Can confirm this on a Lenovo S400 touch running Kubuntu 12.04 up to 14.04. I cannot work with widgets or my single tap on touchscreen will register as hover. Single taps will still work in some applications, but not on panel. Also, since 12.04, most dropdown menus never work with the touchscreen. If they appear at all, they disappear immediatly. After upgrade last night which updated chrome and firefox, I now have occasional issues with the single tap function in my browsers. When I launch Firefox, the single tap becomes hover (sometimes) and doesn't return for some time. During that time, it affects the whole system.
Please note I have installed touchegg and have found that, while it adds the ability to customize gestures, it does absolutely nothing to help any of these issues. The problem remains even when using xinput to calibrate.
I praise the Linux communites all the time for their timely response in updating with fixes to bugs like these, and I rarely complain about Linux bugs, because I understand that, in using Kubuntu, I am recieving something awesome at no cost! However, as the size of this thread indicates, these touchscreen bugs are a nuisance, and have been present and reproducible in Kubuntu since at least 12.04. And as someone mentioned above, they are still present in KDE 5. This issue has been a longstanding thorn in Kubuntu's side, and in the sides of its users. It's time to address it, or at least tell us that it's being addressed. Sorry, I appreciate this community, but I don't understand why KDE 5 is a focus when important issues like this haven't been addressed since at least 2012. Priorities seem skewed here.
