God help me, I've set up Gnome3 (Fedora 21) in a virtualbox to try to do some development work. Could somebody tell me what idiot designed these skinny-arse scrollbars and how I can fix it?

Hi,

are you saying you want wider scroll bars? Or perhaps that you don't want any scroll bars? Either of these could likely be achieved using a different theme. Are scroll bars something integral to your development work?

Evo2.

Just the scroll bars for anything. Web browser, file manager, pdf reader. I don't mind losing the extra 10 pixels of screen width if it means not getting a headache trying to pinpoint my mouse on these things.

probably you will find some tips here: http://askubuntu.com/questions/78937...in-gnome-shell

Hi,

These all likely gtk3 programs, so you can change how they look (including the scroll bars) by changing the gtk3 theme.
Ok. I generally do't use scroll bars since I find it easier to scroll with the key board (eg Shift-PgDn or just PgDn etc.) or with a touchpad (when using a laptop).

Evo2.

The first 2 solutions were out of it because it's not just firefox, it's right across the board.
As per the 3rd suggestion, I changed the GtkScrollbar::slider-width setting in /usr/share/themes/Adwaita/gtk-2.0/gtkrc to no effect and the only file in /usr/share/themes/Adwaita/gtk-3.0/ is gtk.css which has the one line: /* Adwaita is the default theme of GTK+ 3, this file is not used */
I've also installed tweak-tool but nothing there.
Edit: Tried to change the overall theme, I guess "Appearance' in gnome-tweak is the only place I can find to do it. 'Shell Theme' is disabled and 'GTK+' has only choice of Adwaita or HighContrast even though /use/share/themes has Anaconda and Raleigh listed.

Anyway, thanks for the help, f it, I quit.
