The Chuwi Minibook X drivers can be found here:
Installing the drivers is very easy. Download the rar file and use 7zip or WinRAR to open it. Launch the Device Manager. Press the ‘Add drivers’ button. Navigate to the base “minibook x” folder you extracted. Sit back for 10 minutes while everything installs.
I experienced the same display issue. In my case, one of the screen ribbon connectors had worked slightly loose and needed reseating. It’s been more than a week since doing this and I have yet to experience the problem again. I wrote about it here.
Also, for everyone experiencing the screen issue, have you all reloaded the OS and/or changed BIOS settings? I’m seeing a distinct link here between screen issues and OS/BIOS tinkerers. (Myself included).
