Redhat 4.8 Hibernate/Sleep/Standby question


Hello all,

Here is my issue- I'm using a redhat 4.8 kernel command line only and it seem that after 15-20 minutes the monitor will shut off(I assume go into sleep mode) and I can't wake it up with the mouse or keyboard, I have to manually restart the machine.

Is there a way to turn off this via command line? or any ideas as to why this is happening?

thanks!

Hello,

I would have a look at /var/log/pm-suspend.log and see if you are getting any errors, this will aid in troubleshooting. I would also have a look at your dmesg output, along with /var/log/messages.

Cheers,

Josh

Have a look at xset.
Code:
man xset
From the man page:
Code:
    For screen-saver control:
	 s [timeout [cycle]]  s default    s on
	 s blank              s noblank    s off
	 s expose             s noexpose
	 s activate           s reset
So in this case, you will want to run the following:
Code:
xset s off
Just note that you need to run that as root.

Cheers,

Josh

Really appreciate the quick reply-

My linux skills are very dated- just to confirm.

1) I log in as roo
2) in the main shell, I type "xset s off"

This will shut off the sleepmode/screensaver?

If you read the man page, you will see that by doing that, yes it will disable it.

Cheers!

You just need to install it then. Install the xorg-x11-server-utils package in order to get the needed dependencies for xset. Quick question.... Did you pay for redhat? If so, you can use yum to install it:
Code:
yum install xorg-x11-server-utils
If you didn't pay for support, you will need to manually download the package. I also recommend that you upgrade your system to the newest version of red hat.

I found this link

http://rpmfind.net/linux/rpm2html/se...1-server-utils

should I get the rawhide one? or x86.. or i386?

then i use this command to install the package?

rpm -i nameofrpm.rpm

but do I have to specify the location of the rpm? it will be on a external hard drive.

then I run the xset command ?

Well what is the architecture of your computer? Run the following and post the output for me:
Code:
uname -a
Alternatively, you can also download the source of the package and compile manually, but for now, let's just stick to the RPM's.

I just noticed that if I use a ps/2 mouse and keyboard into the machine, that will wake it up from sleep-

But a usb will not.

the command gave me this

linux sefcs 2.6.9-89 ELSMP #1 SMP "the date" i686 i686 i386 GNU/LINUX
