• Does a modern PC require a graphics card to run?

  - by ArtM

  As I can remember, on old systems (Pentium II or III) it was not possible to boot and run the PC if the graphics card was missing (AGP cards were used in those days). Many years from then, I'm using motherboards with integrated graphics and I have no experience related to this subject, the "graphics card" always was present. Currently I intend to build a home/private "server" for my purposes and most of the motherboards I want to buy have no integrated graphics (AMD 870 or 970). I can take a normal graphics card from my firends for a few hours/days and use it when installing the necessary software. The question is: can I boot and run the PC without problems after I install everything I need and the graphics card is removed? if a general answer cannot be given, at least some examples of manufacturers/MB series/MB models will be helpfull I think it's obvious, but for completeness: I mean cheap desktop components, not real servers.

• How to secure a new server OS installation

  - by Pat R Ellery

  I bought (and just received) a new 1u dell poweredge 860 (got it on ebay for $35). I finished installing Ubuntu Server (Ubuntu Server 12.04.3 LTS), install apache/mariadb/memcache/php5 works great but I am scared about security. so far I am the only one using the server but eventually more people (friends, friends of friends) will use this server, use ssh etc... I want to know what can I do to secure all the information and not get hacked, both from the web or ssh or ddos and any other attack possible. Does Ubuntu Server does it for you right away? or I have to fix it my self? Thank you EDIT: I installed (so far): All dev tools ssh server LAMP I didn't install: Graphical interface

• Can I run Win7 virtualized for my HTPC?

  - by Daniel Schaffer

  I'm currently running Vista for my HTPC, and am planning on upgrading to Win7 soon. However, I've been considering installing it as a VM so that I can run Windows Server 2008 and/or Windows Home Server. The single requirement is that the HTPC must boot up to Windows Media Center with absolutely no user intervention. I need to be able to hit the power button have it go. I've got this working currently, so I don't need to keep a keyboard or mouse plugged in - all I use is my remote. If possible, I'd love to be able to do these other things: Use Win2k8 Server as a VM host for Win7 Pro and WHS. This also lets me run IIS7 for doing ASP.NET development Use WHS for all the wonderful things it does for a home network Are either of the two optional things possible while meeting the WMC requirement?

• I think I disabled IE8's compatibility view

  - by malatio

  I have an install of IE8 that doesn't have the compatibility view button next to the url bar. I vaguely remember during install that there was a question about whether it was to be available or not, I may have clicked no. Or maybe that was a dream. There are no options that I can see about it being available or not. Anyone know how to enable it? I'm about to try re-install but I'm hoping I can fix it without re-installing. Version: 8.0.6001.18702 ; Update Versions: 0

• Remote Desktop AND monitor fail on restart (Win2008R2)

  - by Wesley

  I am in the process of building a small 3 server farm. Each machine is running Window Server 2008 R2. As is normal, I am in the process of installing patch after patch to bring the machine up to snuff. Every time I restart the machine, or most every time, when I try to remote in to the machine I get the Log In window, but then almost immediately I get the message that my remote session was ended. If I physically walk over to the machine and plug in a monitor and keyboard, I see nothing. If I leave the keyboard and monitor in and restart the machine by force, the computer reboots just fine. When windows starts, I get no error message about windows not starting or being shut off unexpectedly. Once I log into the machine physically by the keyboard, I can then remote in to the machine at that point. Very confused. This happens on all 3 machines, these machines have different hardware.

• How do I debug why an OSX key binding stopped working?

  - by nall

  Recently, I've realized that my ^A key binding has stopped working in OSX. My assumption is that some application has registered ^A as a hotkey, but I don't know that for certain. I don't recall installing anything new lately, but it's certainly possible that I did and just forgot. Some other pertinent info: ^A doesn't work in any application -- this isn't just a Terminal.app issue Other control combos (eg: ^E) still work as expected Looking through the Keyboard System Preferences pane shows nothing bound to ^A A reboot doesn't help However, logging into under a freshly made account does cause the issue to go away (i.e.: ^A works for the test account) My StandardKeyBinding.dict has the correct value for ^A Note: I don't have a DefaultKeyBinding.dict in /Library/KeyBindings or ~/Library/KeyBindings Any ideas on how to debug this?

