Hi there. Months ago I tried this branch: https://github.com/vsyrjala/linux/tree/skl_vswing_wa_hacks
But the second monitor doesn't work. There's a discussion on https://gitlab.freedesktop.org/drm/intel/-/issues/2181 And no, at the moment there's no a solution. I just found a little fact so interesting. On some monitors, if you set the resolution to 30Hz, the second monitor works. Just on some monitors (the only one was a recent and modern monitor I bought two months ago). Apparently, taking off some Hz it. Never on 60Hz. -- 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?
