我最近升级到了4.4.0-53-通用内核，现在勒克斯不起作用。我让它在启动时启动，但现在它根本无法更改温度颜色设置：
以下是启动的输出fluxgui：
/usr/lib/pymodules/python2.7/fluxgui/fluxgui.py:162: GtkWarning: Cannot transform xsetting Net/IconThemeName of type gchararray to type GdkColor
'gtk-icon-theme-name')
/usr/lib/pymodules/python2.7/fluxgui/fluxgui.py:162: Warning: g_value_unset: assertion 'G_IS_VALUE (value)' failed
'gtk-icon-theme-name')
/usr/lib/pymodules/python2.7/fluxgui/fluxgui.py:162: GtkWarning: Cannot transform xsetting Net/IconThemeName of type gchararray to type gint
'gtk-icon-theme-name')
在考虑这个错误仅仅与这些 GTK 相关的问题有关之后，我通过修改第 162 行解决了这个问题：
/usr/lib/pymodules/python2.7/fluxgui/fluxgui.py.
如下所述这个答案遇到类似问题，但这并没有让 F.lux 恢复运行。我接下来要做的是在终端中打开 f.lux：
fluxgui
然后点击小程序指示器并选择“首选项”。终端中的输出如下：

在毫无进展之后，我决定重新安装 Flux，这似乎让我可以访问在重新安装之前无法正常工作的首选项窗格，但是当我更改位置甚至预览时什么都没有发生，而这两项功能以前都可以正常工作。
