How to execute kernel for more than 5 - 6 seconds ?
I’ve seen posts regarding this, and seems that watchdog timer is related to this.
I would like to execute the kernel for a long time…
Is there any solution ? such as disabling watchdog timer… ?
Thanks

Are you using Linux or Windows? On Linux, there is no watchdog if you do not start the X server. You will need to use the script mentioned in the driver release notes to create the /dev/nvidia* device files, though.

If you use Windows, I’m not sure. Generally, the answer is install a second video card, but there may be some registry hack. Hopefully someone else can comment here.

Thanks.

I’m using Linux.

Can I simply edit the /etc/inittab and change the value to 3 to prevent from X server starting ?

Or there is a better way ?

The “best practice” could differ greatly between different dists. Which are you using?

@shong9: In Ubuntu, i can log out of X server and go to a command line TTY and shutdown the X server even after u have booted up the X server. with the command /etc/init.d/gdm stop.

in ubuntu you don’t need to kill the gdm actually… all you need to do is to switch to a tty and execute :-)
