    Phoronix: KDE 4.3.0 RC2 Brings Fewer Changes

    Just a week after the release of the KDE 4.3 release candidate, a second release candidate has emerged from the Gran Canaria Desktop Summit. KDE 4.3 Release Candidate 2 incorporates fewer changes than earlier development releases, as development winds down for the final release of KDE 4.3.0 later this month. The KDE 4.3.0 RC2 announcement can be read at KDE.org...

    I've built it, installed it. It still sucks, and there are no performance improvements.

      If you dont have GPU accelerated desktop you will never see performance improvements, if you do, it is faster than gnome/gtk.

      And just trolling wont help, what does "suck"?

        Of course I do, did you expect me to use QT on fbdev without Xorg? The quality of code sucks, it is ("mind-bogglingly slow") with huge footprint.

          I use Qt on xfbdev (on netbook) and I get 4 time more FPS than GTK apps because Qt can redraw only part of the windows and instead of the whole screen like Gtk. Clutter can do that, but can't work on fbdev (but nobody care about fbdev anyway).

          You just have to use xfbdev instead of fbdev (the port to fbdev is dead), it will load as fast, use as much memory and Qt will be 4 time faster than GTK.

          But about the speed, just enable GPU windows drawing, if it is slower than gnome, then it is your fault, not KDE. If you talk about resize speed, it is because KDE3 and Gnome use an hack to send more redraw event to windows, Qt4 does not support the hack (but 4.6 will) making it seem slower, while it is only because the WM send less request.

          Qt code quality is exelent, Object oriented code is cleaner than C (it is almost the only good point I can find to OOP). GTK/GnomeLib use some object oriented C, it is messy and hacky. Qt is not a UI toolkit, it is a programming framework with almost every feature you can expect from one.

            Neat, I will try it ASAP .

              I just pulled the packages in from the Kubuntu backports. It seems the plasma segfault is gone. Now I can finally move to kde 4.3 (from gnome)

                If I remember you own a nVidia card. There are some hacks on their unofficial forum to improve performance. Some time ago using vesa KDE 4 was smoother then using their drivers, so low performance can be nVidia fault.

                  Not anymore. If you are using driver 180.xx or later, especially with GeForce 8 class hardware or higher, performance has improved drastically.

                    Plasma is still locking up on me

                      Did you try to start with a new configuration.

                      Rename your ~/.kde to ~/.kde_back

                      and try again to start you kde.
                      Of course you will have a clean config but it's just to test if you have less troubles.

                      If it's the case you can always restore folder by folder what you want.
                      share/apps etc...

                        At first glance, my problems seem to apparmor related. Disabling it seems to be the cure-all.

                          Nice to hear it, were you able to report the bug ?
                          I think it's the most difficult at this time, we have to install a lot of packages to be able to report a crash, I really hope they will simplify the system as soon as possible.

                            I was never able to pin it down. Plus, had an additional plasma freeze later. My taskbar becomes unresponsive while some windows are fine. Eventually, it all craters.

                            Running with a clean config now. We'll see how that goes.

                              Really strange, I had some plasma crashes on RC1 but not that much and the Bug window always poped up immediatly so I could just clic on restart application.

                              So not that much annoying considering it's a RC version.

                              Anyway I hope the clean config will help you, because I won't leave KDE for nothing, the applications and the usability of the UI is just awesome. It really fits what I need.
                              With some few missing things (exemple settings-> keyboard,mouse (under there you can adjust your joystick too.. even if it's not on title...) ) there is no DEADZONE config... !

                              Or I have two screens and when I do a mouse over on the folder view plasmoid the popup with sub folders appear on my main screen and not on the screen where I'm doing the mouse over.

                              Well I really think they are on good way. If you still have troubles with KDE, shall you go report them on their site.

                              See ya
