I have a brand new VIM4 NPU bare board in fanless aluminum case with power supply and Khadas cable.
Khadas Ubuntu versions with gnome desktop work perfectly without any slowdown in both emmc and sd version but armbian desktops do not work!
Only xfce (via oowow or latest armbian.com version) launches after several minutes but then presents slowdowns.
All versions with cinnamon (oblique lines) and gnome (armbian logo) freeze after launching the desktop environment whether with an installation on emmc sd or usb…
No problems with server versions, only desktop versions…
I wonder if it is the fact of not having a fan and/or the NPU chip that makes the Armbian desktops incompatible?

I would recommend you to get a fan. Vim4 does run hot. But its not the cause of the issue. The same issue is also there on the NPU model

 

We are aware of the issue and are working on the same. Please be patient. A fix will be released once ready

Thank you, for my use (currently ubuntu 22.04 gnome with home assistant core, nodered, mosquitto, more than 20 Firefox and Chrome tabs open...) the static cooling provided by the aluminum case is more than sufficient...

The February 13 versions work (USB test of Bookworm Gnome and XFCE) Thank you!

@Gunjan Gupta is there some plan to get cinnamon UI running?
Cause I tested almost every combination with cinnamon UI and non worked for vim4.

Thanks for reporting, I will take a look and get back to you on the same. 

I had to add EXT=xorg-lima-serverflags EXT=mesa-vpu for the build so that any UI worked.
