I am going to close this old thread now
]]>Sorry, I shouldn't have posted that firefox screenshot. What I meant was that GTK applications are not themed as well. However, the main issue here is that there seems to be no theming at all, e.g., oxygen is not available for Qt applications (only built-in styles selectable, as shown in the first screenshot).
I had the same problem. It seems that KDE ignores the "old" oxygen.so file. Moving /usr/lib/kde4/plugins/styles/oxygen.so to /usr/lib/kde4/plugins/styles/oxygen2.so solved it for me - however, it is only a workaround for that strange problem.
I have just tried to symlink the oxygen.so file to oxygen2.so, but unfortunately that hasn't changed anything.
additional info: I did a fresh install of the system on wednesday with KDE 4.8.0. I didn't have any problems with oxygen or theming back then. I also tried removing ~/.kde4.
EDIT: note that I'm in a full KDE session and QT_PLUGIN_PATH is set to $HOME/.kde4/lib/kde4/plugins/:/usr/lib/kde4/plugins/
EDIT2: I just reported it as a bug -- https://bugs.archlinux.org/index.php?do … k_id=28838
EDIT3: It turned out it is indeed a configuration error. To anyone having this issue: delete ~/.config/Trolltech.conf
]]>(I'm was not sure where to place this thread so please forgive me if I should have placed in somewhere else :-))
Today I upgraded my KDE to 4.8.1 and now I'm missing the Oxygen widget style. I tried reinstalling kdebase and kde-workspace and I even uninstalled all of kde, followed by installing kde-meta (previously I had the "kde" package installed).
Since there is no "oxygen" package (or at least I couldn't find it) I'm really stuck here. I also couldn't find anything related in the forums, like issues from previous upgrades.
I made two screenshots. At [1] you see that only unthemed widget styles are available. At [2] you see that also GTK apps like firefox have lost their theming although oxygen-gtk is installed.
I'd appreciate any help!
cheers
