Hi, I'm running 4.18.5-a-1 hardened with a 35" Sharp HDMI TV and an ASUS K53E laptop, owing to the fact that I can't use the monitor which got damaged due to a display flex-cable mishap during service. The TV seems to want to keep itself at either 1080p or 800x600@75 Hz. The problem with this is, after I mount my root partition via cryptsetup the TV screen blinks like crazy for a few seconds (switching from initramfs video mode to 1080p) and goes black unless I use "nomodeset i915.modeset=0" on the GRUB command line.
I looked at help pages describing my problem and tried inserting the i915 and intel_agp modules into the initramfs for early KMS. That just made it worse and I couldn't even see to unlock the root partition after that. I've tried fiddling with my TV's display settings, I've tried xrandr, reinstalling the kernel, and I've even used an Ubuntu LiveUSB which itself gets stuck at 800x600 with "unknown monitor." The only other option I'm left to consider is that this may be an EDID issue.
I'd like to be able to use my LightDM again and I'll get whatever log/configuration files I need to but they're going to have to be mounted from another system later on today.
