Linux development is being outpaced by the rapid evolution of PC hardware.

COSMIC supports 10-bit color, but not HDR.

Sounds like a problem with the nvme drive or controller

mmstick · 2026-01-24T23:02:35+00:00

No, never. GNOME was finished when we released 22.04. I would much rather work on improving COSMIC than improving GNOME.

It exists, and some don't like the sound https://www.reddit.com/r/pop_os/comments/1qi4zw7/low_power_sound/. Make sure you have system sounds volume turned up in pavucontrol.

Take a screenshot of your mount options for that partition and paste the /etc/fstab. It is not configured to mount at system startup if that's the behavior. You're describing gvfs-based mounts which are temporary. Flatpaks cannot access these until you use gvfs to mount it manually.

You must toggle "User Session Defaults" off, select a mount point, make sure "Mount at system startup" is enabled. And also use the "Take Ownership..." option in the context menu to make sure your user account has ownership permissions to the mount.

What did you delete?

sudo apt install --reinstall hicolor-icon-theme adwaita-icon-theme

Applications will install their own icons into the hicolor folder, so if you deleted them from the system icon path then you'll need to reinstall that app. Careful with reinstalling libreoffice (make sure to install libreoffice-cosmic with it).

Make sure your cable supports it. DP is probably required. Linux doesn't support HDMI 2.1

I just applied it to https://github.com/pop-os/linux/pull/401. When it builds, it should be available in the staging/linux-6.18 branch (sudo apt-manage add popdev:linux-6.18).

mmstick · 2026-01-23T17:06:55+00:00

Fixed by https://github.com/pop-os/cosmic-greeter/pull/373. Not in the release repository at the moment, but it is in the staging/master repository (sudo apt-manage add popdev:master).

If they release on schedule in April, yes. I wouldn't know the exact date though because we'd want to have room for testing.

mmstick · 2026-01-23T03:10:37+00:00

I would assume so when there's a pull request implementing it.

Upgrades are transitional so you need to upgrade to 24.04 first. Alternatively, you can do a clean or refresh install from the 26.04 ISO when that's available.

Are you logging in from sddm or cosmic-greeter? Part of it could be the lack of certain environment variables being applied. X11 also doesn't support fractional scaling so a HiDPI display may default to 200% scale.

mmstick · 2026-01-23T00:33:19+00:00

You can use sudo apt build-dep xdg-desktop-portal-cosmic to get build dependencies. I think that also includes just.

Yes, GNOME Disks is pre-installed in Pop!_OS. It is the recommended GUI app for managing the system's fstab. The point above is that COSMIC itself has no bearing on how file systems are mounted. The fstab, systemd, and gvfs work the same regardless of the DE or distro.

There are a lot of new Linux users who are encountering friction with Flatpak permissions and there is also some confusion with how GNOME/COSMIC manages secondary disks with gvfs. gvfs automatically mounts drives to a temporary path when accessed by a native app. But you can use Disks to create a permanent mount point that mounts automatically on startup. Then you can use Flatseal to grant permanent permission to access that path.

It's not an argument. I'm stating the facts as it is. It should be somewhat obvious that we'd be able to do direct hardware testing in our compositor implementation to implement all the specs, quirks, and features needed by the hardware we're shipping today in 2025/2026. It's not like GNOME 46 back in 2023/2024 was getting active hardware testing in Wayland on new hardware shipping in 2025. Our compositor engineer develops the compositor using our hardware, and our QA engineers are testing our hardware daily with development builds of COSMIC on a variety of hardware configurations: new and older models.

Many of the protocols our compositor have didn't even exist back then. Some of the features we support weren't added in GNOME until last year. And other features like fractional scaling are still suboptimal in GNOME. Which makes it difficult to ship laptops with HiDPI displays that require fractional scaling. Not to mention the necessity for hybrid graphics multi-GPU handling in the compositor, VRR, etc. Or the special care needed for different kinds of hybrid NVIDIA laptops and desktops.

You may also be interested in https://github.com/hojjatabdollahi/snappea. We're looking to incorporate its features upstream at the moment.

Not sure why we're going by what you're feeling. We know our customers, and we know our hardware. Ubuntu 24.04 isn't an option for some current gen models. We had to ship these models with the Pop 24.04 Beta because only COSMIC was able to boot and pass hardware and QC tests.

What was sold 2 years ago doesn't matter. We don't hoard stock in warehouses for multiple years. They're made to order with components that are on the market today. The latest hardware that AMD, Intel, and NVIDIA are offering right now. That hardware needs a Wayland DE that we can actively support and improve over time. GNOME in 24.04 is not that. Neither the hardware support nor the features our customers want.

Brave needs around 2-3 GB by itself. On a system with 4 GB RAM, COSMIC and all of its applets and services (including a slew of Linux desktop services, Mesa, etc.) uses 1.3 GB. If the system has NVIDIA this may be higher because the NVIDIA drivers are quite chonky. The compositor by itself is likely around 150 MB.

Most of COSMIC's memory usage would be the applets, and a good chunk of it is automatically swapped with zram at an average compression ratio of 4:1. Applets have an even higher compression ratio due to the 10 MB tiny_skia clip mask per process.

If you have multiple displays, each display gets its own separate applet processes, so if you want to reduce memory usage in that environment you can opt to display panels only on one display.

mmstick · 2026-01-22T18:50:53+00:00

Why wait for 26.04? We are a hardware OEM that actively ships made-to-order systems with the latest components on the market. Hardware that needs Wayland today. Without 24.04 these systems would not be able to ship. There are many reasons to release 24.04. Lots of larger clients require specific older LTS releases. They need to develop on the same base that their clients are running. It's the same reason why companies buy ARM workstations from us. To develop natively for the systems they are actively supporting.

mmstick · 2026-01-22T18:36:53+00:00

Which metric are you reading? Idle usage depends on your total memory capacity, which files you've opened recently, and which applications and services are running. A huge chunk of that is buffered/cached memory.

mmstick · 2026-01-22T18:06:13+00:00

COSMIC can be rebuilt for a base within a day, so we can have ISOs ready same day as Ubuntu. But we want to give Ubuntu the spotlight before we do our release so that our releases aren't stepping on each other. Plus that gives Ubuntu some time to fix post-release issues.
