I want to increase the mouse wheel scroll speed in Google Chrome on Ubuntu 12.04.
I've read How can I change the mouse's wheel scroll rate?, I'm on Unity though, how can I edit the commandline for the Chrome icon in the starter bar?
The .desktop files you are looking for are stored in /usr/share/applications/
and then go the 'Desktop Entry' section and look for following line (mine is on line 108):
and change it to (you can use any value you like instead of 150):
Hint: if you use Chromium instead of Google Chrome, edit the chromium-browser.desktop file ;)
The Chromium Wheel Smooth Scroller extension gives you fine-grained control over how your mouse wheel and keyboard perform scrolling.
This appears to be the best bet until the Chrome developers restore smooth-scrolling and configurability again.
