General :: Turn Off Monitor (Energy Saving) While In Text Console Mode
Nov 3, 2010
How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup.
The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen). But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor?
I installed fedora 13 in its LXDE flavor in my laptop. I noticed when it goes to save energy mode, the TFT retro-illumination is not turned off. The display just stays black with light. How to make the display to turn off when the system enters in save energy mode?
I've recently changed to Debian from Windows, it's a really great adventure so far, but I have one problem. So as I see you can set your monitor into "Blank Page" after 10 or any minutes to save power, like in Windows. 10 minutes passes, without any movement my monitor's led turns into orange and the monitor turns off, that's great, that's what i want.
But after a few seconds the led turns green (like when it's on), and it brings up a little box : "Power Saving Mode" (just like it did after 10 minutes), and it turns off, and then stars again from the beginning . And this goes on repeatedly until a move my mouse to get back from "Blank page" state. (It's like the monitor tries going into power saving mode, but it gets always a little bit of power, to show that text box, and start all over.) So what can I do? I use debian 8.0 "jessie", and my monitor is a LG L1750S(with Nvidia GeForce 9600 GT).
All of a sudden today there was no display on my Ubuntu PC. It seems to be powering on - I get the LG screen when the monitor is switched on - but it goes into "Power Saving Mode". How do I diagnose this? I already unplugged and plugged. Monitor is connected to a graphics card - no change when I switched to VGA.
when my monitor turns off after 30 minutes, I cannot do anything after. We're talking complete lock down of Ubuntu 10.04 64-bit. Not even alt+printscreen+REISUB reboots the machine; I have to do a hard reboot (which sucks and is hard on hardware).
When I try to load Ubuntu (recovery mode) or if I press Ctrl+Alt+F1, the image gets corrupted showing a white screen with black writing on it, but which is unreadable. Also the words seem to be spelled backwards. I'm trying to install an NVIDIA driver and I need to stop first the X server.
I run a custom build of linux running kernel 2.6.24 and busybox. At the moment I'm investigating a kernel panic. The problem is that after 10 minutes the screen is blanked, i.e. it is still on but has been turned black. If you press a key then the command prompt is shown once again, but if the kernel has crashed then this won't work and any info about the panic is inaccessible. So I'd like to prevent the display being blanked. I've tried booting with 'apm=off' and 'apm=off acpi=on' kernel parameters but neither had any effect.
I run a number of Ubuntu 9.10 boxes attached to multiple daisy-chained KVMs. None of the PCs are using any GUIs - they all run in console mode. I often reboot them remotely via an SSH session, etc. If a monitor isn't actually active on the PC when it reboots, Grub2 uses a low-res video mode, despite having a higher-res video mode set correctly in Grub2's configuration. If I reboot WHILE THE MONITOR is attached to the Ubuntu PC via the KVM, the video mode is set correctly as configured in Grub2's config files. If I reboot WITH NO MONITOR attached, the video mode is ignored and I'm stuck in a low-res mode next time I attach to the PC via the KVM. How can I force Grub2 to honor the configured graphics setting, despite not having a monitor present at the time it boots?
I've installed an Ubuntu GNU/Linux 10.04 Server (Lucid Lynx) in a great computer, but with a small and old CRT monitor, that doesn't support much screen resolutions and frequencies. How can I do to make the system to use everytime traditional text mode (80x25 characters or compatibles)?
After installing Ubuntu 10.10 on a laptop Acer Aspire 5942G graphics card ATI Mobility Radeon HD 5650, some time after the boot falls color monitor. Color depth is only 65000 colors or more. In all settings, all is well (and the color depth is there spelled 24bit). Color depth is reduced at some time after a reboot. After further experiments with the screensaver was set: color spoils the energy saving mode and turn off the display!After disabling the option "disable display through .." color is now always saved in the norm!
I installed Fedora 11 on my system (see below) using the i686 DVD. The graphical install worked just fine, and after the system booted back up, the X server was working very well.
There is no boot text. On the other system with Fedora 11, I can see the boot text scroll by in the window and/or a progress bar at the bottom of the monitor during the boot sequence. On this system, the monitor says "No Input", and nothing appears until the login prompt for the X window. I am able to enter the BIOS configuration page and navigate through it without any issues. I can also edit the grub commands before Fedora loads without a problem.
If I boot in text mode, no login prompt appears. If I wait long enough, the monitor enters the power save mode since it is not receiving a signal. I am able to log in to the system with my user name and password, and then start the X server. Once the server starts, the monitor turns back ON and all is well.
From the X window, I use the CTL+ALT+F2 key to enter text mode. The monitor stops responding. If I press the ENTER key a couple of times, then press ALT+F7, I can briefly see the text window with a couple of login prompts before the X window starts responding again.
How can I get the text mode to work? Why is there no input to the monitor when booting?

I am having problems with the refresh rate if the screen. In the refresh mode of the monitor in the monitor options have only one option 60Hz. I have LG 24 + ATI Radon 3870, and have already installed the ATI driver via Ubuntu download center.
