Comment 55 for bug 1762940

I installed 4.15.0-56-generic to a bionic VM, with the -modules and
-modules-extra packages. I went into /var/lib/modules/4.15.0-56/ and did a search for
hibmc_drm. There was no mention apart from a header Makefile. The module was not
built and not present on amd64.

I did the same for 5.0.0-22-generic in a disco VM, and the module was not
built and was not present.

4.15.0-56-generic has been installed to a amd64 based Huawei server which was
having the issues explained in this bug, and since the module was not present,
the screen was not "blurry" when a desktop environment was installed and viewed
from the remote access tool used by Huawei.

To ensure that ARM64 still has the kernel module built, I also downloaded
linux-modules-extra for 4.15.0-56-generic for ARM64. The hibmc_drm module is
still present in /var/lib/modules/4.15.0-56/kernel/drivers/gpu/drm/hisilicon/hibmc
This means that Huawei's arm64 based servers will not be affected by the change.

The fixes solve the problems of the video mode not being right for amd64 based
platforms, and does not cause any regressions for ARM64. I am happy to mark this
as verified.
