X11 crashes with guest additions (vboxvideo_drv.so)

[Nidif]

Hi,

I'm setting up a fedora guest (Fedora 16-x86_64, Kernel 3.1.0-7) on WindowsXP-64 without gnome, just a working X. In the original configuration the VM would use VESA and not support my desired resolution 1400x1050, so i decided to use the vbox driver with guest additions.
I managed to get X11 up and running with guest additions (installed dependencies and followed HOWTO:Install Linux Guest Additions + Xorg config), the resolution started as desired. My xorg.conf:

Code: Select all

Section "Server Layout"
   Identifier   "VBox Configured"
   Screen 0 "Screen[0] 0 0
   InputDevice "Keyboard[0]" "CoreKeyboard"
EndSection

Section "Files"
   ModulePath   "/usr/lib64/xorg/modules"
   FontPath  "catalogue:/etc/X11/fontpath.d"
   FontPath   "built-ins"
EndSection

Section "Module"
   Load   "dri2"
   Load   "extmod"
   Load   "glx"
   Load   "record"
   Load   "dri"
   Load   "dbe"
EndSection

Section "InputDevice"
....
EndSection

Section "Monitor"
   Identifier   "Monitor[0]"
   VendorName "Oracle Corporation"
   ModelName   "VirtualBox Virtual Output"
EndSection

Section "Screen"
    Identifier   "Screen[0]"
    Device   "Device[0]"
    Monitor   "Monitor[0]"
    SubSection   "Display"
               Depth    24
               Modes    "1400x1050"
    _EndSubSection
EndSection

The problem starts when i try to run any application, the xserver crashes with the following error in Xorg.0.log:
