I took a look at the log files you put on your web site (which are useful), and it looks like XFree86 itself is crashing. FYI, as far as signal 11, aka segmentation faults... Linux uses a feature found in most modern CPUs called protected memory. Each program (including KDE's programs and XFree86) running in Linux is allocated it's own memory space. The program can do whatever it wants in it's memory space, but is forbidden from stepping outside it's memory space, or segment (I'm oversimplifying, but hear me out.) Sometimes, due to bugs, a program tries to illegally access a memory address outside it's allocated area. The CPU and kernel will catch the the program and terminate it with extreme prejudice, leaving you with a segmentation fault error. This is a Good Thing, because if a program was allowed to address memory outside of it's allocated area, it could scribble all over other programs or the kernel itself, which could crash your entire system. Now, as to why XFree86 is crashing... You've already had problems with the nvidia drivers, so you switched to the vesa drivers. According to the XFree86.0.log file, it crashed soon after you try to load OpenGL related stuff, which won't work very well because the vesa drivers won't give you hardware-accelerated 3-d. Things to try: Comment out or remove the lines 'Load "GLcore"' and 'Load "glx"' under Section "Module" in your XF86Config-4. OpenGL will be dog slow without NVidia's accelerated drivers anyways, so if you won't be using them, get rid of them. Without them, OpenGL programs probably won't work at all. You may also want to uninstall nvidia's glx drivers (the nvidia-glx package) so the system goes back to using the generic glx libraries. Another alternative if you want accelerated 3-D for games and such is to get the nvidia drivers working, which is definitely tricky, but may solve your segfault problems. It requires compiling and installing nvidia's kernel driver (and it looks like you already have nvidia's glx libraries which may be trying to do their thing but can't talk to the nvidia driver). Let us know what happens. If you want to get nvidia's driver working, let me know. I've had to wrestle with them a couple times (though in sid, not woody), so I might be able to help you get them working. Doug
