I'm glad the outside overlay scrollbars are finally gone.
But the scrollbar is still a razor thin line that becomes a less razor thin scrollbar, but still thin scrollbar, when the mouse hovers.
How can I get a normal scrollbar? I.e., like in other OSes, like in Firefox, a scrollbar that doesn't change depending on what the mouse points to, and with a nice width.
I already tried
gsettings set com.canonical.desktop.interface scrollbar-mode normal
but no luck.
Edit this file /usr/share/themes/Ambiance/gtk-3.0/gtk-widgets.css
Look for this line (around line 1200): -GtkRange-slider-width: 10;
And change 10 to a bigger number like 20 or 30, and done :)
I also think they're too small...
See this image:
If you change the scrollbar size to 16 and you want them to stay that way, and not shrink when you don't have the mouse on it, then make the changes in the picture above.
If you use a size other than 16, just experiment with the margin sizes to get it right.
