Hi,

I had a problem a couple of months ago on my laptop (a Dell Latitude E6500) in which after an upgrade of the nvidia drivers (as far as I was able to determine) from*195.36.31-6 to 270.41.06-1 resulted in a problem in which starting any KDE application would cause a traceback and crashing X. I dug on this and didn't find anything online that helped me figure out the problem...So I rebuilt. Everything worked in squeeze with the older drivers. Then, recently, I upgraded to wheezy, and started experiencing the same issue.


I determined that the problem was the xorg.conf that was generated by nvidia-settings to accomodate my dual-monitor setup in the office. If I use a generic xorg.conf only to use the nvidia driver:

Section "Device"

*** Identifier*** "Card"
*** Driver*** *** "nvidia"
EndSection

...everything works fine, albeit without the external monitor. However, if I use the one generated by nvidia-config:

# nvidia-settings: X configuration file generated by nvidia-settings

I didn't see anything obtuse that would cause the type of behavior such as I was seeing. However, I stripped it down as far as I could (e.g. removing the options from the screen sections), I still see the same behavior. Can anyone see what could be causing this strange crashiness?
