I've got my Redhat Linux 8.0 running in either runlevel 3 or 5. I leave the server alone for about 5 - 10 minutes, I come back, turn on the monitor, and wouldn't you know it - the screen has been "blanked" (no screen saver). During the time that the screen is "blanked," I can't access any network services (web server, webmin, etc.). Once I return to the "physical" terminal and move the mouse, the screen "unblanks" and seems to restore everything, and I can then remotely access services for another 5 - 10 minutes.

I am super frustrated people. Any ideas?? Please? I will thank you forever!

Probably you have a hardware bug in your motherboard. See if it's related to the console blanking with this procedure:

1. Log in at a virtual terminal (text mode one, _not_ X, telnet or any other pty)
2. Run "cat"
3. Type in these keys (ie. keyboard keys, not characters), _exactly_:

<ESC> [ 9 ; 0 ] <RETURN>

4. Type CTRL+D to exit cat and log out.

That issues the escape (hence the escape key) sequence to disable console blanking, so see if it still stops after that.

Thank you very much, but it didn't seem to help...
I typed everything after entering cat, (one line, right?)
and I think I did it right...

You wasn't suppose to type it exactly as it said, but interpret it as the keys to press, ie. first you press the escape key, then the [ key, and so on. I thought you misinterpreted it, since you asked if it should be one line, even though I included the enter key.

ok, so after I log in and run cat, then commands, it will look EXACTLY like this?:

[root@localhost root]# cat
^[[9;0]

[root@localhost root]# logout

login:

Yeah, that's basically it. Did it help?

No blank screen anymore, but internet/web still cut off. When I turned on the monitor at the login screen and pressed a key, the following message came up:

TLAN: eth0: Starting Autonegotiation
TLAN: eth0: Autonegotiation complete
TLAN: eth0: Link Active
eepro100.c

Maybe this is the problem?

It would almost seem like your NIC enters some powersave mode or something (which seems really stupid, but it still seems like it). Run "modinfo -p eepro100" and post what it returns.
