So, I am changing the scroll speed in Ubuntu using this answer:
Change mouse wheel scroll speed in Chrome on 12.04 (edit starter bar commandline)
Exec=/opt/google/chrome/google-chrome --scroll-pixels=150 %U
It works, but every time Chrome updates I need to do it again, is there any way I can permanently fix this issue?
touchpad_toggle.shimwheel in Wayland to fix the mouse scroll speed for all programs! In Wayland, imwheel works to fix the Chrome scroll speed, but it cannot fix other programs' scroll speed, such as in Sublime Text. See other problems with Wayland in my answer here: Wayland window manager causes my computer to stay on a black/blank screen.imwheel to properly fix the mouse scroll speed for any and all programs you see fit!mouse-scroll-wheel-acceleration-userspace, which I need to mess with more and maybe duplicate in Python myself. His readme is excellent! His tool uses the Python pynput library, which I need to play with and try out myself.
pynput works only partially in Wayland, but fully in X11. See my notes and test code here: https://github.com/albertz/mouse-scroll-wheel-acceleration-userspace/issues/8#issuecomment-1575389079First off, change your Window manager to use X11 instead of Wayland. In short, log out, click your name, click the gear in the bottom-right, choose the non-Wayland window manager option. For details and screenshots, see my other answer here: Wayland window manager causes my computer to stay on a black/blank screen.
Then, run these commands in a terminal:
# 1. Install the imwheel dependency
sudo apt update
sudo apt install imwheel
# 2. Install my configuration file
# Get my whole repo, and symlink the .imwheelrc config
# file to your home dir
git clone https://github.com/ElectricRCAircraftGuy/eRCaGuy_dotfiles.git
cd eRCaGuy_dotfiles/home
ln -si "${PWD}/.imwheelrc" ~
# 3. Get my touchpad toggle script too
mkdir -p ~/bin
cd ../useful_scripts
ln -si "${PWD}/touchpad_toggle.sh" ~/bin/gs_touchpad_toggle
# re-source your ~/.profile bash profile to automatically add ~/bin to your PATH
. ~/.profile
# 4. test it
# Note: if the imwheel mouse scroll speed settings don't properly toggle, first
# log out of Ubuntu and log back in, or reboot, and they should work now.
gs_touchpad_toggle # toggle touchpad off, and imwheel on
gs_touchpad_toggle # toggle touchpad back on again, and imwheel back off
Now follow my instructions (originally from the top of the touchpad_toggle.sh file) to disable the touchpad at boot, and to add the Ctrl + Alt + P shortcut to toggle the touchpad on and off:
Ctrl + Alt + P with the touchpad toggle script.
gs_touchpad_toggle --off for the "Command", and "found in ~/bin" for the "Comment." Click "Add" to save this new entry, then "Close".imwheel to be disabled whenever the touchpad is enabled is because it interferes with the scrolling ability of the touchpad otherwise, breaking two-finger touchpad scrolling. So, the idea is that when the touchpad is disabled, you should use your external mouse, and its scroll wheel should work well, and when the touchpad is enabled, you should use your touchpad, and two-finger touchpad scrolling should work well.(Try this to gain more insight, or if you need to try to manually fix things if the above steps don't work).
Here is a solution which works perfectly (tested recently in Ubuntu 14.04, 18.04, and 20.04):
sudo apt update
sudo apt install imwheel
gedit ~/.imwheelrc
Copy and paste the following into the newly-created .imwheelrc file (that you just made in your home directory via the gedit command above):
".*-chrome*"
None, Up, Button4, 3
None, Down, Button5, 3
Control_L, Up, Control_L|Button4
Control_L, Down, Control_L|Button5
Shift_L, Up, Shift_L|Button4
Shift_L, Down, Shift_L|Button5
3 is the "scroll speed multiplier." Use a larger number for faster scrolling, or a smaller number for slower scrolling. The ".*-chrome*" part says to apply these scroll wheel speed increase changes ONLY to chrome.
Run imwheel -b "4 5" to test your settings. When done testing, run killall imwheel to kill it, then make your edits to .imwheelrc, as desired, and run imwheel -b "4 5" again for more testing. Be sure to fully close and re-open Chrome each time you restart imwheel too, to ensure its new settings take effect. This must be done by right-clicking the little Chrome icon in the top-right of your desktop pane and going to "Exit".
Also keep in mind that if you are using a cheap mouse, your scroll wheel decoder may be lousy and miss encoder counts when moving the wheel fast. Therefore, in such a case, move the wheel at a reduced speed when testing the effect of imwheel, so that your mouse doesn't miss encoder counts on the scroll wheel, making you think imwheel isn't working right when it's really just your cheap hardware's problem.
Add imwheel -b "4 5" to Ubuntu's "Startup Applications" to get it to run every time the computer starts.
As Steven C. Howell says here:
Note that using the option
-b "4 5"restricts imwheel to only affect the scroll wheel, discussed here.
