() from /usr/lib/kde4/libkdeinit/libkdeinit4_kwin.so Unfortunately the relevant libraries are stripped. a) Can you compile with debug enabled? b) The backtrace ends in fglxr and is most likely a driver issue. c) it might only occur on the very first execution after booting (undefined state in the driver), pot. it re-occurs after logging out and back in. Do you force direct GL? If not you can *try* exporting KWIN_DIRECT_GL=1 temporarily run KWIN_DIRECT_GL=1 kwin --replace & for long time setting, add an *executable* shell script to ~/.kde/env -------- snip force_dri.sh ------------ #!/bin/sh export KWIN_DIRECT_GL=1 -------- /snip force_dri.sh ------------ DRI with fglrx used to fail but latter reports suggest it meanwhile works (better than indirect rendering)
Thomas, i'm sorry for missing backtraces, drkonqi fooled me with it's 3 little stars, i didn't noticed i don't have kde-workspace debug package installed, and backtraces anyway look like hieroglyphs to me :) (other than library names). So far i didn't manage trigger the crash, and i am not forcing direct rendering, these newer, "better" working drivers don't cover my hardware anymore, and lately fglrx has been behaving pretty good (no crashes for a long time, until this one). Do you have any idea what could trigger the crash? (If that does mean anything, systemsettings window was maximized.)
(In reply to comment #2) > Do you have any idea what could trigger the crash? (If that does mean > anything, systemsettings window was maximized.) Nope, sorry - not w/o a backtrace ;-) However the xio error seems to be usually caused by some installation issues, remaining mesa installation, whatever - esp. ensure you ran "/usr/bin/aticonfig --initial"
I'll close this for now, cause can't get the crash anymore.
