   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
