libCEC connection errors - jojorabbit - 2024-11-17
Jellyfinmediaplayer linux client taking a long time to open, I looked into logs, and seems it is repeatedly trying to connect to libCEC and failing till it connects.

any idea on what the issue is, and what can i do to fix it.
- Jellyfin.Server 10.9.7.0 running in a docker container on rasp pi
- jellyfin-media-player 1.11.1-2 from AUR
- Arch/Hyprland
RE: libCEC connection errors - TheDreadPirate - 2024-11-17
I believe the issue is your use of Wayland/Hyprland. This user on github had a workaround that worked for them.
https://github.com/jellyfin/jellyfin-media-player/issues/610#issuecomment-2082020267
Install JMP via flatpak and disable the setting they mentioned.
RE: libCEC connection errors - jojorabbit - 2024-11-17
thanks, yea flatpak version launched instantly, even tho most of the issues in that thread seems to be related to nvidia gpu, and i have an amd igpu
didnt even need to disable that wayland socket thing
RE: libCEC connection errors - zjeffer - 2025-03-08
I'm having the same issue, on a new desktop with an AMD iGPU (9950x), also on Hyprland. I don't have any issues with black screens, just slow startup.
On my previous system (which had Nvidia) I could fix the black screen described in that github issue by launching with
--platform xcb.I'd rather not use flatpaks to fix this, perhaps it's an issue with AMD iGPUs?

Does your DE support xWayland? Jellyfin Media Player does not support Wayland yet so your DE needs some sort of X11 compatibility for JMP to work. Work is being done to make JMP work in Wayland, but that requires an almost entire re-write of the app.
RE: libCEC connection errors - zjeffer - 2025-03-14
Yes, Hyprland supports XWayland, and that's why I always run jellyfinmediaplayer with
--platform xcb. On my previous system (with an Nvidia card) this worked fine but not on my new desktop with an AMD iGPU.My new Nvidia GPU arrived yesterday, and now JellyfinMediaPlayer starts up quickly again, so the problem definitely lies with the AMD iGPU or its drivers.
I'm aware of the work being done to make JMP work in Wayland, I've actually contributed to the repo a little for that
Sadly development on that point is very slow, no-one seems to have a clear plan as to how to move to Qt6, as it indeed requires a pretty big rewrite. It's an increasingly big problem because Qt5 standard support has already ended in 2023...
RE: libCEC connection errors - sirbarkalot - 2025-10-21
I had this same thing happening and fixed it by disabling cec entirely. Since I run the player on a linux machine I don't think I need it for now:
To disable cec edit the file (linux) ~/.local/share/jellyfinmediaplayer/jellyfinmediaplayer.conf and set cec enable to false
...
"cec": {
"activatesource": true,
"enable": false <--- this
...
