我的电脑在启动到acpid的时候屏幕亮度会重置(full brightness),比较的烦人
另外,在gome中退出登录,回到等候登录对话框中时,屏幕亮度也会重置
今天看到laptop-mode中有关配置,它告诉我有两种方式可以进行亮度控制。我自己尝试了一下
echo value > /sys/class/backlight/.../max_brightness的方式对本机有效
故,我在laptop-mode中相关文件出进行了修改,在/etc/X11/xinit/xinitrc中进行了修改。
结果,前面说的问题其实依然存在,只是很快会自动改变为我设定的亮度值。我无法将亮度保持在一个恒定不变的值。
关于这一点,想问问大家是否有什么进一步提示,例如,是否和内核设定有关,或者其他什么有关。
Remark1: 在本机/proc/acpi/video/VID/LCD/brightness类似的地方,brightness的值为<unsupported>
# * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
# be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
# the command "echo <value>". The possible values can be listed using the
# command:
#
# cat /proc/acpi/video/VID/LCD/brightness
#
# * If you have a file /sys/class/backlight/.../brightness, then you can use
# that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
#
# As far as I understand it the values are between 0 and
# the value contained in the file /sys/class/backlight/.../max_brightness.
#
# * For Toshiba laptops, use the command "toshset" with the -lcd or -inten
# command. Read the toshset(1) manual page for more information on the
# parameters for this command. If you use this command, set
# BRIGHTNESS_OUTPUT to "/dev/null". |
