• standard keyboard doesn't work, but hotkeys do.

  - by alureonissue

  I posted earlier, but I've learned more about the problem since. (windows xp sp3) AVAST found alureon in kbdclass.sys and atapi.sys. I quarantined both files and restarted. keyboard and cdrom weren't working. I uninstalled them in device manager and updated the drivers. That fixed the cdrom but not the keyboard. Oddly, the keyboard hotkeys work (the row of special keys across the top for calculator, windows explorer, mail, browser) but the standard keys do not. I uninstalled and reinstalled SP3 to no avail. Any advice? not sure if I should have reposted this but I thought the hotkeys working might be an important point left out in the first post. Sorry if I'm doing this wrong ;/

• iPhoto fails to see my new iPhone 3Gs

  - by Alexey Kulikov

  Two weeks ago I have bought the new iPhone 3Gs. It synced like charm with iTunes and I was happy until a couple of days ago when I noticed that there was absolutely no way I could get any photos from the phone to my mac, as it doesn't even appear in the device list. Long story short — i have even tried resetting Leopard completely from scratch (and formatting the HD beforehand). Still no joy. Leopard Snow 10.6.1 absolutely clean install with all updates iPhone 3Gs 3.1.2 - syncs like charm with iTunes, but NOT iPhoto Mac Book Air Any help will be greatly appreciated! update: It works with my old iphone, why can't the 3Gs work?

• Errors reported by "powercfg -energy"

  - by Tim

  Running "powercfg -energy" under Windows 7 command line, I received a report with following three errors: System Availability Requests:Away Mode Request The program has made a request to enable Away Mode. Requesting Process \Device\HarddiskVolume2\Program Files\Windows Media Player\wmpnetwk.exe CPU Utilization:Processor utilization is high The average processor utilization during the trace was high. The system will consume less power when the average processor utilization is very low. Review processor utilization for individual processes to determine which applications and services contribute the most to total processor utilization. Average Utilization (%) 49.25 Platform Power Management Capabilities:PCI Express Active-State Power Management (ASPM) Disabled PCI Express Active-State Power Management (ASPM) has been disabled due to a known incompatibility with the hardware in this computer. I was wondering for the first error, what does "enable away mode" mean? for the second, what utilization percentage of CPU is reasonable? for the third, what is "PCI Express Active-State Power Management (ASPM)"? How I can correct the three errors? Thanks and regards!

• How to convert ext3 partition to use encrypted file system without loosing data?

  - by User1

  My embedded Linux device have 2 partitions: small root partition containing OS. big data partition which uses ext3 I want to encrypt the data partition by using encrypted file system. I don't want loose any data of the partition. Size of the root partition is too small to hold all data of the data partition. It is not possible to use any external data storage. Is there any tools that can convert filesystem of the data partition from ext3 to encrypted fs without copying all files to other place?

• ibm 8305-29u Sound comes from internal speaker instead of green port - Ubuntu 10.04 LTS

  - by TecBrat

  The title pretty much says it all. My experience w/ubuntu is VERY limited. I did find the system test feature and ran an audio test. It found my device as Intel 82801DB-ICH4. I wasn't getting anything. I tried a couple of things and don't really even remember what I tried, but I started getting audio (not just beeps) from the system's internal speaker. Any ideas? (I can't rule out a hardware problem. This box sat under my bed for a couple of years and it's first life was in an environment FULL of cement dust.)H

• zfs rename/move root filesystem into child

  - by Anton

  Similar question exists but the solution (using mv) is awful because in this case it works as "copy, then remove" rather than pure "move". So, I created a pool: zpool create tank /dev/loop0 and rsynced my data from another storage in there directly so that my data is now in /tank. zfs list NAME USED AVAIL REFER MOUNTPOINT tank 591G 2.10T 591G /tank Now I've realized that I need my data to be in a child filesystem, not in /tank filesystem directly. So how do I move or rename the existing root filesystem so that it becomes a child within the pool? Simple rename won't work: zfs rename tank tank/mydata cannot rename to 'tank/mydata': datasets must be within same pool (Btw, why does it complain the datasets are not within same pool when if fact I only have one pool?) I know there are solutions that involve copying all the data (mv, or sending the whole dataset to another device and back), but shouldn't there be a simple elegant way? Just noting that I do not care of snapshots at this stage (there are none yet to care of).

• please explain my fio results - is O_SYNC|O_DIRECT misbehaving on linux?

  - by Zoltan

  I'm going mad over figuring out what the problem could be with one of our storage boxes. With a simple fio script I'm testing random writes using bs=1M and direct=1. The SSD is a Samsung 840pro attached to an LSI HBA (3Gbit/s ports). This is the result I'm getting under FreeBSD 9.1: WRITE: io=13169MB, aggrb=224743KB/s, minb=224743KB/s, maxb=224743KB/s, mint=60002msec, maxt=60002msec This is regardless of sync being set to 0 or 1. On linux, this is the result with sync=0: WRITE: io=14828MB, aggrb=253060KB/s, minb=253060KB/s, maxb=253060KB/s, mint=60001msec, maxt=60001msec and with sync=1: WRITE: io=6360.0MB, aggrb=108542KB/s, minb=108542KB/s, maxb=108542KB/s, mint=60001msec, maxt=60001msec My understanding is that since I'm operating on the raw block device, O_SYNC should not make any difference - there's no filesystem, any barrier, anything between the writes and the drive itself. Especially with O_DIRECT|O_SYNC set. Any ideas? For reference, here's the fio script I'm testing with: [global] bs=1M ioengine=sync iodepth=4 size=16g direct=1 runtime=60 filename=/dev/sdh sync=1 [rand-write] rw=randwrite stonewall

• Good HDMI splitter solution

  - by Mehper C. Palavuzlar

  I have a full HD TV which has only 2 HDMI ports on it. Since I have more than 2 devices I connect to TV (e.g. laptop, game console, DVD player), it becomes uncomfortable to plug in and plug out HDMI cables every time I need to use the relevant device. I need a cheap solution to increase the number of my HDMI ports at least to 3. What type of splitter do you recommend? Does the quality of splitter matter, or do they all produce the same audio & video quality?

• Only one user at once through remote

  - by Lazlo

  Hi, This is probably an easy question for anyone used to servers, and I know I once managed to do it, but I don't remember how. I purchased a VPS and am able to connect correctly as Administrator, and can start, let's say, MyServer.exe. Problem is, if I connect as Administrator on another device, this process is still there, but I can't see it. What I want to do is limit the connection per user to 1, and disconnect others when one logs in. I know there was a simpler term, a simple way, but I truly don't remember. And since I'm not used to the vocabulary of servers, I couldn't find it in the S/F questions. Thanks in advance!

• Ubuntu not showing disk

  - by ojek

  I have a laptop which had broken windows 7 installed on it. I created a ubuntu live usb and tried installing ubuntu over that win7. After a few minutes, I got an error message, so I needed to restart the computer. Now the laptop says that there is no bootable device - reasonable message given that there was an error during linux installation. But: Bios can see my hard drive, When I start ubuntu in live mode, and try either sudo fdisk -l or gparted, it doesn't show any hard disk drives. I am 90% sure that hdd is broken, but it is wierd that bios can see it, and ubuntu doesn't. How can I be 100% sure about that hdd? Is there any additional way of detecting my hdd from ubuntu?

• Keep only "lock" a single app open in iOS?

  - by CT.

  Is there anyway to "lock" open a single app in iOS? My use case for this is simple. There are many apps and games designed for children. While these applications are appropriate for children, many other applications installed on an iPad are not. But even more so than protecting them from inappropriate content, I would just like to prevent them from leaving the application. They accidentally hit the home button or multi-touch gesture out of the application. I know you can turn gestures off. Developers also have links to their website or other related applications. Kids are constantly exiting the application and then bringing the device to me asking "Can you get me back into the game?" every couple minutes. How can I hand a child an iPad with "Angry Birds" running and make sure only "Angry Birds" runs? Cydia or jailbreak tweaks welcome. Thanks.

• Is it common to have portable hard drive not recognize?

  - by lamwaiman1988

  I have a bad hard drive which could not be recognized by windows. If windows can recognize it, it could just be pure luck. There are better chance of it being recognize by plugging it at the usb back of the machine, rather than the front one. More interestingly, I have a usb cable which fork itself at one side ( i.e it has 2 heads at one side ). I can plug both heads to the machine and connect the portable hard drive on the other end of the usb cable? Can I get more voltage by doing this? I am guessing the front usb port doesn't have enough power. I am wondering if I buy a new portable usb hard drive, would it have easy read by plugging at the front usb port? I am not sure if I screw up the jumper connecting the front usb ports, but it is okay for other device such as usb stick and mouse.

• How to configure LAN IP Filter on Huawei E586 UMTS Modem

  - by Mose

  I need to prevent clients of an Huawei E586 UMTS to WiFi modem from downloading much data from specific servers eg. Windows update or OSX update. On the config page of the device there's an "LAN IP Filter" which seems pretty good but I can't figure out the right settings. The mask looks like this: The help pages states the following: My problem with this is, I want some wildcard for the local ip and port. In my opinion the help page can not be correct by "lan port: enter 80" because the source port is normally dynamic. I tried to set it up like stated there but as expected it doesn't work. As wildcards I tried * and "ALL" but nothing worked as it prevents me from saving settings with an "wrong value" error. Any suggestions? Thanks in advance!

• Laptop wakes from sleep, once, due to audio controller (Windows 7)

  - by stijn

  The laptop is a recent Dell XPS 15z and the problem is as follows (reproducible about 90% of tries): put laptop to sleep using either Start-Sleep or closing the lid laptop goes to sleep after about 5 seconds, but instantly wakes again showing a black screen (touching the keyboard or moving the mouse shows the login screen one normally gets after wake) login again, put laptop to sleep latop stays in sleep mode output of powercfg -lastwake after the first instant wake shows the audio controller is responsible. Why would that be, why only the first try, and how to fix this?

• How to connect my Android to my Laptop wirelessly , to stream data between the two?

  - by Deepun

  I want to stream data from my Laptop PC to my Android phone using TCP or UDP by creating sockets in both the phone and the laptop, but it has to be done wirelessly. How do I connect them to stream the data ? I thought creating an ad-hoc wireless network from my laptop and connecting to it using my Android would work. But my Android is not detecting the ad-hoc network. Is there any other way how I can connect the two ? I downloaded this software called 'connectify' and created a wifi hotspot on my laptop, and successfully connected the two. But will I be able to stream data to my device using this connection ? Can simple direct Bluetooth connection help me in creating sockets in both phone and laptop and stream the data ?

• CentOS Failover Cluster - SIOCADDRT: No such process (when adding a loopback)

  - by Steve Rolfe

  I'm trying to configure two web servers for a load balancing server. The load balancing aspect works fine (it sees both server, kills 'em if it needs to, and seems to direct traffic fine). The only issue is with the servers looping: /etc/sysconfig/network-scripts/ifcfg-lo:0 DEVICE=lo:0 IPADDR=<Virtual IP> NETMASK=255.255.255.255 ONBOOT=yes NAME=loopback Everytime I try a "service network restart" I get a SIOCADDRT: No such process when loading the loopback interface. Anyone have an idea what's causing this?

• Is it possible to install Canon EOS T3 Camera Drivers on Windows 7 Embedded

  - by Ryan Johnson

  I have a computer running Windows 7 Embedded. It's an embedded system that will be used in a industrial setting. It needs to be connected to a Canon EOS camera and download pictures from the camera. Other versions of windows come with the Canon drivers so Canon does not provide them as a download on their website. In the past, I had a similar issue with the "N" version of Microsoft Windows Starter and had to download the "Microsoft Media Feature Pack" which then installed the drivers. I attempted to install that on this device, but understandably it complains that its not applicable for this version of windows. So, is there there a feature pack or some other sort of download available that will install the camera drivers? Alternatively, is there some place to get the drivers and manually install them. Thanks in Advance, Ryan

