  • How can I use my laptop's monitor as my PC's ONLY monitor? [closed]

    - by Randell
    Possible Duplicate: Can I use my laptop as a second monitor for my desk computer? My PC's monitor just died and I'm not looking at buying a new monitor anytime soon. So I'm thinking of using my laptop's monitor for it. Both machines are running on Fedora linux. Edit: Both machines are connected to the same wireless network. PC needs to log in before it can connect to the network if I'm not mistaken. Update: This is different from Can I use my laptop as a second monitor for my desk computer? , because that question is asking how to use the laptop screen as the secondary display, not as the only display.

  • Too many connectons to 212.192.255.240

    - by Castor
    Recently, my Internet slowed down drastically. I downloaded a tool to see the TCP/IP connections from my Vista computer. I found out that a lot TCP/IP connections are being connected to 212.192.255.240 through SVCHost. It seems that it is trying to connect to different ports. I think that my computer is being infected with some kind of malware etc. But I am not sure how to get rid of it. I did a little bit of research on this IP but found nothing. Any suggestions are highly apprecitated.

  • Excel 2002 disappears with no error message

    - by i-g
    Excel 2002 closes about 30 seconds after I open it. No further action has to be taken; I open the program, wait a little while, and the window and process just disappears. I'm running Windows XP SP2 with Office 2002 Pro installed. Recently, Outlook 2007 was added to the computer (previously not installed at all.) Word 2002 works fine. Excel 2002 also works fine on another computer with a similar configuration. Things I've already checked for or tried: Verified that no add-ins are enabled. Repairing the installation. Uninstalling and reinstalling. Rename %APPDATA%\Microsoft\Excel I'm guessing that it is trying to load a component that doesn't exist and failing, but I don't know how to proceed. Suggestions welcome. Thank you!

  • Only some motherboards can support faster RAM?

    - by Wesley
    This is a question relating to one of my builds. Here are the specs: ECS P4VXASD2+ V5.0 motherboard Intel P4 Northwood 2.8 GHz (533 MHz FSB, 512 KB L2) 2x 1GB PC3200 DDR RAM Maxtor 300GB IDE HDD 16 MB NVIDIA TNT2 Pro AGP OKIA 300W ATX PSU Gigabyte 52x CD-ROM The issue right now is that I'm trying to install Windows XP from the CD drive but the computer randomly restarts partway through installation. My other build was BSODing due to RAM latency errors. This ECS board manual states that memory modules "up to 333 MHz" (i.e. PC2700) is supported. However, I am running PC3200 modules, which is clearly faster than PC2700. Would this be causing the computer from randomly restarting? EDIT 1: I also wanted to mention that my Emachines T2482 is actually running 2x 512MB PC3200 DDR RAM when it should only be supporting PC1600 and PC2100 DDR RAM. Yet there are no issues with it.

  • Changing Word mail merge data source locations in bulk?

    - by Daft Viking
    I've just moved a number of Word mail merge files, and a number of Excel spreadsheets that are the data sources for the mail merges, from a Windows XP computer to a Windows 7 computer, and now all the paths for the merge sources are incorrect (used to be c:\documents and settings\user\my documents.... now c:\users\documents....). While I can correct the path of the data source in each file individually, I was hoping that there would be some way of updating the files in bulk, as there are a relatively large number of them. Word 2007 is what is being used, but the documents are all in the previous DOC format (not DOCX).

  • I am afraid that my University is not going to teach me enough information [closed]

    - by Muhklayne
    I attend a University and am a Computer Science major. I have barely entered into the major, as I am a sophomore. However, the coursework I am doing is extremely easy already and I feel as though this degree is going to lead me to a path of knowledge without knowing how to bring it all together. Therefore, I am coming to you to ask where I should begin learning on my own! I am willing to dedicate hours upon hours of learning to code outside of class, as it is truly my passion. I will begin by completing all work on http://www.codecademy.com, however I feel this will not be enough either. I would love to learn to integrate visual languages for video games such as NXA and C# combining it with C++ (as I understand video games can be created in this manner). I would also like to look into LUA and Python scripting. I am asking for advice as to where I should begin my personal studies of learning to program, as with my research it has become quite apparent that simply attaining a degree in Computer Science is quite frankly not enough. Thank you for your time!

