  • Dual Monitor Setup with Ati Radeon Hd 5700 results in unusabledesktop win7

    - by NorthPole
    I have an ATI Radeon HD 5700 card which i've been using under fully updated windows 7 with its latest drivers. My monitor is a 2004 NEC LCD1703M which despite being pretty old runs fine. A friend gave me an IIYAMA ProLite E1900WS monitor (2009 or 20010 ). Both monitors are vga only. I've been using a DLDVI to VGA adapter to connect my old monitor and tested the same adapter to the new monitor and it worked fine. So I bought an HDMI to vga adapter with the purpose of having a dual monitor setup. But when both screens are connected to the card the following problem occurs: The monitor connected to the hdmi port cycles between sleep and a black screen while the other shows the operating system for about two seconds before getting black for another two seconds. I can "use" the computer (move the mouse,click,type e.t.c.) while this happens but its not something pleasant. I tried reinstalling the driver, booting with both screens connected (in which case the powerup messages and the bios are mirrored in both screens until I get to the login screen where everything falls apart) Funny thing is, everything works if I disconnect the ATI graphics card and use the onboard intel one. So, any suggestions as to what might be the problem and how I can fix it?

  • Linux Mint 13 is not booting on dual boot computer

    - by Brian
    thanks in advance for your time. I have 2 hard drives in my computer a 300 GB drive which is my primary drive for windows 7 and a 1.5 TB drive that I'd used for storage. When I got it I partitioned 500 GB for use in Linux. So, I created a bootable USB and clicked the "Install by Current Operating System" option from Mint. It installed it to the free 500 GB like I'd hoped it would. Now, I can't get it to boot though. I've tried using EasyBCD to create the boot entry and it hangs on a black screen. Thanks. EDIT @ Ryhuk It presents a menu with two options 1) Windows and 2) Mint. This was a menu I created with easyBCD. When I select option 1 it boots to windows fine. When I select option 2 it hangs on a black screen with just a white bar flashing (Can't remember what its called, it marks the current cursor location on a text field) and won't respond to any key presses but alt ctrl del.

  • Looking for QNX compatible server hardware

    - by Sergey Sobolev
    Can you help me to find compatible modern server for QNX, please? This is quite rare OS, so most of the hardware vendors do not have compatibility information. It would be very helpful to me if you can do the following: Download iso http://www.qnx.com/download/download/19602/qnxsdp-6.4.1-x86-200905201802-nto.iso burn to cd Start from cd press F2 - try from CD start Utilities/Terminal run sloginfo /tmp/sloginfo.log; get_hw_info; pci -vvv /tmp/pci-vvv.log send logs from /tmp/ to [email protected] with system model/build I will summarize results afterwards and post them here. I'm especially interested in Fujitsu RX100 S5 as it looks like one of the most compatible servers with frontally accessible HDDs.

  • IBM Thinkpad 240 - Best way to boot from floppy to USB - Best Linux for 300 MHz 128 MB RAM 800x600 s

    - by zillion
    Mostly I still have that old 'ultraportable' laptop that is mostly like a pre-netbook era laptop and a friend and programmer needs a computer because the one he was using just broke and he has to wait until the new one arrive in 4-6 weeks ... This laptop has no LAN connection and CD-ROM so be prepared for a real challenge! All hardware is well supported on Windows XP (included drivers on the Windows XP CD) and on Linux out-of-the-box (but the screen need a special configuration.) Mostly any Linux that will work well with Skype (USB or regular headset), any MSN client and a text writer for code will do. What I have tested so far: Slitaz 2 don't boot because the floppy of GRUB4DOS don't see the USB drive (fully working and tested on my regular laptop), Damn Small Linux was working but was needing a special screen configuration that I don't remember (in the boot options of the floppy) and now I'm thinking about Puppy Linux that is seen to work totally out of the box with it but I will need an old Puppy version (1 or 2 I think) and the Wakepup floppy ... If you got some ideas to help or to try I'm open!

  • How to use WeirdX applet instead of X11 for remote connections in Mac OS X?

    - by penyuan
    When I am away, I've got an Apple PowerBook set up to use X11 forwarding with SSH to connect to a remote iMac client in my room for server administration. Whenever I start X client programs on the client iMac, X11 would start on my PowerBook, which is OK, but... Question: Is it possible to change my settings so I can use the WeirdX (a web-based java X server) applet to take care of the X client programs instead of Mac OS X's default X11? Is there a config file I can edit to chance the $DISPLAY variable, and what should I set it to? Is this even the issue? Thank you very much.

