Networking :: WOL Is Not Working After A Software Power Off?
Apr 15, 2009
When 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.

i was able to mount my SMB shares, but I didn't actually try to transfer data. I tried to move some data off my linux box to my mac, but i got a finder error 36. which i believe is a input/output error. I got further proof of that when i was going through some directories and got this: ls: reading directory .: Input/output error so i'm gonna guess that whatever input/output errors are happening is what is causing AFP and SMB to not work properly.

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 much research, I have found the solution to my intermittent wireless problem!Whenever the laptop is plugged into power, wireless is perfect, when I'm on battery, wireless is horrible.Here is the fix:
Code:
sudo iwconfig eth1 power off
Unfortunately, I have to type this in everytime I unplug the laptop.

I'm using Fedora 12 with LXDE (sudo yum groupinstall LXDE if you want to try it), and while using LXDE rather than GNOME, the power button doesn't do anything. I found a possible solution here: [URL] but I have no /etc/acpi/ folder. Why is that? Package acpid is needed.

When I change the "Put display to sleep when in active for" it seems to make no difference. The screen goes to sleep when it wants. Some times in the middle of watching a dvd (after about 10 mins when it is set to 1 hour).Could this be done by terminal, perhaps there is a problem between entering in the GUI and actually telling the machine.

Recently i've switched from ubuntu 8.04 to Lubuntu 10.04, since that time the powerbutton does not work anymore.I've tried to find out how powermanagement is implemented in ubuntu to be able to debug this problem. But most documentation about this topic seems dated.I've already tried a few thing, most important stuff I did is:
- tested the scripts in /etc/acpi/ and added a line to write something to a textfile when its called. But this file is not called when pressing the powerbutton.
- checked bios settings, seems alright (and these settings worked on 8.04 to).

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 ...

I have a new Thinkpad X1 Carbon (3rd) and i am very pleased with this machine so far.
Linux support is very good and i only have a few issues remaining.
I am running Debian Jessie and tried this with 2 kernels:
linux-3.16.7-ckt11-1
linux-4.0.4 (vanilla)
Main Problem at the time is really cannot get the power button to work.
thinkpad_acpi module is loaded.
I am not very familiar what possibilities are available to catch input devices. Some search in the internet brought me to the following commands. I tried evtest with no result
Code: Select allroot@x1carbon:~# evtest /dev/input/event3
Input driver version is 1.0.1
Input device ID: bus 0x19 vendor 0x0 product 0x1 version 0x0
Input device name: "Power Button"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 116 (KEY_POWER)
Properties:
Testing ... (interrupt to exit)
I tried acpi_listen also with no result
What else could i try? All other keys like lid event and all fn keys work flawlessly.
Just learned that the event needs about 1 second of pressing time to trigger

Whatever 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)

Today, I need to talk about some strange problem that faces me in my Linux Server, the power goes down and my server goes off, but when the power returns the server powered on and it works, but some services are not working properly like:
SSH, HTTP
When I try to login remotelt via ssh client like putty it ask me for username but, it hangs after I put my username and not asking me for the password. The second error is related to my web-server which redirect me to Apache default page and when I go for the terminal to make restart for httpd service, here is the output :
> service httpd restart
Stopping httpd: [ OK ]
Starting httpd: [Thu May 20 10:51:15 2010] [error] (EAI 3)Temporary failure in name resolution: Could not resolve host name admin.abakhiet.info -- ignoring!

This has got me stumped to the point where I have spent 5 days with little sleep trying to find what I did wrong. It should be simple yet it doesn't work. All I want to do is create a test /dev/fred device driver that will allow me to test my hardware, all I want to do is transmit some bytes out PSC5. It *should* be a simple matter:
1) Make sure PSC5's PADs are configured for Function 0, DS of 1
2) Make sure SCCR1 has PSC4, 5, and 6 ENABLED
3) Configure the PSC's registers for UART mode, transmit/receive enable, all that happy stuff.
4) Have an open, close, read, write, ioctl function
What happens is that everything hangs together just fine, when I open(/dev/fred) my open_iproc_psc6_uart2() gets called and everything gets configured -- I request memory, remap it, release memory as needed. When write(/dev/fred) is called, my driver's ech_write() is called and when read(/dev/fred) is called, my ech_read() driver function gets called -- great stuff, it should be *easy*.
The problem is, I get nothing out the transmit pin of the PSC. if I missed a configuration register some where? A clock I need to set? I'll have to sleep on this and maybe inpiration will come but this is such a simple thing I'm trying to do, it should work. In fact I compare my code against three examples on the Internet and it looks functionally the same. Code with debugging / un-needed stuff added to try to figure out whyt nothing comes out the serial transmit pin:
// ----------------------------------------------------------------------
// This is a device driver that creates /dev/fred and is used to send
// and receive serial data on PSC6. It's just a test driver, something

If, as root, I 'Leave' --> 'Logout', I get the KDE login screen.If, as user rob, I 'Leave' --> 'Logout', I get a black screen from which I must power off to recover, and I use the term very loosely. User rob is a member of the 'power' group.

I decided to upgrade my Asus Eee 900 from Lenny to Squeeze, to fix some issues that I was having. I did a fresh install using the beta1 netinstall cd image, and now my system is mostly working as I'd like it. Overall it seems quite good, and it even boots much faster than it did with Lenny.
I've encountered a problem, though. The suspend key doesn't work. I installed the package 'hibernate', and now the system can suspend via a command (which seems to work properly, although I haven't tested it extensively). I've noticed that the squeeze system doesn't have a command that my other Lenny systems do, 's2ram'. And I've noticed also that a package, uswsusp, which seems to be related to this kind of thing, can't be installed because it's not in the repositories: Package uswsusp is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'uswsusp' has no installation candidate

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.

I had unplugged my PC last night as sometimes there's storms at night this morning I plugged in PC and the power light is blinking and the PC wont come on at all tried different power cord, same result
PC is a AMD athlon64 3300+ 2.4ghz SiS graphics
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.

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?
