Version: (using KDE 3.5.8) Installed from: Debian stable Packages OS: Linux Under different Linux versions (Debian from 2006, Knoppix 4 .. 5.3) and KDE 3.5x it's impossible to change the mouse operation to left hand. I tried it via control panel or with variation of the parameters of the mouse changing command in the terminal window. The behavior changed a little bit but the only necessary changing between left and right button doesn't appear. I tested it with PS/2 and USB mouse. Sometimes I had the impression - after switching to left hand mode - only to have two secondary buttons. In some discussion forums I found hints and workarounds but nothing solves the problem.
There are several left-handed people in my family, this might help convince them to try Linux, no other OS does this :-)
Hello! Sorry to be the bearer of bad news, but this project has been unmaintained for many years so I am closing this bug. Kcontrol has been replaced by System Settings in Plasma. Please give the latest version of that a try, and open a new bug in "systemsettings" if you continue to have an issue. Thank you!
