Suspend не работает (cat / proc / acpi / bbswitch убит)
У меня есть ноутбук nvidia optimus (Thinkpad P50), и я не могу приостановить его после недавнего обновления.
Мне удалось отладить это до следующей команды, которая не выполняется:
$ cat /proc/acpi/bbswitch
[1] 4564 killed cat /proc/acpi/bbswitch
dmesg печатает следующее:
