I have a home-fileserver with 6 desktop harddisks in a md-raid.
The server isn't accessed a lot, so I think it would be good for the harddrives to go in standby-mode after some idle time (e.g. with the hdparm -S or hd-idle command).
Is this safe when using mdadm or could this cause errors/degraded harddisks?
to do all the time fsck at boot, how to chagne this value to 4 please?

On "suspend," the wireless card appears to close connections correctly. Then, >15 minutes later, the laptop's wifi LED lights up and the laptop generates heat.
The computer should be on standby, but instead it's waking itself up and running down the battery.
Are there any programs that might be failing to suspend for sleep? Are there any settings to prevent the wifi card from waking the computer?
I only noticed this because the laptop was getting hot and the battery was wearing down.
Visibly the conventional Cdrom of Debian Testing Install cannot recognize 2 terabytes harddisks. Well this is surprising since it is quite common nowadays to use 2TB
Business card cdrom can see them and install it
For several days I have tried to create a new raid5 array, after accidently blowing up the old one.But it seems that the raid data was burned into the harddisks ineradicably. I keep seeing the raid data that was used for the old array. I have tried everything to remove the old data, even installed a new distro but still I see the old data.My last hope is to erase the disks with a lowlevel tool to make a clean start.

View 1 Replies View RelatedCould any RAID gurus kindly assist me on the following RAID-5 issue?I have an mdadm-created RAID5 array consisting of 4 discs. One of the discs was dropping out, so I decided to replace it. Somehow, this went terribly wrong and I succeeded in marking two of the drives as faulty, and the re-adding them as spare.
Now the array is (logically) no longer able to start:
mdadm: Not enough devices to start the array.Degraded and can't create RAID ,auto stop RAID [md1]
I was able to examine the disks though:

Ever since I upgraded to Ubuntu 10.10, my laptop won't go into standby. The screen goes black, but then refreshes with the login screen.
View 1 Replies View RelatedThis happens on Ubuntu 9.04, 10.04 and Mint 8 "Helena".
The computer: Aser Aspire One D150 with 2gb of RAM, Ubuntu/Mint (depends on the day) booting from a SDHC card.
Problem: When I unplug the computer to move it or plug it in it will go immediately into standby. I go to wake it up, it runs for a few seconds and goes back into standby. After that, it is fine until I unplug it or plug it in again.
This is probably really a quick fix but I cannot seem to find it. When I close my laptop lid it brings me to the standby screen which then asks me to put my password in, when i log in I managed to make it not ask me for a password but on the standby screen it still does.
It's just annoying me a little and wouldnt mind just being able to open my laptop and go. also same kinda problem with installing software, always asking for passwords but I guess i can live with that one.
I have a Toshiba Satellite laptop, dual-boot with Win7 and Ubuntu 10.10. Everything works as it should in Ubuntu, except when I resume from standby the computer goes into a "kernel panic," the screen freezes and caps lock light blinks.
I travel with my laptop and use standby all the time being a student, so I've been forced to use Windows 7 because it's far more reliable (isn't that funny >_<) when I resume from standby..
After literally searching for DAYS, no solutions have worked for me, and apparently this is a pretty big issue. I would love to get Ubuntu running full-time on my laptop. Also, my display drivers aren't officially supported by Ubuntu, but I'm not sure if that has anything to do with it.

I have Xubuntu with XFCE Desktop installed. I have disabled all screensaver and power save options, but Monitor still goes into black standby mode. Howto prevent this?

I just was confronted with one problem. At my Home PC I was working normally using FileZilla and drag and dropped something from FTP to local machine, then suddently my PC locked and the Screensaver appeard. I mean this Matrix Saver is nice but not when you want to work
Then first I thought it simply locked the workspace and tried to login, but it did not accept any key input, then it just went to standby after some sec..
I really wonder how that can happen, I had deactivated automatic standby in the energy settings, because I don't use it.
To activate multitouch on my N150 netbook I have to execute the following script:
Code:
synclient VertTwoFingerScroll=1
synclient HorizTwoFingerScroll=1

I don't know how to stop this monitor standby thing. When I'm not using the computer, the screensaver will start after a few minutes, what I want. But after a few minutes then, it'll go black. How can I stop this from happening?

