Update:
There are two ways to use Mali on VIM1:
For Closed Source mali driver, Fenix is supported, and you can build Ubuntu Mate 16.04 with X11 GPU support, but the mali blobs provided by Amlogic is defective, the fps of glmark2-es2 is only 7.
Lima for X11 is still not usable, you can find some information here:
Well, i am not sure if they are using lima drivers, you can see on @narmstrong github that mali is updated, i really donāt care if it is open source or not, as long as it works, probably lima will be much better than closed driver once it matures.
Nice article about lima driver: https://www.phoronix.com/scan.php?page=news_item&px=Lima-DRM-Driver-Mainline-V2.
Is this image to SD or eMMC?

There is no image in this link, it is an article!
This image is for Emmc only.
And can be installed with sing USB-C Cable
(Upgrade Using USB-C Cable https://docs.khadas.com/vim2/UpgradeViaUSBCable.html)
I already tried but it fail.
Other files to eMMC with same procedure worked well.
Didnāt try to install it, so i canāt really help you, if you are using usb burning tool, try to change usb port, maybe that silly solution could help.
[Is possible to put the wifi working on this image (http://VIMs_Ubuntu-xfce-bionic_Linux-4.19_arm64_SD-USB_V20181030)
Both Ethernet and wifi are working.
I have the VIM2 Max. Is this your case?
Ethernet is working but Wifi not.
I was searching the forum but didn`t found anything that solved the problem with wifi with this image (see it in previous post).
Any help would be appreciated.
thank you.
I am using Vim 1, i thought you were too, wifi works only in Vim2 2/16.
This is the mali used, DX910-SW-99002-r7p0-00rel1_meson_gx, not lima.
Off topic
I install this Rom on my VIM2 MAX that works very well.
I would like to add a few applications to complete my āPortable Desktopā. 
One of them is a Vivaldi Browser.
I tried to install it but it fail some dependencies.
Probably my source list needs some additional repositories that I could not found.
Any help would be appreciated.

Solved. 
You can now browse with Vivaldi on the recent models of the Raspberry Pi (2/3), along with other boards (and devices), such as CubieBoard and ASUS Tinker Board. Vivaldi for khadas is not build
Dear Khadas team!
Donāt you think that if you sell a device and declare Ubuntu support, that mean you should offer the latest full feature working LTS build with mainline kernel or at least drivers working with the mainline kernel?
Iām talking about WiFi on VIM2 Pro.
I understand that you are not developers of the driver, however I suppose you had to have some agreements with chip vendors about driver support.
User decision to buy or not to buy a product is based not only on a good hardware, but on software and support too.
Have you made any request to a vendor in order to get a Wi-Fi driver for VIM2 Pro for mainline kernel? What is the answer?
Thank you!
Do you mean mainline kernel? If so will update to 5.0 in next week.
Please share the mainline linux kernel source.
I will try to compile it for arch linux/manjaro
