    Default gdb help - backtrace for kwin KDE4.04 bug (still present)..


    I have asked this question pretty much all over the internet but have never had a response...

    There is still a very nasty bug in KDE 4 that on some Nvidia cards crashes KDE (and locks up the machine style..)

    - see bug :-

    Bug 157282 - Looking glass magnifer and sharpen OpenGL Desktop effects crash/do not work on multiple systems

    I am unable to use gdb to provide a backtrace, i'm nearly there but must be doing something wrong..

    This is what i am doing

    From console in kde (as root)

    # ps aux | grep kwin (to find kwin pid)

    # gdb kwin (pid)

    - at this point i am unable to click on anything (as kwin is frozen..)

    I turn logging on by

    # set logging on

    I then try to debug by using

    # continue

    - after using continue I can start to use kde (kwin) again, however no more output is created.

    Can someone please point me in the right direction I must be doing something wrong, or even better provide example lines that they would use....

    - i have the debug RPMS's installed...

    Does no one know ?

    Amazingly I have asked this question on about 8 forums, no response..........

    This is STILL a bug in Opensuse 11 (final...) - also with KDE 4.1 beta / alpha...