• Ubuntu server very slow out of the blue sky (Rails, passenger, nginx)

  - by snitko

  I run Ubuntu server 8.04 on Linode with multiple Rails apps under Passenger + nginx. Today I've noticed it takes quite a lot of time to load a page (5-10 secs). And it's not only websites, ssh seems to be affected too. Having no clue why this may be happening, I started to check different things. I checked how the log files are rotated, I checked if there's enough free disk space and memory. I also checked IO rate, here's the output: $ iostat avg-cpu: %user %nice %system %iowait %steal %idle 0.17 0.00 0.02 0.57 0.16 99.07 Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn xvda 2.25 39.50 16.08 147042 59856 xvdb 0.00 0.05 0.00 192 0 xvdc 2.20 25.93 24.93 96530 92808 xvdd 0.01 0.12 0.00 434 16 xvde 0.04 0.23 0.35 858 1304 xvdf 0.37 0.31 4.12 1162 15352 Rebooting didn't help either. Any ideas where should I be looking?

• Windows 8 will only recognize the Blu Ray ROM, if the install disk is present at boot time

  - by aceinthehole

  If I have the install disk in the blu ray ROM drive at boot time and subsequently remove the disk and replace it with blu ray media everything functions as I'd expect. However, if I have no media present, or another disk in the drive at boot time, then windows 8 does not seem to recognize that the blu ray player is even present in the computer. It is not present in the 'my computer' screen, device manager does not show the player, and scanning for new hardware yields nothing. It seems that the driver is installed and working as expect, what is it about having the windows 8 install disk in the drive or not that would cause this kind of behavior?

• Snap Server 18000 connection help!

  - by sicko666

  I wonder if anyone here can help me. I have a home server setup made up of old secondhand computers, 2 servers running Windows Server 2003, 1 workstation running Windows 7, a 16 port switch & an adsl ethernet modem. All these connect and talk to each other fine but then I got a "Snap Server 18000" and a "Snap disk 30sa" sata array. When I turn the Snap on, it boots past the BIOS, runs a kernel, then displays: This device cannot be managed via the video/kbd/mouse interface. The video is now disabled. You may access the management functions from your web browser. Only, none of the other PCs detect it, so no browser can find it! I have checked all cables, and all LEDs indicate there's a connection. I have installed the windows "iscsi" and the adaptec "Snap Server Manager" on all PCs but still it's not detected. I don't know what else to do, please advise!

• How can I chainload a USB drive from GRUB2?

  - by magic.plane

  I'm using GNU GRUB version 1.99-12ubuntu5, booted over the network using PXE. I used grub-mknetdir to generate the GRUB image and directory tree, which I'm serving on a TFTP server using Tftpd32 in Windows. I've put the latest version of Clonezilla on my USB drive using Tuxboot. Right now, in GRUB's CLI, using ls lists only the (pxe) device, even if the USB drive is plugged in before the computer is on. Is there any way I can chainload Clonezilla on my USB from GRUB, which is booted over the network?

• How can I get 32-bit Direct3D working on my 64-bit Windows 7 system?

  I recently upgraded a Dell Inspiron 6400 to Windows 7 Ultimate 64-bit. I have a 32-bit 3D application that refuses to run, giving an error of "Failed to initialise [sic] Direct3D device".

• Windows 2003 SBS: no more CAL sold

  - by Gregory MOUSSAT

  I just discovered a hidden unmanaged server into a remote location. This is a Windows 2003 SBS with 5 CAL per device. There is currently 12 computers connected. So I want to buy more CALs. But SBS 2003 CALs are not sold anymore. Neither SBS 2008 CALs, which can be downgraded to 2003. And 2011 CALs can't be downgraded. So no legal solution if we want to stay with 2003. Sort of programmatic obsolescence. We can upgrade the server to 2011. But I'd like to let him as is (I don't "repair" working servers, and this often lead to bigger problems, especially on those non managed servers). Anyone see another solution ?
