I’ve been testing KDE 4.14.3 on Korora 21 Beta over the last few days. As Korora 20 had the same version there is little difference between the two. However one change that is noticeable is the new configuration module for Touchpads. Korora 21 is based on Fedora 21 and so most, if not all, of this post applies to Fedora 21 too.
Although laptops and hence touchpads are very common, the options to configure them were very poor in the past. They worked but gave little choice in the set up. With the new module there are many more options for adjusting sensitivity. But there also some new options such as Palm Detection, and disable Touchpad while typing.
Another addition I particularly like is the option to disable the touchpad when a mouse is detected. This works well even with my Bluetooth mouse. There is even the option to ignore any detected advice. I guess this is for devices that may be incorrectly detected as a mouse.
KDE 4.14.3 may be one of the last versions of KDE4 as KDE’s Plasma 5 is out and will ultimately take KDE4’s place but for now the current version is great desktop.
