-1 — this update makes it impossible to log in through cosmic-greeter on AMD hardware.
cosmic-comp 1.5.0 aborts during the greeter-to-session handover because the DRM node is still held by the outgoing greeter compositor:
Failed to obtain file descriptor for drm device: /dev/dri/card1 Caused by: Failed to open device: Device or resource busy (os error 16) Error occured in main(): Backend initialized without output
Result: black screen after entering credentials, greeter returns, session never starts.
Bisected on the same machine and same kernel: 1.4.0-1.fc44 logs in normally, 1.5.0-1.fc44 does not. Reproduced on two different kernels (7.1.3-cachyos1.fc44 and 7.1.5-201.fc44), so this is not kernel-related.
Upstream regression from pop-os/cosmic-comp PR #2382 (merged 2026-07-24). Also reported as upstream issue #2690 (Fedora 44, AMD) and #2680 (Arch, hybrid). My full bisection is posted upstream here: https://github.com/pop-os/cosmic-comp/issues/2690#issuecomment-5152356434 Fix proposed in PR #2670 — NOT MERGED as of 2026-08-01.
Hardware: HP ZBook Ultra G1a, AMD Ryzen AI Max+ PRO 395, Radeon 8060S (gfx1151), single integrated GPU, internal panel only (no dock, no external monitor).
Workaround:
sudo systemctl restart cosmic-greeterfrom a TTY, at every boot.Please consider either reverting to 1.4.0-1.fc44 for F44, or carrying PR #2670 as a downstream patch.
Updating my earlier comment on this update: the -1 I intended did not register — it went into the comment text instead of the karma field. Setting it properly here.
Since that comment, this regression has been confirmed on two further single-GPU AMD systems, in addition to mine:
This is therefore not limited to hybrid-GPU or multi-display configurations, and it reproduces across three different AMD platforms. One reporter observes it on 100% of reboots.
Upstream status as of 2026-08-02: the root cause is PR pop-os/cosmic-comp#2382 (merged 2026-07-24). The proposed fix, PR #2670, is NOT merged — a cosmic-comp maintainer has objected to the retry approach and would rather revert parts of #2382, and the PR author is away from the affected hardware for at least a week. Nothing has landed on master.
Given that timeline, please consider reverting cosmic-comp to 1.4.0-1.fc44 for F44 until an upstream fix exists. As shipped, affected users cannot reach a desktop session without a manual
systemctl restart cosmic-greeterfrom a TTY after every single boot.
