Ubuntu :: Any Way To Disable Display Dimming On A/c Power?
Feb 23, 2010
So my display keeps dimming on even when plugged into the charger.The option to dim display is unchecked in power preferences, it gets really annoying when I'm trying to watch a movie.
I tried to achieve this by disabling 'Enable display power management' checkbox in the 'Configure Desktop -> Display -> Power Control' KDE configuration dialog. That didn`t help and display still goes into standby mode after some period of inactivity. Also, I tried to disable dpms functionality by calling 'xset -dpms'. That didn`t help too. Note that 'xset dpms force standby'
is it possible to disable screen dimming while VLC is running? Because it keeps dimming my screen after 10 minutes while I am watching a movie without moving a mouse..
The display becomes less bright when on battery than on AC power, but I already unchecked "Reduce backlight brightness" on the power management setting. What else can affect the brightness?
I'm using Gnome as my desktop environment in Debian stable, I have previously address this issue at another post with the solution of setting xset command to disable screen blanking. However I'm still looking for a method that can automatically disable screen fade while watching videos in a browser. I don't want to permanently disable the powersaving idle method. I have both cpufreqd and laptop-mode-tools to conserve my powers.
I 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 wanting to completely disable Power Management, can I do it through the GUI? I am a former OpenSuSE user & am use to YaST. So it is a little hard finding ways to edit some settings.
I have Lucid Lynx with Gnome and Kernel 2.6.32 installed. Which probelms can I get if I disable Power Manager (Power management daemon) from the startup?
BTW does Code: xset -dpms s off do the same thing like disable Power Manager in the Starup Applications or DPMS is just for the Monitor?
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 ?
Under "Power Management Preferences" > "On Battery Power" > "When battery power is critically low" : We have several options : Suspend, Hibernate, Shutdown; but we don't have the do nothing option.Does any one know if i can disable all these actions so the computer will do nothing when the battery power is critically low? May be by a terminal command?
I need to disable the automatic power-off on shutdown so I can just withdraw the power myself. The reason for this is that the machine should power on itself when it gets power (which is accomplished by Resume on Power Failure in BIOS). I learned that I can turn off ACPI and APM by using the corresponding boot command options. Does this have any negative effect other than disabling standby etc.? Is there another easy to accomplish solution for this problem (maybe using linux from a readonly partition and make sure all programs are closed before I withdraw the power)?
running PCLinuxOS 2009.1 on my main machine : AMD Phenom II 545, 3GB DDR2, ATI Radeon HD 4870 512 GDDR3, 1 x 250GB IDE, 1 x 1x 250 GB SATA, 1 x 160GB SATA, 1 x 500GB SATA.What I want to disable are the HDD's powering down after a while because when I come back to work at my machine, it is painful to wait for the HDD's to spin up again. I also want to disable the screen from turning off. I have removed DPMS from myxconfig, but it as made no difference.
I've just installed openSuSE 11.2, and I need to disable the feature that causes the laptop to suspend when you close the lid (and it's plugged in to the wall). I've already done this for my user profile, and I've attempted to do it for the root profile, as well, but when the GDM login screen is shown, the laptop still suspends when you close the lid.
I am having a weird problem where if I don't touch the mouse or keyboard after logging on, the power manager settings are being ignored. I disabled turning off the display and screen saver from the Gnome utilities, but after about 20 minutes my screen blanks and my wireless network connection gets disconnected. This is on an HTPC, so I'm usually not near the mouse or keyboard, and unfortunately button presses from the remote control don't count. Media players like MPlayer will prevent the screen from blanking, but if I'm listening to music (where the music is served over the network from another computer), this means that the screen will go blank and the music playback will freeze as the network connection is lost. If I touch the keyboard just after booting it doesn't blank the screen or disconnect my wireless, but when I forget it's very disruptive.
I am running Debian Testing (Squeeze) with a Gnome desktop environment. I'm using gdm3 to log in, but I have it set up to automatically log me on. (I use gdm on my desktop, also with Squeeze, with it configured to show login screen instead of automatically logging me on and it still displays that behavior) I have attempted the following to resolve this issue to no avail:
Disable DPMS for my screen and monitor in /etc/X11/Xorg.conf Set all the timeouts for blanking, power down, etc. to 0 in /etc/X11/Xorg.conf Flat out disabling the DPMS extension. (so it's still blanking, even if it's not actually turning on power saving mode) Putting "xset s off" in ~/.xinitrc Disabling powersave with setterm in ~/.xinitrc Removing gnome-screensaver and gnome-power-manager from the startup items.
