KDE "Mobile devices that adapt to who you are, reflecting what you are doing when you are doing it. This concept is at the heart of the Plasma Active user experience. Plasma Active One was released in October 2011, providing early adopters the first opportunity to experience Activities on a tablet. Since then, the design and development team behind this open source touch interface has been hard at work on an update. The fruits of their labor were released today, December 14, 2011 as Plasma Active Two."

Member since:

don't have a problem with non kde-composited elements. Slider elements where the 'blue-shadow' lags behind the actual movement i.e. veromix (mostly the qml-based plasmoids suffer from this, but the 'change activity' plasmoid takes a loooong time to load etc...). I have more than one system running, xfce, gnome 3, razor-qt, but preferably KDE since it is the more usefull desktop. All desktops are speedy, except kde. On all desktops but kde elements pop-up without waiting, both on the open source nvidia as well with the closed binary driver. If I recall correctly, I'm not the only one complaining about performance problems with plasma (and kwin). They're working on it, it clearly improves with every version, however they still have a long way to go when it comes to performance. I have both a performant desktop as a 4 year old laptop (core2duo-nvidia8400m). On the laptop I just had to start using gnome 3 because kde is unbearable there. I really doubt it's the hardware being broken, oh yeah, running 4.7.4, hopefully 4.8 delivers the improvements promised.

Since you are obviously a little slow on the uptake, I will attempt to explain it once again. Just as you see no adverse effects on other desktops, I see no adverse effects on KDE. KDE is not, in and of itself, slow. If it is slow for you on your systems, and it is not slow for me on any of mine, and likewise it is not slow for millions of others on their systems, then the reason why it is slow for you must lie somewhere within your system that is different to all these other systems where KDE is not slow at all.

Given that all the systems in question run the same KDE software, obviously the problem you are experiencing where KDE is sluggish on your system is not a problem of KDE itself. It is a problem somewhere in your system that is not at play in all those other systems which work great with KDE.

I don't say it is your hardware, it is probably somewhere in the underlying layers between your hardware and KDE. The most likely place is in your video driver, the next most likely place is somewhere in Mesa (which implements OpenGL on Linux systems).
