Добрый день. Все борюсь со своей леновкой, сусей и видеодрайверами.
Нельзя регулировать яркость экрана ноутбука ни с клавиатуры, ни из "управление электропитанием". Попросту экран на это никак не реагирует.
[console]uname -a
Linux localhost.localhost 3.11.6-4-desktop #1 SMP PREEMPT Wed Oct 30 18:04:56 UTC 2013 (e6d4a27) x86_64 x86_64 x86_64 GNU/Linux[/console]
При нажатии FN+XX в dmesg светится вот это:
[console]dmesg
[ 131.475759] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
[ 131.475764] thinkpad_acpi: unhandled HKEY event 0x6050
[ 131.475766] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net
[ 132.462868] thinkpad_acpi: unknown possible thermal alarm or keyboard event received

[ 132.462874] thinkpad_acpi: please report the conditions when this event happened to ibm-acpi-devel@lists.sourceforge.net[/console]
Периодически на экране появляются полосочки, типа "ты 5 минут не трогал ноут я снизил яркость до 75%" или "ты вставил зарядное устройство, я поднял яркость экрана до 100%" но это не имеет никакого отражения на яркости экрана. куда смотреть, куда податься?
