I installed the Ubuntu-16.04.3-server-arm64 (hwe) on my ARM64 server.

enter image description here

Then I execute:

apt update && apt dist-upgrade && apt install ubuntu-desktop

Then I reboot. However, I can't see anything about desktop, I even can't see the ubuntu logo, which should have appeared before user login interface. But ssh on it is possible. So I think it's the problem of desktop.

I just checked the xorg log, there are some errors but I don't know what to do:

Here is the info about the graphics card:

It seems that upgrading the kernel can invoke this bug, which means that for now I can't upgrade the kernel from 4.10.0 to 4.13.0.

I've found an error saying that Failed to load module "fbdev" in the log of Xorg

Here is what I've done to solve this issue:

apt update
apt-mark hold linux-generic-hwe-16.04
apt-mark hold linux-headers-generic-hwe-16.04
apt-mark hold linux-image-generic-hwe-16.04
apt dist-upgrade
apt install ubuntu-desktop
apt install xserver-xorg-core-hwe-16.04 xserver-xorg-video-fbdev-hwe-16.04 && reboot

I don't know why but somehow apt install ubuntu-desktop doesn't install xserver-hwe packages automatically, whereas ubuntu16.04 on X86 do it automatically.

Maybe it's because I didn't upgrade the kernel?