Am currently using 8.10 (xubuntu). The machine's "issue" (I've searched for a reference, but the one I found was a forum thread with no answers) is that when the display is set to go to sleep after 8 minutes of idleness in the power manager, it projects a black screen instead.
I'm not sure what different 'power saving modes' a display/OS usually has, but in Windows, when set to 'go to sleep' the screen goes into standby, i.e something like 'no signal', and from what I've read a lot more power is saved in that mode than by simply showing a black screen.
It was the same when I was running 8.04 with a different graphics card, if that matters. Haven't been able to try a different display. Screensaver and timing and resume normal video out works ok.
I'm using Karmic since November and standby/sleep has always worked fine. Some weeks ago, it stopped working fine.
After a reboot, I can put the system in standby only once. If I try standby after that, the system seems to do a normal standby, but it resumes at the moment the fans would normally stop working.
I tried different things like the s2ram program, pmi action sleep, etc. I went to the BIOS and tried a number of things, one was succesfull: disable USB. When USB is disabled I can go into standby every time. When I enable USB again (even with no devices connected), standby only works once again.
So, how can I disable USB at the moment I go into standby?
I installed ubuntu 10.04 32bit on my t60 (T2400(1.83GHz), 1GB RAM, 60GB 5400rpm HD, 14.1in 1400x1050 LCD, 64MB ATI Radeon X1300, CDRW/DVD, Intel 802.11abg wireless, Bluetooth/Modem, 1Gb Ethernet, UltraNav, Secure chip, 6c Li-Ion batt).
If i set the computer to standby, i loose mice cursor. It is there (i see it goes to dock or menu), but it is invisible.
Is there any way to make it so I can let my laptop go into standby that is connected to my printer and make it so that I can still see the printer from my other systems. Then if I print something it brings the networked printer/laptop out of standby and prints my job. I just ran a test and when my system went into standby the printer went "offline" and I couldn't print from it. I don't want to be forced to leave my computer fully on 24/7 to have a networked printer.

View 2 Replies View RelatedI am using WICD as my wireless network manager and it works connecting to a network for the first time. But when I resume my laptop from hibernate or standby, WICD will not reconnect to the network and gets stuck on obtaining an IP address. And if I try to change networks without hibernating I get the same problem. Also, I notice that the network name is stagnant. I connect to multiple wifi networks a day because of school. When I leave my "home" network and connect to my "school" network WICD still says "Homebtaining IP address" even thought it should say "schoolbtaining IP address." My thoughts are that it isn't releasing the network properly and when its trying to connect it can't because it still thinks it's connected. The only solution I have found is to restart my laptop every time I want to connect to a new network, or shut down every time I am done using my laptop, which is a major inconvenience.
Here is what I am using:
HP tx2000
Broadcom BCM4322
Ubuntu 10.04
WICD 1.7.0
I have been working on this problem for a few month. By messing with windows registry and local security policies I was able to remotely shut down windows from Linux by issuing:
Code:
net rpc SHUTDOWN -C "comments" -f -I xxx.xxx.xxx.xxx -U username%password
But now I am wondering how to force windows into sleep or suspend remotely from Linux.
It seems that there is no "net rpc SUSPEND" or "net rpc STANDBY" option available.
how to perform such remote operation?
i am running 9.10 on a compaq 2209cl laptop. has been working great with no issues till i updated the other day. when i come out of standby (opening laptop lid, or hit the power button to wake up) my network connection does not start, and there is no wireless networks displayed. a reboot usually takes care of this prob until it goes into standby again. just wanna know if there is a way i can solve this myself or if i gotta wait for a patch? it aint too bad but is sure is annoying when i get on and off this thing all the time.
View 9 Replies View RelatedI just bought a Logitech V470 bluetooth mouse. It's no problem to let it work under Koala 9.10 (gnome), but after shutdown/standby/sleep, it doesn't work anymore. With my USB mouse, I have to click the bluetooth icon and select 'switch off bluetooth'. After that, I click 'switch on bluetooth' and bluetooth works again. I thought switching on and off bluetooth with the applet is the same as 'sudo /etc/init.d/bluetooth start/stop', but it isn't! The previous command greyes out/in the bluetooth icon, but it doesn't resume my bluetooth. If 'sudo /etc/init.d/bluetooth restart' would work, I would be able to add this line into /etc/pm/sleep.d, so it's automatically loaded on resume.