• Windows 7 Incorrect Scaling

  - by Anonymous

  I ran into a problem the second after installing Windows 7 a few months ago, but it only affected a few applications at the time, so I ignored it. Now an increasing number of applications behave the same way and it's annoying. The DPI settings seem to have an issue as can be seen below: The same application should look like this: The DPI is set to 100% (I tried changing it but it had no effect). I think perhaps the Regional / Language settings have something to do with it but I can't turn it off to English only. Any ideas?

• Nvidia driver on Windows 7 causing black screen

  - by inKit

  I have just installed Windows 7 on a desktop machine and for the first time ever have had a really tough time doing so, its normally a nice smooth install. This time I found that the monitor would simply go black after completing the installation. I tried reinstalling about 3 times and this did not help. After much searching I discovered that it was the nvidia drivers that were playing up with win 7, so i booted into safe mode, disabled the device, then rebooted to complete the installation. Windows 7 now works fine as long as the nvidia 9600 gt video card is disabled. The moment I enable it, the system requires a reboot and the screen will go black before even getting to the log in screen. I have tried downloading the latest driver and installing it manually, I have also tried uninstalling the device and allowing windows 7 to install it itself. Nothing seems to work. any clues?

• Will an SSD help prevent laptop overheating?

  - by alex

  My laptop has a severe overheating problem, even though it's quite new (< 6 month). It's still regularly overheating to the point where it shuts down. This usually happens while playing games but sometimes while watching videos or using Skype video calls for a long time. I'm already keeping it mid-air on a cooling tray with 2 external coolers, but that doesn't seem to help. The only other thing I can think of is installing an SSD instead of the current HDD. I've read up that they generate less heat then hard drives, but can it actually make a serious difference to the heat level of the laptop? If there are any other suggestions, please feel free to comment. The laptop is a Toshiba Satellite L650D-11R.

• 2 identical PCs - can I swap a single hard drive between and expect Windows 7/XP to work?

  - by rgvcorley

  I currently work in 2 different locations, traveling between the 2 every few weeks or so. I currently have screens, kb, mouse etc... in both locations, so I just pick up my tower case when I want to move to the other location. However to make moving easier I was thinking of buying 2 tower cases with hot swappable drive bays on the front and installing identical hardware in each one. This would allow me to pull the drives out and just take them with me and plug them into the PC at the other location. Would windows 7 complain? I'm not fussed about buying licenses for both PCs, but would I have any problems with drivers due to the different serial numbers of the components?

• BIOS recognizes HD, but Ubuntu doesn't recognize it as partition

  - by user23792

  Hello, I just stuck in a new 64 GB SSD (literally out of the box) into my Lenovo X61 laptop, replacing an old 5400 RPM 80 GB drive. When I boot the system, my motherboard successfully sees the SATA hard drive. Now I want to install Ubuntu on it. I stick it in the CD drive, bootup the system, and it gets to step 4 (choose partition), but sees no available partitions. Do I need to do something to the hard drive before installing Ubuntu? Many thanks.

• Use Amazon EC2 as a backup server

  - by MikeMurko

  I would like to use Amazon EC2 as an emergency backup database+web server in the event our primary host becomes unavailable. I feel like I wouldn't have trouble setting up a Windows instance, install SQL Server and get the web server up and running (would take a few hours, plus installing various libraries, our source code, etc). My question relates to pricing. If I simply "stop" the instance rather than "terminate" it, does that stop counting "instance-hours"? I would prefer not to terminate the instance and lose all that work I spent setting it up. If I must "terminate" in order to stop the billing - is it possible to make an image of the server after I have set it all up, then save that image somewhere (S3?) Is this something that people do regularly? Ideally this instance would just be waiting in the wings for an issue with our host, but costing us nothing except perhaps data storage costs.

• Cannot login SQL Server after changing machine name

  - by Ucodia

  After installing and setting up new machines in a domain, we decided to rename one of them which had a SQL Server instance installed. So I changed the hostname, everything went fine regarding the domain but now, the server is logging a approximatively 2 SQL Server errors every 5 minutes and I cannot connect to the instance localy or from anywhere within the domain. Here is the error from the event log: SSPI handshake failed with error code 0x8009030c, state 14 while establishing a connection with integrated security; the connection has been closed. Reason: AcceptSecurityContext failed. The Windows error code indicates the cause of failure. The logon attempt failed [CLIENT: x.x.x.x] Concerning the instance, everything is started and restarted without any extra error.