Another answer by "tvn" here: https://askubuntu.com/a/304653/327339.
More answers here: Increase mouse wheel scroll speed.
I am not the original author of the answers linked-to above, rather, user "tvn" and others are, although tvn's answer is lacking in that it replaces mouse scroll wheel movements with multiple arrow-key Arrow Up and Arrow Down key presses, which means you have to click in a window for it to take effect, and some things like the browser-based Jupyter Notebook Python programming environment scroll horribly like this! Therefore, Steven C. Howell gave an improved answer which keeps the scroll wheel mapping to the scroll wheel, instead of to keyboard up and down keys, but his answer is lacking in that it applies this new scroll wheel scaling to everything on your computer, so I just modified this answer 27 Aug. 2018 to reflect Steven Howell's answer, but with the addition of adding ".*-chrome*" to the top of the ~/.imwheelrc file so that these new scroll setting apply only to your Chrome browser, which is really what I want. Note also, I have made several significant and important edits and contributions to tvn's answer linked to above, but now I think this answer here is much better, and it's deviated too much from tvn's answer to even attempt to edit his answer further.
Tested in Ubuntu 14.04 LTS.
Update 3 Mar. 2019: tested in Ubuntu 18.04 LTS as well, and it seems the effect takes place immediately in Chrome now each time you run killall imwheel and then imwheel -b "4 5" to test new settings.
Depending on your computer and hardware, the above settings may work best with a mouse with a scroll wheel. On a track pad (again, this may or may not apply to you or your computer) it may make the result very glitchy when trying to do two-finger scrolling on the touch pad. I have a shortcut key (Ctrl + Alt + P) set up to run a script which enables/disables my track pad so I don't bump it while typing and using a mouse, yet so I can still easily enable it for when I don't have a mouse and/or someone else who loves touch pads wants to use my computer. To fix the glitchy scrolling caused by imwheel when using the touchpad, I've just added the following to my script:
When the touchpad is disabled, enable imwheel so my mouse scroll wheel will work well:
imwheel -b "4 5"
When the touchpad is enabled, disable imwheel so my touchpad two-finger scrolling will work well and not be glitchy:
killall imwheel
Doing the above is especially important for my HP Spectre x360 Ultrabook (Model 13-4193nr, and running Ubuntu 18.04), which otherwise has horribly glitchy two-finger touchpad scrolling when imwheel is enabled.
Here is my full touchpad toggle script with those 2 imwheel lines added as described just above:
File "~/bin/toggle_touchpad":
(I keep the latest version updated here: eRCaGuy_dotfiles/.../touchpad_toggle.sh).
#!/bin/bash
# GS_toggle_touchpad.sh
# - toggle the touchpad on and off

read TouchPadDeviceId <<< $( xinput | sed -nre '/TouchPad|Touchpad/s/.*id=([0-9]*).*/\1/p' )
state=$( xinput list-props "$TouchPadDeviceId" | grep "Device Enabled" | grep -o "[01]$" )
echo "TouchPadDeviceId = $TouchPadDeviceId"
echo "state = $state"
if [ "$state" -eq '1' ];then
xinput --disable "$TouchPadDeviceId"
zenity --info --text "Touchpad DISABLED" --timeout=2
imwheel -b "4 5"
else
xinput --enable "$TouchPadDeviceId"
zenity --info --text "Touchpad ENABLED" --timeout=2
killall imwheel
fi
Touchpad toggle script source: Enable/disable touchpad
Now just run toggle_touchpad from the command line, or associate it with a keyboard shortcut like Ctrl + Alt + P like I have.
Up and Down arrow keys. And for changing tabs, I use Ctrl + PageUp and Ctrl + PageDown. The benefit I get with the improved mouse scrolling overall is worth the tradeoff and cost I think.

unfortunately this function is deprecated and removed from Chrome and Chromium. It is not working anymore with the latest versions of Chrome.
https://code.google.com/p/chromium/issues/detail?id=154776
But you can use this quite cool plugin to speed up your scroll speed in Chrome on Linux.
https://chrome.google.com/webstore/detail/chromium-wheel-smooth-scr/khpcanbeojalbkpgpmjpdkjnkfcgfkhb
Try this alternative https://chrome.google.com/webstore/detail/gestures-for-google-chrom/jpkfjicglakibpenojifdiepckckakgk?utm_source=chrome-app-launcher-info-dialog. It has better performance than Chromium Wheel Smooth Scroller
I've created a simple chrome extension called Scroll Speed in which you can set the scroll factor.
Can be found here: https://chrome.google.com/webstore/detail/scroll-speed/mfmhdfkinffhnfhaalnabffcfjgcmdhl
It has much better performance than the "smooth scroll" extensions I've tried to fix this problem.
After trying for several different plugins to get around this issue with linux chrome extension: AutoScroll, which does not solve the speed issue but offers a way to use the middle key to increase the scrolling speed while preserving a smooth experience.
--scroll-pixelsflag is gone since 2013. See issue #154776
