If power fails in the site and generator/UPS has it's last leg of power, how would I know if im away that something's about to go down? Is there a way for me to setup some alert to myself that we have just lost power in the site and everything's running on batteries? Is there a hardware of some sort that I can setup to send sms/call alerts to certain admins?
View 2 RepliesI am running a server that is mostly headless, but does run the Gnome environment (I have ubuntu-desktop installed). I usually administer it via VNC over SSH. My problem is that when I reboot the system over SSH, the system fails to fully load the GUI, which prevents me from connecting via VNC (although SSH still works).
When I connected a monitor and rebooted, the system booted up fine. It appears that the GUI will not load without an attached monitor, which never happened before in previous Ubuntu versions. I do use many commands but prefer a GUI for certain tasks and visualization of my work since my system has the resources to spare. Running Lucid Lynx
I am using Ubuntu 10.04 64-bit and I purchased a new ALFA AWUS036H wireless card. I would like to know if this "1Watt" wireless card is configured for full power. iwlist wlan0 txpower results:
wlan0 unknown transmit-power information. Current Tx-Power=27 dBm (501 mW). It appears to me that I should be able to increase the power. "iwpriv wlan0 highpower 1" does not work. Do I need to patch the new default driver that comes with Ubuntu 10.04 64-bit with the aircrack one following these directions:[URL]...? Monitor mode and a injection tests seem to work fine with the driver I have installed.
After a power outage Ubuntu fails to boot. How can I resolve this ? Is there a safe mode method to resolve the booting problem?
View 8 Replies View RelatedI've got an OLD computer I'm using as a server, the thing does not support ACPI, so we're in APM-land. The thing works fine w/ Debian Lenny. I have apmd installed and my /etc/modules file has an apm entry in it. It does a powerdown and everything is happy. I don't even need to add an apm entry on the kernel line in my menu.lst file. Then I decide to upgrade the box to the testing (squeeze) branch, making the appropriate additions to my sources.list file.
And everything goes to hell with apm. I don't know if it's GRUB2 (grub-pc) or not, all I know is that I can't get a powerdown on the machine. I've done a reinstall, via a netinstall CD, twice to verify this behavior. I can't find squat via Google on this other than someone else mentioning that the upgrade to GRUB2 killed apm. While I can just reach over and hold the power button for a few seconds to get a powerdown, I assume that every problem is solved by a simple entry in a config file.
Im trying to find out if my computer is whats got my power bill so high. Im not sure it is, but Id like to know if there is a shell command to monitor my power use.

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).
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 2 Replies View RelatedI 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.
I have observed a problem twice now with Apache trying to restart but hanging somewhere in the process. This happens after a power failure; the machine comes back just fine, but not the web server. The machine is on a UPS, but occasionally it runs out of "juice" before someone can get to it (we have a generator for emergencies). When this happens, a ps indicates about three processes running that are trying to start Apache, but they just sit there - this time for three days since the power failure was on a Friday. I can fix this by killing those processes and doing an Apache restart - but that takes human intervention, which is not acceptable.
I suspect this may have to do with SSL, since when I do a manual restart it asks me for the SSL password. There must be some way around this so the system can recover on its own. This system's web site runs under SSL since it maintains medical information that must by law be protected. But it also could be life-threatening to someone if the system can't come back and as a result a person can't get help.
So I would appreciate some guidance as to what I could change that would allow for system recovery without intervention. I'm happy to provide any configuration file info, if you tell me where to look.
I'm very new to Linux and recently setup a desktop PC with Puppy 5.2.5. only. I chose to have a permanent install on the hard drive and loaded additional PETS and utilities as I thought needed for my use. Last night after immediately booting up the PC I had a power cut lasting a few minutes. When power returned and I repowered the PC, I found during Puppy's boot sequence it reported an error and remained in what appeared to be a console mode - did not carry through and load my desktop. So I inserted the Puppy CD and booted from that but I'm afraid I'm not familiar enough with Linux to understand how I can get back my original desktop setup and run once again from my hard drive without having to go back to scratch.
View 5 Replies View RelatedI'm trying to get my screen to turn off whenever I lock my screen. I know that in Power Management, there's an option to turn off the screen after a set amount of time, and I know about xset dpms force off, but the former doesn't allow me to turn off the screen from the logout menu, and the latter only turns the screen off for a short amount of time (1 minute or so. The screen just turns back on by itself).
Is there a script I can modify to change what happens when "Lock screen" from the logout menu is selected, or is there a script I can add to the panel to lock the screen and then turn the monitor off (and turning it back on when I shake the mouse or something)?
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 Replies View RelatedI'm going to reformat my external drives to get rid of the crud that I've built up. (Crud being incremental backups, windows software, and similar things.)(I also want to get rid of the FAT32 file system that they use.) These are USB 1TB drives. The theory is that data is written to it once, but read back a number of times. (I also burn that data to DVD. If there was software that could organize 5TB of data on DVDs, I'd be using them.)
I"m trying to decide whether to use ReiserFS, Ext4, or another file system. Basically, I want something that:
* Won't get corrupted when the power fails;
* Can handle files that are 4+GB in size;
* Uses extends --- preferably without user intervention;
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.
View 6 Replies View Relatedwhen 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 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.
I have a small problem on my Compaq Evo Centos 5.4 web server. The web server runs just fine, the problem is it fails to restart from a power outage. Simple edit the BIOS. No! For a reason I can't think of the keyboard stops working after a few key strokes following the F10 to enter BIOS setup. Then its a power cycle. If left to BOOT the PC and keyboard are fine. After hearing about viruses which get to the BIOS I will ask can NIX get that far so I can adjust the Power ON?

$ gtf 1280 768 60
then I copy the result and type

View 3 Replies View RelatedI 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?

I use Squeeze with Xfce. My problem is that recently (after the xfce updates) the xfce power manager doesnt react to the power button - it is set to suspend. I dont have gnome-power manager or anything like it running.
If i reboot the computer, the power button will work but if i suspend and resume, it doesnt work again.
The computer is built on an Asus M3N78-VM mobo (2GB RAM/Athlon3200+ single core).
acpi_listen detects the button press.
Any thoughts?
I'm looking for any power monitoring devices for Linux to allow monitoring power quality, voltage changes, and outages. This would be for North American three phase power system. I want to have this data fed live to my own program. It should be something much better than just jury-rigging a circuit to fee the power waveform into 2 or 3 audio cards.

probably the power-supply or what?
If it is the power supply, how do I find new one as I've never had to replace anything on it or any other PC?
Also, I really need access to the hard drive but it's a weird hard drive and was wondering if I could put that hard drive in my K7 PC, which already has 2 drives in it can a pc have 3 drives? do I have to add/have another ribbon cable for 3rd drive?
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 RelatedWhen in my Fedora 10 I power off the system, by using the gnome icon or even the command line "poweroff", it shut down the machine and power off it as expected - EVEN THE NIC. I can see its led is off ! This happens when I put the machine in hibernate mode too, but not in suspend mode. When I power on and and power off it just after the POST messages, when grub is waiting a key to select an option, I can see the NIC's led is still blinking at each second or so. When I power on the machine and select windows (dual boot system) and then power it off, it power off as expected, I mean, it leaves the NIC on - the led blinks even with the machine powered off. As result, I can't wake up my machine remotely by using Wakeup-On-Lan since the NIC is powered off by Fedora.
