 Thank you Salvatore, for moving this forward. 
  
 I can add that the issue has been reported by several users on a GPD DUO 
 channel on Discord -- all are on newer kernels but have different Linux 
 distributions. 
  
 I can also confirm that the patch does solve my problem. Looking forward 
 to some resolution of this, as it stops me from upgrading to Testing. :) 
  
 Best regards, 
  
 Staffan