Edit: Actually, the wireless issue seems to not be related. It disconnected again, and after some searching with the error message I saw in dmesg, it looks like others have been having the same issue. It seems to have been coincidental that it was acting up when I was testing the screen blanking issue, and hasn't given me as much trouble lately, so it seemed like it was correlated.
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.
I am having a problem watching videos and such in 10.04 LTS, In power management I have display set to sleep in 1 hr but it is going to sleep every 10 minuets and prompting for my password everytime I make a mouse or keyboard movement. Makes it kind of difficult to watch a video.
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.
I am running openSUSE on Acer Aspire-One, 1.6/500MB/8GB and it runs perfectly fine on AC power but whenever I switch to Battery power (on 100% charged state) after sometime (3-5 minutes) the Display goes Black Dead while power light is still green and cpu fan still running and then i have to forcefully shut it down by press and holding power button and restart it.
This is really strange problem and i have fresh installed the openSUSE two times but same problem.
One of the PC having Ubantu gets disconnected automatically from the network.As we do in normal windows is that we get to the device manger and select the LAN card properties and check off the power management check box similarly how can be do this thing in a linux OS.
I have recently loaded Ubuntu 9.10 which runs perfectly, except for the power management system.I go into the GUI power management screen and tell it to use the screen-saver after ten minutes, but NEVER suspend/ hibernate but it suspends/hibernates anyway,sometimes after an hour, sometimes hours later.Is it possible to keep the screen-saver but disable the rest of the power management system?
im installing ubuntu onto a friends ibook, but am first running it live off the disk. it runs well, except for one thing, the display has a problem,i guess it seems like its tiled on the monitor, instead of fullscreen, it has a full desktop taking about 2/3 of the monitor, a sliver of the same desktop right below it, and a line of black to the right.
I've got a rather annoying problem with OpenSUSE 11.1 x86_64, I can't turn off the display power management! I've tried from the KDE 3 and 4 settings as well as GNOME, and finally YaST2. There's nothing in monitor's controls (the buttons on the monitor itself). The actual GUI controls in KDE/GNOME/YaST2 work (as opposed to being grayed out or disabled) and the system doesn't complain when I hit apply/OK, but every time I disable display power management, I wait about 15 minutes and sure enough, the screen blanks. I've checked and made sure the screen saver is disabled, I've looked for a setting to change in the YaST2 sysconfig editor and the kernel settings app, but can't seem to find anything. The only other thing I can think of is to try the acpi=off kernel boot option. I'd rather not resort to that. Anyone know if there is some super secret hidden setting somewhere that might be overriding everything else? Could this be some sort of ACPI incompatibility issue?
I am having an issue with my ubuntu server where it keeps dimming the screen i am using no GUI and i am wondering what the command or the file location that needs to be edited to stop this from happening.
Despite having the Gnome Power Manager set to put the display to seep after 30 minutes, it always happens after 5 minutes. The display will go blank but still lit, and then it powers off after the 30 minutes. Surely, if I set it to 30 minutes, the display should power off then, and not just blank after 5? I have no screensaver packages installed so it's nothing to do with that.
I am a brand new user coming from the MS environment. My impression of openSUSE is that it is like moving into a new house that is well built but the rooms are full of half-constructed self-assembly furniture and appliances without any specific instructions. Nor is it clear which does what and whether all are needed or not. There is a town hall down the road where fellow homeowners gather to discuss what each has managed to deduce about putting their own furniture together. The town hall has a sort of library where thousands of pieces of paper with instructions are stored in an ad-hoc filing system
My latest problem is that I have created a screensaver via the "Configure Desktop" application and set "Enable display power management" and set some timeouts.However, I seem to be asked for a password to unlock the screen when I come back to my computer. I have spent 2 hours trying to find the place where I can disable screen password locking but to no avail. I am perplexed and frustrated at how such an obvious function is so ****ed hard to configure. This is the impression I am getting of Linux in general - it is novice user-hostile and badly organised.
On the mbp 5,3 running 10.04, I'm trying to get the screen dimming keys working. Using the tutorial [URL] I followed the instructions for the nvidia-bl-dkms package. Initially upon configuration, the dimming keys work wonderfully, but after a restart, they don't work at all.
Installed 10.04 on a Dell Latitude D610. Found that the screen would start dimming after a few seconds of the computer being idle. Went into the Power Management Preferences to make sure that "Dim display when idle" was unchecked, and it is, both for "On AC Power" and "On Battery Power". Can't seem to figure out how to stop my brightness from dimming. Any help would be greatly appreciated, and any further information you need I will gladly provide.
