Hi,
I’ve recently switched from Linux Mint to Fedora KDE because I enjoyed the experience a lot more and HDR is supported in Fedora KDE. However, since switching, I’ve been having problems during boot. (For quick reference, I fully formatted the SSD Linux Mint was on through the Fedora KDE installation, and then installed.)
After selecting which version of the system I want to use in GRUB (which is showing 4 Fedora KDE installs now.. a rescue version, 6.17.1, 6.17.12, and now 6.18.3) the system will randomly decide when to reboot. This either happens directly as a result of the GRUB selected version, when the system shows me the KDE login screen or when I have succesfully logged into Fedora KDE 43. This behaviour also occurs when the pc has to boot from hibernate. However, I am able to put the system into suspend and then immediately boot after. Only when the suspend is moved into hibernation, does the same problem occur.
Below is system info through fastfetch.
The only errors I can see are the following:
Jan 11 23:31:38 fedora kernel: ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20250807/psobject-2>
Jan 11 23:31:38 fedora kernel: ACPI BIOS Error (bug): Failure creating named object [\_SB.PCI0.GPP2._PRW], AE>

Jan 11 23:31:38 fedora kernel: ACPI Error: AE_ALREADY_EXISTS, During name lookup/catalog (20250807/psobject-2>
However, these are also shown in a succesful boot.
Quick edit: the shown kernel version is 6.17.1. This was currently the one that successfully booted. I was using 6.18.3 earlier today.
Secondary Edit: I changed HDR to off. This has fixed the problem.
