    Spend some time with valgrind, you'll be terrified. Stable vanilla KDE will crawl and segfault at logout, lack of responsivity however can be attributed to the Xorg's stack and the method Qt utilizes to render stuff. Problems are right there, but people just accept the way things are and convince themselves that there's nothing wrong. Much like I don't need audio on Linux, hardware mixing, or who cares about OpenGL 3.2 compliant 3D rendering API.

      I didn't have such a problem with nautilus and yes I find Dolphin faster.

      One thing I miss in KDE is an easy switch user plugin. My 60 years old father has real problem when need to go to menu and then hit the switch user button to find himself before a list of half a dozen users (that thing shows the command line logged users as well and that sucks) and when finally he hits the correct button (prey he didn't hit the console user by mistake) he finds himself before a locked session and needs to unlock it (even if his acount is passwordless). Why the hell the locked sessions are enabled by default and where is the option to change it? With Gnome I had a nice face/button on his panel and with a click he got just the graphically logged users, without stupid locked screens.

        I have disabled this "semantic desktop" thingy though ("-semantic-desktop" in make.conf). Might have something to do with it.
        Hmmm I have it. I will try without it when I install 4.3.4.
        But it's a nice feature... isn't it?

          I don't have a use for it. I know where my files are, I don't need to index them :P

            Now if only Qt would replace Gtk as the standard widget toolkit, then KDE would be perfect.

            Even with qtcurve, Gtk apps look a little funny.

              Whoa, I have no problems with this in Arch. What KDE and QT versions do you use?

              http://my.opera.com/sebt/blog/2008/1...se-11-1-on-t61

              Maybe nvidia related?

              Could you try with nv or vesa?

                They'll say there's something broken. You're trolling attidude is very funny. Btw. if KDE would be such broken in Kubuntu, OpenSuse etc. you're free to blame those distros, but if it works there and doesn't work in your distro you should blame your distro.

                It works great in Arch and Kubuntu (afaik they even speeded up its load time in (K)).

                  Well, it's performance is far better then thing called Gnome, QT4 apps are far more usefull and its code is not leaking. In example Koffice Kword is about 25MB in RAM on 64bit system. I believe nobody's interested in such comments, because of your offendend pride.

                  Gimp is unusable in composited environment, but Krita is much better. Gtk is since ages, but such new toolkit like QT4 is much better accelerated! Or Gtk is just so increadibly slow or broken.

                  Btw. what if they improve performance by 1.499x?

                    Oh, great, more QT FUD. Or do you have proof for this?

                    Because, I am using Gimp with Compiz on fglrx and nvidia drivers, as well as on win32 (also composited) and it runs great on all configurations.

                      I can record you my desktop while painting in Gimp and Krita.

                      EDIT:

                      Forget about those two - it depends on brush size.

                      I had nvidia card and it never ran great, the same about fglrx. I'm using os Ati driver and it's still slow, but it's easier to notice when you turn your CPU to powersave mode. Then move your mous from File to Help dialog in Firefox and notice how slow it is (no matter if composition is turned on or off).

                      Some old, but interesting benchmark (Qt4.3 vs Cairo):

                        I can not see a distinction between Firefox and the QT apps in my desktop.

                          Thanks, this was a pretty interesting read. However, I'm not sure the results are valid as far as Gimp is concerned:
                          • Gimp doesn't really use polygon rendering (maybe the selection tool, but that's it)
                          • This article is from 2006 and the article mentions that Cairo would include the same polygon tesselation algorithm as Qt in some future version.

                          In Gimp, I generally start seeing some performance degradation once I hit the 4096x4096 mark, but anything under that and even my dog-slow NVS135M runs pretty much fine. On high resolutions enabling Gegl can make the difference between taking a coffee break and realtime preview when applying filters (but this part has little to do with Qt vs GTK).

                          I would love to test krita, but it seems to be part of the koffice suite and has a crazy number of dependencies and my SSD wouldn't really like that...

                          Edit: Zack Rusin just plain rocks, though!

                            Try this :
                            http://www.kde-look.org/content/show...content=103741

                            It's still not perfect (thank you gtk+ for not carrying about anything that's not gnome) but IMHO better then qtcurve. Works great for mkvtoolnix and gimp (the only gtk+ apps I use)

                              Like I said forget about Gimp and Krita, because both are slow when I choose bigger brush size and when I have compositing enabled

                                I, and many more people out there, don't have this kind of problem since KDE 4.2 and newer X.org, Kernel, or other parts of the system.

                                In fact, my intel Atom with the 950GMA "GPU" consumes less than 150MB of memory after KDE 4.3 log-in. Problems WHERE right there, and they've been adressed by many dowstream projects. Obviously there are many obstacles and not every bit is perfect. My Athlon 64 939 with an Ge Force 7600 consumes much more memory at log-in than the Atom one.

                                My Creative X-fi do Hardware Mixing with Alsa. I don't even bother with pulseaudio, phonon or whatever. It Just Mixes®

                                And by the way... nvidia already cares about OpenGL 3.2. Gallium 3D too. But it takes time.
