• Applications randomly alt-tab? (especially full screen games)

  - by Henry Scotts

  I'm not sure when this began, how it happens, or why it happens, but it is quite bothersome and apparently random. Just randomly throughout the day my computer will just go to the desktop. I could be in a full screen game and it will just immediately alt tab and present the desktop. Or I could be watching a movie and this happens. Sometimes it happens once every three hours and other times (just today actually) it did it twice in the span of 30 seconds. I am positive I am not pressing a hotkey because I launched a game, sat idle, and noticed it alt tab while cleaning up around my room after about 20 minutes. Sometimes it goes days without this happening. Specs: Windows 7 Ultimate 64 Bit, 10 gigs of RAM, GeForce GTX 260, Intel Xeon CPU. I also have basically nothing running when it happens other than the game and FireFox. My FireFox add-ons: Adblock Plus, Download Statusbar, Firebug, FirePHP, lazarus form recovery, tree-style-tabs, yslow. I doubt FireFox is causing the issue but I figured I'd include it anyway because it is the only application I have running when it happens. As for user processes I have running: VCDDaemon (context menu for virtual clone drive), razerhid (mouse), OSD, taskhost, dmw (desktop window manager), anyfullscreengame, audiorepeater, netsession_win, explorer, razerofa, tsvncache, firefox, plugin-container, and EKIJ5000MUI (printer). Whew. Okay. That was a lot of information. If someone could diagnose this I would be most grateful for this has been around with me for years.. Thanks for reading! PS: I doubt it's a virus because I never download illegal software and pretty much only browse Reddit and Stackexchange and play games. If it was a virus it would be a pretty lame one.. Hah..

• How to set up RAID-0 first time on new PC?

  - by jasondavis

  I have built basic PC's in the past but have never used a RAID array at all. SO now I am buying parts to build my new PC, it will be an intel i7 processor. My motherboard will have RAID support which I will use instead of an aftermarket raid controller for now. Also I plan to use 2 SSD drives in RAID-0 for my windows 7 OS. (Please note that I am aware of the issues with doing this, including lack of TRIM support when using RAID with SSD drives. I am OK with it not working as I can just re[place the drives in a year or so or wheneer they become more sluggish). SO here is my question part. If I assemble the motherboard, PSU, processor, RAM, vidm card, etc and then go to turn the PC on, it will have the 2 SSD drives hooked up. so I assume I will then soon the BIOS screen before I install windows? How to I go about making the 2 drives work in RAID-0 at this point? I do the raid part before installing my OS right? Please help with the steps involved from assembling the parts of the PC and then turning it on, to the part of getting the RAID-0 set up between the 2 drives and then installing my windows 7 OS from a Optical drive? Please help, all advice, instructions, tips appreciated as long as on topic. I do not need to be told that this is a bad idea as far as if 1 drive fails I losse it all, I plan on having a disk IMAGE to be able to restore my OS and software to a new set of drives at anytime needed in the event of drive failure. Same goes for lack of TRIM support. Thanks for reading and help =)

• Very Slow DSL (ethernet) speed

  - by Abhijit

  I 'was' on opensuse 12.2 when my dsl speed was normal. Yesterday I switched from opensuse to ubuntu 12.04 and speed decreased. It came to range of 7-10-13-20-25-kbps. Then I switch to linux mint, and then to fedora. Still slow speed. When I was in ubuntu I disabled ipv6 but still no luck. Now I am in fedora but this time with DIFFERENT ISP. And still I am getting very slow sped. So my guess is this is nothing to do with os. What can be wrong? Is this problem of NIC? Does NIC speed decreases over time? Does NIC life ends over time as with keyboard or mouse? Help please All the os I used are 64 bit and my laptop is Compaq Presario A965Tu Intel Centrino DUal Core. Interesting thing to notice is I get normal speed while downloading torrent inside torrent client softwares. This slow speed issue applied to download from any web browser or installing software using terminal.

