I'm using natty, and in power management settings the maximum time I can set to put my pc on sleep after being idle is 2 hours, how can I increase this time? I need to put it on at least 4 hours.

I have to questions: I am new with Linux and using ubuntu on my laptop computer. when i reopen my leptops cover after i closed it, meaning - putting computer to sleep, every thing is working, but the screen is black and nothing is seen. No matter what i tried to do, i cant make it to "wake up".
Using the computers battery, with no electric supply, the battery time is only half of what i get when using windows. i tried using less lumination but it didnt seem to help.
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.
On the last release, I had this app installed where I could pick my power profile. I could use power conservatively, and performance would suffer a bit, but longer batt life,or I could have it automatically detect, or I could have the apps use all the power they want and then some. I'm looking to reinstall that app. What was the name of it?I can't remember, and so far, can't find.
View 2 Replies View RelatedMy Ubuntu laptop's screen goes black in about 10 or 15 minutes. I went into Screen Saver setup screen. Timeout when computer is considered idle there is set to 30 minutes and black screen screen saves is picked.
Why screen goes black after only 10-15 minutes and not 30 minutes?
I have an Alienware M11x r2 laptop running Windows 7-63 and Ubuntu 10.10 Unity installed.It was all fine and dandy until I changed my grub timeout to 1 sec (or perhaps 0, its been so long i can't remember!) to reduce the waiting time until an OS boots.My grub was set to boot to Windows 7 as default.Now when I boot up I cannot halt the boot process not matter what key I press (e.g SHIFT).I am doomed to forever boot into Windows. Its been months and I had written off my Ubuntu OS but I am tempted to try and fix this one more time.Since I cannot access the Ubuntu installation AT ALL I cant use the usual ways to increase the timeout on the grub menu (yes I have searched the forums far and wide).
Is there ANY way of changing the grub menu parameters without actually booting into Ubuntu Unity? Can I modify the timeout settings using a live cd or usb boot?
How can I Increase time between sleeps? I have tried power management without effect.

I was not getting any error messages after restart. I should have powered down fully, but did not think that it would make a difference. :(
The same issue is again occurring, but after shutdown ONLY and only on the first boot. After the first boot, a system restart will not cause any error messages. (I have rebooted at least ten or twenty times to make sure)
But after a system shutdown, the first boot hangs up and I get the
"Red Hat nash version 5.1.19.6 starting hdb: timeout waiting for DMA hdb: drive not ready for command"
errors five or six times before each boot. Also the system boots very slowly the first time.
I used the getinfo.sh all command and posted the info to the suggested site here: [URL]
Is it possible this could be a hardware issue? This is an old salvaged HDD. Ive changed everything I c an think of in the BIOS with no results.
I have used the hdparm -d /dev/hdb command and verified that dma is not being used on initial boot or after a shutoff but IS being used after a reboot...
here are the HDD settings
/dev/hdb:
multcount = 16 (on)
IO_support = 0 (default 16-bit)
unmaskirq = 0 (off)

Alright this is not a huge issue but a rather annoying one. I hook my laptop up to my lcd to watch movies all of the time. The problem is though I have selected and reselected many times for the screen to not power off after so many minutes of inactivity. But for some reason it doesnt work. If i set it to an 1 it still like every 5 minutes turns off my screen. Im running 9.10 on a toshiba satellite with an intel graphics card.

When it is plugged in with AC Power, the screen fades black after a few minutes and locks up after about 10 minutes (shows a dialog for passwd when back).This gets really annoying when listening a movie or just reading text.System->Preferences->Power Management is set to "never" for everything.gconf-editor->apps->gnome-power-management is set to "0" for everything finishing with *_ac.

View 2 Replies View RelatedI just did a fresh installation of Kubuntu 10.10 on a laptop last night, which has a 1.6GHz Intel Core Duo CPU.
I was very disappointed to find that there appears to be no way to configure CPU frequency scaling in the System Settings. There were options for this in 10.04.
I prefer to have the CPU running at maximum speed when running on A/C. In Maverick, however, I have had to resort to installing cpufreq-utils, and setting the CPU cores to 'performance' from the command line.
I like this laptop a lot, but even many simple games run sluggishly if the CPU cores are not set to run at max GHz. (As a matter of fact, this machine is much more sluggish even with CPU cores running at maximum in 10.10 than was the case in 10.04.)
I wonder why such an important option would have been removed from the power management settings?
when i get the Graphics device driver on, then the power management not work. it can not change the CPU frequencies, and it can not change the LCD backlight and save the change. I try a lot, install laptop-mode-tools,and change thd setting, it still not work...

