Astralix Posted August 10, 2017 Posted August 10, 2017 Hi there! I am new to this forum, so hopefully I am at the right place to open my discussion. We use our own made iMX6DL based board to run a semi-professional amateur radio. We choose armbian as it worked almost out of the box, but we use a kernel 4.11+ probably 4.12+ next week with some small extra drivers for an SPI OLED and some special keyboard drivers. However these modifications are not relevant for the issue I have, but I should mention, that I added the etnaviv kernel drivers and all related things to activate HDMI. We have not fully encountered the way to merge in our BSP to armbian, however I found the very instructional videos in the other topic and I'll prepare for that in the next weeks. Til then we provide update-images for our users, later we move to "apt update && apt upgrade". Now here's my issue... The armbian driver set before 5.30 (4 weeks ago) worked fine and we had a desktop on the HDMI, as long as you 1) start the unit with a switched on HDMI monitor connected and 2) never turn off that monitor, as that results in a blank screen. Two weeks ago, we tried an armbian upgrade (yes we disabled the BSP package upgrade, as we provide our own.) and HDMI was working, but the screen stays black. Pressing ENTER revealed that the text console works, but X11 refuses to start. It detected the monitor and such but then failed with almost no in-depth error information. So we reset to our initial image and worked on our radio software and on Monday this week I tried again to upgrade. Lucky me, this time, the HDMI worked after the upgrade. Unfortunately yesterday we did another upgrade to (if I am correct) 5.31 and now the HDMI stays black again, only working as a text console. "startx" just confirms a fine monitor but then fails. We do need the desktop working, as that is one option to use the box as an amateur radio and control it via the chromium browser. We currently do not need any 2D / 3D acceleration. I have to mention, that the unit also has an OLED running as a framebuffer device but that is not mapped to any console, so the x server should not take over its control (it should run the amateur radio control while the user can use the armbian desktop at will) [ 1211.676] (II) modeset(0): Output HDMI-1 connected [ 1211.676] (II) modeset(0): Using exact sizes for initial modes [ 1211.676] (II) modeset(0): Output HDMI-1 using initial mode 1280x720 +0+0 [ 1211.676] (II) modeset(0): Using default gamma of (1.0, 1.0, 1.0) unless otherwise stated.

So why does the current update fail on that fbdev while the last one did not? Would appreciate any help that gets the desktop back onto the HDMI and as a bonus, the makes the Desktop steady working even the HDMI monitor is switched off or disconnected? Astralix
Astralix Posted August 11, 2017 Author Posted August 11, 2017 So, it looks like I have an update on that... I do not know why the old and the not so old version of armbian simply used the HDMI as a default display, while the other two versions fail. But it seems, that the issue is the presence of /dev/fb0 and /dev/fb1 and the missing /dv/fb. I added a new configuration file /etc/X11/xorg.conf.d/99-hdmi_fb0.conf Section "Device" Identifier "main" driver "fbdev" Option "fbdev" "/dev/fb0" EndSection That forces the x-server to use /dev/fb0 and the additional OLD doesn't interfere anymore. So at least one issue is solved.