  • Port forwarding not working?

    - by rphello101
    I'm trying to set up an Apache Server to be accessed publicly. I'm using a Netgear R4500 router hooked up to a Motorola SB6121 modem. I can access my server on my computer by typing in my IP address. After following the instructions to forward port 80 so I can access the server from other computers, it does not work (see image). I get "This webpage is not available". I am forwarding to the IP address of my computer. Using this Network Port Scanner Tool, it says "80/tcp filtered http", which, as I understand it, means forwarding did not work correctly. In my Apache httpd file, I have: ServerName 192.168.1.13:80 and Listen 192.168.1.13:80 Anyone know what's wrong or have something I can try? click to enlarge

  • Folder Redirection won't load on Windows 7 Machine in Windows 2008 R2 Network

    - by leeand00
    Okay so redirected profiles don't load exactly, but the computer is joined to the network and it won't display any of the users files on their desktop that are in their redirected profile. I know this because we have a Terminal Server and when the user logs in there, her files appear. I checked the users' profile in Active Directory Users and Computers and compared it with a working users profile. When that didn't turn up any differences, I looked at her computer and found that on the Dial-in tab the Network Access Permission wasn't set to Control access through NPS Network Policy like it was on the other machines on the network; so I selected it, ran gpupdate /force on her machine and rebooted. This did not fix the issue. Is there anything else that could be preventing the redirected files on the users desktop from showing up when the user logs in?

  • DIY Halloween Decoration Uses Simple Silohuettes

    - by Jason Fitzpatrick
    While many of the Halloween decorating tricks we’ve shared over the years involve lots of wire, LEDs, and electronic guts, this one is thoroughly analog (and easy to put together). A simple set of silhouettes can cheaply and quickly transform the front of your house. Courtesy of Matt over at GeekDad, the transformation is easy to pull off. He explains: It’s really just about as simple as you could hope for. The materials needed are: black posterboard or black-painted cardboard; colored cellophane or tissue paper; and tape. The only tools needed are: measuring tape; some sort of drawing implement — chalk works really well; and scissors and/or X-Acto knife. And while you need some drawing talent, the scale is big enough and the need for precision little enough that you don’t need that much. For a more thorough rundown of the steps hit up the link below or hit up Google Images to find some monster silhouette inspiration.

  • Getting the PC speaker to beep

    - by broiyan
    There has been much written on getting the beep sound from Ubuntu releases over the years. Example: fixing the beep My needs are slightly different in that I do not want to ensure sound card beeps are functioning. Instead, I want PC speaker beeps, the kind produced by the original built-in speaker because I believe they will produce less CPU load. I have confirmed that my computer has the PC speaker by unplugging the external speakers and shutting down Ubuntu. At some point in the shutdown and restart process a beep is heard even though the external speakers have no power. I have tried the following: In /etc/modprobe.d/blacklist.conf, turn these lines into comments: #blacklist snd_pcsp #blacklist pcspkr In .bashrc /usr/bin/xset b on /usr/bin/xset b 100 Enable in the gnome terminal: Edit Profile Prefs General Terminal Bell Ensure no "mute" selections in: System Prefs Sound various tabs (uncheck them all). Select "Enable window and button sounds" in: System Prefs Sound Sound Effects In gconf-editor desktop gnome sound, select the three sound check boxes. In gconf-editor apps metacity general select the audible bell check box. Still I get no PC speaker beeps when I send code 7 to the console via my Java program or use echo -e '\a' on the bash command line. What else should I try? Update Since my goal is to minimize load on the CPU, here is a comparison of elapsed times. Each test is for 100,000 iterations. Each variant was performed three times so three results are presented for each. printwriter.format("%c", 7); // 1.3 seconds, 1.5 seconds, 1.5 seconds Toolkit.getDefaultToolkit().beep(); // 0.8 seconds, 0.3 seconds, 0.5 seconds try { Runtime.getRuntime().exec("beep"); } catch (IOException e) { } // 10.3 seconds, 16.3 seconds, 11.4 seconds These runs were done inside Eclipse so multiply by some value less than 1 for standalone execution. Unfortunately, Toolkit's beep is silent on my computer and so is code 7. The beep utility works but has the most cost.

