   Dear Maintainer,   
      
   *** Reporter, please consider answering these questions, where appropriate ***   
      
      * What led up to the situation? I installed a clean Debian 13 Stable/Trixie   
   and the touchscreen on my GPD DUO worked. After doing a sudo apt upgrade the   
   kernel was upgraded from 6.12.38 to 6.12.43 and the touchscreen stopped   
   working. The touchscreen    
   not working is on the upper screen and is of make Jieli.   
      * What exactly did you do (or not do) that was effective (or   
        ineffective)? Booting again with kernel 6.12.38 made the touchscreen work   
   again.   
      * What was the outcome of this action? The newer kernel does not support   
   the Jieli touchscreen.   
      * What outcome did you expect instead? That the touchscreen continued   
   working.