  • Windows XP, Preference menu's hidden for many programs

    - by Jestep
    I don't know when this started happening, but it has been several months since I first noticed it. Basically, when I go to a preferences menu of some programs, the preferences window is completely hidden, but the program see's it as being open. This prevents me from interacting with the preferences and the actual program. So far I've noticed it on Adobe Illustrator and Netbeans. Illustrator when I select edit - Preferences - An Option. On Netbeans it happens when I right click on a site and select properties. Here's a link to a screen shot after I click on the preferences menu (I don't have enough points to post an image yet): http://www.jestep.com/images/screen-2.jpg. Note that the main workspace is grayed out. I have to hit Escape to close the hidden preferences window. I've tried unstinstalling, completely wiping the registry of any trace of the program and reinstalling. Thought it may have been a multi-monitor issue when I switched from 2 monitors down to 1, but menu's were not on other monitor when I plugged one back in. I've reset workspaces, windows display, windows performance settings, changed resolution, safe mode, everything I can think of. I cannot figure out what would cause the same problem on completely unrelated software, and I cannot reset it by reinstalling. Any help would be greatly appreciated.

  • BIOS corrupted? How to proceed? Acer Travelmate 290

    - by dtlussier
    I have a older ACER Travelmate 290 (manufactured in 2002 or 2003), which I recently tried to upgrade to Ubuntu 9.10. After doing the upgrade process it appeared as if I had a problem with my x server configuration, as on the first reboot post-install I heard the Ubuntu startup sound, but had a black screen. I thought I would then reboot again to drop down into text-mode to trouble shoot the x configuration problem. However, when I tried rebooting, something went wrong and since then when I start up the machine I get absolutely nothing except the first hardware check (i.e. HDD light flashes, CD/DVD drive spins, etc.). Other than that the screen remains totally black and I have no HDD or processor activity at all. I have tried restarting it a number of time holding down all kinds of key combinations to try and coax it into the BIOS (if possible) with no luck. I have also tried putting in both a live Linux disc and a Windows install disk without any luck. With a disk in the drive it will spin for a few seconds and then stop. All this has lead me to suspect that the BIOS is somehow corrupt (not sure about the right terminology). I have tried putting a new BIOS image and installer program downloaded from ACER on a USB key to see if it will run when I start up the machine, but no luck. I'm not sure if this method of interacting/updating/flashing the BIOS will work outside of Windows/DOS as both OSs are mentioned kind of ambiguously in the documentation. I have also taken the laptop case apart and inspected the various cards and cannot find any obviously burned out components. I'm not sure how to proceed at this point in terms of components to try, or how to try and load a new BIOS image onto the board. Any advice here would be great, especially from those with experience with this particular line of laptops. Thanks!

  • path problem with mod_rewrite, XDebug, PDT, XAMPP and Windows XP

    - by Delirium tremens
    My mod_rewrite turns accounts/create into index.php?folder=accounts&action=create, but pdt ignores it, so when I try to start a PHP Script debug session, I have to type a folder location in the file field and pdt doesn't accept. When PDT auto generates the URL for the PHP Web Page debug session, I go to http://localhost/myframe/index.php?XDEBUG%5FSESSION%5FSTART=ECLIPSE%5FDBGP&KEY=12569067976875, but myframe is in the frameworks folder, so I get a 404 error. When I check a breakpoint, uncheck Auto Generate, add frameworks before myframe in URL, set Start Debug from http://localhost/frameworks/myframe/accounts/create in Advanced and click Debug, the debugger doesn't stop at the breakpoint.

  • Get rid of gray brackets arond editable text in restricted Word docs

    - by Brendan
    I'm trying to work out a problem in Word that I thought was simply a glitch from 2003 until we upgraded to 2010 and the problem persisted. For our corporate letterhead, we set up the template with placeholder text, highlight the text, and then make the document read-only with the exception of the selected text. The editable text turns yellow and gains these brackets around them: Once these brackets appear, they'll always show on the screen. That I can handle, though I'd like to learn how to hide them on-screen if that's possible. When the document is printed while protected, it works fine. When the document is printed while NOT protected, part of the bracket shows up on the paper! I guess the ultimate question is, how can I get rid of the brackets altogether? I can see why they exist but in my use case they create more problems than they solve. I'd like someone to be able to read the doc without seeing brackets, and I'd like other people in my department to be able to print without having to re-restrict it first. I tried to turn off bookmarks because that's what seemed to come up when I searched around, but that didn't do anything.