Ok, I am running a file server that can be accessed throughout the house. I was able to successfully wake from suspend and it works beautifully. Now what I need the computer to do is go to sleep after lets say 30 minutes of inactivity so that I never have to touch the computer and it will use minimal power until I need it.
Anyhow, I tried to set the settings in Power management and the only thing that happens is the display turns off. the suspend on the desktop works fine, I can type in sudo pm-suspend and that works fine. but the computer just wont go to suspend automatically by way of the power manager.
I have tried changing the /etc/pm/config.d/00sleep_module to say SLEEP_MODULE="uswsusp", but that only made the computer go into some crazy linux mode that I had to reboot from. I had to change SLEEP_MODULE="kernel" (actually, I left it blank as it is the default).
I also turned off my screensaver so there wouldn't be any confusion from that.
I also ran cat /var/log/pm-powersave.log and I got a long list with the following being one of the main texts that kept repeating. "/usr/lib/pm-utils/power.d/sched-powersave false:**sched policy powersave OFF"
I have a wlan0 which is Atheros AR928X and wlan1 which is Alfa AWUS036H
I thought I could set iwconfig wlan0 txpower [higher than 20] but any value more than 20 results in:
Error for wireless request "Set Tx Power" (8B26) :
SET failed on device wlan0 ; Invalid argument.
I get the same error for wlan1 when trying a value higher than 27.
Is there a way of increasing the TX power and if not then why not?
When I tell the computer to go to sleep and there is a power failure the sleep state is lost. Is there a way to prevent this? I already know about hibernate and I'm using it but sleep is faster and there is no complete loading of the computer (BIOS, Grub and so on) it just goes directly into the desktop. As far as I know the sleep state is done when everything is in RAM and the computer is turned off but the RAM sticks still receive power. Is this true?
P.S. Can this be done with hibernate and SSD drives? As far as I can tell from what I've read it will be the same but with no state loss. Is this true?
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
when I boot up ubuntu, the suspend and hibernate buttons will be missing and the alsa stuff wont work. When I select shutdown or restart or log out from the power menu ( the one that's missing the 2
buttons) it only logs off the user. I've tried reinstalling the kernel and updating grub for a solution to no avail. The only way to shutdown the system when this occurs is through a sudo halt command in terminal. I may have to use the command a few times until the computer will boot with sound and all of the suspend/hibernate buttons in place.
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 having some serious speed/connection issues with my laptop's WiFi card, and it has been suggested to me to disable power management for it, just as an experiment. However, when I run "sudo iwconfig wlan2 power off," I receive the error:
"Error for wireless request "Set Power Management" (8B2C) : SET failed on device wlan2 ; Operation not permitted."
I am running 10.04 on an Acer Aspire One
Since my upgrade from Lucid my battery icon displays permanent full charge even when running without AC power. When the battery runs out, this leads to an immediate violent shut down, everything dies at once.

