Fedora Hardware :: Monitor Not Going Into Power Save Mode

Jan 26, 2009

I have a Dell Precision T3400 workstation (Nvidia Quadro NVS 290) with the kmod Nvidia driver installed. Everything works fantastic for power saving, the screen saver comes on , then the monitor blanks after a while. The only problem is that the monitor itself (Dell E228WFP) never goes into standby. The power LED stays green instead of orange. Worked fine under FC8, only noticed it recently under FC10.

Debian Hardware :: Monitor Can't Go Into Power Saving Mode

Dec 27, 2015

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).

Ubuntu Multimedia :: No Display - Monitor Go Into Power Saving Mode

Feb 4, 2010

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.

Ubuntu :: Power Saving Mode (monitor Off) Complete System Freeze?

Nov 21, 2010

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).

CentOS 5 Hardware :: Kernel-xen 64bit And Ati ES1000 - Monitor Goes Blank And Says "no Video - Going To Power Save"

Nov 21, 2010

I have problem with onboard ATI ES1000. Server details:

Supermicro X7SBI, Q6600, 8G ram. Centos 5.5 minimal installation, without X.

Problem is that with all kernel-xen x86_64 from current kernel-xen-2.6.18-194.26.1.el5.x86_64 back to kernel-xen-2.6.18-128.el5.x86_64 after kernel boots monitor goes blank and says "no video, going to power save".

Google finds similar problems and sugestions was to add "nomodeset". With this option monitor also blanks after kernel boot, but says "out of range". Other options to modify xorg.conf does not apply, becouse there is no X installed.

I try with multiple monitors, without success. This happens only with 64bit kernel-xen. All other 32 and 64 bit kernels and 32bit kernel-xen works fine, video is ok. This happens to 6 servers, all are same hardware, used as cluster. Installation with "linix text" allways is fine, video disappears after first reboot when standart kernel is booted. I also tryed with almost all possible "vga=xxxx" kernel options and none of them works.

What else to try?

Fedora :: Power Management Doesn't Turn Off Monitor

Jun 15, 2009

I just upgraded from FC10 to FC11 (32-bit) on an old Dell laptop. I set my power management settings (in Gnome) to turn the monitor off after some idle period but always leave the computer running and the hard drives powered. I also set my screen saver to a blank screen. I noticed that the screen saver does come on (turning the screen black), but the monitor back lighting never goes off. I tried different idle times for the power management settings (I usually set it to 1 min, but some other posts implied that 11 mins might work). I should also mention that this is after I've logged into a user account, not sitting at the login screen.

I didn't have this problem in FC10 (the monitor would actually turn off) so I figured it was a bug in FC11, but I can't seem to find a thread addressing this issue. I've found some what similar threads, but none mentioning this particular problem.

Fedora :: 14 - Overriding Power Management Preferences - Settings Are Set To Never Put The Monitor To Sleep

Nov 17, 2010

I have an odd problem since preupgrading from Fedora 12 to Fedora 14.

My power management settings are set to never put the monitor to sleep, yet after a certain amount of time, lo and behold, the Fedora box has gone blank and I have to enter my user information and password to get back to my gnome session.

In the power management preferences I have "never" selected for both putting the computer or display to sleep.

In the screensaver preferences "Lock Screen After" is *not* checked. (And if I click "advanced" I also note that "Power Management Enabled" is also *not* checked).

I'd just as soon not have to "log on" to this machine every time I'm away from it for a while.

Ubuntu :: Odd Resolution - Monitor After Switched It To TV Mode Then Back To PC Mode

Feb 8, 2011

When I first installed ubuntu 10.10, the display was for some reason tinted green and shifted a few inches to the right. After experimenting with the resolution preferences, I eventually got it to a large resolution (1280x720 ... or something like that) yet is was quite blurry. I found out that the problem was with my monitor after I switched it to TV mode, then back to PC mode. It became perfectly clear! All I had to do then was adjust the screen positioning by shifting it left a bit.

Even though I have made the resolution I figured out to be default, whenever I turn the PC on after shutting down, it goes back to the "green-and-to-the-side" mode. :/ Ain't really a big problem, until I tried to fiddle with the resolution preferences s'more.

Somehow, I have set it to be twice as wide of the maximum my monitor can display, went back to being green tinted for some reason, and is completely shifted left (yet the right side is still visible) This means that I cannot see what is going on the left side, and cannot adjust the resolution preferences, nor can I click blindly cuz the border is only around my visible side of the screen. Now it is stuck like this.

