  • Different graphic cards drivers while booting from external media

    - by goran
    I am booting a certain system of mine with ubuntu 9.10 from external HDD. I am satisfied with the setup and it works fine, however I would like to modify it so that I can choose which graphic card drivers to load during the boot time. Specifically I would like to choose between: nvidia proprietary driver ati proprietary driver generic driver Currently if I am using proprietary drivers then dont boot into X, delete xorg.conf, start gdm and reconfigure the system using jockey (for hardware drivers). What would be the steps to make this (semi-)automatic and avoid restarting X?

  • Hard Drive Fundamentals And Verifying Disk Performance

    - by Agnel Kurian
    Over the past few months, my Windows XP machine has slowed down to a crawl. It takes about 10-15 minutes to go from power-up to reaching a responsive state. I have reasons to believe that this is a result of the hard disk slowing down. Questions: Do hard disks slow down as a result of mechanical wear and tear ...or age? How do I check if my disk has slowed down? Conversely, how can I verify that my disk is indeed running at the speed it's designed to run at? Could drivers be at fault here? Do hard disks come with drivers or does Windows use a generic driver?

  • After virus, Chrome & Internet Explorer won't connect to the internet, but Firefox works fine.

    - by Zack
    I cannot connect to the internet with Chrome or Internet Explorer. Firefox works fine. It seems it happens when I was infected by a "Trojan Horse Generic 17.BWIK", "Trojan Horse SHeur.UHL" and "Fake_Antispyware.FAH". I have removed the threats using AVG anti-virus security. I got Firefox working, but Chrome and IE still cannot connect. I do not want to loose Chrome History so re-setting would be my last option and uninstall and install will be out of the question. Is there a way around this? I am using XP Pro on a desktop and DSL connection.

  • Recommendations for stable, reliable flash drives

    - by Josh Kelley
    We're looking to purchase some flash drives for use in some embedded devices. Most of our requirements aren't too different the generic "good, fast" flash drive: reliability is very important, speed is good, and so that the drive will fit, the case shouldn't be too large (so no OCZ Throttles). Consistency is also a major priority; we'd like to be able to buy more or less the same product a year or two from now without having to worry about the manufacturer swapping drive components with less reliable or slower parts. (We've been burned already by our previous manufacturer doing this.) Any recommendations, especially regarding consistency? I can read Ars Technica to get an overview of current models, but what are consistently good models?

  • How can I register a custom protocol with xdg?

    - by julien
    I've been struggling this morning trying to associate an application with a custom protocol, namely emacsclient and org-protocol. I'm calling this protocol from a webbrowser bookmarklet, and I get the following behaviour : In chromium, the "Launch Application" dialog comes up, and calls xdg-open org-protocol://... which ends up firing a new chromium frame. In firefox, I've tried setting network.protocol-handler.app.org-protocol to an empty string or my emacsclient path, anyhow I get the following error message : "Firefox doesn't know how to open this address, because the protocol (org-protocol) isn't associated with any program" without even showing any external application selection dialog. I'm not using any desktop environment, so I need to make this work strictly with xdg, however, despite reading the shared mime info spec etc, I still can't fathom a working configuration.

  • After downloading an application with two Launcher components from the Marketplace, clicking "Open"

    - by user267728
    Create a sample application with two launcher icons. For example, two components such as: <application ...> <activity ... android:name="TestActivity01"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity ... android:name="TestActivity02"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> </application> Either install the application via downloading from the Marketplace, or via AppInstaller.

  • Why are my USB 2.0 devices crashing Windows XP?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine?

    Hi, Friend of mine broke his Windows (doesn't boot). I will probably have to reinstall OS. I want to mount his hard drive in my OS to beck up some important files. He sad he uses Outlook express, but he Use Vista so I'm not sure it's Vistas Mail Client or Outlook. What files I have to copy to backup mail and adders book from Outlook, Outlook Express and Windows Mail? Is it any good program for doing it automatically (for Linux or Windows)? If there are tools or special procedures for other mail clients (for example Thunderbird) you can also name them to make this question more generic.

