Seeing I can't make work the second monitor I installed on 20.04 the 4.15 kernel. Now it works, so this is for sure something about the kernel. On 4.15 and higher, the second monitor doesn't work.
Tested on 5.8. And it doesn't work neither. ** Bug watch added: gitlab.freedesktop.org/drm/intel/-/issues #2181 https://gitlab.freedesktop.org/drm/intel/-/issues/2181 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871721 Title: Second Monitor on HDMI blank screen/blink screen with Nvidia + Intel & Ubuntu 20.04?
