I've hit this issue a number of times recently, and again today. Real problems with multi-head configuration (*non* RandR) on intel & modesetting at least .. Ubuntu 18.04 so xorg 1.19.6.
With intel(4) driver, after much guessing of CRTC numbers (would be really good if xrandr(1) could print them!) I managed to get two multi-head displays up, but the first/left-hand side was broken in all sorts of odd ways, screen not refreshing properly, responding extremely slowly to input, etc., etc. Second display is fine - almost like the server itself was confused rather than the gfx driver? xorg.conf: https://pastebin.com/N7sR34J4 So I tried with modesetting(4) and can't even get it to see the second display: [ 2090.926] (**) modeset(1): Option "ZaphodHeads" "1:HDMI-1" .. [ 2091.032] (WW) modeset(1): No outputs definitely connected, trying again... [ 2091.032] (WW) modeset(1): Unable to find connected outputs - setting 1024x768 initial framebuffer .. [ 2091.032] (EE) modeset(1): No modes. Same if I specify pipe 2. Full Xorg.log here: https://pastebin.com/iACXeZGV xorg.conf: https://pastebin.com/dhxihvKd Thoughts appreciated! Steve
