Monitor goes off for less than one second


Hi friends,

I am a newbie in this ,My distribustion is Debian, After Installation I succesfully changed my resolution to 1024x 768 from 800x600 by editing XFConfig file.

But after that sometimes screen goes full blank for a fraction of second
and this is repeating in every 20/30 minutes.

Some times i observed this same problem while correcting System date

My current XFxongig file is given below. Pls help me in this

I don't know much about it either... NTP is the Network Time Protocol, and ntpdate is one of many clients which connect to a time server to set your clock correctly.

It's just an idea, but you say this happens when you set the system clock (it does, indeed, I have noticed that, too), then maybe it is because some background process manipulates the clock?

Check if there are any ntp clients running
ps | grep ntp
ps | grep chrony

It wouldn't show up as a running process unless it was trying to run as you checked. A better way to stop that from happening would be to do this as root:

Code:
/etc/init.d/ntpdate stop
And then let it sit for a bit. If the 20 minute "flashes" stop, it was ntpdate. If they continue, we'll look elsewhere.

Peace,
JimBass

May not be because of ndpdate

thanks GimBoss, I checked that but no such file in that directory


PHP Code:
node5:/etc/init.d# ntpdate stop
bashntpdatecommand not found
node5
:/etc/init.d

No man, you can't execute a command from within its directory like that. The correct way to do that would have been like this:

Code:
node5:/etc/init.d# ./ntpdate stop
Or if you are in any directory, you can issue the full path and it will work.

Code:
node5:/home/you/#/etc/init.d/ntpdate stop
Peace,
Jim

let's try this then -
Code:
ls -al /etc/init.d/n*
Would be funny if after all this ntp discussion you don't have it installed!

Peace,
JimBass

I think you are right

Hi Jim, this is the result

[HTML]node5@node5:~$ ls -al /etc/init.d/n*
-rwxr-xr-x 1 root root 2651 2005-03-22 00:19 /etc/init.d/networking
-rwxr-xr-x 1 root root 1984 2005-01-05 18:08 /etc/init.d/nfs-common
-rwxr-xr-x 1 root root 2305 2005-03-07 04:59 /etc/init.d/nviboot
node5@node5:~$

Well, we can scratch that out then. You don't have ntpdate, so all of our ideas have to be rethought.

Peace,

Sorry man, I don't know what could be the cause of it. One thing that is worth checking out would be the horizontal and verticle refresh rates for your monitor. it is possible if you're just a little bit off that the monitor might "freak" out for a bit. Slim chance, but it is worth a look. If you have the booklet that came with the monitor, you can find the correct refresh rates there, or you can go to the manufacturers website, and get the docs for your specific model and find the rates in there. Then put those values into the Xfree86 conf file, replacing these values:

Section "Monitor"
Identifier "500G"
HorizSync 30-54
VertRefresh 50-120
Option "DPMS"
EndSection

Peace,
JimBass