I've researched many hours and eventually found the terminal command for the resolution preferences. it popped up on the visible side. Although it was to no avail cuz I HAVE TRIED EVERY SETTING AND OPTION and absolutely nothing changed. I assume a system restore would simply revert it back to the previous satisfactory settings, but the thing is I want to FIX it. I am new to this terminal stuff, so I want to learn it and all that. To put it simply, here's what I want:

Learn how to manually adjust resolution without depending on a simple dialog box. Make the satisfactory resolution default and consistent through turning it on and off. Link that could teach me the essential commands, all this googling is stressful. D:

Fedora :: No Monitor Input During Boot, Unable To Enter Text Mode From X Window

Nov 24, 2009

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?

CentOS 5 :: Stop Screen Blanking And Power Save?

Aug 25, 2009

I'm not sure this belongs in this forum as opposed to the hardware forum, but I do not beleive this is a hardware issue.I want to stop the scrren from blanking and going to power save. I'm running 5.3_x86-64 and I'm using the nVidia drivers direct from nVidia called NVIDIA-Linux-x86_64-96.43.13-pkg2.run.

So far, I'm added DPMS off in /etc/xorg.conf, removed all the screensaver packages and all the power management packagesbut the screen is still going blank after a time of inactivity.What else do I need to do? I can not allow the screen to go blank, there should be no screensaver or power management and the machine should stay in a completely awake and ready-to-use state at all times.

Ubuntu :: Save Power And Avoid Heating By Powering Server Off Durring Day?

Jul 5, 2010

I have a server that only runs durring the hours the house is asleep, to avoid bandwidth hogging. I know there are ways to prevent bandwidth hogging, but I figured I'd kill two birds with one stone. My other goal is also to reduce power and cooling costs. My two computers between them make a very nice space heater in the winter, in summer they make it sweltering in my room.I'm sure it would be trivial to get the sever to power itself off every morning, but is it possible to get it to power itself on at bedtime? If not, I do have Wake on Lan working, is there a windows program that would allow me to send a wake on lan signal every day and then shutdown windows

Ubuntu Multimedia :: Disable 3D (dri) In Lucid / Switch Off 3d Dri On Laptop To Save Power?

Jul 25, 2010

I want to switch off 3d i.e. dri on my laptop to save power. There is a bug in the intel video driver that makes it generate excess wakeups and thus increase power consumption. I don't use 3d so this is very annoying.

I have tried modifying /etc/X11/xorg.conf to insert an "NODRI" option in the "Device" section and have commented out both of the "load dri" commands in the "Modules" section. No go. When I look in the xorg log, these changes are seen but not acted on. The system appears to have hardwired defaults set somewhere which are difficult to override. It appears to be a new issue because with Karmic one still had control with xorg.conf.

Just generally I don't like changes like this because it is not documented on the wiki where and how to change the defaults in Lucid. Linux was supposed to be easily configurable so IMHO this is a step backwards.

Ubuntu :: Screen Doesn't Go Into Low-power Mode / What To Do?

Jan 26, 2011

I'm on 10.10 64 bit. I have my power management settings configured so that on AC power, after 0:30 the screen is supposed to go to sleep.

But the problem is that it never goes to sleep. The screen saver comes on after 10 minutes, as scheduled, but when I come back even after a long period of time, the screen hasn't gone to sleep (it hasn't gone into low-power mode).

Please let me know what specific config information I should provide to help debug this and I'll post it here.

Debian :: Text Mode Power Management?

Mar 16, 2011

I recently converted a Toshiba Satellite A75 notebook with a broken screen into a minecraft server that me and my friends will be using at UAB. It's currently running the latest version of Debian in text-mode with a few shell scripts that backup files and update a webpage at specified times.

The server runs fantastic ( though it's currently on my home network so no one can join it unless they are on LAN ) but there is a minor problem. I took a look at the backups from last night and it seems the server shut down around 10:00 in the morning because the laptop went into sleep/hibernate mode or something like that. I'm not sure what's causing this exactly but I think it's some setting in gnome-power-manager, but I can't run it in text mode.

Ubuntu :: Unable To Dim The Screen In Order To Save Power - Listen To Music Or Any Other Sounds Through Headphones Or Speakers

Jun 25, 2010

Ok so I am a total newbie at Ubuntu Linux and I'm having problems I don't know how to solve.

1.) Up until yesterday this wasn't a problem, but after a power outage while I was connected I am now unable to connect to the internet anymore as it says "Networking is disabled", how do i enable the "networking"?

2.) Another problem I am having is that I am not able to dim the screen in order to save power among other uses, I've looked around but haven't been able to find a solution, I am running ubuntu on a Gateway M-Series Laptop.

3.) Finally, since installing linux I have been unable to listen to music or any other sounds through headphones or speakers, when i connect something into the audio output, the outer speakers do shut off but no sound is emitted through the speakers/headphones, and yes i have tried multiple ones to make sure it wasn't the headphones or speakers.