• Linux Mint Constantly freezing on Dell XPS L502X

  - by Josh

  I recently partitioned my hard drive to dual boot the existing Windows 7 with Linux Mint because I am tired of using Windows, especially the lack of terminal. I want to eventually remove Windows 7 and just run it from a VM within Linux Mint, but I want to make sure that I like the Mint before going all in. I ran Linux Mint on a VM inside Windows for a while, enjoyed it, and never had any issues with it. Since installing on my hard drive it has started freezing every 5-10 minutes, and the only way to get it back is to either power down, or close the lid and reopen once it sleeps. I've also tried running Ubuntu on dual boot in the past, and while it never froze, the battery life was terrible, and the fan was constantly running. I'm experiencing the same battery/fan problem with Mint, which doesn't make sense to me, as Linux should be lighter on the CPU than windows. If I had to guess I'd say it's probably a driver thing, with my video card or fan or something. My battery life in Windows is ~2 hours and its about 40 minutes in Linux. At this point, that is even if my laptop doesn't freeze before then. On a less important note, I also have an intel Centrino 6150 WiMax card that I'd like to be able to use, but that won't register on the Linux system either. I have tried downloading drivers for both of these, but neither have solved my problems. I'm definitely getting frustrated and am getting close to giving up on Linux even though I dread working on a Windows machine.

• "Can't find root filesystem / error mounting /dev/root" when booting to new kernel

  - by salparadise

  I am trying to upgrade my kernel from 2.6.18-274 to 2.6.39 for some wireless card drivers. When I boot into the new kernel I get the "Can't find root filesystem / error mounting /dev/root" googling led me to this page http://fedoraproject.org/wiki/Common_kernel_problems#Can.27t_find_root_filesystem_.2F_error_mounting_.2Fdev.2Froot From what I am reading seems to be an issue with a driver for my SATA controller or HD, but I can't find what option I need to add to the kernel. Doing a diff from the old initrd to the new one gives me the following: root-> diff /tmp/kafter /tmp/kbefore 6a7,8 > lib/dm-message.ko > lib/dm-region_hash.ko 8a11 > lib/dm-raid45.ko 13d15 < lib/dm-region-hash.ko 16a19 > lib/dm-mem-cache.ko Do I need any of those? not sure if I would need dm-raid45.ko as I am not running a raid. I have the same SATA and IDE options configured for both kernels so not sure what else to look for, any help is appreciated.

• Varnish, Nginx, Apache, APC, Meteor, Cpanel & Wordpress On A Single Server, Any Good?

  - by Aahan

  Yes, I have read many close questions, but I needed a specific answer and hence this question. First, these are my new server specifications: Linux Server (CentOS), Intel Xeon 3470 Quad Core (2.93GHz x 4) processor, 4 GB DDR3 Memory, 1TB Hard Disk Space, 10 TB Bandwidth and 9 Dedicated IPs. AIM: To speed up my wordpress blog + Increase server's capacity to handle heavy load PLAN: This is how I am planning to setup my server - - VARNISH (in the front, to cache server responses) NGINX (to effectively handle static content & overcome the C10k problem) APACHE (behind Nginx, to effectively deliver dynamic content) APC (PHP page, database & object caching) CPANEL (which requires Apache, and I require it) WORDPRESS W3 TOTAL CACHE (caching plugin for Wordpress). So , will the setup work? Have anyone tried it? Please shower your thoughts and knowledge. NOTE: I can't do without Apache because I am used to that .htaccess & Cpanel stuff. So, it's not any option. All others are options. Please try to help. I hope I am clear in what I wanted to ask.

• Codecs, Premiere Pro & Quicktime: Import or Play Error

  - by Nchpmn

  Original Question I've been using a FS-H200 (not the Pro variant) recorder with a JVC ProHD camera. I have been shooting with the DTE FORMAT to Quicktime (.mov). I copied the files to an external hard drive and am now trying to edit. The files will play back in VLC, as they would be expected to. However they will not import into Adobe Premiere CS5.5, instead giving an error: Unsupported format or damaged file. Quicktime gives the following error when attempting to play the files: Error -2002: a bad public movie atom was found in the movie (Filename) To try and fix this, I have installed the following codec packs: K-Lite Codec Pack 64-bit Full (version 5.9, latest) K-Lite Codec Pack 32-bit Full (version 8.4, latest) MainConcept Codec Suite (Broadcast) v5.1 for Adobe CS5 Reinstalled Quicktime with new download from Apple The same errors and problems still exist. From this I can assume that there is an issue with Quicktime and that is what Premiere is using as an encoder/decoder for the codec. Is there any way to fix this? From looking at the "Codec Information" from VLC: Stream 0 Type: Video Codec: MPEG-1/2 (mpgv) Language: English Resolution: 1280 x 720 Frame Rate: 25 Stream 1 Type: Audio Codec: PCM S16 BE (twos) Language: English Channels: Stereo Sample Rate: 48000 Hz Bits per sample: 16 Other computer specs: Windows 7 Professional 64-bit (SP1) Gigabyte Z68X-UD3-B3 Intel i7-2600K 16GB DDR3 2TB WD 7200RPM SATA 6Gb/s LaCie d2 Quadra 2TB v3 7200RPM (External HDD) NVIDIA GeForce GTX 560 Ti Golden Sample Updates 2012-03-11 @ 2050 AEDT MPEG Steamclip doesn't recognise, play or convert the footage.

• HP Proliant DL380 G4 - Can this server still perform in 2011?

  - by BSchriver

  Can the HP Proliant DL380 G4 series server still perform at high a quality in the 2011 IT world? This may sound like a weird question but we are a very small company whose primary business is NOT IT related. So my IT dollars have to stretch a long way. I am in need of a good web and database server. The load and demand for a while will be fairly low so I am not looking nor do I have the money to buy a brand new HP Dl380 G7 series box for $6K. While searching around today I found a company in ATL that buys servers off business leases and then stripes them down to parts. They clean, check and test each part and then custom "rebuild" the server based on whatever specs you request. The interesting thing is they also provide a 3-year warranty on all their servers they sell. I am contemplating buying two of the following: HP Proliant DL380 G4 Dual (2) Intel Xeon 3.6 GHz 800Mhz 1MB Cache processors 8GB PC3200R ECC Memory 6 x 73GB U320 15K rpm SCSI drives Smart Array 6i Card Dual Power Supplies Plus the usual cdrom, dual nic, etc... All this for $750 each or $1500 for two pretty nicely equipped servers. The price then jumps up on the next model up which is the G5 series. It goes from $750 to like $2000 for a comparable server. I just do not have $4000 to buy two servers right now. So back to my original question, if I load Windows 2008 R2 Server and IIS 7 on one of the machines and Windows 2008 R2 server and MS SQL 2008 R2 Server on another machine, what kind of performance might I expect to see from these machines? The facts is this series is now 3 versions behind the G7's and this series of server was built when Windows 200 Server was the dominant OS and Windows 2003 Server was just coming out. If you are running Windows 2008 R2 Server on a G4 with similar or less specs I would love to hear what your performance is like.

• Scaling databases with cheap SSD hard drives

  - by Dennis Kashkin

  Hey guys! I hope that many of you are working with high traffic database-driven websites, and chances are that your main scalability issues are in the database. I noticed a couple of things lately: Most large databases require a team of DBAs in order to scale. They constantly struggle with limitations of hard drives and end up with very expensive solutions (SANs or large RAIDs, frequent maintenance windows for defragging and repartitioning, etc.) The actual annual cost of maintaining such databases is in $100K-$1M range which is too steep for me :) Finally, we got several companies like Intel, Samsung, FusionIO, etc. that just started selling extremely fast yet affordable SSD hard drives based on SLC Flash technology. These drives are 100 times faster in random read/writes than the best spinning hard drives on the market (up to 50,000 random writes per second). Their seek time is pretty much zero, so the cost of random I/O is the same as sequential I/O, which is awesome for databases. These SSD drives cost around $10-$20 per gigabyte, and they are relatively small (64GB). So, there seems to be an opportunity to avoid the HUGE costs of scaling databases the traditional way by simply building a big enough RAID 5 array of SSD drives (which would cost only a few thousand dollars). Then we don't care if the database file is fragmented, and we can afford 100 times more disk writes per second without having to spread the database across 100 spindles. . Is anybody else interested in this? I've been testing a few SSD drives and can share my results. If anybody on this site has already solved their I/O bottleneck with SSDs, I would love to hear your war stories! PS. I know that there are plenty of expensive solutions out there that help with scalability, for example the time proven RAM-based SANs. I want to be clear that even $50K is too expensive for my project. I have to find a solution that costs no more than $10K and does not take much time to implement.

• Linux wireless disconnect every 20 minutes

  - by james

  My laptop uses CentOS 6.3 with kernel 2.6.32-279.el6.x86_64. My wireless adaptor is Intel Corporation Centrino Wireless-N 1000. My wireless connection always get off after about 20 minutes. The network applet shows the connection is still on with good signal strength, but I just cannot load any web pages even the configuration page of the wireless router. The problem will continue until I disable and reconnect the wireless. Other devices like my cell phone uses the same wireless network without the problem. Even yesterday I'm using the same laptop with Fedora 17 without this problem. I also searched the internet and someone said running services NetworkManager and network simultaneously may be a problem. But I cannot stop any one of them because: if I stop network and start NetworkManager, the network service will start automatically; if I stop NetworkManager and run network, it says "Device does not seem to be present, delaying initialization." when trying to bringing on the wireless. What shall I do to get rid of the problem? Thank you very much!

• Connecting a laptop to a TV via HDMI

  - by Madmartigan

  I just bought a new Dell XPS17 laptop (Win7) that only has HDMI output. My last 2 laptops had VGA, which I used to connect to my Sony Bravia 32" TV with no issues, but with the HDMI it's been quite a headache. Drivers for display adapters have been updated to the latest versions: Intel(R) HD Graphics Family NVIDIA GeForce GT 550M I went to a store and plugged in to 4 different TVs from different manufacturers. A sales rep and I spent about 30 minutes being baffled by the results (which are the same as my current TV): Extreme buggy behavior in the Nvidia and Windows display/resolution control panel Can not extend or duplicate displays, can only select one Third and fourth output devices "randomly" detected by the Windows control panel Could not get the screen to fit the output (edges cut off on all sides by about a half inch) Resolution and colors less than perfect. Artifacts around text. Display "randomly" cuts out Defaults to TV output only when plugged in Can not change resolution on either device when connected No audio from the TV Plugged in to 3 monitors from different manufacturers: Defaults to duplicated displays when plugged in Everything works perfectly So far, four people have gone through all the settings in the latop with no luck. I had similar, but not exactly matching results with a different laptop. I'm using the Sony Bravia currently at home, but in order to get it to work I have to turn on the laptop, wait until the display shows up on it, close the lid, then cycle through each output channel on the TV until I come back around to the HDMI port again, but still I have the symptoms described above. However: Once in a while, it just works. Sometimes, seemingly randomly, the output fits the screen perfectly. Sometimes the audio comes through the speakers too, but not always. Usually my screen saver "Mystify" will come up with a message that it cannot be displayed due to a limitation of the video card, but then sometimes it works fine. These 3 things seem to be independent of each other and don't always happen together. So, is there any way to get the laptop to output correctly to a TV, or is it just not meant to be?

• Hibernate between OS X and Bootcamp Win 7

  - by Willem

  Wouldn't it be great if someone wrote a guide or an app which allowed you to switch instantly between OS X and Windows using Hibernate in both OS:s? Windows 7 already has an option "Hibernate" which allows you to boot back to your OS X partition, but OS X does not exactly offer the same. However, there are possibilities here. It seems that the recent Mac's have 3 different kinds of sleeping mode: Sleep: Low power consumption, RAM still active. Legacy Safe Sleep: No power consumption(?), writes RAM to disk and shuts down (is this the same as Hibernate?) Safe Sleep: Writes RAM to disk and enters sleep mode. If battery level drops too low it goes into Hibernate (is this Hibernate the same as #2 in this list? This is the Hibernate I will be referring to int he rest of this post) It seems that I am unable to force my MacBook Pro (Late 2011) OS X 10.7.3 into a true hibernate using either command line or apps that are supposed to do this. I believe the Mac should show that white loading bar whilst waking up if it was truly put into hibernate (which it does not). But I can get this white bar to show by letting my battery level drop to 0% so there is obviously a system function for it (obviously, duh! :). When Win 7 goes into hibernate it shuts down completely and you can then boot into OS X on startup. On OS X however, hibernate forces you to wake up into OS X. Can you hack this so that you're allowed to select boot partition after OS X hibernates? Would it be possible to use the true hibernate system functionalities of Win 7 and OS X to create a kind of instant switching between the two? Imagine this on a quick SATA-3 SSD like my 180GB Intel 520. Thanks / Willem

• Power issues Foxconn Barebones kit

  - by alpha1

  I have a Foxconn R20D2 bought about a year and a half ago. It ran fine for a while and then around last summer it started having power issues. I chalked it up to changes in electric current due to the overwhelmed grid when people turn on their AC units, but this problem has stayed for all year, shutting off randomly, shutting off when i turn on a vacuum and similar problems. Now that its summer again, the box basically sits there all day cycling itself, and now has gotten to the point it tried to boot and after 3 seconds, fails, shuts off and tried again. I know its power related, it runs opensuse linux and there are never any shutdown logs or anything of that sort. As the weather got hotter i noticed it happening more and more, and it most often happened in the morning, i presume as people woke up and turn on the AC. The power supply is a Chennel well technology co LTD model DSL-150. 150W max output. Its an intel atom dual core, with 2 sata drives, no CD/floppy etc, recently upgrades from 2 to 4gb of ram. It runs at 104 degrees Fahrenheit all the time almost. Any way i can test the power supply or anything else to try to fix it? Im a software guy, not hardware so im at a complete loss here, thanks for all assistance you can provide! EDIT: The switch on the back that says 230 or 115 is set to 230. If im in the USA, could that be causing the problems?

• Ignore non-unicode programs language when installing software

  - by mitya

  This is something that is driving me nuts for a while and I haven't been able to find a solution for this problem anywhere. I am running Windows 7 and my "Language for non-Unicode programs" setting is set to Russian. I need for some non-unicode software that has a Russian UI. However, for most of my software I prefer to use the English UI. A lot of software out there is multilingual and is too smart for my liking. When installing, it switches the UI to Russian and the software UI stays in Russian after the installation without an option to change that, besides setting the "non-unicode language" to English. It switches back to Russian once I revert the setting and reboot. Most of the time it is driver software, i.e: Intel, HP, etc. How can force the installation to run English and stay that way after install, ignoring the "Language for non-Unicode programs" setting? Now, I understand this might be specific to the installer: MSI, Install Shield, etc. But any solution will be good, even if I have to apply it for every software installation. Thanks in advance for any helpful information!

• Important hardware components to avoid bottlenecks/improve speed on a laptop?

  - by joelhaus

  Looking for a powerful general use (including web development) laptop running Windows. Price points seem to be all over the place. Many less powerful machines are priced much higher than machines with better specs. How does one navigate this market? Are there any unpublished/under-publicized specs/bottlenecks you look for? Understanding that hardware improves over time, is there an efficient ratio that can be used (or something similar, like Windows Experience Index?) which will indicate how powerful a system is? Thanks in advance! P.S. Here is an example from a laptop released on September 17, 2010. Can anyone pick apart these specs? Is there missing information you would be looking for? OS: Win 7 Display: 16.4" LED backlit Processor: Intel Core i7-740QM, 6MB L3 Cache RAM: 6GB DDR3 1333MHz (8GB max.)

• keyboard intermittently stops working, even after reinstalling windows 7; possibly a Chrome issue?

