I just realized I don't know how to set mouse speed in TDE. Control center allows to set acceleration but not speed. I'd like to set acceleration to 1 (default: 2) but then the mouse is a bit too slow, so I need to increase the speed. How can I do that?

Hi Janek, That is actually the speed setting :-) You can set it in steps of 0.1, so if 2 is too fast and 1 is too slow, try a value in between that you are happy with. Cheers Michele

Thanks! (And sorry for late reply)

I wonder whether this is bad Polish localization ("acceleration" used instead of "speed") or is the term acceleration actually used in English TDE as well? I find this confusing, since mouse acceleration means something different to me (variable cursor speed depending on how fast the mosue is actually moved).

In German it's called acceleration as well, and in English, too. Me thinks, it's rather a technical term as one from the users POV. There seems to be a basic speed from the X-window system, which is then "accelerated" by a factor exponentially increased in dependence of the initial speed of mouse movement. I guess one would have to look at the source code for the exact algorithm… ;-)

That's what it actually does, AFAIU. When you move the mouse slowly it is not accelerated as much as when you start to move it with a quick twist of the wrist. Try an acceleration of more than x3 and you will be able to observe this clearly.

The X11 underlying system changed some years ago. Before that, KDE3 and all other DE of that time had accurate settings for speed/acceleration. Now X11 always applies some kind of acceleration depending on your input device. Play around with xinput/xset to get a 1:1 mapping for mousespeed to cursorspeed or touchpoint elongation to cursurspeed. When that's done, the TDE settings work as they sould.

Indeed, that's what the manual pages for xset and xinput say, though they elide the detials of what the acceleration formula is. xinput lists three parameters (accelNum, accelDenom, and threshold) but xset seems to only allow setting the first and the last one. In the end I couldn;t figure out how to get what I want.
And in case someone wonders why I want to have no acceleration and only speed: games. In particular, first-person shooters require making fast and precise movements, but that it is impossible with mouse acceleration. One either gets a precise movement (but then it has to be slow) or a fast movement (but then one loses control of precision).

Here is a screenshot of my mouse-speed settings. This has not changed more than a few ticks one way or another since about 2005 and KDE3.
Works well on a large screen display (1600x900); I want my mouse to feel like my own hand moving, not too slow or fast. And as you can tell, I use mouse keys a lot.
Just for comparison, if anybody can use the reference.

The settings tab, the screenshot you sent, shows the settings related to the mouse movement made using the keys, not the mouse as a separate device.

duh ... ooops! Sorry!

I was just about to get on my high horse and say that you're wrong, but I stand corrected. Enclosed is a screenshot of the proper tab for mouse speed -- *not* for mouse keys. Please see attachment.
(The reason for this mistake, I believe, is that I use the other tab nearly every time I boot up, because I cannot get my mouse key settings to be permanent unless I click-unclick that little box every time.) My mind just tuned out that detail (mouse keys not mouse speed), because I never touch it otherwise.
Bill
P.S. I work on a desktop, by the way. I ought to have specified that detail, too, for what it's worth. My settings might not work so well on a laptop with a touchpad.
Also, isn't acceleration (or deceleration) supposed to be a rate of increase or decrease of speed? not speed itself? It seemed to me that these terms were being used almost interchangeably.

The acceleration setting should be exactly as mentioned next to it in this thread - "acceleration" depending on the length of the movement, not the "speed setting". Therefore, the term "acceleration" should be the correct one.
We can verify what settings are made by this widget to confirm if it is really an acceleration setting.
Cheers

Changes made by the widget are reflected in xinputs --get-feedbacks, so I think it is safe to assume the widget works as expected.

As a follow-up in the discussion it seems like it is possible to set mouse acceleration options (inlcuing the acceleration algorithm) via `/etc/X11/xorg.conf` - see `man 5 xorg.conf`. Unfortunatelly, for whatever reasons these settings (and many ofther xorg.conf settings) seem to be completely ignored.
