  • Random flickering on 2.6.32 kernels after suspend

    - by whitequark
    I have XUbuntu 9.10 installed on a Toshiba NB200 netbook with Intel video card that's handled with i915 driver. With 2.6.31 stable, recommended kernel everything but WiFi works fine: Atheros ath9k WiFi shows too small signal power and loses packets in 'bursts' sometimes. With 2.6.32-* (I tested -9 to -11 from Ubuntu's kernel unstable ppa) everything works fine just prior to first suspend: echo mem >/sys/power/state. After it random unidentified fullscreen 'one-frame' flickering begins in Xorg, and after a couple of minutes everything eventually hangs while showing filled grey (not white; it is like default button colour) screen; no X keys are working: Ctrl+Alt+Fn don't, blind typing in console too. Magic SysRq still works and I was able to reboot. Also there is one out-of-tree kernel module called omnibook that is required to turn on WiFi and Bluetooth. Any advices?

  • What was your most expensive computer rig?

    - by AlbertoPL
    I'm curious as to how much people are willing to spend on a typical computer. My most expensive machine is a gaming rig complete with an ATI Radeon HD4850, Wolfdale 3.0 GHZ Intel Core 2 Duo, 500 Gb hard drive, Antec 900 computer case, the works. I also have a 2-monitor set up. I'd have to say this thing has cost me a little more than a grand at this point, and I'd put the total value of the components at roughly $1300. So, how far have you gone with your computer rigs and has it been worth it?

  • Laptop hardware recommendations for multi-platform development

    - by iama
    I am thinking of buying a laptop with the following configuration - Intel core 2 duo(or I3-330M)/ 4GB RAM/300+ GB 7200 RPM. I would like to be able to run two server VMs on this laptop with Win2K8 and Ubuntu (preferably 64 bit editions). Windows 7 will be the Host OS since that is the one that ships with the laptop. I am thinking of using VMWare player to run the two server OSs. Is this laptop good enough to run the two VMs side by side or do I need to go for a better configuration? Any suggestions? Thanks.

  • Improve performance of bind9 service restart

    - by Jakob
    Hi, I'm setting up a name server hosting DNS for a large number of domains, 50,000 - 100,000 domains. I will be using Bind9 and the service will need to be restarted several times a day. I have made some tests and it seems that restart of the Bind9 service scales very poorly with the number of domains. #domains | restart time ----------------------- 10,000 | 3.1 sec 25,000 | 8.9 sec 50,000 | 50 sec 100,000 | 7:50 min Is there some way to speedup the restart of the service? I have noticed that restart only utilizes one core, is there some way for it to use more cores? The Bind9 version is 9.7.1-P2 with default configuration. The server running Bind9 is a Intel Core 2 Due 2.93 GHz with 4 GB memory and Ubuntu Server 10.10. Any help will be appreciated. Jakob

  • Create a CDROM Bootdisk to update BIOS

    - by osij2is
    So, I have a Tyan Opteron board with a very old BIOS version. I realize Opteron's aren't exactly common like Athlons, Phenoms, Intel CPUs, etc. but my question revolves around updating the BIOS, however I don't have a floppy drive and there's no option to boot off of a USB key. Tyan has incomplete instructions on their website (link) on how to flash the BIOS via USB. So my second tactic has been to create a Windows 98 boot-able CDROM with the flash utilities on it. It's been years since I've made one but after going to sites like bootdisk.com and such I haven't had any success. Can anyone tell me step-by-step how to make a boot-able Windows 98 CDROM? I can't believe I'm having such a hard time doing this but I've failed on four different attempts and I must be doing something wrong or I'm not accounting for something.

  • Safari 5 fails to install on my Mac

    - by Amairani409
    I just got the new Safari 5.0 I downloaded because my Mac told me there was a new version that I should be getting. But when I try to run this new version of the application -- nothing happens! I mean the program seems to be working but nothing appears on the screen and so when I try to see my top sites a little window shows up but it just doesn't show anything. Then 3 seconds later the program shuts down! I don't know why this is happening; ideas? Mac OS X version 10.5.8 2.66ghz intel core 2 duo 4gb 1067 MHz DDR3

  • Multi-monitor setup: one widescreen monitor, one regular (4:3) monitor; is this usually possible?