  • Why doesn't my PHP install see the MySQL extension?

    - by Evan Padd
    So I just set up PHP (Version 5.2.17), MySQL (5.5.28), and Apace (2.2) on my Windows 7 computer. I want to test a mysql connection, but the mysql extension is apparently not loaded (based on phpinfo()). Here's what I did: Changed the extension dir in the php.ini (extension_dir = ".;c:\php\ext") and uncommented the extension=php_mysql.dll line Copied libmysql.dll to the Apache's bin directory Added C:\php to the system's $PATH Restarted the server, then the computer And it's still not working. What did I miss? EDIT: I'm looking through phpinfo()'s outout and it says: "Server API | Apache 2.0 Handler" and I'm running 2.2. Is that a problem?

  • VGA cable casuing resolution issue

    - by LatishS
    Hello, I recently bought a new VGA cable . When connected Windows 7 detects my monitor as a generic plug and play monitor. The resolution goes bad with the screen blurred. This problem disappears when i connect my original VGA cable. Also Windows 7 detects my LG monitor correctly in this case. I am pretty sure it is something to do with the VGA cable but have no idea what could be the possible issue. Any pointers would be very much appreciated.

  • How to charge an iPhone on a Windows PC without Installing iTunes

    - by Martin Hollingsworth
    I want to be able to charge my iPhone on my work computer, which is running Windows Server 2008 SP1 64-Bit. When I plug the iPhone in with the USB cable, it will not charge. Windows attempts to locate a driver for the device but only comes up with a generic Camera device and even if I allow that to be installed, the iPhone still does not charge. I have checked the computer's BIOS settings and did not find anything relating to power on the USB devices. I also tried this on ports at the back of the computer in addition to those on the front. The PC is a Dell Optiplex 780. As far as I can tell USB devices do not charge unless Windows has installed an appropriate driver. Since it is a work computer I do not want to install iTunes which does include a driver. I have a workaround that I will post as an answer for reference.

  • Server refusing access from every host except itself

    - by mezamashiman
    I have media content on a hosted server that I want to be accessed by another domain. In the configuration file, even if I "Allow from all," all hosts except itself will fetch the hosting company's generic landing page, which puzzles me. I test it with curl, with the command: curl -H "Host: anything.com" http://mydomain.com and it just shows the hosting company's page. If I do: curl -H "Host: mydomain.com" http://mydomain.com it will show my content. How do I allow other hosts to access my content? I thought it would work with "Allow" in .htaccess, but it doesn't.

  • Disable Thunderbird "failed to connect" notifications

    - by The Electric Muffin
    My network manager doesn't start until I log in, so for the first ten seconds or so after I login I have no Internet connection. The problem is that I have Thunderbird set to automatically start on login, so it helpfully tells me it "failed to connect" every time I log in. Also, my Internet connection isn't too reliable, so I sometimes get those messages even when I'm supposedly connected. Is there any way to disable these notifications, while still allowing the ones about new mail? Computer info: Thunderbird 15.0 $ uname -a Linux [HOSTNAME REDACTED] 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Probably irrelevant: NetworkManager Version 0.9.0.1 (nm09 20120407) KDE Platform Version 4.8.4 (4.8.4)

  • Why is the size of windows off by 226x238 if defined via the Window Rules?

    - by Bobby
    I have installed Sawfish 1.8.2 from source on my new Ubuntu 12.04 installation following the Debian instructions, but I had this problem also with the stock 1.5.3. Whenever I define dimensions in the Window Rules for a window, the size is off by exactly 226x238 pixels, which means that 100x100 turns into 326x328. That's a very odd behavior, given that Sawfish is saving and loading the dimensions of the windows correctly (if saved via the window menu). Some additional system information: $ uname -a Linux Dagon 3.2.0-24-generic-pae #39-Ubuntu SMP Mon May 21 18:54:21 UTC 2012 i686 i686 i386 GNU/Linux $ sawfish --version sawfish version 1.8.2 nvidia proprietary driver, 9600GT Two monitors, 1920x1080 + 1440x900 in one session. Positionng the windows is working fine, only the dimensions are off by that odd number. Does somebody have an idea why?