  - by neverskipbreakfast

  My keyboard intermittently stops working. Sometimes a couple of keys will work, but usually none. Sometimes if I mash a couple of the ctrl+alt+windows type keys randomly for a bit, the keyboard will let me type one more letter before stopping again. Sometimes the keys will open a program menu, but usually not. I have even completely wiped my machine and reinstalled windows 7; the problem continues. Specs: Intel iMac (early 2006, 2.0GHz, 2MB RAM, 240GB HD) running ONLY Windows 7 Professional, 32-bit (NOT through boot camp) and using a USB keyboard (Saitek Eclipse II.) *Unplugging & reconnecting keyboard does NOT fix it. *Connecting a different keyboard does NOT fix it. That one won't work, either. *Drivers are up-to-date. Removing and reinstalling drivers does NOT fix it. *Restarting the computer does NOT fix it. In fact, when the Windows logon screen appears, they keyboard won't work, and neither will the icon to pull up the on-screen keyboard. Otherwise my mouse can click around just fine. I can only log onto a non-password protected account. *Generally, logging into as different Windows user fixes it. I can then log back on to my main user account and continue work for a few hours until it happens again. *Clearing my Chrome browsing data stopped the problem from recurring for a week or so. *I use Avira free antivirus software, and repeated scans turn up nothing fishy. *I have already REINSTALLED Windows 7 (not just a restore.) The problem returned after 2 days of use. The only thing I suspect is something in Google Chrome -- I used my google account to reload all my previous Chrome extensions, saved data, etc. (Chrome Extensions Installed: AdBlock, Better Google Tasks, DropBox, FB Photo Zoom, Google Mail Checker, StayFocusd.) Any ideas? Any at all?

• UPS power requirements for server

  - by captainentropy

  Greetings! So, I just placed an order for a new server. The company recommended that I get a 3000W UPS. (!) As best as I could I calculated the following wattage consumption based on benchmarked data or datasheets provided by the manufacturers of each component: number watts **total watts** MoBo 1 240 240 CPUs (E5540) 2 80 160 RAID cards (3ware) 2 18 36 RAM (6x4GB) 6 3 18 DVD drive 1 7 7 floppy 1 2 2 RE4 drives 8 7 56 WD20 drives 8 6 48 Intel X25 SSD 2 0.15 0.3 total = 567 So that is for the PSU requirements only. The PSUs in the machine are a 720W for the master node and 800W each for two subsystems. That's a total of 2320W that can be delivered by these PSUs. But that is 4X the amount being consumed, at most, by the components. I didn't count case fans or the eSATA card (3W maybe?) or what the PSUs themselves require but assuming I double or triple my calculations I'm not even remotely close to the 3000W UPS I was suggested to get. They run at least $1100. I could get a 2000W for about $750 or a 1500W for $450 and still be well over my estimated power need. I don't think I need a whole lot of run time in the case of a power outage, maybe 20 minutes max, enough time to shutdown if the power doesn't come on within 5-10 minutes. Any thoughts? Am I off on my calculations? Did I overlook something major? If so what are your suggestions for a UPS? Thanks!

• Docking Station Sound Doesn't Work on Dell D830 with Windows 7

  - by cisellis

  I have a Dell Latitude D830 laptop that is running Windows 7 Enterprise x64. I connect to a docking station during the day with multiple monitors, a keyboard and a mouse. Everything runs with no problems including most of the docking station ports (usb, monitors, etc.) However, the sound port from the docking station does not work since the upgrade to Windows-7. Even with the laptop plugged in, the sound always comes out of the laptop, not the headphones plugged into the docking station. Here's what I've tried: I've seen other issues like via Google this that seem to be mostly unanswered. I found one or two that referenced using the Vista x64 drivers, especially the Nvidia drivers. I do not have an Nvidia chipset but I've reinstalled the sound drivers and that has not helped. I don't have a support contract and considering the cost is usually high to call Dell, that's not an option. Dell's forums are pretty much a wasteland and I've found no help there. Since this is a docking station I thought I might need to try the SATA or Intel chipset drivers from the dell site instead, however I'm not really sure and I need to work on this laptop in the meantime. I can't really afford the downtime to experiment with random drivers all day in case they turn out to be incompatible (Dell still hasn't added Windows 7 to their support site as far as I can tell). Does anyone have any other ideas? Has anyone had this issue and solved it? If so, how? Thanks in advance for your help.

