I have the same bug on a similar motherboard - Asrock j4105-itx (j4105 CPU, asmedia asm1061, realtek rtl8111h) After the boot sequence KUbuntu 18.04 fully updated to Nov-19-2018 Bios 4.0.0.1245 Intel GOP 13.0.1011
I doubt this is the same as the freedesktop 105549 bug since the hardware is quite different (no lspcon chip on this motherboard) Also note that the problem only arises when a disk is connected to one of the asmedia sata ports on this motherboard. If no disk on asmedia all is good. No HDMI or DVI screen if disk on asmedia port Windows (8.1) does not experience this issue .... BUT does not have drivers for this chip at all (Vesa only)> I don't currently have access to Windows 10 When the VGA port is connected to a screen then BOTH the vga and hdmi / dvi screens are active ie. the hdmi / dvi output is live if vga simultaneously connected ... though vga is primary May be spurious, but fwiw, under these conditions ... The system will not power down correctly (even if both VGA and hdmi / dvi connected). Powerdown seems to stop after a message about "ata3 SError" "failed command STANDBY IMMEDIATE" and then a manual power off is required Any debug data I can provide ? -- 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/1792144 Title: missing patch for i915 in 4.15.0-33-generic => black screen on boot Status in linux package in Ubuntu: Triaged Status in linux source package in Bionic: Triaged Bug description: we must use i915 with modesetting, because else the hdmi-audio isn't available. enabling modesetting, the monitor went black immediately after dmesg: fb: switching to inteldrmfb from EFI VGA Console: switching to colour dummy device 80x25 [drm] Replacing VGA console driver for this bug at https://bugs.freedesktop.org/show_bug.cgi?id=105549 there seems to be a patch available which doesn't seem to be integrated in last available xenial-kernel 4.15.0-33-generic. please integrate it in next kernel-update.
