to an interference. If I turn the screen off/on, it goes away, but returns after a while.
If I use the 6.10.12, everything works great, so I’ll stay in this Kernel until this issue gets fixed.
Here go my specs:
MotherASRock X670E Steel Legend + AMD Ryzen 7 7700X + Corsair 64GB (2x32GB) 6200MHz CL32 Vengeance + Corsair RMx Shift 850W Plus Gold + Sapphire PULSE RX 7800 XT 16GB+Monitor Gigabyte M28U at 144Hz
Did anyone try the 6.11.5 kernel to see if this issue is still present?
UPDATE: Oh, I’ve just realized that John mentioned this exactly Kernel version in his last post, so it doesn’t work, so I won’t upgrade to Fedora 41 just yet.
I’ve read in another topic here in the forum that it might be Bluetooth related.
And that indeed seems to be my case. If I disable Bluetooth and then suspend the system, it wakes back just fine. But once I enable Bluetooth again, it doesn’t. Does disabling Bluetooth work for you?
Yeah, once I disabled Bluetooth, I was able to suspend and wake my computer up. I don’t know if the kernel maintainers are aware of that, but it might be worth reporting it
I was looking around to see if other distros were seeing this issue and found it reported on Arch too. I wanted to see if anyone was working on fixing this. The Arch post linked to this kernel bug report. Looks like it’s being discussed, but no fix yet:
