Hello, I have a server at home with no X at all (no need). but it's an old laptop, so with screen attached and the screen keep on all the time. In my memories I remember having a screen saver even in the time where my computer was too short for X to works, but don't find it. any way to blank the screen or protect it from burning? thanks jdd -- http://dodin.org

I thought that was a problem with CRTs, not LEDs or LCDs.
i do not think so, my (new) curved hilips screens "328E" say in the manual that you should not let the screen for a long time with same content. (because of some sort of damaging) so i am wondering why there are in standard installations there are no screensavers installed and for some older lcd screen connected to a mechanical machine, running about 12 years, i could confirm that the lcd display has a burned picture. simoN -- www.becherer.de

Turn the monitor off when not using. I have two computers at home that run 24/7. I turn the monitors off. I have two computers on my desk at the TV station that run 24/7. We are at times gone from there for weeks. I turn off the monitors. -- Women and cats will do just as they please. Men and dogs should just get used to the idea.

lcd displays will not have this problem is not true and for my new phillips i was talking, its inside the manual that its not true. - of course kde switch off monitor after some minutes. there is still the question for the desktop: i have a good organized desktop with about 20 symbols at the top corner, screen is big enough to let them always visible and work on other areas. so my fear is, the will burn in when working continuously whole day. same problem with standard suse/kde background picture which is in upper right corner always visible. - so for my opinion, best solution would be to move background picture and symbols over time a bit around. simoN -- www.becherer.de

Another possibility would be to darken the display after a while of no use of the computer. This is what "kodi" does. -- Cheers / Saludos, Carlos E. R. (from 15.2 x86_64 at Telcontar)

No - in my case, that monitor is sat in 19" rack, with a keyboard on a pull-out drawer. On those occasions when you need it, you will be back and forth to the machine(s) it is connected to, and you will likely forget to return to switch it off when you're done. or you're interrupted etc etc. Much the same in an office, people don't switch monitors on and off all the time, just because they're having a coffee or a meeting or whatever.

Only one stays on all the time. All the rest are on during the day but when closing for the night we turn them off. Production also has several monitors. All the monitors are turned off at night. Not so difficult.

Why would you turn them off when going to the canteen for a coffee. Aren't you coming back in a reasonable amount of time. I don't turn my monitor off unless it is going to be unattended for an extended period of time. Like going to bed at night. Or, in the case of the TV station, we are going away for a week/month/ whatever. Burn in won't happen in an hour or two. It takes an extended period of time. -- Women and cats will do just as they please. Men and dogs should just get used to the idea.

Many years ago, KDE had a digital clock "screen saver", which provided a digital clock the size of the monitor screen. Unfortunately, it was dropped several years ago. An aside, many years ago, when I was at IBM, they insisted that screen savers be used to automatically hide the contents of a screen and security people would come around occasionally to verify that was happening. So, I took a screen shot of my desktop and used it as my screen saver image. ;-) I didn't hear about it, so I assume they tried to do something and found they couldn't without the password.

Huh, unless it is a bad translation, or a bad interpretation by me, jdd said that the virtual terminals are gone, and I just said that I do have the virtual terminals in all my computers. Not that the have screensavers moving images around in the virtual terminals in text mode. (I understand "screensaver" as the program of that name, or similar equivalent software) However, in my laptop at least the virtual terminal number one does power off after a while, and I don't know/remember how.

One thing is that the laptop has "/etc/laptop-mode" (Laptop Mode Tools).

And yes, what my laptop does match what the file describes.
this may be the best answer. On my machine, laptop-mode was *not* installed, but I could install it.
not sure if it works right after install or if I may have to reboot (not to be done very soon)

Care to retest now? I guess it should work now on most of the actual drivers. But I found that it's still broken on KVM/QEMU bochs, qxl and cirrus drivers while virtio works. I need to rework for a patch to address those on the latest kernel. The bug was completely forgotten. Takashi

I could add consoleblank=600 to the kernel command line (with yast), reboot, and it works as expected thanks jdd -- http://dodin.org

Execute: setterm -blank 5 -powerdown 6 or ... create a systemd service to do it for you. Just add: cat console-blanking.service ## systemd service file to restore default blanking and powerdown fo # virtual consoles after a given timeout period (5-min blank, 6-min powerdown) # this functionality was originally provided by the kernel defaults setting # /sys/module/kernel/parameters/consoleblank 600 (now 0-disabled). the # blanking and powerdown were delegated to systemd to implement, but no ## service was ever provided by systemd to accomplish this fundamental task.

Yeah, David Haller also told us about that, but it doesn't work, or at least not always. see https://bugzilla.opensuse.org/show_bug.cgi?id=1095700 Mind you, that was about three years ago, I guess it is time to go and try it again.

There shouldn't be any differences, but it has, and continues to work perfectly on Arch. https://aur.archlinux.org/packages/console-blanking/ This was frustrating when the kernel just yanked default blanking. Think about the number of monitors world-wide for severs that just stopped going to sleep. Global temperature rise projections went up by 2 degrees C.... It really was one of those why did they do it? What benefit does removing it offer, and why are we still having to deal with it now. It may have seemed like a neat idea (give it to systemd), but then never implement it in systemd. Best solution I've found is the use of setterm -blank 5 -powerdown 6 and incorporating that into a service. Onnce enables the monitors actually turn off again (backlight, everything) instead of just sitting there with a dull-glow, I'll look at them bug and see if we can do soething similar for opens -- David C.
