Hi 
Thank you for this excellent guide, I have been using it for years. Recently I installed Ubuntu server 23.10 on a Fujitsu thin client S940 (Gemini Lake). I installed Kodi from the Ubuntu repository, not the PPA (since Kodi PPA doesn't work). I also installed Gnome Desktop minimal.
 

Code:

sudo apt install ubuntu-desktop-minimal

 I normally switch between Kodi standalone full screen and Ubuntu wayland Gui using the openbox login window.
But something isn't working right here.
Often, when using the login window after selecting the user and Kodi or Ubuntu, I get a black screen (no connection) and only unplugging the TV and plugging it in again gives the image. The new computer only has two DisplayPort ports. so I use a DP-HDMI cable adapter to connect to the TV (4k Oled LG).
What do you think about it? Maybe something is starting too fast and that's why there's a black screen?
Is it possible to reduce the resolution and refresh rate of the openbox login window lets say to 1920x1080? In full 4k resolution, the elements are very small and inconvenient. Maybe I should change something in /home/kodi/.config/openbox/autostart file?