  • Full Uninstall winvnc.exe

    - by thenickperson
    This computer (Windows 7) has not been able to run Windows Aero after I installed some VNC software, UltraVNC and TightVNC. I want to get Aero back, and Microsoft Fix It tells me that it can't be turned on because of mirror drivers (this edition includes Aero, and I had it working well before), which I managed to learn can come from winvnc.exe, which is installed by both programs. I would like to uninstall winvnc.exe and the service from this computer. I messed with the command line a little (I know, I aws being careful), but I couldn't get anywhere, I'm a total beginner with the command line. Can someone please help me remove the exe file and the service, so the mirror drivers are disabled and I can use Aero again? I don't need the VNC servers (I couldn't get them to work anyway), but if keeping the clients is possible that would be nice.

  • Kids and programming: ScratchKara

    - by Mike Pagel
    Ever now and then I kept wondering how to share with my kids the excitement of creating something with your computer. Of course, today this is a bit more difficult, as they have seen 3D animation games and well-edited websites. I guess that's why they weren't all that hyped when I found my first computer model at our local recycling facilities (an 8-bit Laser VZ-200 with rubber keys). When I finally got it up and running with an old analog TV set they finally asked whether we could play soccer on it. Needless to say that my showing them how it remembers some BASIC commands and lists and executes them did not make any impression. So the question is for real: How do you get today's kids excited about programming? And just recently I looked again for environments that allow even young kids (mine are 7 and 9 years old now) to do something and have fun. Obviously any real, text-oriented programming language wouldn't work well. To cut it short: Something really nice was built by University of Oldenburg: ScratchKara. It is the perfect mixture of Kara, a simulation of a little ladybug and Scratch, an authoring environment from MIT. ScratchKara allows kids to initially simply explore how the bug moves and turns by pressing the action buttons, then move towards sequencing commands through drag & drop, and eventually end up building algorithms with procedures and functions. Even through it is built for kids and beginners, the environment comes with debugging and refactoring, which I found more than amazing. My kids love it and I have to admit I keep thinking about how to solve a bit more advanced problems with this language, which does not allow you to store any state information (other than your call stack). Yes, I am hooked, too... Once the language is understood you can then move to one of the original Kara versions, where you can define the bug's behavior through finite statemachines, Turing tables, Java and other textual languages. And from there, anything is possible.

  • Temp profile used when User logs in

    - by TJ
    One of my users logged into his computer, Windows XP, last night only to be meet with an error message that it could not load his profile and he will be logged in using a temporary profile. Typically when this happens I shut the machine down and restart and the correct profile will load when they log in again. Not this time. In the user profile options under computer-properties-Advanced-user profiles it show that there are three profiles with his name. Two are the exact same size with the same modified date (5/5/10) and the other is what I would expect size wise for a new profile with a modified date of today. What are my options to restore his profile?

  • How can I get a data usage/access log for an external hard-drive?

    - by Vittorio Vittori
    Hello, I'm working in an office with many people and sometimes I leave my external hard drive with my personal data inside. I would to know if there is some way to see if my hard disk was used during my absence. I'm not the computer administrator, so I can't use exclusive file permissions and I would really like to know hard disk is opened from another computer. I am using a Mac. Does exist some other way to protect personal data on usb device like an hard-drive? If yes can you write some link to possible guides? I hope there is some ploy!!

  • What do encrypted files' data look like?

    - by Frost Shadow
    I know there are a lot of encryption programs available, that I would guess use different methods for encryption, and thus have different types of output files (.fve .tc .cha .dmg (bitlocker, truecrypt, challenger, ect.)), but if someone didn't know what the file was and just looked at the data, what would it look like? Does it just look like random bits, or can you still pick out a pattern? If it does look random, how is it if I moved the encrypted file to another computer, the other computer can tell it's a file, and is able to decrypt it (how would it even know where to start or stop, if it all looked random)? Also, how is the structure affected by encrypting files twice, using the same method, or a different one? Thanks for any help, and if you know any books or site about encryption for complete idiots, I'd appreciate it!

