Customize the number of lines that are scrolled...

TsunamiZ

Please add an option to let us customize the number of lines that are scrolled for each notch that the mouse wheel is rotated, independently of the host system settings.

[bug reported VB-53764]

@TsunamiZ thanks for sharing this request. I moved it to the settings subcategory cause that's where it belongs.

Is there a way to set a higher number of lines to scroll?
I am using Ubuntu 19.04 with a usually mouse with scroll wheel. It only scrolles 2 or 3 lines.
In Firefox or LibreOffice scrolling is faster.

Isn't this an OS setting? In Windows mouse settings:

In GNU/Linux this feature is even more important.

The problem is, the scroll sensitivity in Vivaldi is to low in Linux by default unlike in Windows and is set accordingly to what is set globally in the system whereas in Windows the scroll sensitivity in Vivaldi is a bit higher that what is set globally in the system. In Windows it scrolls by 4 lines in Vivaldi even though it's set to 3 lines in the system.

What more, you can't control the scroll sensitivity of Vivaldi in Linux for 2 reasons: Your system either uses the newer libinput input driver which has removed the ability to set the scroll sensitivity on the mouse driver level so you can't set it in the system globally. Another situation is when you have the older evdev input driver active for which you can set the scroll sensitivity globally admittedly but it's not respected by Vivaldi only for some reason unknown to me.

There are only partial solutions to this in Linux. You can either install a Chrome extension to Vivaldi which deals in scroll sensitivity, like "Linux Scroll Speed Fix" but it either removes the smooth scroll feature on pages where it modifies the scroll sensitivity for or it doesn't affect the scroll sensitivity at all. Regarding the side panel, the scroll sensitivity isn't affected either.

The other solution in Linux is to run the imwheel application which can map multiple keyboard button pushes to one mouse wheel scroll step and send it to the target window. So you can set it the way that by mouse wheel scrolling imwheel sends multiple UP and DOWN button pushes to a target application like Vivaldi. This can increase the scroll sensitivity for all web pages and even for the side panel while retaining the smooth scroll feature. Unfortunately this breaks tab switching by mouse wheel when the mouse cursor is on the tab bar because it skips multiple tabs by one scroll step due to imwheel sending several cursor button pushes to Vivaldi for one scroll step. Also imwheel doesn't affect the scroll speed for target windows without focus - so it offers no improved scroll sensitivity for Vivaldi partly hidden behing another window which might currentlly have the focus.

So as you can see, scrolling in Vivaldi is quiet a pain on GNU/Linux and thus it needs the scroll sensitivity or number-of-lines-per-scroll-step option very much.

Some mouse settings are in vivaldi://flags/
#smooth-scrolling
and
#percent-based-scrolling (this increased the speed somewhat)
