How to avoid dark colour of some programs in LXDE no matter the theme?
Solution 1:
You are having a problem with your qt applications not honoring your gtk theme.
What you do is install qt4-qtconfig and set your qt applications to honor the gtk theme.
sudo apt-get install qt4-qtconfig
qt4-qtconfig
At least on Lubuntu 14.04.02 instead of qt4-qtconfig one should use
qtconfig
In the "Select GUI Style" box, select "GTK+"