  • Failure to Boot Windows 7 after Ubuntu install

    - by Mike
    My computer is a (brand new) PC notebook, without a CD drive running Windows 7. I followed this page to install from USB: https://help.ubuntu.com/community/Installation/FromUSBStickQuick The installation went well and i am using Ubuntu now (v. 12.04 i believe) I want to be able to dual boot Ubuntu and Win7 The problem is that the disc partitioning during the Linux install caused a problem with Windows, caused some problem with windows, and windows can no longer boot when i choose it at the GNU GRUB screen. When i restart my computer i can successfully boot Linux, but not Windows 7. At the GRUB screen - if i run Win7 normally, it freezes, shows a blue screen, and returns back to GRUB - if i run Win7 recovery, i dont know how to access the files that i need in order to run windows again, so nothing helpful happens. Can you please tell me what i would need to do(or link a guide) in order to run Windows again. (Windows and Linux is preferable, but if thats impossible going back to only Windows will help too) Im guessing the easiest thing to do is just to reinstall both OS, or is there anyway to undo the partition i made during the install? Thanks

  • crippling repeating "pciehp card not present" notifications

    - by Nanne
    When using ubuntu (12.04, both installed and on a live usb) I get a lot of these messages: pciehp 0000:00:1c.5:pcie04: Card not present on Slot(37) pciehp 0000:00:1c.5:pcie04: Card present on Slot(37) And with a lot I mean about 20 per second. This has a crippling effect, and I would like to get rid of it :) The computer is a packard bell easynote BG48-U-100 DC. I tip I picked up from some fedora/redhat error here was to look at lspci -vnn. I have pasted the part about "00:1c.5" here: http://pastebin.com/0sfsiqW2 For what good it may do, here is the lsmod of my machine: http://pastebin.com/DQZy1kAL From that first pastebin I think to conclude that it has to do with the module shpchp, which seems to me (aka: google) to have something to do with ACPI. That's as far as I've come in disecting this. Can anyone help me along further? What can I do, check etc? I did see this topic but my intentions are not to surpress the error message: I know how to do this (from that topic ;) ), but I'm looking for a real sollution. Finding the problem on the internet does suspect me to believe it is neither an ubuntu specific nor a packard-bell specific problem.If you google the problem it seems that is present on several other distribution/hardware combo's as well, and it looks like the advice is to remove one of the drivers? I have no clue as to which driver I should look at and and what would be the effect of just removing it. I have seen this topic which is old-ish, but describes my problem and is about a similar computer. The solution in this topic was to compile a new kernel using a spanish guide, which seems a bit extreme to me, so I'm kinda hoping for a better solution than that.

  • Problems with Ubuntu and AMD A10-4655M APU

    - by Robert Hanks
    I have a new HP Sleekbook 6z with AMD A10-4655M APU. I tried installing Ubuntu with wubi--the first attempt ended up with a 'AMD unsupported hardware' watermark that I wasn't able to remove (the appeared when I tried to update the drivers as Ubuntu suggested) On the second attempted install Ubuntu installed (I stayed away from the suggested drivers) but the performance was extremely poor----as in Windows Vista poor. I am not sure what the solution is--if I need to wait until there is a kernel update with Ubuntu or if there are other solutions--I realise this is a new APU for the market. I would love to have Ubuntu 12.04 up and running--Windows 7 does very well with this new processor so Ubuntu should, well, be lightening speed. The trial on the Sleekbook with Ubuntu 12.10 Alpha 2 release was a complete failure. I created a bootable USB. By using either the 'Try Ubuntu' or 'Install Ubuntu' options resulted in the usual purple Ubuntu splash screen, followed by nothing...as in a black screen without any hint of life. Interestingly one can hear the Ubuntu intro sound. In case you are wondering, this same USB was trialed subsequently on another computer with and Intel Atom Processor. Worked flawlessly. Lastly the second trial on the Sleekbook resulted in the same results as the first paragraph. Perhaps 12.10 Beta will overcome this issue, or the finalised 12.10 release in October. I don't have the expertise to know what the cause of the behaviour is-the issue could be something else entirely. Sadly, the Windows 7 performance is very good with this processor-very similar and in some instances better to the 2nd generation Intel i5 based computer I use at my workplace. Whatever the cause is for the performance with Ubuntu 12.04 or 12.10 Alpha 2, the situation doesn't bode well for Ubuntu. Ubuntu aside, the HP Sleekbook is a good performer for the price. I am certain once the Ubuntu issue is worked on and solutions arise, the Ubuntu performance will probably be better than ever.

