Fedora 42 / Gnome 48 (official release - non-beta): No HDR or Battery Health options

Ask Fedora

Good evening!

Earlier today, I upgraded from Fedora 41 Workstation (Gnome 47.5) to Fedora 42 (Gnome 48) via CLI. Typically, I upgrade via GUI, but for whatever reason it wasn’t populating as an option in Software Center and by midday, after refreshing countless times (including running “sudo dnf update” and “sudo dnf upgrade --refresh” more than once) I had lost patience and took the CLI route. :slight_smile:

As best I can tell, the upgrade went fine. Fastfetch (attached) shows that I’m indeed in F42, as well as G48, and even confirms that I’m in a Wayland session. The new font and minimal UI tweaks are pleasant and I enjoy them. For something that’s 99% the same as before, that 1% difference makes it feel new and fresh…

…however…

…the two new features which I was the most excited to receive were the options to enable HDR, and to enable “Battery Health” (by way of limiting battery charge to 80%). And yet, after the upgrade NEITHER one of them are available! I know to look for the HDR toggle under display…but it’s not there. I also know to look for Battery Health under power (or a submenu thereof)…but once again, not there.

This information is also included in the included screen capture of fastfetch, but if it’s useful to know, this is a 2023 model Asus ROG Zephyrus G14 gaming laptop, which is usually used hooked to a dock in a “desktop computer” context.

Naturally, I did a lot of Googling before I created this post, and the only thing I could find was on the Arch wiki, referring to the need to install a certain git which is available via the AUR in order to enable HDR (“vk-hdr-layer-kwin6-git” - I’ve also included a screenshot of this). But with this being Fedora and that being Arch, I didn’t know if that would apply to me, and so I have not yet installed the git. Moreover, this would not do anything to resolve the battery health issue.

In any case, any help would be greatly appreciated! I would love to be able to avail myself of these exciting new features!

Cheers!

UPDATE: When I hooked the laptop up to a different monitor - one known to support HDR, the HDR option appeared. So that appears to be functional after all. I had thought my laptop’s default monitor also supported HDR, but that is apparently not the case based on the option not appearing for it. Apparently, it’s not a matter of the option being “grayed out” on unsupported devices, but of being “absent all together”. Good to know!

However, since the colors are still slightly more vibrant with HDR off on both the computer and the monitor, I’m not sure I’ll avail myself of it, not unless or until there’s an option to oversaturate the colors in HDR, that is. :slight_smile: But even so, it’s a resolved matter now.

The battery health option still not showing is a little disappointing, but I appear to have this resolved now as well by way of a workaround: I’ve simply enabled the “Battery Health Charing” extension from the Shell extension website, and it appears to be working as intended…

…so ultimately, I think I’m good here, folks! Cheers! :smiley:

I don’t know, HDR works on Windows and any KDE Plasma, but not on GNOME 48.

For the battery health option, same here, I don’t have it.
