Dann,
For the wanland issues, I understood it as comments in #15, that is:
Blur screen for GDM login was caused by wayland, it can be fix by force
to use Xorg in
/etc/gdm3/customer.conf to uncoment WaylandEnable=false
Is this right for your wanland issues on D05?
In 18.04, we found 2 issues on Huawei X86 server. One is screen blur
during d-i install on UEFI model in Language selection screen, but it
works for legacy bios model. The other is after start GUI (x-window or
Ubuntu desktop). After we sucessfully installed 18.04 in legacy bios
model on X86 Huawei server, I tried to start X-windows via apt-get
install ubuntu-dekstop and reboot, we would get this blur screen again.
This seems caused by this wanyland and can be fixed by this
"WaylandEnable=false".
As I know, this wayland issues have been happened for D05 but I don't think D05
have above issues
during install.

Bug description:
For all(as I know) Huawei servers, the vga adapter are embed in the
iBMC chips. Those server can install from ISO manually for 16.04.4 and
screen display normally. But for 18.04 ( tested both for daily and
final beta)version, the install screen is blur. One of tested server
is Huawei 2855 v5, the certification link for 16.04 are
https://certification.ubuntu.com/hardware/201707-25596/.
Below are key difference of dmesg. It seems might related with DRM.