I usually work with plain text files, and when moving them across platforms, the differing format creates problems. I want that whenever I save a file with extension *.txt, it be saved as DOS format, and all other extensions or without get saved as Unix format.
I am using CentOS 5.5 (64 bit) and want to know the command to turn off day light saving settings permanently. I only have SSH access to the server so please let me know command so that I can turn off that settings.
I have just come over from the darkside (Microsoft) and am finding problems with a few items.
I am trying to configure the monitor/video card as I am having problems with the nvidia geforce 4 integrated video card. Some instructions I have sat to press ctrl alt and f1 to go to the text console. I do but it asks for a login and does not accept my user name and password.
I have been dual booting my XP and Ubuntu for a while now. However, my pc monitor does not turn on until I am booted into windows/linux. This means I have to 'guess' to a certain extent which OS to select on boot (using GRUB). I expect I will have to change a setting in the BIOS but I am not too sure what to look out for.
After turning on my pc I have to restart it for it too do anything, it appears to just hang!However as I cannot see what is happening due to the monitor problem I am completely in the dark as to why it would do this/what is going on! I have XP installed at the front of my hard drive and Ubuntu at the back. It worked ok the first time I tried it after install (still had the monitor problem but was able to guess) then after that this random problem!
GNU/Linux kernel 2.6, Slackware 12.0 KDE 3.5.7, Kmail 1.9.7
To any user of an email program running on KDE: Let's call Kmail to such a program. When I am in the GUI, Kmail notifies me of any email that is entering. It does so by playing a .wav file through the loudspeakers (and displaying a little window in the desktop). But what happens if I am in a text console? Let's says I pressed Ctrl+Alt+F3. So now I am in virtual console #3. Shall I hear the sound? This question mortifies me.
I am using a virtual pc software called VMWare workstation ver 7.1. platform win 7. I installed a redhat linux 5 in vmware. I am able to access graphical mode but unable to access the console mode (ctrl+alt+f1....f6).
Is there any way to specify which monitor the console is displayed on in Linux?
Details: I have a 3 monitor setup with 2 video cards. When I boot the computer, the BIOS displays on the PCI graphics card (which has a small monitor). When starting Linux, the console is displayed on the same monitor. Is there a way to have the console output on a different monitor? I'm using the vesafb framebuffer.
I don't see a way in my BIOS to change the default video card.
During startup (suse linux old distro) LILO immediately after stratup procedure I can see login for about 1 sec and then Xserver starts. I'm unable to kill it with Ctrl+Alt+Backspace or Ctrl+F1..So the question is: is there any way I can force linux to boot into console mode before it starts xserver? (I'm unable to modify any files since I cannot reach the consol mode)?Is there any shortcut ky I need to press during boot in order to prevent GUI from starting?
I have posted about 20 Slitaz Video Tutorial I made. I thought it might be helpful for new comers to Slitaz. I've have 2 playlists. One for the GUI interface and one for Text-Mode. Both playlists can be found at:[URL].. Let me know if there is anything you would like me to go over in future tutorials.
I've been using Linux for about a week, now, and yesterday I finally got my audio to work. Before shutting-down yesterday, I installed some more audio-plugins. When I started-up my computer today, there were errors in the console-text that appears while the Debian Linux OS is loading. When I got to the desktop, I tried to play music, but no sound came-out. So, I tried to uninstall the plugins I installed yesterday and restarted. I got similar errors in the console-text as earlier. When my desktop loaded, I still had no sound. I had several problems with the entire sound architecture of the computer. I made some more changes in the application-download-manager-thingy and restarted and I no longer got the errors at boot-time.
Unfortunately, I still have absolutely no sound, and it appears as if ALSA is effectively dead. My soundcards are Rocketfish (PCI) and Realtek HD Audio (Integrated). I got Realtek to work yesterday with OSS.
Another problem is that WINE doesn't work, with the exception of WINE's default programs. I've been trying to get this thing to work for at least four days now, and I've made absolutely no progress...
Also, after fighting with it for a few days, I finally managed to get the internet to work, but Linux still thinks that I'm offline. It's really weird. This one's not so much of a problem as it is annoying. In addition, if I click-on the network-manager-thingy, it says that none of my connections have ever been used. Odd.
Basically, About 50% of the time, the system boots and sets the console resolution to something strange, and the console renders in a small box in the top-left hand corner of my screen. This causes problems not only with the display of the console, but with the display of X as well.
I have an Intel GL40 chipset on this laptop, with an integrated GMA4500 GPU. I am using the latest stable Intel video drivers (2.10.0-1), and have tried using the git drivers. In addition, the problem has been occuring since December, when I install Arch linux on this machine, I have just now had the time to address it. So basically, the issue has persisted with all driver versions since mid-December to the latest releases.
In addition, I have tried using several kernels, including:
But the problem persists with each.
I wish I could give you relevant diagnostic information for this issue, but if I had any idea where to start...
I will gladly post any information necessary. I was going to post a copy of everything.log for a successful and unsuccesful boot, but unfortunately they put me over the posing limit by about 100,000 characters each.
I guess, on second thought, that my Intel video driver really wouldn't have anything to do with my console, now would they?
