I repeated the same SRU verification as before, this time using kmod from -proposed.
I installed a fresh Bionic KVM, with EFI enabled. I upgraded the system to use the latest -updates packages. Linux 4.15.0-99-generic and Kmod 24-1ubuntu3.3 were installed. I shut the machine down, set the VGA device to vga=std, and rebooted. The screen was garbled and unreadable. I then ssh'd in, enabled -proposed, and installed Linux 4.15.0-100-generic, and kmod 24-1ubuntu3.4. I rebooted, and the display came up great, and was perfectly readable. Attached screenshot as proof.
