Window Managers Gtk+ has GNOME on the one hand, and Xfce on the other. Qt, on the other hand, only has KDE - there's no lightweight, less encompassing alternative if KDE doesn't float your boat, but you'd still want a Qt desktop. Luckily for you, there's now Razor-qt, a small, lightweight and simple Qt desktop environment.

How is this inaccurate ?

http://labs.qt.nokia.com/2011/05/09/thoughts-about-qt-5/

A working OpenGL implementation will be required for Qt 5+ software to run. Knowing the fantastic performance of software OpenGL emulation and the new focus on shiny animations and touchscreen gestures, it is likely that a GPU with working drivers will be required for future Qt software to run properly. Fun times for Linux users with recent graphics hardware...

This article also explicitly states that QML + Javascript is the future, and that they expect you to only use C++ for application logic, or even not at all.

I am the first to hope that this madness will cease before it has gone too far, as I like Qt 4 as a framework and it saddens me to see it take that direction.

Well the good thing about the new open source governance for qt5 is if enough people agree with you, a consensus should be able to ensure qml-declarative doesn't entirely dominate the direction.

Nokia still pays alot of committer salaries though :|

I have seen Qt5 run on top of Mesa software rendering, and the performance is great.

Including when tapping into Qt's new animation capabilities ?

I know that the QML demos of Qt 4.7 are somewhat sluggish on the Fedora 15 install of my laptop, which offers a typical example of imperfect GPU support (Dual-GPU setup in which the Intel chip works reasonably well and the NVidia chip doesn't).

My problem with that is that as outdated as pre-Sandy Bridge Intel GPUs may be, I believe they still vastly outperform Mesa OpenGL emulation on CPUs for the same period. If you know of a simple way to temporarily disable GPU acceleration on Linux, I can experimentally test this belief.

So, unless Qt 5 has vastly improved rendering performance over Qt 4, what will happen when developers will start to put pretty animated transitions everywhere in their software, as is somewhat encouraged by the QML part of the Qt SDK ?