I've recently installed Ubuntu 10.04 and found the following problem: power management doesn't appear to be working. If I'm away from my computer for only a few moments, the screen is on dim when I return and I have to log on again. I've set the following states in Power Management: NEVER SWITCH OFF SCREEN and haven't ticked the DIM WHEN IDLE BOX. Can anyone help with this problem - it's infuriating. Meanwhile, I've gone back to Ubuntu 9.10 ...
View 2 Replies View RelatedI have selected to power down the monitor after 30 minutes, and suspend the computer after an hour. It does not work. With Beagle not running (more below), the monitor powers down after 30 minutes as expected. But then later (probably after an hour?) it powers up again and stays that way. Not exactly what I envisioned.I have removed Beagle from the set of running processes. The process list ("ps ax") shows Beagle as a serious consumer of CPU time, far more than any other process. (At termination it was at 500:00; the next most hungry process was /usr/bin/Xorg at 10:00. Most barely get over 0:01.) It introduces these problems:
1. after some amount of system idle time (it is about 5 - 10 minutes) Beagle starts consuming vast wodges of CPU time. I have dual core AMD 5200; both CPUs run up to about 70% usage until I do anything, like move the mouse. Then the usage drops back to the usual 5 - 10%.
2. When Beagle is thrashing the CPUs, the power management monitor thinks the system is busy. And powers down nothing.
I've attached a UPS to my server through USB. and sure enough up came a tab in Power Management Preferences for the UPS -- great.
There are power low options as follows:
"When UPS power is low"
"When UPS power is critically low"
The UPS sends a message to the computer when a threshold you set in the UPS is reached, in my case 25% of battery left.
The obvious guess is that this warning from the UPS is the "When UPS power is low" however, I don't know. It's just a guess.
Looking further at the data I can get from the UPS the battery data is as follows:
battery.charge: 100
battery.charge.low: 25
battery.charge.warning: 50
battery.runtime: 760
[Code]....
However, again, that's just a guess from what would make sense.
So my first question is, is there a way to know this information, and is there a place were these critical points are set, or are they all from the UPS. I'm guess there are some settings somewhere because not all UPSs are going to be able to supply this information. Some may only supply a battery level or some just a warning message so there must be some configuration for this somewhere.
My 2nd question is a probably a little harder to know the answer to. After getting this to work I wanted the added functionality of nut so I installed it and got it working and it uses the On UPS Power panel as far as I can tell.
Through all the nut documentation it talks about powering down on once the battery level reaches the critical point (I assume that is "When UPS power is critically low"). I don't see anywhere however where it mentions handling "When UPS power is low" so now the question comes up, will it have any effect at all with nut installed, i.e. what will happen?
Of course I can just "pull the plug" and start finding this stuff out but Linux is all about having the information and "knowing" (assuming all works as it should) I am asking to find out where this information would be -- and become smarter for it
I'm fairly used to working with Fluxbox.There,if I want to let myself suspend the computer, all I have to do is add something like Code:[exec] (suspend) {sudo /usr/sbin/pm-suspend}to my .fluxbox/menu and it works like a charm, after having added me to the sudoers. I nstalled openbox earlier today because I was having some font rendering issues in flux and I've been trying to find a way to add something similar to my menu without success. I added this to .config/openbox/menu.xml:

I've got a new netbook - Dell Inspiron mini 1011. I have installed slackware 13 on it. According to dell's website its battery should last up to 9 hours:Quote:Mini 10 offers up to 9.5 hours of battery life1 to keep you on the go.I understand that it depends on a variety of factors and these are just testing estimations that will probably never be achieved IRL.For 95% of the time I don't run X on it. Just emacs (gnus), nethack, elinks. If I do run X, it's fluxbox. The average battery time is 2hrs - 2.5hrs. I understand that Slackware 13 is not designed specifically for netbooks, but 2hrs is way off the 9-hour estimation. Either the battery is faulty, or it's the power management issue. Before I deal with the battery, I'd like to ask you for some suggestions on improving the power management. The acpi and acpid are installed on the system. Are there any packages that would improve the battery performance? Or perhaps some config options?I believe that recompiling the kernel would improve it, wouldn't it? What options I'd have to set/unset?P.S.Unfortunately, once I checked the netbook is ok, I removed WinXP that came with it, so can't compare with it.
View 14 Replies View RelatedThis is very likely a silly question but .. where is the power management setup in KDE? I have set it up before in Slackware 13.1 but now that I'm running 13.37 I'd like to set it up again but can't seem to recall where to set it up.
View 2 Replies View RelatedI am having several problems with what i believe to be gnome-power-management. Power management will randomly say that either i do, or don't have a battery. This means that the icon in the notification area does not appear, and I can not access the settings for on battery power. also, when i tell Ubuntu to suspend, it just goes to the screensaver and nothing happens. conky is still able to read the battery just fine, its power management thats having problems.

Makes it kind of difficult to watch a video.
View 3 Replies View RelatedWhatever settings I use in the power manager, (Ubuntu default Gnome Power Manager) nothing appears to change. Screen brightness does not change when moving the slider, but is reduced after 5 or 10 minutes (haven't timed it. Probably whatever is default) of inactivity, even though the reduce screen brightness checkbox is unchecked. The latter is pretty annoying when watching online TV streams, especially since the video also exits full screen mode when the screen brightness is reduced.
The weird thing is, as the title implies, that when booting in recovery mode with FailsafeX the power settings seems to work. At least the screen brightness varies as the slider is moved I should probably mention that it is possible even in normal mode to adjust the screen brightness by using the buttons for adjusting screen brightness on my laptop (Fn + arrow up/down)
