Did you try only over the Icon in the Taskbar or did you go direct in settings?

[Lahdre]

Hi Duke187

I have tried both the taskbar and settings when I toggle the enable option it doesn’t do anything and the bluetooth icon does not appear on the taskbar either.

[Duke187]

[Duke187]

thank you very much for that informations.

i did beside some research about this Dogle but there not any good new for ya.

This Dongle looking like isnt working under Arch Linux based systems or other Distros because of Clones/Copys of same ID . There was a older kernel who worked to pair but the devices arent work either.

So may you can get a other BT dongle and test this one. I had a hama mini it worked but since my newer mainboard i dont need a Dongle.

Garuda is working right in this way my bad for you .

[Lahdre]

Duke187 Ah that’s a shame luckily I do have an old spare Realtek Dongle lying around do you think I should keep this dongle maybe until a new update or kernel version update is available or ? I recently bought it brand new from Aliexpress Official Ugreen Store I would prefer to keep it around because it does work in Windows 11 Barrot USB BT v5.4 but I do have a Realtek BT v5.0 dongle just as a spare.

[Duke187]

keep it we never now . may you can use for other windows pc or whatever. Yey Aliexpress says all lol (Clone or Copy). Yeah try the realtek it should work.

[Lahdre]

Sweet lol XD yeah I’ll keep it I’m in the process of moving over my steam games like Elden Ring and Sekiro I still have my Windows 11 install so it’s still going to take quite a while to migrate all the games over and their save files over to Garuda I also have Shadps4 I want give a go on Garuda at some point and play Bloodborne as well XD
