Scroll, then press ctrl = zoom #10587

 * Cinnamon version 5.0.7
 * Mint 20.2

Whenever I scroll up in any window and then press ctrl, I zoom in. The contrary happens when I scroll down and then hit ctrl: I zoom out.

This can be annoying when I want to scroll up and then open a new window with ctrl+n, or in fact do anything involving ctrl after scrolling.

I'm sorry if this is not cinnamon's fault. It it is not, please tell me where to go with this problem.

Can't confirm this on a Mint with the same Cinnamon I'm running in Virtualbox.

But I tried with left Ctrl since right Ctrl is a vb special key.

BraveSentry commented 2 years ago

I used left ctrl too. To give some examples of where I found this: Firefox (across several versions), Nemo, Thunderbird (when viewing a mail). It does not happen on chrome - but chrome does not zoom with ctrl+scrolling anyway. I tried some things now (sorry, should have thought about it earlier) and found out that it happens only with 2-finger-scrolling on my trackpad, not with a mouse wheel, arrow keys or page up/down.

Ah yeah, I tried in Firefox with a mouse, don't have a trackpad.

Do you have Desktop Zoom enabled in accessibility settings?

Perhaps you set its modifier to ctrl (it's usually alt to avoid interfering with zoomable apps that use ctrl). image

Nope. I switched it on out of curiosity, the modifier was alt. Now I switched it back off.

If this is trackpad specific, you are probably using the synaptics xinput driver, which has scroll "Coasting" enabled by default.

If you want to disable this, set CoastingSpeed to 0 using synclient or in your xorg configuration file for the synaptics configuration. https://wiki.archlinux.org/title/Touchpad_Synaptics (file paths, package manager, etc, will depend on which distro you're using)

Thanks a lot. This was it. It's a trade off though: Do I live with this minor bug to have dynamic scrolling, or do I want the bug gone but have to scroll without coasting. Anyway, thanks nonetheless!
