Xorg does not start (timeouts) with "no screens found"

Question

After years of my system working correctly, this has been happening for the last ten days.
Many times - not all of them - xorg does not start, and I get greated with the standard console login prompt.
Checking in /var/log/ the xorg.0.log, it says that "no screens found".
I am using an nvidia VGA with nvidia driver 190.xx from extra.
I am using KDE, from inittab (not with kdm as a deamon).
Initial xorg.conf used to be:
Section "ServerFlags"
Option "AutoAddDevices" "False"
EndSection
Section "ServerLayout"
Identifier "Default Layout"
Screen "Default Screen"
InputDevice "Generic Keyboard"
InputDevice "Configured Mouse"
EndSection
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "CoreKeyboard"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
EndSection
Section "InputDevice"
Identifier "Configured Mouse"
Driver "mouse"
Option "CorePointer"
Option "Device" "/dev/input/mice"
Option "Protocol" "ExplorerPS/2"
Option "ZAxisMapping" "4 5"
Option "Emulate3Buttons" "true"
EndSection
Section "Monitor"
Identifier "My Monitor"
Option "DPMS" "True"
Option "DPI" "96 x 96"
EndSection
Section "Device"
Identifier "My Graphics Card"
Driver "nvidia"
VendorName "NVIDIA Corporation"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "My Graphics Card"
Monitor "My Monitor"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes "1280x1024"
Viewport 0 0
EndSubSection
Option "DPI" "96 x 96"
Option "AddARGBGLXVisuals" "true"
Option "TripleBuffer" "true"
EndSection
Section "Extensions"
Option "Composite" "enable"
EndSection
Now I have trimmed it down to:
Section "Device"
Identifier "My Graphics Card"
Driver "nvidia"
EndSection
But the problem remains.
The problem started ten days ago.
The previous night I had updated the following packages (I provide a section of pacman.log):
[2010-01-21 20:35] upgraded acct (6.3.2-2 -> 6.5.1-1)
[2010-01-21 20:35] upgraded coreutils (8.2-1 -> 8.4-1)
[2010-01-21 20:35] upgraded farsight2 (0.0.16-1 -> 0.0.17-1)
[2010-01-21 20:35] upgraded git (1.6.6-1 -> 1.6.6.1-1)
[2010-01-21 20:35] upgraded iproute2 (2.6.29-3 -> 2.6.31-1)
[2010-01-21 20:35] upgraded mkvtoolnix (3.0.0-1 -> 3.1.0-1)

[2010-01-21 20:35] upgraded zlib (1.2.3.4-3 -> 1.2.3.4-4)
[2010-01-21 20:35] upgraded recordmydesktop (0.3.8.1-1 -> 0.3.8.1-2)
[2010-01-21 20:35] upgraded smbclient (3.4.4-1 -> 3.4.5-1.1)
[2010-01-21 20:35] upgraded samba (3.4.4-1 -> 3.4.5-1.1)
[2010-01-21 20:35] upgraded smartmontools (5.38-2 -> 5.39-1)
[2010-01-21 20:35] upgraded tzdata (2009t-1 -> 2010a-1)
[2010-01-21 20:35] upgraded whois (4.7.36-1 -> 5.0.0-1)
So since nothing on xorg was updated, maybe the new coreutils is the more likely suspect?

no, i install nvidia and then xorg i try startx without result.
Right now i am from Ubuntu, i am going to install arch on virtualbox and i will answer to any other questions.
Thank you
The reason you were asked if you rebooted is because installing the nvidia driver also installs a kernel module. That kernel module
needs to be installed in the running kernel, either by invoking "depmod nvidia" or rebooting, providing everything installed correctly. You
may need to put the module name in your modules section of rc.conf and then reboot.
The absence of that kernel module explains your error message of not finding that kernel module. :-)
iirc the .install already does the depmod
Note to TS:  if you use virtualbox you can't use your hosts video card so you will have to use the vboxvideo driver. So read the wiki about virtualbox
