[РЕШЕНО] При запуске иксов яркость равна нулю

Я не пойму, почему ты не хочешь воспользоваться советом Кусок
Я только сейчас вставил в автозагрузку команду xbacklight -set 70 — надоело уменьшать яркость после старта — все работает, ничего больше не нужно.
Для гнома
$ gnome-session-properties
и добавляешь xbacklight -set 100
И все, больше ничего.
Ошибки не исчезают с опытом - они просто умнеют
Помогло! Отпишу подробнее что надо сделать если у кого-то возникнет такая же проблема.

Добавьте в /etc/default/grub в переменную GRUB_CMDLINE_LINUX параметр acpi_backlight=vendor
Сгенерируйте снова от рута grub.cfg:
grub-mkconfig -o /boot/grub/grub.cfg
Это чтобы при каждой генерации правило само добавлялось, если обновлять файл настроек grub не планируется, то можно добавить в /boot/grub/grub.cfg в опции загрузки строку acpi_backlight=vendor.

Нафаня, большое спасибо. =)
Keep it simple, stupid!
Ах, как я обрадовался, прочитав про параметр ядра. Прописал, сгенерировал (мог и просто в конфиг прописать). Ну до все бестолку - иэто в моем случае, а случай такой-

Интел Хасвелл, hd5000, ось что Убунта, что Деб, что Федора, что Сусь, что Arch (на котором и остановился). Картина общая на любом ядре - при запуске системы подсветка адекватно регулируется в полном ее диапазоне, от нуля до максимума. До первого ждущего режима. После чего только два крайних максимально ярких режима. Причем при пробуждении моргнет на том уровне подсветки, на котором заснул, и гаснет. И после этого только кнопками регулировки подсветки до максимальной яркости. На Иксы не грешу - перезапуск Иксов не влияет, только полная перезагрузка. Наличие или отсутствие в системе пактом acpi, laptop-mode на ситуацию не влияет.

Где собака порылась? -

уходим в сон (чуть подвигал яркость кнопками)

Вручную (через echo) не работает? Здесь пример есть.

Увы, в буржуазных языках я для детального их понимания слаб. Тем не менее у меня нет /sys/class/backlight/acpi_video0/max_brightness, вместо acpi_video0, понятно дело, intel_backlight, но (рут) -

echo 2777 > /sys/class/backlight/intel_backlight/max_brightness
bash: /sys/class/backlight/intel_backlight/max_brightness: Отказано в доступе

Проблема не в том, что нет регулировки подсветки, а в том, что до первого сна по шкале от 0 до 10 есть все значения подсветки, а после первого же сна есть 0, 9, 10. При том, что с подсветкой клавиш все ОК, полная шкала.
Чтобы просмотреть конкретно лог того, как ломается подсветка, перезагрузился, уснул, проснулся

Вроде все проходит штатно, без ошибок, кроме вот этого сообщения -
ACPI group/action undefined: video/brightnessup / BRTUP

Пошел гуглить.
Подсказанное гуглом решение https://wiki.archlinux.org/index.php/Talk:MacBookPro не работает (да, я не забыл скорректировать нвиду на интел)
Кстати, последнее время я перестал указывать acpi_backlight=vendor, с яркостью проблем нет. Видимо в ядро вшили что-то. :)
Keep it simple, stupid!
