 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.
