General :: Xorg DPMS Off: Keep VT From Turning Screen Back On
Mar 19, 2010
I have an embedded board with a small UPS. When AC power goes down, I need to turn off all power hungry devices in order to have a clean shutdown. First thing I do, is set DPMS to force powerdown, then go through the usual SIGTERM/SIGKILL/umount sequence. I have an Intel i915 Display adapter connected to an LVDS LCD panel.
Unfortunately, when Xorg dies, Xserver or the VT code turn the LCD panel back on.
I even tried working around it by directly poking the panel enable register in the Display chip, so that X doesn't know about it, but the panel goes back on when the VT comes back.
Is there any "legal" way of keeping the display off?

I have a netbook (Acer Aspire One) I'm running Slackware 13. and usually, I prefer to connect an external monitor. When I switch my machine on with the monitor connected, the display is duplicated on both screens and since I just want the netbook's screen to be off and only see the display on the external monitor, I can doxrandr --output LVDS --off
Great! However, it's a hassle to do this every time I log in and I'd like to automate the process if possible. I did some googling and I found that if you want to automate xrandr commands, you can put a script in /etc/X11/Xsession.d/ (see this). I wrote the following script to automate my xrandr commands and since the Xsession.d directory didn't exist, I tried creating it. The script was called 45custom-xrandr_settings, as the one on the RandR wiki is called the same.
Code:
#!/bin/bash
# Check whether the external monitor is connected

After upgrading to Mythbuntu 10.10 from 9.10 (clean install) on my combined front/backend I cannot get monitor (Dell 3007) to switch off from remote, I have been using simple script to DPMS force off for years with no problems, it still works, but some random time later the backlight comes back on. I have tryed the more complex scripts that stop and start the frontend and all of the acpi_osi options. Disabling screensaver has no effect. what causes this, or how to fix? Sysem is Abit IP35e (I suspect this board is the problem)
[Code]...
I have 2 remote frontends both upgraded OK. I have tryed installing 10.10 on a 'scrap' P4 machine, DPMS off works fine on it. I would try another install and/or another MoBo but its the only TV system in the house now.

the screen is still on but it's like the computer is going idle or something, It makes watching tv shows/movies pretty hard. I have to constantly keep moving the mouse. I have a pentium 4 with about 600 megs of ram. Latest version of Xubuntu.I went into screensaver options and power management options. It's set to two hours before the screensaver comes on, and never to put the screen idle but the screen seems to do it every 20-30 minutes.I'm not entirely sure where to look now, i don't think there could be anything wrong with the hardware, otherwise moving the mouse wouldn't make the screen come back on.

I have an Asus Eee PC with Ubuntu Netbook Remix (Unity). The other day, I turned off the wireless using the keyboard shortcut to save battery life when I was somewhere without wireless, but now it's not turning back on. I tried restarting, I've done the keyboard shortcut several times, and it still just says "disconnected" for wireless and wired, even though there are several wireless networks around me right now. There aren't any options in Network Connections or Network Tools to turn on the wireless. Is there a way to manually turn it back on?

I have actually done a bit of searching on this, but the suggested solutions either don't work or are not applicable to my setup.First, I changed the setterm link in /etc/rc.d/rc.M to be setterm -blank 0 -powersave off -powerdown 0and have xset s off in my fluxbox startup file.Nevertheless, the screen goes blank after 10 minutes. I can't figure out what is causing it and how to stop it.

I have an issue where the screen on my laptop will not shut off with the power management tool. The Default Power Manager does not have an option for this.My screen will go blank after a set amount of time, but the lcd-backlight will remain on. I would want the power manager to shut the screen off completely (including turning off the lcd backlight) without shutting down the computer it-self. So the computer can continue to do what I left it to do in the case I forget to close the lid. With the screen shut off completely, will preserve the life of the back light and reduce power consumption.
Is there a better power manager app that will allow me to do this a tweak to the existing default power manager that will allow the functionality I am seeking? laptop was perfectly able to do this under a win-xp environment, so I know the machine is physically capable of doing this. Note: My WinXP OS and Ubuntu OS are on seperate physical drives so there is no dual boot issues. So when I am using one there is no trace of the other present

I am using Linux 2.6.29-020629-generic #020629 SMP Tue Mar 24 12:03:21 UTC 2009 i686 GNU/Linux ubuntu.
I have a widescreen lcd laptop and the current resolution is set at 1280x768 pls see output of xrandr here for more information [url]
I want to change the resolution to 1024x768. I can do in ubuntu' display tool. The problem is that once I change it, the output does not take up the whole screen it has blank spots on the left and right side
For a better understanding please have a look at [url] and [url]
In open suse the system sets it at 1024x768 without any blanks on the left and right corner. You can have a look at it here [url].
My current xorg.conf is details is at [url].
Please also find my xorg.0.log at [url]
The lcd does not have any controls to tweak.

Under Gnome2 you were able to stop the OS from turning off the screen by selecting "never" as the time to turn off the display when the computer was idle. This was found under the screensaver configuration.The screen tool for Gnome3 does not offer "never" as an option. Does anyone know how to stop Fedora 15/Gnome 3 from turning off the display?

