Public bug reported: I have the kernel load an EDID file so that when connecting my amd64 machine to a tv and speaker bar through hdmi I get the full setup information even if the speaker bar and tv might be off.
The relevant kernel cmdline is "drm.edid_firmware=HDMI-A-1:edid/edid.bin" In most recent kernel versions this hasn't been a problem. The mainline 5.2.0-rc7 generic kernel at https://kernel.ubuntu.com /~kernel-ppa/mainline/v5.2-rc7/ works properly. The 5.2.0.8.9 kernel in eoan/proposed at https://bugs.launchpad.net/ubuntu/+source/linux-meta/5.2.0.8.9 however does not work, insofar as I get no video output at all after grub loads the kernel. (I would test with the 5.2.0 mainline generic kernel, but the mainline kernel builds are currently broken due to issues with gcc-9.1 flags.) dmesg and Xorg log for boots for both kernels (working and not working) are attached.
