Correct, they are 2 separate things, I thought this was clear I apologize if it wasnt. > > > ``` > > ls -l /sys/class/drm/card0 > > lrwxrwxrwx 1 root root 0 May 19 13:17 /sys/class/drm/card0 -> > > ../../devices/pci0000:00/0000:00:02.0/drm/card0 > > ``` > > Is this the working case?

What I have actually found is if: 1) SeaBios loads the option rom (working config) - card0 doesnt exist - card1 does exist and edid is properly found there - resolution on boot detects proper monitor resolution (1024x600) 2) Coreboot loads the option rom (working config) - card1 doesnt exist - card0 does exist and edid is properly found there - resolution on monitor is 1024x768 on boot and then properly adjusts to 1024x600 when OS takes over 3) Coreboot is misconfigured/does not load option rom OR coreboot configured to use libgfxinit (non-working config) - card1 doesnt exist - card0 does exist, but edid is empty - no display on boot and then adjusts to 1024x768 once OS takes over This is maybe expected outcome, or interesting, I am not sure > Btw. did you give the physical connections a look?

I've inspected the motherboard side of the connection and it's fine, I havent looked behind the panel, maybe at some point I will. > If you want to get libgfxinit working again, a log would really be the next > best step.

I then bought a Lenovo docking station. Booted up, everything worked fine. Disconnected from dock, booted up, and there was no bios screen. Screen did not turn on until taken over by Linux Kernel. Once in userspace, wayland could no longer identify the monitor as a Pixel Qi or its proper resolution. EDID is blank. Booting with docking station allows bios to show on external display. Restarting did *not* fix the issue, reflashing heads did *not* fix the issue, flashing skulls (coreboot + seabios) did *not* fix the issue. Flashing stock bios *did fix* the issue. I can now see BIOS screen and get proper EDID in userspace whether on the dock or not. *However* reflashing coreboot again, even coming from stock bios working state, and I immediately now no longer get a BIOS screen or EDID, even without ever introducing the dock again. Essentially now bricked with anything but stock bios. ---Files-------------------------------- cbmem.log (62.6 KB) -- You have received this notification because you have either subscribed to it, or are involved in it.
