• Windows 7 pagefile size with large RAM and SSD

  - by Avi

  I've just upgraded my Windows 7 machine from 12GB to 24GB - both for running more VMs and for future proofing. My C driver is an SSD with 129GB formatted size. I was surprised to find out that the SSD only has 68GB free (most of my files are on D: to G:). Researching I found 24GB of my precious C: SSD are taken for virtual memory. So - do I need such large amounts of virtual memory when I have 24GB or RAM? I bought this size of memory so I"d not have to go to disk...

• Can't decide on a new distro

  - by Alex W

  I've had Ubuntu (9.10) on my netbook in the past and I really liked it. I'm currently running Fedora and feeling like I should "change it up" again. I've played around with Ubuntu 10.04 Lucid a little, and so far I'm very impressed. I've always wanted to try Arch, but I'm worried I won't have the driver support I need for all the non-standard hardware in a netbook. Does anybody have a suggestion for a new distro to try? I'm preferably looking for something feature-rich over light-weight, and something that I can have up and running with a minimum of configuration (at least partially working). Thanks!

• Is it possible to live-boot VirtualBox from a USB flash drive?

  - by bw.

  To clarify, I'm not asking if you can boot from USB from within VirtualBox. I would like to make a portable version of Windows 7 that I can run from a USB drive on any machine. I'm putting a distro of Linux on my laptop, but I manage a Windows domain at work so I'd like an easier management solution than trying to use Linux tools to interface with a Windows DC(as RDP to a DC is not always an option). The reason I'm inquiring about VirtualBox... I plan on carrying this portable installation with me and using it on multiple machines, so I would like to avoid driver conflicts (which I imagine would happen if I only installed Windows on a flash drive). Basically, I need a way to boot an installation of Windows 7 from USB that still allows me to install/remove/update programs as if it were installed on a standard hard drive, and not freak out over different hardware configurations. Please help, superusers!

• What sort of things can cause a whole system to appear to hang for 100s-1000s of milliseconds?

  - by Ogapo

  I am working on a Windows game and while rendering, some computers will experience intermittent pauses ("hitches" for lack of a better term). When profiled they appear in seemingly random places in the code. Eventually I noticed that it wasn't just my process that was affected, but (seemingly) every process on the system. All of the threads in my application hitch at once. The CPU utilization drops during these hitches and it appears as if most processes make no progress. This leads me to believe this may be an Operating System or Driver issue, but it only occurs while playing the game (and only on some systems). What sort of operations might the operating system be doing that would require the kernel to pause all user threads and block. Some kind of I/O? At first I thought of paging but my impression is that would only affect a single process, no? Some systems in use: Windows, DirectX (3d), nVidia cards (unknown if replicates on ATI), using overlapped io for streaming

• Audio Line-In on Ubuntu/Linux Mint

  - by hahuang65

  I'm currently on Windows, and want to switch to Linux, but some hardware issues are preventing me. Mainly, I have a sound card that supports Line-In. On Windows, anything I plug into the line-in gets outputted to the speakers. However, when I installed Linux, because there is not a control application that comes with the driver, I have no idea how to set this up. I tried going to the sound settings and it doesn't seem to be there. I also want to configure it for 2.1 sound, and do not know how to do that... Anyone here done it before? Thanks in advance for the help!

• Creating bootable Fedora USB with persistent storage

  - by dooffas

  I am attempting to burn the full Fedora 19 x86_64 DVD iso to a USB drive and have a separate partition on it for a kickstart file / other media that will be installed in the kickstart process. With the Ubuntu server 12 iso, you can simply dd the iso to the usb drive: dd if=/path/to/iso of=/dev/sdb Once the iso has been burnt, open gparted and create a ext2 parition in the allocated space. However, this does not seem to work with the Fedora ISO. When loading the USB drive in gparted I get a warning and an error: Warning: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes. Error: The partition's data region doesn't occupy the entire partition. Ignoring both of these errors allows gparted to load the usb drive, however it shows a blank drive with no partition table. Has anyone come across this before? From what I have found, it may have something to do with the fact that Fedora use isohybrid.

• Converting an Small Business Server to a Workstation

  - by noway

  I am planning to buy a Dell PowerEdge T110 Server and convert it to workstation similar to Dell PowerEdge Precision T1700. The reasoning behind is the cost, if I do it by myself, it costs two times cheaper. However, I wonder what might go wrong in this way? The things I have thought of are: Client OSes are not officially supported. There might be some driver problems. The chasis is designed to be a server case, so there are not many useful inputs in the front side of the case. The server boots slower than usual PCs. What might else be a problem?

• What is causing my wireless problems?

  - by user34629

  I have a Dell XPS M1330, since I moved to my new house, the wireless barely works on it, my housemates report no problems, so I guess it's something to do with my laptop. It's eratic in normal mode, sometimes not working for days, usually working on-and-off, forcing me to reload pages a few times before they work, etc. It works perfectly in safe mode, the driver I'm using is the Intel PRO/Wireless 3945ABG Network Connection, version 12.4.4.5, with a date at 26/10/2009, the most recent one I could find, bluetooth is not enabled, and I'm running Vista 32-bit Home Premium, which it shipped with. I also tried disabling IPv6 and resetting the IP stack, both to no avail. Can anybody help me?

• Installing drivers and getting -> Error Code 28

  - by Adrov

  I've recently upgraded mainboard, without reinstalling OS, so I guess that's the issue. I really don't want to install OS at this moment. Issue is I can't install USB drivers, if I right-click uninstall, just installs same driver, which isn't working ofc. and giving error code 28. I fixed such issue once long long time ago, with editing registry, but I really can't remember what and where I have to do, so if anyone know please let me know, I'm also open to all other solutions to this issue. http://i.stack.imgur.com/AuBtB.png

• Why am I seeing red dots on my LCD screen?

  - by mydoghasworms

  My laptop is about 2.5 years old. Now I am starting to see red dots on certain shades of colour (mainly dark colours, blues and blacks), and it is not limited to certain pixels, because when you move a window around, the red dots move with it, staying on the certain shades of colour. Is this a problem with the LCD screen, or is it the GPU? Is there a way to determine this? It is clearly not a driver issue, because it happens in Linux and Windows, and my Windows setup has not changed prior to the issue starting.

• Can't set up printer

  - by Jason Swett

  I'm trying to set up an HP OFficejet Pro 8500 A909a on my Windows XP machine over the network. I know the IP address of the printer but it's unclear to me how to set it up based on that. I have no idea how to troubleshoot this problem. I've tried installing the drivers but when I do that it tells me the printer is on a different gateway from my workstation, which is not true. Also, other people in the office are able to connect to this printer just fine, although the driver apparently didn't work for them, either.

• MySQL has stopped accepting connections from other users than root

  - by John

  Hi there. I'm running a mysql-server a long with apache and tomcat on a Gentoo box. To administer mysql I'm using phpMyAdmin. A couple of hours ago I received a call -- a user was unable to login to phpmyadmin. I logged on to phpmyadmin with the root user, and reset the password. The user was still not able to login. I then decided to give it a go myself, and even I wasn't able to login. I tried creating several user accounts, none of them were able to access mysql via jdbc/mysql-client/phpmyadmin. The only user that seems to work is root. What's even more strange is that websites that connect to mysql with a user other than root are still able to login and retrieve content from the database (it's mainly wordpress and a tomcat webapp). I have made sure it's not just cached, I was able to post SQL queries to the database via these web apps still. However, I am unable to login to phpmyadmin/mysql-client with this user and I am also unable to set up a connection with this user for any new web-applications. Any help is immensely appreciated.

I tried with KERNELS=="6*" etc.. to no available any ideas ? thanks

• How to add network printer remotely without knowing the IP?

  - by Steve

  Assume your friend from over 100km away asked you to add a network printer to his computer since you're so tech savvy. How would you add network printer remotely in this case? You would need: 0. Remote connection to your friend's computer 1. Printer IP and brand/model names 2. Respective drivers downloaded either from manufacturer's website or Windows Update driver Question is, how would you find out the IP address of the printer without bothering your friend too much with technical steps? Since your friend isn't as tech savvy as you - they wouldn't know which buttons to press to get IP address.

• Can most Intel processors run 64-bit Windows 7?

  - by Jian Lin

  Can most Intel processors run 64-bit Windows 7? Such as all the i7, i5, Core 2 Duo, Dual Core, Single Core with HT, and even just Single Core? I think a popular view is that if you can run 64-bit Windows 7, then use it? It might have driver compatibility issue but if there is no device hooked up, then there is no problem? What about some software / games not compatible with the 64-bit version or may run slower? thanks. update: a couple of my machines have 4GB RAM. so 64-bit Win 7 can make use of the full 4GB RAM instead of only about 3.2GB

• How to get the CentOS 5.6 alsa drivers which will really work with one shot, without any internet.