  • ubuntu Grub boot hangs on external usb drive

    - by schoetbi
    Hi, i just gave xubuntu another try and installed it ordinarily on a external usb harddisk. I have another harddisk installed inside the laptop that has Windows Xp on it. Now the problem: When I boot from the external drive the boot menu of Grub 2 shows up and i see all installed bootable partitions including windows. Now I select Xubuntu and wait. When the Xubuntu Logo shows up the boot process hangs. Now the funny thing. When the logo shows up I can unplug the usb drive and reconnect it real fast. Then the boot process will continue!!! Since I am a Linux newbie I would appreciate every hint that can solve this so that I can enjoy a smooth Linux boot:-) EDIT Grub version is: tobias@ubuntu:~$ grub-install -v grub-install (GRUB) 1.98+20100804-5ubuntu3 Kernel is: tobias@ubuntu:~$ uname -r 2.6.35-23-generic Xubuntu is 9.10 Thanks

  • How to automatically set default quota limits for users on XFS filesystem, when the new account is created

    - by acidburn2k
    I guess the title explains the problem pretty well. Do you have an idea for a mechanism, which will automatically assign default quota values for every new account created (sort as the skel scheme works, but in this area)? Now, I am looking for a generic clean solution, not some ugly cron based scripts, or wrapper scripts for creating users. I would also like to avoid any external, unmaintained stuff (like forgotten pam modules, and such). Anything what could lead to overhead and extra work in future isn't really the solution, nor is checking for new accounts every minute.

  • USB keyboard not working under Windows 7 x64?

    - by Comboo
    I have two USB keyboards, one no-name cheap thing and an old Logitech. When I plug them in to my computer they pop up in Device Manager as an "Unknown device" and "USB-receiver", respectively. Both of them fail to install any drivers, neither automatically or through Windows Update. Both keyboards work perfectly on another computer I have with Windows Vista 32-bit. Can this be one of those cases where a device does not work in a 64-bit version of Windows? I doubt it though since I've never had that problem before with any device and I thought that basic things like keyboards would be kind of failsafe. I don't really know how to start debugging this issue. I've tried all the obvious, rebooting, changing the USB port, etc. Are there any generic x64 keyboard drivers you can use? Is there any way to find the manufacturer of the keyboard over USB? There is nothing written on it.

  • cheapstuff.com malware

    - by John Peet
    I left my computer off for a couple of weeks and since my Windows 7 updates have been installed I have managed to gather a malware virus. It tries to redirect me on almost all websites I go to. I have read many ways to solving this issue manually, but it seems difficult and I dont want to delete any important files by mistake. All the instructions I have read seem complicated and generic all leading to a company that say they can help remove it. Is it their scam?? Can anybody help by giving me any free software or a descriptive run through for beginners of how to manually remove it? cheers guys

