一直很明亮，从未被超越～～～

问题：thinkpad r400 的开机亮度太亮
情况：由于是双显卡，我装了intel驱动发现开机加载过程中，亮度达到最大。于是我拆卸了intel驱动，装上了ati驱动，却发现只有在加载udev的那一瞬间亮度达到顶峰后就恢复到我对于gnome的设置，之后我试过了catalyst和radeonhd但都没法解决，显卡是3470。
请大家热心来讨论下，发挥大家的天才大脑与智慧。

用热键调节，balabala。

可是每次都要调节下，或许，我怕的不是麻烦，而是屏幕，每次都跳到最亮，很伤阿。

搞不清老外的眼睛到底是好还是差，默认竟然是最亮，看老外的桌面截图，字却又都是超小超小的！

英文字小的时候好像也可以看清，但中文就不行了

那么大家有好的解决方法么？我还是很迷茫阿。

我的是装laptop-mode 然后修改最后几行
# cat /etc/laptop-mode/conf.d/lcd-brightness.conf
#
# Configuration file for Laptop Mode Tools module lcd-brightness.
#
# For more information, consult the laptop-mode.conf(8) manual page.

# LCD brightness settings
# -----------------------
#
# Using these settings, you can make laptop mode tools automatically adjust
# your LCD's brightness settings. The settings are extremely simple -- they
# only allow for the execution of a command, nothing more. The reason for this
# is that LCD brightness settings are very different between laptop vendors.
#
# Suggestions for commands:
#
# * 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".

#
# IMPORTANT: In versions 1.36 and earlier, these settings were included in the
# main laptop-mode.conf configuration file. If they are still present, they
# overrule the settings in this file. To fix this, simply delete the settings
# from the main config file.

CONTROL_BRIGHTNESS=1


#
# Commands to execute to set the brightness on your LCD

BATT_BRIGHTNESS_COMMAND="echo 11"

BRIGHTNESS_OUTPUT="/proc/acpi/video/VGA/LCDD/brightness"

grub/menu.lst 里加上 acpi_backlight=vendor

以上的办法我都试过了，还是没有办法，开机是还是暗的，当读到loopback......de 时候就大放异彩，然后回到gnome时又暗了........

我提供的方法试过了么？

我和你的机器一个型号
以前也有你的问题
不过用那个方法解决了

我用的intel

谢谢你了，crazyatom，我以前加错了行了，所以没能成功，现在我看到你的再次留言，我很感动，所以我一行一行地加，结果在第二行就成功了。现在我也更了解了grub了。

你也是双显卡啊?
我现在用intel显卡, 在linux里把ati屏蔽了, 不然会多耗10w
现在也能和windows续航能力差不多了
