it's not X to blame, but the one that starts it so moving to gdm3 hoping
that someone would have a clue

So let me summarize your findings on the same host of yours (I suppose
your VMs use the same config for the number of vCPUs and the memory
size. I also suppose you only tested Hyper-V Generation 2 VMs or you
confirmed Gen-1 vs. Gen-2 makes no difference):
("fast" means you can see the GUI desktop
Hi Dexuan,
Sorry for delay in answer - I have installed fresh Server 19.10
(installation is of course different - EFI partition setup by installer,
etc. etc.) and after kernel boot messages I've got immediately login
prompt.
After that I've done "sudo apt-get install ubuntu-desktop" and issue is
Can Ubuntu devs please try to repro the issue? I can not repro it. :-(
Hi M, I assume you can also repro the issue with a VM created from
scratch from the server .iso (see comment #28) with a minimal
installation? If yes, can you please share the vhdx file? If you
configure the disk size to 15GB
Dear Ubuntu devs,
issue was reported on 17.10 and still - Ubuntu 19.04 starts fast, Ubuntu
19.10 upgraded from 19.04 / installed from scratch starts very slow.
ANY IDEAS?

The typical boot-up time of my Ubuntu VM on Hyper-V is 20~30 seconds for
a Desktop version of Ubuntu, and 10~20 seconds for a Server version. I
tried Ubuntu 19.04 just now and it also took 20+ seconds.
I never achieve a boot-up time of 2s.
I do know Ubuntu can boot up fast in 2~3 seconds in WSL
Hi,
If possible, please try 19.04 or LTS 18.04 and compare startup time - my
guess is that it will start almost immediately and you will see, that
you already reproduced it :)
I'm sure let's say in 90% :) -> 28 seconds is looonnnggg (like I said,
I've got about 2 seconds for older Ubuntu).

Hi M, since I can not reproduce the delay issue, I don't know what I can
do now. :-(
Do you think if it's related to Xorg?
Can you install a new VM from scratch from the server .iso
(http://releases.ubuntu.com/19.10/ubuntu-19.10-live-server-amd64.iso)
and see if you can reproduce the same issue?
Hi,
Thanks for comments #25 and #26,
I don't know how fast is your machine, but on mine earlier (before
19.10) I had startup in just few seconds, now have this delay. Yes, this
is maybe not critical, but should be fixed, because can go into Ubuntu
20.04 ;)
Anyway, I'm using stock kernel 5.3 +
I'm not sure what exact issues you're reporting.
Your VM takes too much time to boot up? How long? "systemd-analyze
blame" should collect the info for your VM.
Your VM's screen is somehow messed up temporarily during the boot-up
process? Or the boot-up process is stuck in the "text cursor"
Hi M, I can not reproduce the issue: just now I downloaded
http://dt0cinyuc0rrg.cloudfront.net/ubuntu-19.10-desktop-amd64.iso and
created a Generation-2 VM on Hyper-V with the .iso file. The VM boots up
fast: it boots up to the Xorg desktop in 28 seconds with 1 CPU and 2GB
memory, and in 21
I've tried to (1) boot the same machine with kernel 5.0.0.32 (2) create
new machine without upgrading from 19.04
Results were the same, anybody?

One thing, which I didn't mentioned earlier:
there is graphic artifact (color on half of screen), then "Ubuntu
loading" dots, then text cursor with delay, then login screen.
I forgotten about "Ubuntu loading" dots.
lspci -k output is empty (even with sudo), the rest is attached.
