How do you stop gentoo from blanking the screen.

I run gentoo without X - just cli and every x minutes the screen goes black. I don't think this apm as I didn't even compile apm support into the kernel. Must be a tty type setting. Anyone know what needs to be changed.

Thanks.

If I leave my computer for a few minutes, the screen always blanks out (as in screensaving not as in a weird graphical error). I don't want it to blank. I only want kde screensaver to run.

I tried

xset s 0

and

xset s nobank

but that didn't help.

Any ideas?

Thanks.

Can anybody tell please how to switch off that annoying console screensaver? Or change the time it gets on?
Couldn't find the info in /etc, sorry.
Thank you.

BTW, can I change it to some other one with a moving picture or something?

setterm -blank <n>
might help.

This isn't really a problem, just something I'd like to change the time on. Whenever there is no activity for a couple minutes (around 5 maybe), the monitor will go black. I didn't want ACPI on this machine, so I compiled the kernel with out it. Is there a setting somewhere that I can adjust this interval. I am not running X or and desktop yet. (it's still compiling) So, it's doing this just at the bash prompt and while compiling. Hitting a key (i've been using caps or num lock) will bring it back up. TIA.

Use setterm, somethink like setterm -blank 0 or setterm -powersave off, see man setterm.

All right, so I just installed Gentoo and I'm ready to start emerging some apps. However, I'm having a problem, though it's possibly not a Gentoo or even a Linux issue. I emerge gnome (or anything big, it wouldn't matter). It's going fine. I leave it alone for a while. I stop paying attention, and eventually my monitor goes dark because that's what my monitor does. When I come back, I can't get the monitor to show anything again! I hit the space bar and nothing happens, and I see the caps lock light blinking on my wireless keyboard's base station, which makes me wonder if something's wrong with the keyboard (though this last time, the light stopped blinking when I hit space, so I don't know). I haven't had any trouble with the keyboard other than this.

This is the third time I've tried emerging gnome, and I decided to open a different virtual console and run top there, just to see if that would somehow keep the monitor from going dark. It didn't. Now I don't know what to do, because I have no way of knowing how far along it is in emerging. The first two times, I rebooted my computer because I didn't know what else to do. The second time I tried it, I noticed there were about thirty fewer dependencies, which I suppose were installed the first time before I rebooted. The third time, it was the same number as the second time. I don't want to reboot again, because I don't want to cut it off in the middle of its emerge. But it sure would be nice to know what's going on.

So I guess my question is, how do I get my computer to stay awake while I'm emerging something big?

Thanks in advance.

well, my monitor does that, but it always comes back when I use the KB.
what about alt-f2 to switch to a different text console, and alt-f1 back.

Other wise, you could try running your emerge under nohup and background it. ie

When I first started using Gentoo my computer (a laptop) would power off during a long emerge. It took me a while to figure out what was going on, but eventually I found out that I had APM support in my kernel was configured improperly, which meant the fan wasn't turning on when it was supposed to. An emerge is very processor intensive, so during a long emerge my CPU would overheat without any cooling and trigger an automatic shutdown.

Maybe your computer does this standby thing when it gets too hot instead of turning off. You could try listening for your CPU fan while emerging; if that turns out to be the problem you'll need to reconfigure your power management (I did it by switching to ACPI) or just turn power management off in your grub/lilo conf.

Another possibility: If this turns out to be a sleep when idle feature (did you compile ACPI sleep states support into your kernel?) then disabling power management in grub.conf should still stop it.

Thanks so much for the ideas. It's unresponsive now; I'm going to leave it alone for now in case it's still doing the emerge, and turn it off and back on tomorrow and try these things. I think that it probably is a kernel issue, because I didn't have a problem like this with emerge system and so forth, before I compiled my kernel. Nor did I have a problem compiling the kernel itself. It's only after I rebooted and started using my new kernel that this started happening. So yeah.

I honestly don't know if I compiled in ACPI sleep states support. :/ I used genkernel with --menuconfig and pulled out everything that I thought I wouldn't need, so it's possible that I didn't compile that in. But I was mostly pulling out things like RAID and SCSI support that I was absolutely sure I wouldn't need. I'll check tomorrow.

Here's an update. I did two things to try and fix the problem. First I added acpi=off and apm=off to my append= line in lilo.conf and rebooted. It looks like

I swear to God, I'm not trying to up my post count...just documenting my steps. =)

I realized that before, I forgot to log in as root before doing the emerge. So this time I did exactly as I did above, except as root, and this time with my case open and keeping an eye on the processor fan (which is four years old and missing a blade -- I should probably get a new one anyway).

I even attached and detached from the screen session a couple times to make sure it the emerge was going like it was supposed to. It was. So now I'm logged out, still emerging, and just waiting for my monitor to go off...or not...

All right. My monitor went off twice, and twice I came over and hit the keys and my login prompt came back. The third time it went off, I came over and hit the keys, and what came up on the screen was some garbage that looks like part of what a configure script usually writes to the screen. It's only covering part of the screen, though, and it's not actually doing anything, just sitting there frozen across the screen. This is very strange, because I was logged out! And once again, the caps lock light is blinking on my Logitech wireless keyboard's base station. (I have no documentation on what it means when that light blinks, but I think it's related to the computer's standby problem because it's the second or third time I've noticed them happening together.)

I am now completely lost. Any help would be greatly appreciated.

For what it's worth: When I was installing from the LiveCD, whenever I left my computer running doing something (like bootstrapping) for a long time, part of the screen would freeze showing some stuff similar to what I'm seeing now -- looked like stuff from the screen output of configure or make. But whenever I woke up the computer by doing anything with the mouse or keyboard, the screen would go back to showing what was actually going on. At the time, I figured the funky stuff on the screen was just a quirk of the LiveCD. Now I'm not so sure.

Oh yeah, and I've been watching and listening to the processor fan. It's fine.
