I have a Logitech MX Master 3 mouse, connecting over Bluetooth. After upgrading to Fedora 41 with bluez-5.78, it takes about 5 seconds to reconnect and be usable after it goes to sleep for being idle. The mouse's LED lights up solid during that time. On a Fedora 39 test, it looks like this behavior started with bluez version 5.77 - 5.76 works fine. I saw version 5.79 in F41 updates-testing and tried that, but still get the same 5 second delay problem. I seem to remember a previous issue with bluez+MX Master 3. Current system is F41 x86_64, all current updates plus bluez 5.79 from updates-testing. Reproducible: Always
It's unlikely to be bluez Please include: * kernel version * linux-firmware version * bluez version * type of bluetooth controller (lsusb| grep -i blue) * the bluetooth devices (make and model) that you are trying to pair
Well, it reliably happens with bluez-5.77 (and newer) and not with bluez-5.76 on F39. It takes 30 minutes to test, I guess that's how long the mouse waits before going into a sleep mode. kernel-6.11.5-300.fc41.x86_64 linux-firmware-20241017-2.fc41.noarch bluez-5.79-1.fc41.x86_64 Bus 003 Device 002: ID 8087:0029 Intel Corp.

I was going to build 5.76 for F41, but saw there was already a build in koji, so I downgraded to bluez-5.76-2.fc41, and that works fine. No noticeable delay reconnecting after the mouse has been idle for a while
So I believe this has been fixed with the kernel-6.11.10-300.fc41 update
It seems to be fixed, yes. Using: kernel-6.11.10-300.fc41.x86_64 bluez-5.79-1.fc41.x86_64 Thanks
Actually, scratch that - if anything, it has gotten worse (takes even longer to re-sync after mouse idle). Maybe it's after a system suspend/resume cycle (so that's why I didn't see it immediately)?
Is this still an issue?
It doesn't seem to be happening all the time, but it still happens (sometimes taking 10+ seconds to start working again). That's with: kernel-6.13.9-200.fc41.x86_64 bluez-5.79-1.fc41.x86_64 Downgrading bluez packages to 5.76-2.fc41 makes it work again.
Can you test this with updates-testing https://bodhi.fedoraproject.org/updates/FEDORA-2025-99ba5bbe50
Gave it a try, unfortunately doesn't seem to fix it. It works okay after a boot (maybe slightly slower to come back after idle), but after a suspend/resume cycle and then letting the system sit for a while (hour or so), the mouse takes a long time to work. The Bluetooth tray icon (MATE desktop) turns green, so it's connected, but it won't work for 10+ seconds.
This is still an issue with: kernel-6.16.9-100.fc41.x86_64 bluez-5.84-2.fc41.x86_64
Upgraded to Fedora 43 and this is still an issue.
I think this is fixed in bluez-5.85-1.fc43
