Why won't NVIDIA X Server Settings configuration save on reboot?

Question

I'm on a 64-bit machine running Debian 8.2 "Jessie" with MATE Desktop Environment.

I have a Geforce GTX 650ti video card.

I'm logged in as a non-superuser account named "john."

I open NVIDIA X Server Settings GUI, change my monitors' brightness from 0.000 to -0.1, go to the "nvidia-settings Configuration" section, click "Save Current Configuration" and click "Quit."

但是当我重新启动时，亮度又回到了 0.000。

为什么？

我该如何解决？

Answer 1

它不会自动使用此配置，而是您必须手动加载它，例如通过自述文件中显示的方法之一，或者您自己最喜欢的在登录时启动某些内容的方式。您正在寻找的命令是nvidia-settings --load-config-only.

4.  Loading Settings Automatically

The NVIDIA X driver does not preserve values set with nvidia-settings
between runs of the X server (or even between logging in and logging
out of X, with xdm, gdm, or kdm).  This is intentional, because
different users may have different preferences, thus these settings
are stored on a per user basis in a configuration file stored in
the user's home directory.

The configuration file is named "~/.nvidia-settings-rc".  You can
specify a different configuration file name with the "--config"
commandline option.

After you have run nvidia-settings once and have generated a
configuration file, you can then run:

    nvidia-settings --load-config-only

at any time in the future to upload these settings to the X
server again.  For example, you might place the above command in
your ~/.xinitrc file so that your settings are applied automatically
when you log in to X.

Your .xinitrc file, which controls what X applications should
be started when you log into X (or startx), might look something
like this:

    nvidia-settings --load-config-only &
    xterm &
    evilwm

or:

    nvidia-settings --load-config-only &
    gnome-session

If you do not already have an ~/.xinitrc file, then chances are that
xinit is using a system-wide xinitrc file.  This system wide file
is typically here:

    /etc/X11/xinit/xinitrc

To use it, but also have nvidia-settings upload your settings,
you could create an ~/.xinitrc with the contents:

    nvidia-settings --load-config-only &
    . /etc/X11/xinit/xinitrc

System administrators may choose to place the nvidia-settings load
command directly in the system xinitrc script.

Please see the xinit(1) manpage for further details of configuring
your ~/.xinitrc file.
