Hello, Another similar bug report has been opened here [1] for a different computer model (different CPU, different GPU) with a possible solution [2]. Perhaps you could test if solution in [2] applies to your computer, too.
Hope that help. Bye. [1] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=989705 [2] https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=989705#30
