• ATI Radeon HD 5970 Display numbering issues

  - by Arindam Sen

  I have 2 computers on which i have ATI Radeon HD 5970 graphics card installed. There is 1 VGA out and 1 DVI out in it. When I connect my VGA out to a monitor on my 1st computer, it shows it as display 1 and when I connect my DVI out to a monitor it show it as display 2 (I am using extended display). When I do the same thing on my 2nd computer it shows just the opposite. The VGA out shows as display 2 and the DVI out shows as display 1. Is it a problem with the drivers or the hardware? (because the graphics card on both is exactly the same)

• screen does not wake up after suspend/ brightness will not adjust

  - by Nathan

  My computer is one of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16834230467 Asus Zenbook UX32A-DB51 Just bought it yesterday. Set to "suspend" when I close the lid, but when I open it up again I just get a black screen. Pressing the power button doesn't work, not does clicking the mouse or any key combination. The same is true if I leave the computer until it suspends. Black screen, no response, have to reboot. I also can't seem to adjust the brightness. I put "brightness up" and "brightness down" function keys in, and when I push them it shows the brightness level as going up and down on the meter, but the screen does not actually become more or less bright. I am totally new to all of this. Please tell me what additional information you need to help me and where I can find it. Thanks! Edit: Tried the following: sudo gedit /etc/default/grub Change the line GRUB_CMDLINE_LINUX="" into GRUB_CMDLINE_LINUX="acpi_osi=Linux" sudo update-grub Restart your linux And "acpi_backlight=vendor" both to no avail.

• How to lock the c prompt?

  - by allindal

  Is there anyway to lock the command prompt? I need my computer to require a password to use the command prompt. I lock the workstation occasionally but sometimes I forget and if I could just prevent my roommate from doing the "c: net user user *" to change my password it would be great. I do not want to have to use the rundll.32 user command with script to automatically lock the computer. Just a way to lock the c prompt. Sorry for not saying this earlier, I'm running a vista 32bit Asus gene II motherboard with a core i7 CPU

• Lagging digital tv over ethernet

  - by Steve

  I have a HD Home Run TV over ethernet device, which connects the aerial to my router, and from there the router connects to my PC over about 15m of 100Mbps ethernet cable. The TV output lags every second. It does not do so for a computer much closer to the router. It is odd to me that the network rate is around 7Mbps on a 100Mbps cable. I am not downloading or streaming anything else on the affected computer. Is this lag caused by the speed of the cable, the length of the cable, or interference on the cable? I am considering swapping the ethernet cable with shielded ethernet cable.

• Firefox can't establish a connection to the server at www.google.com

  - by Tom

  My home page in Firefox [v4.0] and Internet Explorer [v9.0.8112.16421, Update Versions RTM (KB982861)] is currently set to Google but when I depress the quick start icon to start up either browser, I am getting the following immediate results: Unable to connect (In Firefox) Firefox can't establish a connection to the server at www.google.com. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer's network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web. Internet Explorer cannot display the webpage What you can try: Diagnose Connection Problems More information This problem can be caused by a variety of issues, including: Internet connectivity has been lost. The website is temporarily unavailable. The Domain Name Server (DNS) is not reachable. The Domain Name Server (DNS) does not have a listing for the website's domain. There might be a typing error in the address. If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section. For offline users You can still view subscribed feeds and some recently viewed webpages. To view subscribed feeds: Click the Favorites button , click Feeds, and then click the feed you want to view. To view recently visited webpages (might not work on all pages): Press Alt, click File, and then click Work Offline. Click the Favorites button, click History, and then click the page you want to view. Thankfully, I am able to use one browser that I have installed on my computer (Mathon v3.0.20.5000) to search online for technical assistance in this matter. I have seen several WinSock error issues mentioned; but, they are pointing to Windows XP and I am using Windows 7 Pro and remain uncertain whether anything identified as a fix for one OS will work in another. Things I've tried: HiJackThis Complete scan with Avira AntiVirus Premium. What am I overlooking? What should I do to address this problem?

• How to get rid of NAT in a LAN?