  • Ubuntu 12.04 froze during update, won't boot

    - by Cichol
    I've recently installed Ubuntu 12.04 on my laptop, and every time i tried to update it, it would freeze for a few seconds, and tell me that the updates could not be downloaded. After many, many tries I managed to get them downloaded, but then in the middle of installing them, it froze. Completely. No mouse movement, no blinking lights, no nothing. After a few hours of letting it sit there, I finally hit the power button to do a hard reset, and now when I select Ubuntu on the boot screen (Dual-boot with Windows 7), I get a blank purple screen, and then nothing. Another freeze. I've tried getting into the console, but no command I input has any visible effect. I have a ton of music stored on the partition it's in, so I'd really rather not have to reinstall. My specs, to the best of my knowledge: Clevo Corp model B7130 (Sager custom) CPU: Intel Core i5 @ 2.53gHz (4 CPUs) Graphics Card: Nvidia GeForce 425m 4096 MB RAM Drivers: Whatever comes with the download of 12.04. As a side-note, I installed Ubuntu via the Windows Installer program (wubi). Does that make a difference?

  • SYS-5016T-MTFB will not POST without manual assistance (Motherboard: X8STi-F)

    - by Dan
    I have a Supermicro 5016T-MTFB 1U server which I am in the process of setting up, but it has a really strange problem. When the system is powered on it will not POST until I press the reset button a few times, followed by pressing the delete key on the keyboard to "wake it up". If I power it on and do nothing, the fans spin up but nothing else happens at all. After pressing the reset button once, the red "overheat" light comes on and blinks which is supposed to indicate a fan failure - but all the fans are working. Pressing reset again usually stops the blinking, and the system starts the normal POST routine but it will not actually get to the bios screen unless I press delete. If I don't press delete, it just continues to hang. After pressing delete it will take me into the bios setup screen, if I exit without saving changes I can boot the system normally. I was able to successfully install Linux with no trouble...but upon rebooting the same problem happened again. This board has integrated IPMI which I thought was the problem, so I disabled it via the jumper on the board. Did not help. Each time this system powers on, it goes on for a second, then turns off again for another second, then turns back on again. I don't know why it does that. Here is what I put in the system: 1 x Xeon E5630 (Nehalem) 80W TDP (it's not overheating, CPU temps stay under 40 degrees C) 2 x Kingston 2GB x 3 DDR3-1066 Memory ECC, unbuffered, unregistered (kvr1066d3e7sk3/6g) 1 x Intel X25-M 160 GB 2 x Western Digital RE3 1TB

  • Which FLOSS text editor is most like kwrite without being KDE-based?

    - by darenw
    Among text editors on Linux, I usually prefer KWrite. I like that I can quickly turn on/off line numbers and line wrap in the View menu. Other settings are easy to change. Other text editors I've used in the past, such as Gnome's gedit, bury line numbering and wrapping checkboxes deeper into the menu system, making it more distracting to change while concentrating on real work. However, KWrite is a KDE app. On Ubuntu it drags in over a dozen other packages, which I suspect I don't really need. Why would a text editor need all that? It's slower to start up than some other editors I've tried. I'm also trying to run an all-gnome system w/o any KDE, just to see how far I get with it. So, what GUI text editor isn't KDE-based, has few dependencies and quick start-up, easy to change line wrap and numbering, and general similarity to KWrite? What comes closest?

  • What's the entry path towards a database administrator job?

    - by FarmBoy
    I've recently lost my job, and I'm working towards changing vocations. My degrees are in Mathematics, but I'm interested in IT, particularly working as a DBA or a programmer. I don't have IT experience, but I have the resourses to be patient with the transition, and I'm currently learning SQL and Java. Obviously, I need some job experience. My question is this: What entry-level jobs might allow me to gain useful experience towards obtaining a DBA job? It seems to me that programmers often start as testers, and system administrators could start at a help-desk position, but it is unclear how one begins to work with a company's database.

  • mod_cache serving the wrong content

    - by J. Pablo Fernández
    I'm trying to use mod_disk_cache to speed up a web site that is running on WordPress. Whenever I enable it with CacheEnable disk / and the rest being the stock Ubuntu configuration I start to get the wrong results. When I see the main page it's fine, but when I go to a specific post I get a RSS feed instead. Like if the cache is returning the wrong content. I've disabled my RewriteRules as it seems mod_cache doesn't work with that. I'm not even sure where to start to debug such a thing. Any ideas?

