FWIW, I just finished installing Ubuntu Server 16.04.02 and then upgrading it to the latest on Jan 11, 2018. I have a command line only system (it is just a really basic firewall) and the keynel is logging messages like this:
Jan 11 09:23:42 speedy2 kernel: [64428.303428] [drm:radeon_vga_detect [radeon]] *ERROR* VGA-1: probed a monitor but no|invalid EDID every ten seconds. I am using an old VGA monitor because I really don't need a screen unless something goes wrong, but sadly, the only thing currently wrong is that the kernel won't shut up about the monitor! So, I leave the monitor unplugged until I need it in order to keep the noise level down. I wonder if the radeon driver will ever be fixed for this? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1663727 Title: 16.04.2 LTS (4.4.0-62-generic) now spewing EDID vga radeon errors Status in linux package in Ubuntu: Confirmed Bug description: I've just performed an "apt-get update" on a Dell 2950 Server - which was already running 16.04.1 and now it's spewing EDID errors - I'm not sure what changed from 16.04.1 to 16.04.2......
