plus. if I restart.. it shows error window:

Ubuntu is running in low-graphics mode
The following error was encountered. You may need to update your configuration to solve this.
(EE) Failed to load Module "I810" (module does not exist, 0)


After, the only option that work is "Run ubunu in low-graphics mode for just one session"
Others options just back to same question, it doesnt work

well, I press OK, it shows another message: "Stand by one minuto while the display restarts..." (also if i dont press OK it stays like this forever)

by clicking OK, my monitor shows error message:

Not Optimum Mode
Recomended Mode : 1280 x 1024 60Hz




I dont believe my video card or network card has problem, computer is new and by booting from Windows XP it works fine

Just curious:
Do you have another computer that you can use and attempt logging into the system using SSH while it is hung at "Starting NTP server ntpd"?

If yes then you can look at the startup shell script. I think they are located here:  /etc/inittab (ref: http://www.debianhelp.co.uk/boot.htm)
If you can locate the command that starts the NTP dameon you can try commenting it out to see if it still hangs when the system boots.

If it is NTP that is causing the hangup try moving the startup command toward the end of the startup process as it may not yet have network connectivity and is failing because it cannot contact the NTP server.

Sorry I had to run into town.
Let me get Ubuntu installed in a Virtual Machine so I can give you useful information.
What version are you running?

Okay.

Lets start by logging into the system with SSH. Once you are logged in do the following a the command line
su
Enter password for root when prompted

Change to directory /etc
cd /etc

List all files beginning with rc
ls rc*

You should get a printout of each file and folder beginning with rc. Beneath each rc# folder you'll find a list of files; some will start with K and others with S. You need to locate the file with S##ntp??????    It may be under rc2 directory. Once you've located it change to the directory it is located under:

cd /etc/rc#.d
ren S##ntp??????? K##ntp??????

the S is used to indicate that it should run. K tells the boot loader to ignore the script.

Reboot the system
reboot

Sorry REN is an old DOS command...I use too many OS's

Okay

cd /etc/rc2.d
mv S23ntp K23ntp

That should do it.

Reboot and let's see what happens.
