[Kernel-packages] [Bug 1905132] Re: no audio output dummy only
I've just found out that upgrade to the latest "groovy-proposed" fixed my issue (see the description in https://launchpad.net/ubuntu/+source/alsa-lib/1.2.3.2-1ubuntu3.1).

[Kernel-packages] [Bug 1872311] Re: Brightness hotkeys not working on Lenovo S740
I had similar issue with Lenovo Yoga Slim 7 AMD Ryzen 4700U, in Ubuntu 20.04.1. Solved by upgrade of kernel to latest upstream (5.8). Another solution for me was installation of AMDGPU proprietary drivers. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1872311 Title: Brightness hotkeys not working on Lenovo S740 Status in linux package in Ubuntu: Confirmed Bug description: Brightness hotkeys (Fn + F11 for decrease and Fn + F12 for increase) do not work on Ubuntu 20.04 and Lenovo S740 laptop. The brightness hotkeys did not work on 19.10 either. I followed the guide here: https://wiki.ubuntu.com/Hotkeys/Troubleshooting In "Step-by-step Troubleshooting", none of the steps (1-7) did produce any reaction to brightness change key combinations.
