手动调整:
- switch to an other vt (e.g. Ctrl+Alt+F6)
- run
sudo sh -c "echo -n <level> > /proc/acpi/video/NVID/LCD/brightness"
where <level> is 0, 10, 25, 40, 55, 70, 85 or 100
-------------
开机自动运行:
sudo gedit /etc/init.d/rc
在
PATH=/sbin:/usr/sbin:/bin:/usr/bin
export PATH
之前加入:
sh -c "echo -n <level> > /proc/acpi/video/NVID/LCD/brightness"
即可实现开机自动调整。
