Then choose a screen saver so that it is not just blanking the screen out.. this happens when logged in as root most of the time depending on which GUI your running... which by the way which GUI did u choose or are you running Xw.

Then set the screen saver so that it kicks in after 99999 seconds... this will stop the machine from blanking out the screen...



Unless The problem is the reverse... This might be so as well

If you can't seem to un blank the screen enable power management in the bios and enable a hot key to wake the monitor up... and then enable the screen saver and set it to 9999 etc.

If no screen saver is chosen then when it blanks the screen sometimes if power management is disabled there is no way to wake up the monitor... depends on what irq's the system monitors or if the bios is told to watch any of them... i.e. such as wake on LAN etc... you can tell the bios what irq's to watch and when you enable irq for VGA make a note... go into the bios and make sure it is in the monitor list.

In this case you want to make sure in the bios you enable irq for VGA... so that you can add it to you bios's monitoring list.

Um, he said THE MONITOR TURNS OFF AND WON'T TURN ON. It's his X configuration. when you install Redhat there isn't even a screen saver set by default, but that doesn't matter anyway. The monitor is shutting down just like mine did one of the first times I installed Linux.

Fixing the X configuration solves this. Which is why I said he should get the manual for the monitor and see what settings are safe.

Which reminds me; If you can't find the manual for the monitor, or for some reason don't have it, look it up online and find the settings it can handle.
