• for what reason live USB linux images are not 100% persistent?

  - by gcb

  I understand that during CD-R times non-persistence had a purpose, but what's the purpose now that pretty much everyone uses USB flash drivers? not to mention USB3 sticks are pretty much 4x faster than my HD raid. I'm writing this while taking a break going over the linux from scratch guide... And i'm still baffled that this is not the norm already with all live images. So, Is there any reason (besides historical) that i'm missing and that will bite me after I finish this ext3-rw image?

• Force the computer to always use current display settings

  - by sazpaz

  So I'm having a terrible black screen problem with my new installation of Windows 8. The screen basically goes to black every time I turn it on or sleep, or connect to an external or monitor. I dont really know what steps actually cause the problem and cant seem to figure what steps allow the screen to come back, besides forcing restarts, going to sleep and waking up, and smashing Win + P. I have a strong feeling it's because the Switchable graphics I have (Intel HD + Radeon 5060), so I'm looking for a way to make the computer always use a specified mode (i.e the current mode I'm on, that does show stuff on the screen) and force it to use it everytime? Any ideas? EDIT: I've Installed all the latest drivers I've found. Tried most of the solutions around the web for this problem. Updated the BIOS to UEFI (from HP Support Assistant), etc. Laptop is an HP- Envy 14

• If I split my harddrive, will a system restore delete it?

  - by AoiHana

  I split my 1TB HD from C drive and called it A. I put some files there to back up. I have now come to a point where I need to run a system restore with the discs that came with my computer. If I do a system restore and wipe C drive clean, will I lose the part of the hard drive that I split or will it remain intact and my files uncorrupted? This is a partition I created with windows myself, and dragged files over to it. Thanks!

• Engineers are using explosives to remove hard rock outside our office building. What countermeasures should we take?

  - by Karrax

  Our building is located approx. 100 meters from the explosive charges. They happen several times per day, and really shake the entire building a lot. This is going to go on for many days and the blasts are supposed to get stronger. Our server rooms are nothing fancy; one of them has all the racks on hard concrete while the other one has a raised floor (the one which allows the cables to go beneath it). Does anyone have any tips, countermeasures or best practices for us? Currently we are thinking of the following countermeasures: Daily report of the server rooms status lights (HD lights, power supplies and so on). Nightly check disk scan on the most important servers Order in extra supply of spare harddrives Edit: Many good answers here! However one needs to be accepted. The highest voted answer at the time of this edit will get their answer accepted.

• Windows 8 Radeon update broke some games

  - by Andrew

  I've been using Windows 8 Consumer Preview 32-bit on my desktop for months, and recently did a software update through Windows Update. An update for my Radeon HD 5450 driver (Catalyst) to WDDM 1.2 was in the list of updates, and installed. When I went to play CS:GO and discovered that when loaded, it would not display the GUI (menus, sometimes even the background) after a few seconds of flickering GUI. I can still navigate the menus 'by feel' and connect to and play on servers, but have no GUI, no buy menu, no map, no cross-hairs, no health indicator, etc. I have tried CS:S, which works, and Borderlands, which doesn't even load the intro videos before the first menu screen. I've tried re-installing Catalyst from the AMD website, and the beta, and tried uninstalling and reinstalling CS:GO. The problem with it (and Borderlands) still happen. What broke, and how can I fix it? I'll be reinstalling soon anyway to dump Windows 8 back to 7, but would like to be able to game until then.

• Fullscreen Video stutters on second monitor laptop

  - by nobrandheroes

  Fullscreen video on my new 1080p monitor is choppy when it comes from my laptop. The same video plays when not full screen. This goes for all video(Flash/MKV, etc), regardless of video resolution. I have an ATI Mobility Radeon HD 4200 Series card in my Thinkpad Edge, Turion X2 2GHz. The computer plays 1080p fine. Things I've tried: Updating Drivers Switching cables Turning Hardware Acceleration Changing video players process priority Rebooting Turning of laptop screen Turning off unused processes Nothing Works. What is the likelyhood that my laptop cannot power a 1920x1280 display?

• Restore Windows 7 bootloader after Windows 8 install

  - by JMK

  I have installed Windows 8 onto a partition after Windows 7, and when I turn my PC on, Windows 8 basically loads completely, and then I get the option to choose my OS. If I select Windows 8, I go straight to the lock screen, if I select Windows 7, my computer completely restarts and then boots into 7. I want to use the Windows 7 installation DVD to restore the Windows 7 bootloader using the method described by the How To Geek but I am worried that if I do this, Windows 8 won't boot. Can anybody advise on whether or not this will work, and if not how can I go back to selecting the OS right after the BIOS loads?

• Linux and GeForce 8400 dual monitor

  - by Andrea Polci

  I'm trying to install a linux distribution on my PC. I have a GeForce 8400 GS with two connected monitors. I tried with Fedora 12 and Ubuntu 9.10 (both 64 and 32 bit) and the live cd cannot boot properly. I don't get a visible error on Ubuntu, it simply hangs up during the boot. With Fedora I get this error: [drm] Modeset on unsupported output type [drm] Table 0x0000 not found for 1/1 using first I tried to disconnect one of the two monitor and was able to install on my HD and boot from there, but if I try to connect the second monitor again I cannot boot. Do I need to install something else? (a driver for my video card for example).

• unable to install new versions of linux on my PC

  - by iamrohitbanga

  I have an MSI-RC410 motherboard with onboard ATI Radeon XPress 200 series Graphics card. I have used OpenSuse-11.0 on my PC for over an year. but when I tried to upgrade to OpenSuse-11.1, I managed to install it only to find that several features were missing. for example /dev/cdrom was missing. Also install DVD of Fedora 11 did not work. I have also tried Ubuntu-9.10 live cd. When I boot from the CD i get the initramfs command prompt. Still able to install old versions of these OSs. What is the reason for this behavior? Does it have to do anything with the new version of the linux kernel not being compatible with my hardware? What should i do to install new versions of Linux?

• Can't Use Switchable Graphics

  - by Rev

  I can't get my switchable graphics cards working on my Acer 4820TG laptop. It came installed with Windows 7, but I've installed the RTM build of Windows 8. I have to keep the "Graphics" setting on the BIOS set to "Discrete," if it's set to "Switchable" the screen turns black after the boot animation is complete. The machine has an Intel graphics card and an AMD Mobility Radeon HD 5650, and I know that the Intel card is working. I've seen it work a couple of times with Windows 8 installed, but for some reason it just doesn't anymore. I know that it's not broken, because when I plug in a secondary monitor, and move the cursor to the right, I can see it on that monitor. Are there drivers or something I need to install? I've tried a number of drivers and utilities from Acer's website, none of which have fixed the problem.

• Ubuntu OpenLDAP and Mac OS X Roaming Profiles

  - by Sam Hammamy

  Today, I'm installing OpenLDAP on Ubuntu 11.04. I have gone through the installation before a few times, but what I have never been able to do is use Mac OSX Lion's Directory Utility to administer the LDAP server, and also never got roaming profiles working. SO the question is: 1) Is there a configuration I need in OpenLDAP so I can administer it remotely. I vaguely remember something like that, but I can't find the answer online. 2) What do I need to setup roaming profiles for a mac os x. I'd like to backup all my laptop data to the LDAP's machine, and potentially, also backup with time machine to an external HD mounted no the Ubutnu machine (but that's a few days ahead of time for now).

• Making a Live Thumb drive boot with Persistent files, settings AND *drivers* that load on boot?

  - by Luke Stanley

  I have seen https://wiki.ubuntu.com/LiveUsbPendrivePersistent but it's a mess. What methods support persistent drivers as well as files and settings and don't screw up lifespan of the flash drive? I'd like to see your personal recommendations on say, Portable Linux, USB Creator, Remastersys + Unetbootin, etc Backstory: I have a Inspiron 1525 that's hard drive has been slowly dying. I want to switch to a live USB/CD/DVD system until I can get it repaired but my laptops internal wifi device requires a network connection by another means for Xubuntu to let it work, and then I have to enter my Wifi key again, and THEN I have to reinstall Skype etc... I'd be damned every time I have to shut the laptop down. I'm ok with making a shell script for installing apps and copying settings as required but a good persistent install should make this old hat and slow and it doesn't take care of drivers. The last time I tried making an ISO with Remastersys it didn't seem to copy all the required settings.

• Why would only the cpu fan not spin and no video displayed?

  - by Patrick

  I just built a new computer and when I first powered it on I got a continuous beeping which according to the manual means a power failure. After moving the voltage switch to the left a little I was able to get the beeping to stop. Even after the stopping though the CPU fan doesn't spin, and there is no display on the monitor. All the other fans and lights come on in the computer though, the DVD drive is working and ejects the tray, and the hard drive sounds like it spins up. Has anyone seen this before and know what is wrong or what has failed?

• Firefox 3.5.6 Uninstaller not working

  - by Wesley

  Hi all, I want to uninstall Firefox 3.5.6 in favor of Opera 10.10. However, I've went into Control Panel Add or Remove Programs and tried clicking Remove from there, but nothing happens. I go into the Program Files for FIrefox and find the Uninstaller folder and click the helper.exe found in there. Still, nothing happens. Is there some possible way to uninstall Firefox without screwing up the rest of my computer?