  - by Alberto

  Currently the LAN I manage is organized as follows: internal network (192.168.1.0) which uses a Linux server as a gateway (internal address on interface br0 192.168.1.1, external address on interface br1 10.0.0.2) through NAT; then the 10.0.0.0 network has another gateway (10.0.0.1) which through another NAT connects the whole thing to the internet. What I would like to achieve is to configure the Linux server so that the first layer of NAT is no more necessary, so that for example a computer in the 10.0.0.0 network can ping every computer in the 192.168.1.0 network. I deleted this iptables rule: iptables -t nat -A POSTROUTING -o br1 -j SNAT --to-source 10.0.0.2, but of course now computers on 192.168.1.0 cannot reach the internet; ip forwarding is of course enabled. What's missing here? Thanks

• How can I set my resolution to 1280x1024 on an Acer Aspire Revo 3700?

  - by torbengb

  I've just set up a new nettop computer (Acer Aspire Revo 3700: CPU:Atom D525, GPU:Nvidia ION2). I've just made a clean install of Ubuntu 10.10 using the standard USB pendrive method. Almost everything works OK, but the graphics are not OK: the recommended Nvidia driver is activated but the monitor is not detected, so the resolution is wrong. How can I make Ubuntu detect my monitor? How can I get the proper resolution (1280x1024) in Ubuntu? I know that my monitor is not a CRT but an LCD: it's a BenQ, model T905, with 1280x1024 resolution at 60Hz, connected via a normal VGA cable. DVI or HDMI is not an option. When I go to SystemPrefsMonitors, I get: It appears that your graphics driver does not support the necessary extensions to use this tool. Do you want to use your graphics driver vendor's tool instead? YES NO If I say NO then I get a window: or for YES I get this: In both cases I don't see that I can fix this problem. The main reason for getting this new computer was that I was sick of having graphics problems on the old one with a very ugly solution that didn't give me hardware support - but at least I got the resultion. Why is this so difficult... sigh!

• Assisting a user using VNC

  - by wizlog

  I'm trying to help a friend with their computer remotely. He has a version of VNC, I'm not sure which one, so I downloaded and installed the VNC Viewer and Listening Viewer. I ask my friend for his IP address and port number, and he tells me that every time he's used it, the person giving him assistance (remotely controlling his computer) gave him some kind of number. I should note that my friend is not tech savy, and it may have been an IP address, but I'm not sure. What kind of number would the user be looking for? Does this indicate his version of VNC, Does that even matter? I am completly forign to VNC and don't know where to begin looking for an answer myself, and (for whatever reason) I can't ask my friend to figure out what version of VNC he is using.

• Is it a must to focus on one specific IT subject to be succesful?

  - by Ahmet Yildirim

  Lately I'm deeply disturbed by the thought that I'm still not devoted to one specific IT subject after so many years of doing it as a hobby. I've been in so many different IT related hobbies since I was 12. I have spent 8 years and now I'm 20 and just finished freshman year at Computer Eng. Just to summarize the variety: 3D Game Dev. and Modelling (Acknex, Irrlicht , OpenGL, GLES, 3DSMAX) Mobile App.Dev (Symbian, Maemo, Android) Electronis (Arduino) Web.Dev. (PHP, MYSQL, Javascript, Jquery, RaphaelJS, Canvas, Flash etc.) Computer Vision (OpenCV) I need to start making money. But I'm having problem to pick the correct IT business to do so. Is it a problem to have interest in so many different IT subjects?(in business world) I'm having a lot of fun by doing all those stuff from time to time. Other than making money I also noticed that having so many different interests is lowering my productivity. But I'm still having difficulty to pick one. I'm feeling close to all those subjects (time to time).

