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

[interzoneuk]

Hi.

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 ...windows 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...
