You can add the following sections/options to your xorg.conf

Section "ServerFlags"
     Option         "DPMS" "true"  # To control screenblanking
     Option         "DontZap" "false" # Allows ctrl-alt-backspace to
                                      # restart X.

Section "Device"
     Identifier     "Device0"
     Driver         "nvidia"
     VendorName     "NVIDIA Corporation"
     Option         "TripleBuffer" "true"  # Allocates more 2D buffers
     Option         "DRI" "true"

Section "Monitor"
     Identifier     "Monitor0"
     VendorName     "Unknown"
     ModelName      "Unknown"
     HorizSync       28.0 - 33.0
     VertRefresh     43.0 - 72.0
     Option         "DPMS" "true"     # To control screenblanking

Then use ctrl-alt-backspace to restart X (no hard boot required).


         Please let me know if anything I say offends you.
          I may wish to offend you again in the future.