• RAID 1 not performing as expected

  - by Faken

  I recently bought a new 320Gb hard drive for my computer to set up RAID 1 on it for some added security. Installation went as smooth as could possibly be (plug in power, plug in data cable, start up computer, Intel software recognized new drive, right click create RAID 1, done!). However, for some inexplicable reason, I seem to have strange test results when using BENCH32. On my old configuration, a single 7200 rpm drive, I achieved about 60 MB/s write and 70 MB/s read. With a new RAID 1 configuration, I would expect the write to be slightly diminished but read to be significantly improved (though not exactly double speed). However, with the new configuration, I am getting 90 MB/s write and only about 80 MB/s read. I should NOT be getting improved write performance, especially NOT better than read! What's going on? My system setup is: q6600 2.4ghz CPU 4Gb DDR2 667mhz RAM on board Intel ICH9R "RAID chip" 2x Seagate 7200 RPM 320GB drives in RAID 1 Widows 7 home premium 64-bit

• Why would http & https be blocked, even in safe mode with firewall disabled?

  - by Cogwheel

  I have a windows 7 machine (dell studio xps). Everything on it seems to be in working order. The network device says it has internet connectivity, and indeed I can ping websites, transfer files via ftp, connect to vpns and remote desktop, but the web won't work. I've disabled the windows firewall and still no go. There are no other firewalls installed. The computer came with a trial of norton 360 so I also used the norton removal tool (which solved a similar problem on another computer for me previously). Any thoughts?

• Enable multiple audio output on Windows 7

  - by patrick

  For Windows 7, 64 bit: I have a digital SPDIF output to my stereo, which controls speakers in other rooms. I also have a set of speakers connected to the regular audio jack at the computer. This allows me to send music to the kitchen while my child plays games on the computer. Works great. Except when I'm playing games and still want to listen to music. ;-D I know I can manually switch WMP to play through the speakers instead of SPDIF, but I was wondering if there's any way to enable simultaneous audio out in Windows 7? Virtual Audio Card is a non-starter because I'm running 64 bits and the VAC driver isn't signed.

• Cannot open any web page, but MSN Messenger works

  - by Steven

  I use my computer behind a router. My MSN program can connect to the Internet, but I can not open any web site with my web browser. It seems that this problem is related to DNS because when I input an IP address directly in the address bar of my web browser, the web page can be displayed. However, I don't know how to fix this problem. I choose Google Public DNS server on my computer, this problem still exists. My OS is windows XP. How to fix this problem? Any ideas?

• GRUB2 not working after installing xubuntu 14.04

  - by h3bm

  I have a vaio laptop and it used to have installed windows 8 and Xubuntu 13.04 in dual boot, everything was working fine. I decided to update my version of xubuntu 14.04 LTS mainly because the support for 13.04 is finished and LTS version have 3 years of support. What I did was to format the partition where xubuntu 13.04 was installed and install 14.04 in that formated partition. When I restarted my computer willing to start using my new system I got the following message: error: symbol 'grub_term_highlight_color' not found and I was not able to enter any OS. I tried boot-repair from live USB more than two times and it did not fix the problem. I tried to enter to my computer using super GRUB2 disk, however it does not apperar to work with UEFI active (besides super grub2 disk says it can) I only get the message "no operating system found". If I boot super grub2 disk with UEFI disabled, super grub2 disk can not detect any OS,I also tried Rescatux distro, however, as of super grub2 disk, rescatux cannot enter when UEFI is active. I tried boot-repair with the option of "restore EFI backups", after that I was able to boot on windows, but no grub menu appeared. I ran boot-repair again with no improving results Here is the last Bootinfo report I got: http://paste.ubuntu.com/7609801/ Do you have any idea of what is happening? I really appreciate your help, Best regards,

• Ubuntu Slow - What architecture does the Windows Installer install?

  - by Benjamin Yep

  I feel absolutely limited by using Windows, and I need to switch to a Unix environment. I once installed Red Hat on my lappie (screen + external monitor setup; 4GB ram; x64; runs fast) and it worked fine, but I saw that the computer cluster that is the birthplace of my unix knowledge switched to Ubuntu, so naturally I follow. To the point. When I installed Ubuntu onto my machine via the Windows Installer, it ran quite slow. Opening Firefox takes about 8-9 seconds, it freezes up often, unable to handle its own background processes. I saw in a thread that, perhaps, it is running slow because the Windows Installer is installing an x64 version. Of course, my computer has had no performance issues in the past(except that time with the trojans but you know, know one is perfect ;) ) Anyways, I uninstalled Ubuntu, freeing up the max allocated memory it took up, and continue to be sad, trapped in my MS world with only a buggy Cygwin, any assistance is greatly appreciated! :) Thanks ~Ben

• Windows 7: Server disappearing from Network window

  - by David Veeneman

  I am running a small (three computer) network on a Windows Server 2003 domain. All of the computers were just upgraded to Windows 7. Since the upgrade, the icon for the domain server periodically disappears from the Network window on all three computers. It doesn't happen at the same time on all computers--the icon typically disappears from one machine, but not the others. And it's not always the same computer. The network connection is still there--I can type \\myserver and get to the network shares. It's simply the icon that's disappearing. Has this happened to anyone else? Any suggestions for a fix? Thanks in advance.

• Windows 7 freezing unexpectedly

  - by Thomas Deutsch

  I have a Windows 7 computer here, which is freezing between 2 times a day and 1 time every second day. I see no problem, no special drivers, no special Apps are open, no encryption or something like that. Apps usually open then are Firefox, Thunderbird, Eclipse and maybe Office.

Eventlog shows me an kernel error saying it has been unexpected rebooted due to an fatal error, but no statement about what kind of error happended. Anyone an idea what it can be? Chkdisk should be ok (currently, I run it a second time).

• Apply Group Policy to Remote Desktop Services users but not when they log on to their local system

  - by Kevin Murray

  Running Windows Server 2008 Service Pack 2 with Remote Desktop Services role. I want to hide the servers drives using a GPO, but not the users local drives when they are logged on to their local system. Using a GPO, I went to "User Configuration - Policies - Administrative Template - Windows Components - Windows Explorer" and enabled "Hide these specified drives in My Computer" and "Prevent access to drives from My Computer" and in both used "Restrict all drives". Then under "Security Filtering" for the GPO, I restricted it to the system running Remote Desktop Services and the specific users who will be using RDS. I then applied the GPO to our domain and it worked a little too well. Not only was I successful in getting the GPO to work for RDS users, but it also affected those same users at their local systems as well. I've tried everything I can think of, but can't figure out how to apply this just to the RDS but not at their local system. What am I missing?

• 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?

• What are the options for retraining formally as a software engineer?

  - by Matt Harrison

  I'm a self-taught programmer. I have a good undergraduate degree in Architecture (building, not software). I was always a science/maths kid and got consistency good grades in these subjects. However I became indecisive at undergraduate level and switched between Physics, Chemistry, Art and finally stuck with Architecture mainly out of the desperate need to finish any degree. As soon as I graduated, I ditched architecture and started writing code again professionally. I've been a programmer now for 3 years and I've progressed very quickly. I'm ambitious and I want to work for the top companies in this field at some point and I've realised I need a Computer Science education to be taken seriously (based on job ads for the big tech firms). I've applied for a few MSc programs in Computer Science but they've all rejected me because of my BA. It's just not an option for me to quit my job and go back and do another 3 year undergraduate degree in CS. I know I can study at this level because I've read most of the books on the reading lists for CS courses in the UK that I can find and I have this knowledge now, it's just I can't prove it on an application form. What options are available to me?

• 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.

• Using Folder Redirection GPO and Offline Files and Folders

  - by user132844

  I want to use Folder Redirection to redirect user's My Documents to a network share. First question is: What is best practices for mapping the drive? Should I use the profile tab in AD with the %username% variable, or a net use logon script, or something else? Second question is: How do I deal with laptops and syncing the network with the local storage? I want to have 2-way syncing so if they manually map their networked home drive and edit it from a different computer, it will sync the newer version to their My Documents folder the next time they connect their normal work computer. I also want to be sure that if they edit a file offline on their laptop while away from the office, that the network version syncs the changes the next time they connect that laptop. Please advise best practices for this scenario in a 2008 R2/Win7 environment. I am also interested in Mac clients for this environment, and while I am very Mac savvy, I would like to hear what others consider to be best practices for Mac network homedirs in a Win environment.
