Re: kde applications signal 11
Hi there.
I had the same problem. The cause was that I had a half-finished
install of the Nvidia GPU drivers, and glx (the module Nvidia uses to
"talk 3D" to X) was conflicting with the OpenGL and dri modules, thus
not loading and making *all* of KDE's apps to cry on exit. I don't have
what have KDE's apps to do with glx,thogh...
The cure was to remove the GLcore and dri modules from
/etc/X11/XF86Config-4, glx was already there, and to change my vide
cards driver from nv to nvidia. After an X restart, I had glx at last.
If you have the Nvidia GPU drivers onboard, but *don't* see the Nvidia
logo when X starts (and have not dehabilitated it yourself), then most
probably you have the same issue. Either remove glx from your
XF86Config-4, or finish the driver installation.
To know what is your problem, check your ~/.xsession-errors. An excerpt
from mine:
KCrash: Application 'kcminit' crashing...
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Every crash (except 1 or 2 "normal" ones) had the GLX error. And
indeed, running glxinfo would state, more wildly than clearly, that I
had not glx. The next step was to check current X log:
> $ grep -i glx /var/log/XFree86.0.log
(II) LoadModule: "glx"
(II) Loading /usr/X11R6/lib/modules/extensions/libglx.so
(II) Module glx: vendor="NVIDIA Corporation"
(II) Loading extension GLX

/usr/X11R6/lib/modules/extensions/libdri.a is unresolved!
(EE) Failed to initialize GLX extension (NVIDIA X driver not found)
(EE) Failed to initialize GLX extension (NVIDIA X driver not found)
So, indeeded, glx couln't load becouse an unresolved glx symbol in a dri
library. That ringed some bells from the last time I installed the
driver completely by hand; that time I had to disable some modules from
X, included dri. I was installing a 2.6 box, so I had compiled
nvidia-kernel-source by hand and installed the resulting package plus
nvidia-common and nvidia-glx, so I had chomped the nvidia-kernel's
readme, but not glx's one. There are specified the needed modifications
to XF86Config-4: remove GLcore and dri, add glx, change nv to nvidia.
The strange things are KDE apps crying for glx when closing, and
XF86Config-4 loading glx *and* GLcore/dri without my intervention.
Posible bugs?

Hi,
I'm trying to determine if I have a bug and where I should report it to.
I'm running debian testing, with kde as my desktop.
Whenever I close an application which is from kde, I get this error
message:
"The application unknown (konsole) crashed and caused the signal 11
(SIGSEGV)."
Of course, this message was generated by closing konsole, but closing just
about any application from kde causes an error. The error window says it
can do a backtrace, but when I try it, it says the backtrace is useless.
Processes which are not from kde packages do not cause this error
> message, for example synaptic.
thanks,
Maurice