• What are these CPU cache settings? Snoop Filter, ACL prefetch, HW prefetch

  - by eater

  I was in my BIOS setup turning on VT-x support today and saw these other settings. A little googling indicates that they each seem to turn on some sort of optimization to do with the CPU's L2 cache. They were all turned off by default. The processor in question is an Intel Xeon quad-core 3.4GHz (X5492). My OS is Linux 2.6.35.10-74.fc14.x86_64 #1 SMP Thu Dec 23 16:04:50 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux. I have 4GB of RAM if that matters. Here's what the BIOS manufacturer has to say: Snoop Filter Enabling the snoop filter typically improves performance by reducing snoop traffic on the frontside bus in dual processor configurations. Well I like the sound of improved performance. Why would the BIOS have this off by default? Or by dual processor do they not mean multi-core? Regardless, is there a downside if this is on? ACL Prefetch When enabled, the Adjacent Cache Line Prefetcher fetches both cache lines that comprise a cache line pair when it determines required data is not currently in its cache. When disabled, the processor will only fetch the cache line required by the processor. HW Prefetch Fetches an extra line of data into L2 from external memory. Both of these sound like optimizations that have some drawbacks. What are the reasons to turn them on? What are the reasons to leave them off. Why is the default off?

• Best way to build / implement a corporate developer Linux distro with multiple kernels?

  - by Garen

  At work we have Linux users who understandably prefer using Ubuntu. Problem is, we also have developer tools that only work with 'officially' supported Linux distributions that use much older 2.6.18 based kernels. (And even if they worked with newer ones, the vendors could always say they won't "support" the software unless it's on one of their 'officially' supported platforms.) We could of course just tell them to use CentOS or something else 2.6.18-based, and I'm sure their response would be something like: "you can take Ubuntu from our cold, dead hands." :) Which brings to me some questions--is there any good/easy/recommended way to run something like Ubuntu as a host VM and Centos 5.x as a guest OS (with which system--Xen,KVM,VMWare, ...?), and then roll that into our own custom internal distribution that could be easily installed? KVM looks like a good high-performance option just recently included in RHEL 5.4, but if hardware support for virtualization like Intel-VT or AMD-V is necessary, then I'd guess only those folks with fairly new PCs will be able to do it. Would be very interested to hear how anyone else has addressed this kind issue. EDIT: The target audience / users of this kind of system would be developers, each one needs to run locally licensed commercial software, so building out some separate beefy central machines isn't an option unfortunately due to license restrictions. Even if that weren't the case, a couple developers could quickly eat up the resources with parallel builds. :) Ideally, I was hoping there was some step-by-step guide out there to build your own pre-built distribution that had e.g. CentOS 5.x and Ubuntu Desktop as a guest.

• Laptop Randomly Turning On and Off

  - by Ian Mallett

  So, I have a pretty new laptop, and one of its quirks is that, at random times (though typically in the middle of the night), it seems to wake up from sleep mode, churn a bit, and then go back into sleep mode. I write "seems" because its fans are very loud, so it's obvious when it's not asleep, but during the time it is "on", I can't see anything on the screen. I have researched the problem somewhat, and could only find similar issues; nothing identical. In those cases, it appeared that certain devices could be responsible. Nothing is plugged into my computer during this behavior, but I nonetheless disabled every device's permission to wake the computer through the device manager. This included disabling the magic packet wake for the network (despite its only having a wireless connection). Using "powercfg /lastwake" gives an empty wake history. But, I also went through all the tasks and checked if they would wake the computer. None appeared to. The problem persisted, so, after some more research, I found this, and executed it for all power schemes on the computer. The problem persists.

• How can I determine what is killing my network adapter win7 or vista?

  - by datatoo

  I thought this issue was like another person here, and that downloading the nvidia chipset drivers was the solution. However that is not all that is going on. This machine had Vista 64bit and is now Win7. Same issue with both. I have explicitly been denying network driver updates since getting things working again and when a Windows updates occurs on seemingly benign Office updates the adapter fails to work. Is the update process somehow protecting this machine by turning off things and it fails to recover connectivity after a restart? All that seems to ever work is a system restore. Which does work. Since there are 25 pending updates asking to do there thing, I hate to think this is a one by one update test to find the culprit. Any ideas? This has an integrated nic, video, and I guess audio on the motherboard. ES5200 intel cpu on a gateway 4800-05e I am not quite sure how to determine the actual network adapter. This is a wired adapter. I suppose worst case I can try another adapter if this keeps happening.