• The cleaner way to upgrading a Mac

  - by AngryHacker

  This page list a way to do a clean install of Snow Leopard without loosing any of your settings. This sounds pretty darn good since my mac did get a bit slower over time. The method basically involves copying your existing drive to an external one, then doing an Erase and Install from the installation DVD. After the installation, supposedly, I'll be presented with an option to migrate settings from another Mac. I am not all that familiar with the Mac, hence what is probably a simple question. With this migration option, will I be able to copy over all my applications or will I have to reinstall them from scratch?

• Install 64-bit Windows 7 on Mac Using Bootcamp

  - by Paul Lefebvre

  Has anyone been able to install Windows 7 x64 under Bootcamp on a Mac? I was able to get the 32-bit version to install, but I cannot get x64 to install. The Mac doesn't seem to even want to boot the DVD. And even if I get it installed are there drivers that will work with it? I'd prefer to have Windows 7 x64 because I'd like to use the entire 6GB RAM in my MacBook Pro. I'd appreciate any tips or advice.

• Computer still in boot loop

  - by user2856410

  My computer is in a boot loop and despite all my efforts, I haven't been able to load windows XP with it. When the computer loads, I see some white loading bar at the bottom, then the windows XP loading screen, then the DELL boot screen, then windows XP loading screen, and it just keeps looping. The blue screen error is: UNMOUNTABLE_BOOT_VOLUME Stop: 0x000000ED (0x823D6C08, 0xC000009C, 0x000000000, 0x000000000) I have booted using Hiren's mini XP, and ran CHKDSK /f /r, but it didn't affect the boot loop. Is there anything else I can try to get my computer to start up? I don't have my windows XP disc, but I have a dvd burner on another computer, and can burn a downloaded ISO if it could help me get out of this loop. Thanks!

• Raid0 performance degradation?

  - by davy8

  Not sure if this belongs here or on SuperUser, feel free to move as appropriate. I've noticed the performance on my RAID0 setup seems to have degraded over the past months. The throughput is fine, but I think the random access time has increased or something. In use I generally see about 1-5mb/sec when loading stuff in Visual Studio and other apps and it doesn't seem like the CPU is bottlenecking as the CPU utilization is pretty low. I don't recall what Access Time used to be, but HD Tune is reporting 12.6ms Read throughput is showing as averaging about 125MB/sec so it should be great for sequential reads. Defrag daily and it shows fragmentation levels low, so that shouldn't be an issue. Additional info, Windows 7 x64, Intel raid controller on mobo, WD Black 500GB (I think 32mb cache) x2.

• What is the best way to clone Win7 machines?

  - by John Hoge

  I'm looking to buy 5 new Win7 boxes and would like to ease deployment by cloning the OS. What I would like to do is install a fresh OS (Dell doesn't seem to sell machines without preinstalled crapware anymore) and then install a few apps on the first one. Once it is just right, I want to clone the OS and install the image on the other four machines and just change the machine name. Is this possible to do without any extra third party software? What I am thinking of doing is backing up the disk image of the first machine to a network share, and then booting the others to the windows install DVD and restoring the same image on each machine. Has anyone had any luck with this technique?

• Swithing from Windows to Mac OSX - Application recommendations

  - by roosteronacid

  My new Macbook Pro 13" notebook should arrive this monday. And I can't wait! I am a long (looong) time Windows user. And after a good week of researching, I am still somewhat in the dark as far as which applications are "must-haves" on Mac OSX. I would be very greatful if you guys would recommend your favorite applications. I'm looking for recommendations in the following categories... General use applications: File-compression applications, peer-to-peer applications, CD/DVD ripping/burning applications, messaging applications, etc. Web-development applications: Code editors, graphic design applications, and everything in between Must-have-cannot-live-without applications: Things like Growl and other applications that live within Mac OSX's preference panel Virtiualization applications: VMware Fusion, Parallels, etc.

• powertop keeps telling me to turn off the same thing, over and over

  - by Rory McCann

  I am running an ubuntu lucid laptop on battery. I want to make my power last as long as possible. Aswell as the normal things like turn down screen brightness, and turn off wifi, I'm using powertop. It will sometimes tell me things, e.g.: Suggestion: Enable USB autosuspend by pressing the U key OK, I press the U key to do that. However a few minutes later it will give me the same suggestion, it's as if it never enabled USB autosuspend the first time. It does this for other things aswell, not just USB autosuspend. e.g. it'll give me this message frequently: An audio device is active 100.0% of the time: hwC0D1 LSI ID 1040 Q - Quit R - Refresh A - Turn HD audio powersave on Is there anything I can do to make these choices 'stick'? Or do I have some unfortunatle hardware that won't obey linux? (If so, is there any way to confirm this?)