    - by stakx
    I'm trying to find out whether it's generally possible to have a multi-monitor setup with both a widescreen monitor and a regular monitor (ie. one with a 4:3 picture ratio). I'd like to run them in Extended Desktop mode on a Windows Vista machine. The computer is a Dell notebook with an onboard Intel GMA 4500MHD graphics chipset. While I know that this notebook is capable of driving multiple monitors, I don't know if it is also able to drive monitors with varying resolutions. Does anyone know if differing screen resolutions is generally a problem?

  • Computer becomes very slow (permanently) after running a bunch of apps

    - by djzmo
    Hello there, My computer with Windows XP installed becomes very slow after I ran some heavy tasks at a time. (play a full 3D online game while extracting a 4GB RAR archive) It freezes for about 200~500ms every few seconds, and this always happens if I do heavy tasks at once in my computer (for example, installing a program while playing games), and the lag remains permanently (even a reboot won't make it better) unless I repair-install the Windows. Since I have a low-end computer: Intel(R) Pentium(R) 4 CPU 2.00 GHz, 512 MB of RAM ATI RADEON 9550 AGP 256 MB And the only way I used everytime to fix this problem is by repair-installing my Windows XP. So that I won't lose any data or installed programs. But I believe there's a better and faster way to fix this without repair-installing the Windows. Any idea?

  • Building a new PC, Installing XP, blue screen of death

    - by Tim
    I got a gigabyte barebones kit and am installing windows-XP(SP1) and the initial setup works, then it restarts and goes into the second phase of the setup. Then when installing components (I think that's what it says) it gets half way done and comes up with a blue screen saying IRQL_NOT_LESS_OR_EQUAL. BUT! I had gotten past that by installing windows-XP media center addition Now I am trying to install the drivers for my Asus ATI Radeon 5770 graphics card and I get another blue screen of death that doesnt give much info something about address x0000005. Would you think there is something wrong with something in my system or do you think if I got windows 7 that would take care of things? Sorry for probably not giving enough info. Here is what I have MotherBoard - Gigabyte S-series GA-H55M-S2(v) PSU - Ultra 500 watt atx HDD - Sata serial ATA Seagate Baracudda 7200 CPU - Intel i3 Memory - 4gig crucial Graphics Card - Asus ATI Radeon 5770 1Gig DDR5

  • How to avoid Memory "Hard Fault/sec"

    - by Flavio Oliveira
    i've a problem on my windows 2008 server x64, and i cannot understand how can i solve it. i'm looking to Resource Monitor and see about 100 to 200 hard faults/sec. and generally the machine is slow. As i've readed a bit it is caused by a "memory Page" that is no longer available on physical memory and causes a io operations (disk) and it is a problem. The current hardware is a intel core2duo E8400 (3.0GHz) with 6GB RAM on a Windows Server Web 64-bit. Actually the machine have about 2GB Ram used what having 4Gb available to use, Why is the machine requires that high level of Disk operations? what can i do to increase the performance? Im experiencing a memory issues? what should be my starting point?

  • ARM laptop available?

    - by Ken
    Hearing all the fuss about some new consumer product that uses an ARM Cortex A8, I'm interested to get in on some of the action. But I want a real programmable computer running something like Linux. I've seen many, many reports in the past 2 or 3 years about prototype ARM laptops with great battery life. Unfortunately, when I tried googling today, all I can find are the old videos and press releases about the prototypes, not a shipping product. Is there an actual ARM laptop available today? Or did everybody give up and just use Intel Atom chips?

  • xorg DPMS off: keep VT from turning screen back on

    - by Metiu
    I have an embedded board with a small UPS. When AC power goes down, I need to turn off all power hungry devices in order to have a clean shutdown. First thing I do, is set DPMS to force powerdown, then go through the usual SIGTERM/SIGKILL/umount sequence. I have an Intel i915 Display adapter connected to an LVDS LCD panel. Unfortunately, when Xorg dies, Xserver or the VT code turn the LCD panel back on. I even tried working around it by directly poking the panel enable register in the Display chip, so that X doesn't know about it, but the panel goes back on when the VT comes back. Is there any "legal" way of keeping the display off? Thank you

  • What desktop chipsets support AMD's Rapid Virtualization Indexing?

    - by netvope
    Rapid Virtualization Indexing (RVI) is a hardware virtualization feature that can potentially give significant performance improvement. Intel's equivalent is Extended Page Tables. See http://en.wikipedia.org/wiki/Rapid_Virtualization_Indexing for more details. My question is: Does RVI require motherboard or chipset support? If yes, what desktop chipsets support it? I've ordered a Phenom II CPU (which supports RVI) but I haven't bought the motherboard. I'll install XenServer or VMware ESXi (which both support RVI) on the new computer.

  • HP Envy 14, Ubuntu 10.10 and trouble with the graphics cards

    - by Carsten Gehling
    A few days ago I bought a HP Envy 14, containing 2 graphics card: An integrated Intel graphics card, and an ATI HD 5650. I've installed Ubuntu 10.10 32-bit on the machine. Most things work fine out of the box, but the graphics cards are giving me trouble. When booting, I get the message "failed to get i915 symbols, graphics turbo disabled". Then the screen blanks out during the remaining boot period. I am able to get the display working by changing to one of the consoles, then closing and opening the laptop's lid. It seems that Ubuntu gets confused about which card to use. I've read here: http://www.andreas-demmer.de/en/2010/07/18/testbericht-linux-auf-dem-hp-envy-14 that I should be able to turn off one the cards by echoing keywords into /sys/kernel/debug/vgaswitcheroo/switch, but that path is not available on my system. The BIOS does not have any methods to switch of the ATI card. Help anyone? /Carsten

  • Flash player, HD videos and games are choppy

    - by Aimad Majdou
    I have a problem with flash player. HD videos from Youtube or Vimeo and flash games do not play smoothly. I'm using Flash player 11, Windows 7 Sp1, and my graphic card is Intel GMA 4500. Device Manager shows me that all drivers are installed on my computer, so i don't have any problems with drivers. When I run Google chrome, Resource Monitor shows me 15% ~ 40 % of CPU Usage and 40% used Physical Memory, but when I watch a video on Youtube or play a Flash game, the Resource Monitor shows 70% - 90% CPU Usage. Also, when I run some HD Video (Frame width : 1920, Frame height : 1080) on my computer, Device Manager shows me 80% ~ 100% of CPU Usage. before I Reinstall Windows 7, HD Videos and flash games were play smoothly I hadn't any problem with them !! I hope all these informations are enough to answer my question.

  • Remote Installing OS X 10.5 on a PowerBook G4

    - by QuixoticAspie
    I recently acquired a PowerBook G4 (always loved the PPC architecture over Intel when it comes to Apple), currently it has OS X 10.4 installed. Unfortunately I can't find the original 10.5 install disc I had, though I made an ISO of it some time ago, which I've now burnt to a DVD-R DL disc (the SuperDrive is a DVD-R only iirc). This disc keeps being ejected by the PowerBook G4 (reads other discs just fine, except one). So I've been pondering doing a remote install, however the instructions I've seen are for MacBooks - I have DVD or CD Sharing installed, but the part in the instructions (http://guides.macrumors.com/Complete_Steps_to_Perform_a_Clean_OS_X_Reinstall_on_Your_MacBook_Air#Using_Remote_Install) about the 'Install Assistant', I don't get such a thing - only the BootCamp Installer. So my question is: How do I go about doing a remote install on this PowerBook G4? Or is there another alternative, without forking out on a new drive?

