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.
View 2 RepliesI'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).
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).
View 1 Replies View RelatedI work on Ubuntu 9.04 and our application requirement is not to go to power saving mode when application is running. I added ServerFlags section to /etc/X11/xorg.conf
Section "ServerFlags"
Option "blank time" "0"
Option "standby time" "0"
Option "suspend time" "0"
Option "off time" "0"
EndSection
This didn't help. Then I tried following commands
gconftool-2 -s /apps/gnome-power-manager/ac_sleep_display --type=int 0
gconftool-2 -s /apps/gnome-screensaver/idle_activation_enabled --type=bool false
I see that it works fine only if I change settings via Settings>ScreenSaver>Power Management in gnome. I wan to do this via script. Can I do this? Which file gets updated when I change display settings via Settings>ScreenSaver>Power Management.
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 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.

View 4 Replies View RelatedI have a Dell monitor attached to a Dell laptop. I am using Ubuntu 10.04 x64.
Spec:
Latitude E6500 : Intel Core 2 Duo P8800(2.66GHz,1066MHz,3MB)
Base Options : 256MB Nvidia Quadro NVS 160M Graphic Card 1 S
Display : 15.4in Widescreen WUXGA (1920X1200) 2CCFL
Dell 2001FP (attached using DVI)
When I try to boot into Ubuntu with the monitor attached I get a DVI: Cannot Display this Mode message on my monitor. I can boot into Ubuntu just fine if I detach the monitor. Have tried with VGA, but to no avail. I have the latest and greatest Nvidia drivers downloaded from the Nvidia web site. Googling indicates that this is a Dell problem, however, I am not sure about this. It worked just fine on my previous laptop (IBM T61) and Ubuntu 9.10, so I guess it has to do with the laptop and not Ubuntu 10.04.
I am posting this to hear if there are others with display issues on Dell E6500 laptop with the Nvidia Quadro NVS 160 driver. This problem is starting to annoy me a great deal, but I am uncertain how I should move forward. In short; I have Ubuntu 10.04 x64 installed on my Dell E6500 laptop. When using only the laptop, everything works great. The second I plug it into the docking station (the laptop lid closed) and want to use my two external monitors (Dell 2001FP) I'm in trouble. I cant see anything and what I get is a 'DVI: Cannot Display this Mode' on the primary monitor - If i try a regular VGA cable I get nothing but a black screen.
I have played around with the Nvidia config but it cant find my monitors and therefore I cant do much. I am aware of the various "hack the xorg.conf" options, but I before I do that I wanted to see if others had experienced the same thing. I had hoped that we were pasted the hack stage and that primary functions such as display would work by now.
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!
View 3 Replies View RelatedI recently installed the first non-virtual Ubuntu server in our office (to put it in perspective, it's outnumbered several to one by Windows servers). It had an inexplicable array failure, and now it's been retasked to run VMware Server for testing purposes since we don't trust it at the moment. For the sake of ease of use, on this server I decided to install Xubuntu desktop x64, rather than Ubuntu server as I've done with a couple others.
This server is on an old school 8-port Linksys PS/2 KVM. It's got a CRT monitor in the middle of a rack of somewhat aging equipment. The problem I'm having is somewhere between the KVM, this old monitor, and some power saving... when Xubuntu tries to put the monitor in standby, instead it gets this vertically scrolling garbage. The Windows servers in this rack don't have any problem putting it to sleep, but I figured I might as well just turn off DPMS on this particular server.
So I logged in via SSH, stopped GDM, generated a /etc/X11/xorg.conf, and changed Option "DPMS" to Option "NoDPMS" which according to the manpage should take care of it. I also changed the GDM video mode with this xorg.conf so it's definitely being used. Following some other suggestions I found in my search, I issued "xset s off" and "xset -dpms" but this hasn't disabled monitor power saving either. I've been restarting GDM each time I change something. 5-10 minutes later it's scrolling garbage again. What's it going to take to turn off monitor power saving at the GDM logon screen?
I am on Lucid 10.04 with Nvidia 9600m (v195.36.24) My TV is 1280x720, my Laptop is 1600x900 (Closest setting to the TV is 1360x768 ). I plug my laptop to my tv via an HDMI cable. I press F1 to get into my presentation mode, and the tv shows most of the desktop, but not all of it. Is there any way to conveniently make it so it automatically sets it to 1280x720?

