For 19.04, I am working on it because I found some strange issue with HDMI too after installing it.
Boot system connected with HDMI connected, first it shows only blank purple magenta and after a minute, only blank black screen. Power off the smart station, disconnected both HDMI, VGA, and boot the system and after completion of booting, connect the HDMI, it shows login screen. I will give you a log. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gdm3 in Ubuntu. https://bugs.launchpad.net/bugs/1812359 Title: Cannot install Ubuntu 18.04 in Intel Atom D425 when an external monitor is connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1812359/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
