I am using a Librem 14/Pureos Byzantium and the display started randomly blinking (to black) for as much as 2 seconds just today. This problem has happened before, last year, and after a kernel update it stopped.
Do any librem 14 users have any suggestions? Using the 5.10.35 kernel now.
And keyboard response during the ‘blinks’ repeats keys – which is new.
Have not made any changes recently other than removing old kernels the supposedly
safe way with dpkg–leaving current kernel and a backup. I also have the librem-ec-acpi module loaded.
