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?

  • Maybe use an extension? Feb 12, 2013 at 20:50

  • You can set permissions to the desktop file to read-only. Aug 28, 2018 at 6:28
  • @MichalPrzybylowicz, that doesn't stop people from launching chrome without the parameter via terminal or Alt+F2

  • Note: the --scroll-pixels flag is gone since 2013. See issue #154776

Update 2020: just use this script from my repo here and be done: eRCaGuy_dotfiles...touchpad_toggle.sh

Original answer:

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):

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.

Reference notes:

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.

Help, my touchpad/trackpad is glitchy when scrolling!

  • This section added 22 June 2019:

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).


# GS_toggle_touchpad.sh

# Search for id number of "TouchPad" OR "Touchpad" in `xinput` list; manually type `xinput` to see all your devices
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"
    xinput --enable "$TouchPadDeviceId"
    zenity --info --text "Touchpad ENABLED" --timeout=2
    killall imwheel

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.


  1. Get the latest version of this script from my repo here! eRCaGuy_dotfiles...touchpad_toggle.sh
  2. Enable/disable touchpad

Known bugs/issues:

  • [AMAZON PLEASE FIX THIS!] Amazon designed their website with your discomfort in mind, and their website is extremely slow and glitchy when using the above fix. I haven't noticed a single issue with this fix except on Amazon.com. So, when using Amazon, you might want to just use Firefox, or temporarily disable imwheel with the Ctrl + Alt + P shortcut I helped you set up above.
    • Amazon, why are you so lousy?
    • Note: the behavior is that after scrolling with the mouse wheel on Amazon.com, while imwheel is enabled, you may see:
      1. you cannot click on any links for a few seconds after you stop scrolling
      2. images take a long time to load
      3. CPU usage on Amazon webpages is extremely high. See the Chrome Task Manager to see tabs or pages using lots of CPU time. Open the Chrome Task Manager with Shift + Esc, or by going to the 3 dots in the top-right of Chrome --> "More tools" --> "Task manager".
  • imwheel emulates multiple scroll messages. But that totally breaks scrolling through tabs. Now I can't scroll to any tab, I scroll through 4 tabs at a time.

  • This is true. For fine-tuned vertical scrolling, I use the 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. Jul 16, 2020 at 3:02
  • Hopefully Chrome gives us some scroll speed/resolution/distance settings in the future, but for now, this is what works best for me by far. You might consider making requests through Google to add scroll settings into Chrome, though, so we wouldn't need to hack it anymore. Jul 16, 2020 at 3:02
  • @Trevor, I just found another super simple fix: since I'm applying the imwheel increased scroll speed to Chrome only, simply removing focus from the Chrome window and then hovering over the tabs and using the mouse scroll wheel works too. This is easy if you have two monitors: just click on a window on the other monitor, then when you hover over the Chrome tabs & scroll, since the chrome window isn't in focus, it applies the normal 1-tab per tick scroll. Once you click on the Chrome window, it gets focus, & now you'll get the imwheel-adjusted increased scroll, skipping some tabs as you scroll. Aug 7, 2020 at 18:29
  • Works great for legacy systems running X11 but nothing modern running Wayland

unfortunately this function is deprecated and removed from Chrome and Chromium. It is not working anymore with the latest versions of Chrome.


But you can use this quite cool plugin to speed up your scroll speed in Chrome on Linux.

    The performance of the plugin is not so good. The speed is erratic.

    Try the Smooth Scroll extension, it should work better.

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

  • This has been fixed in chrome for a while now Dec 4, 2016 at 18:38
  • @get-off-my-lawn could you provide better alternative?

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.