I am planning to make a home made NAS running ubuntu server 10.04 LTS. Nothing fancy, simple samba with open access for all and openssh for admin access over the network. The NAS will not have heavy traffic, two home computers with occasional access, just to serve as central location. I am in doubt which CPU to use and I am after both budget and power saving solution.
1. I have an old Athlon Clawhammer I can use but the TDP of 90W is putting me off. I can also use existing 2x512MB DDR-400 memory with it. The board would be new.
2. I would rather invest in new mini-ITX board with built-in dual-core Atom D525 (TDP 13W), VGA and Gb ethernet. I would add 2GB DDR3-1333 memory.
Since I would need a new board for the Clawhammer too (current one doesn't have SATA), I am more attracted to option 2. Would the dual-core Atom be enough running this simple home NAS? I think it should but my experience with ubuntu server is limited.

I also want to disable the screen from turning off. I have removed DPMS from myxconfig, but it as made no difference.

I am using Xubuntu 9.10 on a nettop as a X11 terminal.In order to do that, I created a custom session script that runs some commands instead of starting xfce4-session and the likes from GDM. When I boot this nettop, GDM automatically logs a dummy user in (called "test"), and runs a script that does "xhost +", and opens a small X Terminal to keep the X session alive, while some other computer sets the DISPLAY environment variable to point to <nettop>:0 and runs gnome-session.
My trouble is that after 10 minutes of idle, the screen is blanked(power saving I presume).
I tried to add "xset -dpms" and "setterm -blank 0 -powersave off" to my startup script, in vain. I want my power saving options to be configured on the remote computer, not the nettop. How could I prevent X/GDM/Whoever from blanking the screen ?
How could xorg be set-up such that different monitors work with different DPI but still compose the same extended display?
I have a 15 inch laptop display extending to the right the main display which is 23 inch. The resolutions are comparable, but the difference in pixel size is very large. Thus, either the external display has too large fonts and UI, or the laptop one has them very small. Moving them at different distances is not entirely possible.
xrandr info:
eDP1 connected primary 1920x1080+2048+0 (normal left inverted right x axis y axis) 344mm x 194mm
VGA1 connected 2048x1152+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
I heard that Windows has a hack (which I can't check) for extending displays with different pixels sizes: it computes in which of the displays a window has most of it's surface and sets the DPI for that window based on that. Thus a window will change DPI when crossing monitors, (and will look too small/large on one of the monitors if it is in the middle).
I have an ASUS 1000HE laptop running Lucid 10.04 (Desktop not netbook version) which I have connected to an external display (LCD). I don't intend to use the laptop by itself anymore therefore I have configured the display properties to turn off the laptop display and use the external display as primary. However, when the PC enters 'locked mode' or the display powers down after a defined period of time (as set in the properties) when I wake the PC and the display, it turns the laptop monitor back on .... switches the laptop screen to primary display (i.e. with the panels etc displayed on it) and extends the desktop to the external display! The only thing I can then do is go back into the configuration utility and turn the laptop monitor off again and boom, everything is fine and dandy displaying on the external display again! I don't really want to have to do this every time I come back to the PC after it has been locked nor do I want to write a script (if it can be avoided) to deal with it!
View 2 Replies View RelatedI have a Radeon HD 5830, running 3 monitors on 10.10 64bit with the 10.6 video driver. The three monitors ( from left to right ) :
DFP1 : 1152x2048
DFP2 : 1920x1200
CRT1 : 1360x768
The problem I'm having is getting the middle monitor to be the primary one.
Running
xrandr --output DFP2 --primary
puts the panel on the middle screen but my docky and icons stay on the left screen. Flash videos also open up on the portrait left monitor which looks awful. Ideally I would like the icons on DFP1, docky on P2 and flash videos to open on P2. But I would definitely settle for everyone to be on the middle screen and drag it around as I please.