  I have one chance to install this in my server on site. Server that i am running is CentOS 5.6 (Dell R310, RAID1) where i need to install alsa-sound driver so that anything related to audio recording from rtsp is working (rail station/rail passing video recording including audio, where audio is not working). Unfortunately i do not have any kind of internet in that odd none human location so yum will not work for me. I need a offline way to install alsa drivers including missing dependencies if arise. What and where i can download this to my usb or cd? so that i can successfully install it (like mission complete). Thanks

• How to record audio in Windows Server 2008 Web SP2?

  - by Aurelio De Rosa

  I face into this problem and before ask here I've searched and read a lot of question but no-one seems to fit to my problem. I have a server running Windows Server 2008 Web with the SP2 and a headset attached to it using audio jack. The server has audio driver since I can listen audio. This OS does not came with the built-in audio record tool (the one I have in Windows 7). I can access physically and remotely (using RDC) to this server with administration permission. My local pc has Windows 7 if it can help. All I want to do is to know if it's possible and how to record audio form the microphone (of the server) and store that file in the server from remote connection. I tried to install several software on the server but everyone fails with a different issues (missing DLL which if I put in the system the error doesn't go away).

• Ctrl Alt Left/Right moves mouse - how to find responsible software?

  - by Unimatrix02

  Hi, I've got a bit of a strange problem. On one of our computers, pressing ctrl + alt + left/right/up/down will move the mouse pointer on the screen, but it's not clear which software makes this happen. It interferes with other software that uses these shortcuts. I've already tried disabling some software, such as WinKey and a Kensington mouse driver, but that didn't make a difference. It's happening on a Windows XP SP3 computer by the way. Does anyone have an idea of how to find the software that traps this shortcut? Suggestions for actual (types of) software that might be doing this are welcome too. Thanks!

• Why do I have inconsistent network issues with my laptop's wireless?

  - by Jason

  I'm having trouble with my laptop Internet connection. It's patchy at best and resets or freezes a lot. The signal strength is also random. I thought it might be a driver issue but now I don't know. Three other computers using the same wireless network run well. I've switched out wireless routers so I don't think it's the router. I thought it might be the laptop's internal wireless card but I just bought an external USB network card and I'm still having problems. Specs Lenovo T-60p Windows 7 Ultimate Edition Patches/drivers are up to date I only use one of the below at a time, disabling the other: Intel PRO/Wireless 3945ABG v. 13.3.0.137 (Internal wireless) Medialink Wireless-N USB 2.0 Adapter (USB wireless) Any ideas on what might be the problem?

• Linux, PHP, and mysqlnd?

  - by bob-the-destroyer

  Looks like most common distros build their PHP packages without mysqlnd, instead relying on the old libmysql library. Are there any distros that do include the new mysql native driver even as an option in any of their officially supported repositories? If not, is it possible (and if so, how) to rebuild these three (mysql, mysqli, & pdo_mysql) extensions without having to rebuild the entire PHP install? In my case, there are several PHP functions I need that are available only if these Mysql extenstions are built against mysqlnd. So I'd be fine installing a new OS to get these if the OS offers and supports it.

• IntelliPoint & Intellitype upgrade to Mouse and Keyboard Center causing system freeze?

  - by Kent England

  I allowed Microsoft to upgrade my wireless keyboard 6000 v3.0 and mouse 6000 v2.0 from Intelliyada v 8.20.468 to what appears to be v9.1.486. This was some time ago, so I can't be certain but this upgrade might be causing my system to freeze on the logon screen (user selection) in Windows 7 Home Premium 32-bit. Mouse and keyboard don't work, but system seems to be running underneath. No indication in Event Viewer about keyboard/mouse driver issues. Might be problem with transceiver hardware. I now have the "Microsoft Mouse and Keyboard Center" UI which isn't very helpful (seems to be very metro) in debugging these drivers. I'm just looking to see if anyone else had problems upgrading to this new Intelliyada software for their MS keyboard and rodent.

• ALT+TAB doesn't work properly in Windows 8.1

  - by Marco1

  Holding ALT+TAB will activate the flip 2D to switch from a window to another. The problem is that this function remains active for a very short time and I'm not able to select the window I want in the foreground. I also noticed that when I put the cursor on an icon on the taskbar, the live preview thumbnail disappears quickly. With a safe mode restart the problem is no longer there, all is fine! With a clean install of Windows 8.1(no driver and applications installed) the problem is here again; obviously disappears with a safe mode restart also in this situation. What's the problem? A Windows process or service?