• Install gettext-0.17-1.el5.i386.rpm on CentOS 5.8 i386 gives "/usr/bin/python is needed" error

  - by viji

  I've removed yum by mistake. So, now I'm installing all the dependencies needed by yum manually. One of those is gettext-0.17-1.el5.i386.rpm and when I try to install it gives the following error, error: Failed dependencies: /usr/bin/python is needed by gettext-0.17-1.el5.i386 which is weird since I've installed python 2.6 already in the system. #python -V Python 2.6.8 #which python /usr/local/bin/python So I copied /usr/local/bin/python to /usr/bin/python and even after that I'm getting the same error. Any help is appreciated.

• Prevent specific applications from being run as administrator

  - by Unsigned

  Background Most installation toolkits have the ability to launch, automatically or otherwise, external programs after installation. This is often appears in the installer via such options as "Show readme", or "Start program". Issue The problem is, many of these installers are poorly coded, and do not drop permissions appropriately. For example, starting the application automatically, or opening the application's homepage in the browser, often results in launching the application or browser with the installer's Administrative privileges, or a "High" UAC integrity level! This has the potential to open up security breaches, by opening up the installed application, or a web page (and possibly browser add-ons), that are now running with elevated permissions. (This is the reason I strongly recommend never choosing auto-launch options when installing software.) Question The question is: Is there a way to prevent certain applications (such as a web browser) from ever being launched with Administrative privileges, i.e., an automatic drop-privilege?

• peer to peer disk image transmission

  - by JackWu

  Installing linux/windows through pxe works smoothly for me. But downloading images(especially windows) is a headache. Let alone the time, bandwith usage is horrible. And p2p tech comes to my mind. But I have no clue how it works or where to start. Anyone knows how to setup p2p local network, and applies that on image transmission? Any advice, tutorials or experiences will be great. Thanks in advance.

• Correct usage of Windows Server on network?

  - by Hobart Bosworth

  I have two routers, one with dhcp turned on and the other with it off. this is a functioning home network. Now, I am trying to integrate into it a windows server. Should the windows server be doing the dhcp and dns work? And if so, what will this mean for the existing network? Will I need to reconfigure this? I am currently installing server 2003 onto my server machine. It is connected up to the network on the main router with dhcp. Any words of advice?

• 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.

• Change Firefox theme locally with CSS (without any extension)

  - by Email

  I have some modifications I want to make WITHOUT installing extensions. eg: max width of tab and height of menu, In previous versions you could have it done via: about:config ->browser.tabs.tab.maxWidth Since FF4 it should be done with CSS. Now I searched the default theme: C:\Users\wetcat\AppData\Roaming\Mozilla\Firefox\Profiles\feriz.default and C:\Program Files (x86)\Mozilla Firefox In the second I could find the extension - theme but without any CSS. In the AppData I couldn't find any CSS or theme folder. WHERE is the file to create or alter the CSS?? I'm using Firefox 11.

• How do I audit CD/DVD tray opening events in Windows 7?

  - by MetaHyperBolic

  Since installing Windows 7, the entire office has experienced random CD tray openings, sometimes while we are in the office, sometimes not. On my PC, I have two disc-reading devices, but only the top one ever slides open. I have found nothing in the event logs to that looks appropriate, even going to them right after I saw my own tray slide open all by itself. Although it's not hurting anything (that I can tell), I'd like to know what is going on. To that end, are there any useful ways to audit these events?

• How to install a mmc certificate on Windows?

  - by Alex

  I am not familiar with Windows very much, and I have trouble installing a MMC certificate. I am following this description to use MMC to create a certificate, but I cannot complete the step labeled ' Install or view the certificates under:'. There is nothing unter 'ConsoleRoot' - 'Certificates (Local Computer)' - 'Personal', and when I try to find the certificate I cannot find it. There is another page with nice screenshots, which works until step 9 when I am about to choose the certificate file. I do not know where this file is been created, if at all. How can I create/install/import this certificate? I require this in order to use the powershell Enter-PSSession from a remote machine...