I am running openSUSE 11.2 x86_64. I am processing work units from Folding@home on this pc. Strange thing is, when I actually leave the pc alone and working on folding@home, my performance actually drops instead of going up as I would expect. I believe there is some kind of powersaving feature I cant find or something else that's hurting quite a bit on the PC. I am talking about maybe 20-30% performance loss. PC in question is: Athlon II 630.
Already deactivated Cool'n'Quiet from the BIOS. Got no fresh ideas on what could cause this weird behaviour.
Update:
Code:
[22:05:52] Completed 260000 out of 500000 steps (52%)
[22:18:28] Completed 265000 out of 500000 steps (53%)

PC was "idle" working on folding and I came back at 54%, see the huge difference? Frames were taking about 13 minutes each when "idle". When I am using the computer, frames are done within 8 minutes.
I asked this question in the installation forum and got as far as possible with the advice there. I'm using a 32" Insignia TV as my sole monitor. I'm using the HDMI from the integrated video on my ASUS E35M1-M motherboard. I have it running at 1920x1080. When it boots up the monitor says the BIOS is running at 1080p, but as soon as Ubuntu loads the TV switches to 1080i. When I was setting the computer up the other day it was running 1024x768 and the text looked beautiful, now similar size text is blue/black and scraggly/shadowy looking. I followed some instructions for xrandr, but ran into problems and the person giving me advice admitted he was too unfamiliar with xrandr to get me any further. Here's as far as I get:

I run Ubuntu Netbook 10.04 on my EeePC 1005HA. I'm going to get a SSD for it eventually, but I can't afford one right now so it's running from a 200GB hard disk I scavenged off a dead laptop.
I went in power management and set the option that says "spin down hard drives whenever possible", but this accomplished a whole lot of nothing - whenever the computer is on, the drive's spinning. I ran hdparm -y and the drive clicked off, and then promptly spun back up after a few seconds. Iotop shows occasional tiny bursts of activity from "jdb2/sda1-8", which I don't really know how to interpret, but I don't have anything weird installed so I'm assuming this is normal system operation.
Now, what I need is some sort of application, utility, command - anything - that forces the computer to keep all filesystem changes in RAM with the drive shut down; every five/ten minutes or so (this would hopefully be configurable) it spins up the drive, dumps the filesystem changes to it, and spins it down again.
I realize this presents data loss risks related to crashing and poweroffs when the cache hasn't been dumped to disk, but I'm willing to risk it as Linux never really crashes at all, and since it's a netbook power failures won't cause unexpected shutdowns.
My brother has just installed 9.10 on his Inspiron 6400 and would like to have a dual screen setup using both the laptop display and a flatscreen attached to the VGA socket. Using the standard display options, the two displays are recognised and when the 'mirror screens' option is disabled then settings applied it works to the extent of allowing the cursor to move between the two monitors; however the monitors display nothing except a black screen and the cursor.
I've updated everything to the current version, had a look for restricted drivers (none are suggested by the GUI tool thing) and checked both displays work (both independently and as mirrored). I also had a look for an xorg.conf to poke around in but there wasn't one there.
I've covered a little of the exploration of this in another thread here. Unfortunately no replies.I've now installed as many power-saving features as I can get to work including laptop-mode scripts and my Asus Eee PC 900 has the battery lifespan of a gnat (2 hours 39 mins of extremely light usage including a long period of inactivity although with wireless turned on, from fully charged to battery cutting out, annoyingly this time ignoring my script that registers a critical battery APCI event and shut it down safely).
So, basically is my new Asus Eee PC 900 the worst designed netbook ever, or is linux just not supporting it's power-saving features? It is actually the version that comes with Asus's own linux distribution on it, but I've installed Arch.
[Code]...
What then are the power-saving options left available to me? How can I extend my battery life to long enough to check an email? What out of what I've said ins't working that really should?
I am trying to figure out why, i need to restart/reboot ubuntu in order to reconnect wirelessly after being in power save mode. It works fine before the power-save mode and fine after the restart. Is it an IP issue?
View 1 Replies View RelatedWhen 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:
So I've come across several tips to optimize battery life on Linux. [URLs]. In addition to undervolting, I would like to underclock. Is there a way to control CPU speed outside of the BIOS via some software control in Linux... or some sort of boot manager? I would like to boot to linux using underclocked speeds and have Windows running full blast. Is there a way to run Linux completely in RAM? I have read that saves on power consumption from the hard drive.