  • Winamp jump dialog

    - by bobobobo
    In the most recent build of Winamp, either the Jump dialog has been ruined or there's some hidden "advanced" setting that i'm missing. The Jump dialog used to have a few options, like "Jump to file and play" "Jump to file without playing" "Queue file to start playing next, after this song finishes" But now it only shows (CANCEL) as the only button, and you can press enter on a file to start play. What happened to the JUMP & QUEUE feature? I want to jump to a file, but QUEUE it to be played next, not play it immediately.

  • selective backup script in bash

    - by Sake
    Hi, I've been using this simple command (that's all I can do :) to backup the whole tree from my user data in NAS server for a year. cp -r /STORAGE /BACKUP-STORAGE/YYYY-MM-DD Unfortunately, after a year of service. My user start filling the spaces with lot of photo and cliparts (jpg, gif, bmp) And that start to make my backup process get much slower. The space is also a big issue. Now I no longer have enough space for a week-long daily backup set. I think I want to change from backup everything to backup only non-image data. How can I exclude jpg, gif, and bmp from the backup ? It's quite easy with DOS XCOPY command, but I really have no idea how to do that in bash. Thanks

    I have a Macbook that has unfortunately died on me. I randomly got a pop up message that said I needed to restart my computer, and once I did, I was greeted with the blinking folder question mark start up screen. I've tried everything, including running Disk Utility repair and reformatting the hard drive and reinstalling OS X. All of my data is backed up and safe, I just need my computer to start again. Before I go off and buy a new hard drive, I wanted to see if there is anything I might have forgotten.

  • Processor speeds on my machine don't live up to manufacturer hype

    - by atch
    Why am I not seeing the promised speed claims of processor manufacturers on my computer? Producers of processors claim that their product can perform so many thousands (or millions) of operations per second. And yet on my machine (4GB, 3500hz), the typical program (Word, Visual Studio etc.) takes at least 10 seconds to start. I've formatted my hard drive and ticked all the necessary boxes to optimize my machine and yet I'm not seeing the promised speeds. Say it takes Outlook ten seconds to load. How many millions of operations does it really go through in order to start up?

  • Install self-signed certificate on local server (iis)

    - by ile
    On this page there are instructions on how to create self-signed cert (on apache) and how to install this certificate on server. I found this page (http://www.visualwin.com/SelfSSL/) with instructions on how to create self-signed certificate on windows (iis). I followed instructions and when I type https://myip/myapp (this leads to localhost because I set my router's port forwarding to go to localhost on my pc) this part works. From the first link, the most important part is this: What needs to be installed in IE is actually the Root CA Certificate. In the how-to above, the Root CA Certificate is called ca.crt. Copy this file to the server that is running QuickBooks. The following is for IE6: - Open IE - Tools - Internet Options - Content - Certificates - Trusted Root Certification Authorities Tab - Import, Next, Browse to 'ca.crt' - Next, Next, Finish, Close, OK The part that is missing in second link is that there is no instruction on how to get .crt file, so I tried to get it myself. What I did was following: I opened https://myip/myapp in Firefox and then "This Connection is Untrusted" screen appeared. Then I clicked on "Add Exception" and then below "Certificate Status" I clicked "View". Under the Details tab I clicked on Export and choosed Save as type: "X 509 Certificate (PEM)" and file was saved with .crt extension. Then I opened IE8 and followed above instructions. After opening https://myip/myapp in IE8 I always get warning screen. Does anyone knows what am I doing wrong? Thanks, Ile

  • Prevent Roaming profiles from syncing certain elements

    - by user29919
    Hello everyone, I'm somewhat new to the Server 2008 front, and I'm afraid I've hit my first snag: I've set up roaming profiles, and they appear to be working too well. Is there a way to limit, ideally on a folder/object basis, what gets synced with a roaming profile? What I'm trying to do is: 1) stop my roaming profile from syncing desktop layout - I run a dual-screen desktop and a laptop, and it's really annoying to have to reposition everything after logging onto the laptop, because it forces everything onto one screen. 2) stop it from syncing registry variables - specifically, I want Visual Studio to load different setting files on each computer. Currently, the variable that contains that path is getting synced whenever I log in, so I get the settings from whatever box I last logged out from. 3) stop syncing the start menu - this one's not as big, but I'm noticing 'program not found' icons even for programs that are installed. they work when I click them - they just look ugly. I'm running Windows SBS 2008 x64 with two Win7 clients (x86 Pro, and X64 Ultimate). Is there a simple way to do that? Or am I trying to work too much against what roaming profiles are designed for? I could, of course, set up different profiles for the desktop and laptop, but that seems to defeat the point of roaming profiles entirely... Thanks in advance! Any help will be much appreciated =)
