I am also facing this issue.
I have a NEO Z84-4 V2 Pro that had Windows 10 installed. I have followed the instructions in the other forum posts to take note of the Windows License Key etc.
I then used Rufas to create a boot stick using
Z83-4U-Ubuntu_2018.04.01-20181029.iso
For this install, the workaround on this forum works in that I can access the desktop by going in via recovery mode. But that is where the story ends. I did apply the patch as described. It all seemed to go well, but the boot up is still not correct. I do wonder if it is to do with the kernel version - This seems to be using 4.15.0-99-generic (I am not Linux build expert so I am a bit out of my league with this issue).
I did try
Z83-4U-Ubuntu_2018.04.03-20191104.iso but there is no activity on the screen what so ever - even when "trying Ubuntu before installing". It just stays blank and there is no purple screen.
In case it is useful, based on the posts above, for the Z83-4U-Ubuntu_2018.04.01-20181029.iso I checked the following ...
uname -r
4.15.0-99-generic
Before applying the patch
ls -l /boot/vmlinuz*
-rw-r--r-- 1 root root 8257272 Mai 10 18:55 /boot/vmlinuz-4.15.0-29-generic
-rw------- 1 root root 8380056 Apr 22 20:32 /boot/vmlinuz-4.15.0-99-generic
After applying the patch
ls -l /boot/vmlinuz*
-rw-r--r-- 1 root root 8257272 Mai 10 18:55 /boot/vmlinuz-4.15.0-29-generic
-rw------- 1 root root 8357664 Okt 1 2019 /boot/vmlinuz-4.15.0-65-linuxium
-rw------- 1 root root 8380056 Apr 22 20:32 /boot/vmlinuz-4.15.0-99-generic
Any advise or tips would be appreciated. Note that I was intending to use this mostly in a headless mode so with SSH setup, I could work with this if there is no immediate solution.
