I have an Acer Aspire V 15 laptop(V3-574G-504Y). The problem is on a fresh install of Kubuntu I am not seeing any bluetooth adapters
. And therefore bluetooth is not working on my laptop. Please help.
I executed some info commands that I found on the internet and got this output. To me it looks like the ath10k driver is crashing on loading my bluetooth hardware. Is there any workaround for this?
