Can you please try 20.04 with kernel 4.15? How? I am not a Linux guru, only an expert system (both hardware and software) designer. Apparently the kernel coders made some assumptions about the hardware. I will continue to use 18.04 until one of the “updates” actually works.
P.S. I only recommend Ubuntu because Microsoft and Apple are so much worse! Robert Pearson On Fri, May 21, 2021 at 1:40 AM Kai-Heng Feng <[email protected]> wrote: > Is it a kernel regression?