  • Vista x64: Improving troubleshoot approach skills

    - by Chau
    I'm not a Windows SuperUser, but neither just the regular user. I don't mind browsing the Registry, using Process Explorer, reading the Event logs, (un)installing new drivers and so on, but all this only makes me solve some problems. I tend though to run into problems where these tools aren't enough. Which tools should I learn about to improve my troubleshooting skills in Windows? Currently I'm using Windows Vista x64 (not moved to 7 yet), facing audio/video stuttering problems and I think this is a good place to improve my troubleshooting skills. I know this post is similar to this question, but my machine is only hanging occationally.

  • Best SQL Server Configuration with this hardware.

    - by DavidStein
    I just received my new SQL Server from Dell. The server will be serve approximately 15 OLTP databases which average 10GB in size. Here are the basic specs: Dell PowerEdge R510 with up to 12 Hot Swap HDDs,LED Intel Xeon E5649 2.53GHz, 12M Cache, 5.86 GT/s QPI, 6 core (Quantity of 2) 48GB Memory (6x8GB), 1333MHz Dual Ranked RDIMMs for 2 Processors, Optimized PERC H700 Integrated RAID Controller, 1GB NV Cache 300GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 4) 600GB 15K RPM SA SCSI 6Gbps 3.5in Hotplug Hard Drive (Quantity of 6) My first thought was to use 3 arrays. OS - Raid 1 - (2)300GB T-Log - Raid 1 (2)300GB DB - Raid 5 (5) 600GB Backup - (1) 600GB - non-raided. However, I could also do the following after purchasing one more drive for backup. OS and T-Log - Raid 10 - (4)300GB DB - Raid 10 (6)600GB The hard drive space is not an issue as the databases are not that large. I'm just trying to optimize the speed of the applications using these databases. So, what would you guys recommend?

  • Optimal Memory Configuration for Dell PowerEdge 1800 (Windows Server 2000 32bit)

    - by David Murdoch
    I am upgrading the memory on a Dell PowerEdge 1800 Server running Windows Server 2000 (32 bit). My Computer Properties currently reports "2,096,432 KB RAM" (4 modules @ 512MB each). Crucial.com scan reports: "Each memory slot can hold DDR2 PC2-5300 with a maximum of 2GB per slot. Maximum Memory Capacity:  12288MB Currently Installed Memory:  2GB Available Memory Slots:  2 Total Memory Slots:  6 Dual Channel Support:   No CPU Manufacturer:  GenuineIntel CPU Family:  Intel(R) Xeon(TM) CPU 2.80GHz Model 4, Stepping 1 CPU Speed:  2793 MHz Installed in pairs of modules." We will be completely replacing the old 512 MB modules. Will there be any performance difference between installing 4 modules @ 1GB vs. 2 modules @ 2GB?

  • Processor not running at max speed

    - by Andrew Hampton
    My laptop has an Intel Core 2 Duo T9300 which should be running at 2.5GHz, however CPU-Z consistently reports my Core speed at right under 1.6Ghz (8x multiplier and ~200MHz Bus Speed). Even when I'm doing heavy development work and the processor is running at 100% for extended periods of time the core speed reported by CPU-Z never goes up to 2.5GHz. My understanding is that this reduction in speed is to save power, but this happens even when I'm plugged into the outlet. Does anyone know why this is happening or how to fix it?

    Hi, I just recently experienced problem with my Photoshop, It seem that it is slowing down when I am doing graphics design. Big or small files ( from 20 x 20 inch 300 dpi of resolution to 800x600 72 resolution ) it is really slowing down. Particularly when I am panning to my project It just get stuck for a few seconds then back to normal with slow movement. Can you guess what's wrong? I have an updated antivirus and I don't think virus is causing it. other adobe suite is working fine just my photoshop. I am running in windows 7, using Intel Core2 Duo 2.40 Ghz and has an Installed Ram of 2 GB. My primary scratch disk has 21 Gigabyte left and the secondary has a 13.89 GB. I need a solution urgently.
