After installing Ubuntu 9.04 Jaunty and enabling the nVidia 180 driver (onboard video is a nVidia GeForce 6150 LE), I restarted the system and was greeted by the normal login screen. However, after logging in, my screen (Dell 2407WFPHC) went blank with a monitor message that the resolution was out of range. It appears that many people are running into this problem. The following fixed it for me.

1. Open a terminal window
2. Go to the X11 directory (cd /etc/X11)
3. Make a backup of the current xorg.conf file (e.g., sudo cp xorg.conf xorg.conf.backup)
4. Use your favorite editor to open xorg.conf (e.g., sudo vim xorg.conf)
5. In the section “Device”, add the following line:
   Option “UseEdid” “False”
6. The “Device” section should now look like the following:
   Section “Device”
   Identifier “Default Device”
   Driver “nvidia”
   Option “UseEdid” “False”
   EndSection
7. Save the xorg.conf file
8. Log off and restart the X server (from the login screen, click on Menu and select Restart X server)

That’s it. Now, when I log in, I’m able to see the screen and select a resolution using the nVidia X Server Settings tool.

Note: In the nVidia X Server Settings tool, if when you click the Save to X Configuration File button, you get an error message that it can’t save, run nvidia-settings from a terminal window using gksudo (for Gnome, e.g., gksudo nvidia-settings) or kdesudo (for KDE, e.g., kdesudo nvidia-settings). If, instead, you get a “can’t parse xorg.conf”, just rename /etc/X11/xorg.conf to something else so nvidia-settings can create a new file.

Can’t set your screen to the native resolution of your monitor? See the companion post, Ubuntu 9.04 nVidia Driver Screen Resolution Problem.
