Title:
5.2.0-8-generic regresses KMS edid file support, resulting in no video
Status in linux package in Ubuntu:
Invalid
Status in linux-meta package in Ubuntu:
Invalid
Bug description:
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.
