I tried to change the cursor theme from DMZ-White to DMZ-Black for my laptops. But it does not work for one of my laptop.
For that laptop, it does not work no matter I change the cursor theme in - Ubuntu tweak tool, - or changing it in gksu gedit /usr/share/icons/default/index.theme, - or changing it in sudo update-alternatives --config x-cursor-theme
What else can be done to change it? Thanks in advance!
==edit== sorry turns out that my mouse cursor is partially changed.... in the main content of firefox browser, the cursor is changed to black, however if the cursor is on the launcher / File/Edit/View bar, it is still white.