  • Windows VPN not authenticating from ADSL to Wireless link

    - by deanvz
    I have a normal windows VPN on a computer connecting to a 196.201.x.x/24 IP. If this VPN tries to connect from any address in the 41.x.x.x range it cant get there. The server is a normal windows 2008 server, running exchange with a PPPoE IP natted to a public IP on the public gateway of the wireless network as the server is on site and its connectivity is derived from Mikrotik RB's. The computer on the 41 range can traceroute and ping the server, but the VPN does not authenticate. When on the network or any other, the VPN works fine. Is there something that could be configured on the VPN client? All firewall settings of a standard ADSL router have been checked and found to block only ICMP's. Is this a VPN configuration problem or a network issue?

  • How to switch to a generic kernel in a headless Ubuntu Server 12.04?

    - by chmike
    I just got a dedicated server with Ubuntu 12.04 installed with a custom compiled kernel. Since I would like to install VirtualBox and this custom kernel doesn't support dynamic module loading (for security) I need to change the kernel. I'm running some Ubuntu servers for years but never palyed with grub and a headless computer. When the command update-grub is run it shows the different kernel it finds. Here is what I see Generating grub.cfg ... Found linux image: /boot/bzImage-3.2.13-xxxx-grs-ipv6-64 Found linux image: /boot/vmlinuz-3.2.0-34-generic Found initrd image: /boot/initrd.img-3.2.0-34-generic No volume groups found done The first one is the active one as seen with uname -r. To me it looks like the second kernel is the one I should use. But I don't know how to configure grub2 to use it. The computer is also configured with a software RAID using mdadm I guess. Never used that before. I don't know if playing with the grub of changing kernel could brake this. What must I do to set the generic kernel as the default one so that I can get VirtualBox running.

  • Looking for Fiddler2 help. connection to gateway refused...just got rid of a virus?

    - by john mackey
    I use Fiddler2 for facebook game items, and it's been a great success. I accessed a website to download some dat files I needed. I think it was eshare, ziddu or megaupload, one of those. Anyway, even before the rar file had downloaded, I got this weird green shield in the bottom right hand corner of my computer. It said a Trojan was trying to access my computer, or something to that extent. It prompted me to click the shield to begin anti-virus scanning. It turns out this rogue program is called Antivirus System Pro and is pretty hard to get rid of. After discovering the rogue program, I tried using Fiddler and got the following error: [Fiddler] Connection to Gateway failed. Exception Text: No connection could be made because the target machine actively refused it 127.0.0.1:5555 I ended up purchasing SpyDoctor + Antivirus, which I'm told is designed specifically for getting rid of these types of programs. Anyway, I did a quick-scan last night with spydoctor and malware bytes. Malware picked up 2 files, and Spydoctor found 4. Most were insignificant, but it did find a worm called Worm.Alcra.F, which was labeled high-priority. I don’t know if that’s the Anti-Virus Pro or not, but SpyDoctor said it got rid of all of those successfully. I tried to run Fiddler again before leaving home, but was still getting the "gateway failed" error. Im using the newest version of firefox. When I initially set up the Fiddler 2.2.8.6, I couldn’t get it to run at first, so I found this faq on the internet that said I needed to go through ToolsOptionsSettings and set up an HTTP Proxy to 127.0.0.1 and my Port to 8888. Once I set that up and downloaded this fiddler helper as a firefox add-on, it worked fine. When I turn on fiddler, it automatically takes my proxy setting from no proxy (default) to the 127.0.0.1 with Port 8888 set up. It worked fine until my computer detected this virus. Anyway, hopefully I've given you sufficient information to offer me your best advice here. Like I said, Spydoctor says the bad stuff is gone, so maybe the rogue program made some type of change in my fiddler that I could just reset or uncheck or something like that? Or will I need to completely remove fiddler and those dat files and rar files I downloaded? Any help would be greatly appreciated. Thanks for your time.