I just installed Mythbuntu 10.04 and have my Sony LCD TV connected via a DVI to HDMI cable. The issue I am encountering is that everything works fine until I turn off the TV and turn it back on later, because the screen stays blank and from what the TV tells me there is no signal. I have no idea what can cause this. I checked the TV settings in terms of power saving and turned it all off. I turned off the screen saver in Ubuntu, but still the same issue. My motherboard uses the ATI HD4200 onboard graphics engine

my laptop is running Slackware64 13.0. Today I tried to update to X.org 7.5 (version 1.7.1) from version 1.6.3 shipped with Slackware. I downloaded the relevant source tarballs from www.x.org and compiled them with no errors. The compiled packages are:
xorg-server-1.7.1
xf86-input-synaptics-1.2.0
xextproto-7.1.1
xcmiscproto-1.2.0
[code]....
My laptop has an NVIDIA graphics card and I'm using the proprietary driver from NVIDIA. Thus I reinstalled the driver after the update and tried to launch X.org with "startx". After a short while the NVIDIA logo appears for some hundred milliseconds and disappears then. But now the screen is blank and it is not possible to switch to another VT via Ctrl+Alt+Fx. But it is possible to login from another computer and restart everything, so that I conclude that the system does not hang.
It is even possible to do work normally with the laptop from remote. If I try to kill the X-server, it ignores SIGTERM and has to be terminated by SIGKILL. But the laptop's screen stays black and empty and does not allow to switch to another VT (chvt terminates with "interrupted system call."). dmesg does not give any errors.

I'd like your input on this. A toshiba laptop screen goes blank after few seconds(from turning on).
At first i thought it was fan that was out and once it got hot enough it cut the laptop off like my old Acer did.
But after close examination i noticed that it continues working. HD still spining and fan blows..
Example: Turn on>Hit F2 to go in to Bios> Bios screen appears>Before i have a chance to do anything it geos blank but continues working> I hit Cntrl ALt Del> it resets and screen comes right back up>second later it goes blank again.
ALSO the toshiba logo and whole screen seems to have a red tint to it.
I also get a media test error but that is likely from hard drive not being there during some of the tests.
DO you think it can be an LCD Backlight issue? or possibly video card?

Been trying to setup my xorg.conf file to have a 1920x1200 screen.Strange behavior: when my X starts up, I see my mouse cursor, can move it around. It's small enough to suggest the 1920x1200 resolution took, is working.However, the rest of the screen remains black. No login prompt.I've looked at /var/log/xorg.conf, no errors.Is there something else I can look at?

I have set up my Ubuntu virtual machine and am trying to adjust the screen resolution because it's stuck at 800x600 presently and there are no higher resolution options. I've looked at numerous similar forms and tutorials online and they all seem to involve editing /etc/X11/xorg.conf. However, for whatever reason, this file seems not to exist on my machine. I found another tutorial on how to add a screen resolution using xrandr --addmode which added the resolution I want to the list that appears when I type the command xrandr, but when I try to apply it I get an error about CRTC 262 failing.

i have noticed that if vista is not the active partition, hybernate does not work. it just goes black and then back to the user icon screen to log back in. another "slight" problem was that i was not able to apply a service pack. after restoring vistas dominance i was able to install the pack. is there any other work arounds for hybernate? even though you might not be interested in cleaning up after microsoft.

I disabled KMS and checked for direct rendering with the glxinfo command. glxinfo, reported that direct rendering is enabled. This is good news, because it means that the i915 driver is being used.

Now, I need to write a custom xorg.conf file to force X to use the native resolutions of my chip.

My problem is basically that when I boot for the first time after a fresh installation and setup, I am always stuck at the login screen or thrown back to it. No matter what account I log onto, whether it's 'root' or any other user account I have setup, it would attempt logging in, black out the screen, turn my monitor off then on again and I'm back at the login screen. This is all using the graphical interface of course. I'm having this same problem with all the linux distributions that I've tried so far:
Gnome Sabayon Mandriva 2010-I've even tried changing all the different boot environments, and same problem Open Solaris and Ubuntu won't even install. It just sits at the loading screen. Why would this happen? I've tried all these OS's on my regular PC, which is a dual core, 4 gb of ram, and they've worked perfectly. So why wouldn't it run properly on that other PC?

The problem is simple. On Karmic, I had this wonderful splash screen, and it was fully customized. But once i reinstalled at lucid (my computer's HDD fried and it was under warranty), I didn't even get the standard ubuntu splash. If Someone could help me to get the splash screen back, i can do the rest.

I have a Linux system running (Debian). It is working perfectly from a remote point of view. I can ssh in it, it has the imap running correctly, and a couple of kvm systems running (I can also ssh to them). Well, it works!
But when I go in front of the keyboard/mouse/screen there's nothing. No way to switch between the consoles with Ctrl+Alt+F# (X is not running on this system). The screen is desperately black. But the screen does not go to sleep mode, it still has its green led on! I guess it means that the graphics card still sends the H and V syncs correctly (VGA connection).
Is there a process that is blocking the display and prevents me from getting the control?
Note: Last time I used the console, it was in console 1. Ctrl+Alt+F1.

When I start up my computer Xubuntu is asking me to login (which is strange as I have login disabled). Then, when I do enter my password, it is accepted and after a few screen changes I am returned to the login screen. (I know the password is correct as the login screen informs you immediately if you enter it incorrectly.) Also, I can see that my display settings have been changed--the monitor resolution is wrong--my cursor is way big as are buttons, text etc..
