I tried the 5.8 kernel with Ubuntu 20.04 and after the boot the desktop is not seen ... this with Nvidia gtx 760 and nouveau driver ... unlike what happened with the 5.6 and 5.7 kernels in which the desktop loaded but not there was no hdmi audio even if the signal was working ... Now the hdmi audio is heard but the desktop is not seen !! Excuse my poor English... I'm Italian.
