Description Chris Wales 2006-06-15 11:16:52 UTC
Version:            (using KDE 3.5.3 Level "a" , unofficial build of SUSE )
Compiler:          Target: x86_64-suse-linux
OS:                Linux (x86_64) release 2.6.16.13-4-smp

I have recently installed a new laser mouse and discovered that even at 1.0x acceleration it moves way too quickly around my screen. Various suggestions Googled involving the editing of Xorg.conf or .xinitrc files completely failed. Is it possible to infact "decelerate" the mouse by changing this option so that one can go below 1.0x speed?

Best,

Chris

I'm not sure how this could be done, since acceleration only kicks in when you move the pointer more than a specified number of pixels per (milli)second - take a look at the whatsthis help for "pointer threshold"
Comment 2 Chris Wales 2006-06-15 21:37:24 UTC
Maybe with some kind of process that does the opposite- reduces the speed of the pointer after you move more than the specified number per millisecond?
Comment 3 Philip Rodrigues 2006-06-16 16:48:34 UTC
Sounds counterintuitive - you move the (physical) mouse faster, and the pointer moves slower? But let's leave the maintainer to comment.

I can confirm this. The optical mouse moves too fast on my screen with acceleration 1.0 and there is no way to decrease it from the Control Center.

I found two solutions that work for me:
1. run `xset m 7/10` everytime I logon into KDE (or put it in a startup script somewhere)
2. manually edit ~/.kde/share/config/kcminputrc to contain the line 'Acceleration=0.7' under [Mouse].

There is a related (older) bug entry: https://bugs.kde.org/show_bug.cgi?id=95928
What does it take for these bugs to get confirmed? (I'm new to bugs.kde.org :)

Thanks for pointing out the dupe. We generally keep wishlist items "UNCONFIRMED" until someone is actually working on them, which is why this one remained "unconfirmed".

Are there any plans to make the mouse acceleration slower?  I have a Razer Copperhead and I've turned down both the acceleration and the threshold to the minimum in kcontrol.  Also, I have the speed on the mouse itself turned to the minimum.  With all that set to the minimum, my mouse still moves around at a pretty good speed; being able to make it move more slowly using kcontrol would be cool.

+1. I had to edit my xorg.conf and add
        Option      "Sensitivity" "0.3"
because the slider in KControl can't go below 1.0.

Whoops. Meant to add this to the open one.
