Can you please post/attach glxinfo output? Forgive my inexperience with KDE, I only use it to check for gross errors... Anyway on my system, I go to System Settings/Desktop Effects/Advanced/Compositing Type, and there I can still switch between XRender and OpenGL. Have you looked through .xsession-errors? glxinfo is another likely candidate, as is xdpyinfo.

I can switch allright, the tough part is applying the changes. ;-) Anyway, as requested I shall add the output of glxinfo, xdpyinfo and .xsession-error. The latter shows a complete session of bringing up the xserver, logging on, and trying to switch on desktop effects from within "system settings". Created attachment 36568 [details]

Xsession Errors
The difference seems to be: kwin(3910): Compositing self-check failed, disabling compositing. I have no idea what the self-check is nor how it fails from the log. Martin, can you try any other modern distro other than Slackware? Like, e.g. Fedora 13? I smell something fishy with your setup. Like: 1) You have a custom probably broken X.org configuration (you'd better try running without it) 2) You have impossible options in KWin (try creating a new user and logging into it) If it doesn't still help, please, look here: http://techbase.kde.org/Projects/KWin/4.0-release-notes#Setting_up http://websvn.kde.org/*checkout*/trunk/KDE/kdebase/workspace/kwin/COMPOSITE_HOWTO P.S. This bug doesn't belong here, please repost it to https://bugs.kde.org/ (but mind that the first you'll be suggested is to upgrade to KDE 4.4.4).

I then proceeded to remove ~/.kde/share/config/kwinrc for the old user, and managed to enable desktop effects after the logon. I have saved the old kwinrc. I shall attach the diff in case anyone wants to study the difference between old and new, and why it works for 2.11.901 but not for 2.12.0. Other than that, I think the case is closed. Thanks for the pointers. Martin Created attachment 36581 [details]
Kwinrc Diff
Closing, I would prefer to know exactly what KDE was doing that it decided no longer worked, but too many bugs, too little time. |