  • Can't display Tool Tips in VC++6.0

    - by Paul
    I'm missing something fundamental, and probably both simple and obvious. My issue: I have a view (CPlaybackView, derived from CView). The view displays a bunch of objects derived from CRectTracker (CMpRectTracker). These objects each contain a floating point member. I want to display that floating point member when the mouse hovers over the CMpRectTracker. The handler method is never executed, although I can trace through OnIntitialUpdate, PreTranslateMessage, and OnMouseMove. This is in Visual C++ v. 6.0. Here's what I've done to try to accomplish this: 1. In the view's header file: public: BOOL OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult); private: CToolTipCtrl m_ToolTip; CMpRectTracker *m_pCurrentRectTracker;//Derived from CRectTracker 2. In the view's implementation file: a. In Message Map: ON_NOTIFY_EX(TTN_NEEDTEXT,0,OnToolTipNeedText) b. In CPlaybackView::OnInitialUpdate: if (m_ToolTip.Create(this, TTS_ALWAYSTIP) && m_ToolTip.AddTool(this)) { m_ToolTip.SendMessage(TTM_SETMAXTIPWIDTH, 0, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_AUTOPOP, SHRT_MAX); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_INITIAL, 200); m_ToolTip.SendMessage(TTM_SETDELAYTIME, TTDT_RESHOW, 200); } else { TRACE("Error in creating ToolTip"); } this->EnableToolTips(); c. In CPlaybackView::OnMouseMove: if (::IsWindow(m_ToolTip.m_hWnd)) { m_pCurrentRectTracker = NULL; m_ToolTip.Activate(FALSE); if(m_rtMilepostRect.HitTest(point) >= 0) { POSITION pos = pDoc->m_rtMilepostList.GetHeadPosition(); while(pos) { CMpRectTracker tracker = pDoc->m_rtMilepostList.GetNext(pos); if(tracker.HitTest(point) >= 0) { m_pCurrentRectTracker = &tracker; m_ToolTip.Activate(TRUE); break; } } } } d. In CPlaybackView::PreTranslateMessage: if (::IsWindow(m_ToolTip.m_hWnd) && pMsg->hwnd == m_hWnd) { switch(pMsg->message) { case WM_LBUTTONDOWN: case WM_MOUSEMOVE: case WM_LBUTTONUP: case WM_RBUTTONDOWN: case WM_MBUTTONDOWN: case WM_RBUTTONUP: case WM_MBUTTONUP: m_ToolTip.RelayEvent(pMsg); break; } } e. Finally, the handler method: BOOL CPlaybackView::OnToolTipNeedText(UINT id, NMHDR * pNMHDR, LRESULT * pResult) { BOOL bHandledNotify = FALSE; CPoint CursorPos; VERIFY(::GetCursorPos(&CursorPos)); ScreenToClient(&CursorPos); CRect ClientRect; GetClientRect(ClientRect); // Make certain that the cursor is in the client rect, because the // mainframe also wants these messages to provide tooltips for the // toolbar. if (ClientRect.PtInRect(CursorPos)) { TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR; CString str; str.Format("%f", m_pCurrentRectTracker->GetMilepost()); ASSERT(str.GetLength() < sizeof(pTTT->szText)); ::strcpy(pTTT->szText, str); bHandledNotify = TRUE; } return bHandledNotify; }

  • Why are my USB 2.0 devices hanging Windows XP?

    - by BenAlabaster
    Background on the machine I'm having a problem with: The machine was inherited and appears to be circa 2003 (there's a date stamp on the power supply which leads me to this conclusion). I've got it set up as a Skype terminal for my 2 year old to keep in touch with her grandparents and other members of the family - which everyone loves. It has a generic ATX motherboard with no identifying markings other than one stamp that says "Rev.B". CPU-Z identifies the motherboard model as VT8601 but doesn't provide me with any manufacturer name. On board it has 1 x 10/100 LAN, 2 x USB 1.0, VGA, PS/2 for KB and mouse, parallel port, 2 x serial ports, 2 x IDE, 1 x floppy, 2 x SDRAM slots, 1 x CPU housing that is seating a 1.3GHz Intel Celeron CPU, 3 x PCI, 1 x AGP - although you can only use 2 of the PCI slots if you use the AGP slot due to the physical layout of the board. It's got 768Mb PC133 SDRAM - 1 x 512Mb & 1 x 256Mb installed as well as a D-LINK WDA-2320 54G Wi-Fi network card and a generic USB 2.0 expansion board containing 3 x external + 1 x internal USB connectors - it has a NEC uPD720102 chipset. It has a DVD+/-RW running as master on IDE1 and a 1.44Mb 3.5" floppy drive connected to the floppy connector. It has an 80Gb Western Digital hard drive running as master on IDE0. All this is sitting in a slimline case. I don't know the wattage of the PSU, but can post this later if this proves to be helpful. The motherboard is running a version of Award BIOS for which I don't have the version number to hand but can again post this later if it would be helpful. The hard disk is freshly formatted and built with Windows XP Professional/Service Pack 3 and is up to date with all current patches. In addition to Windows XP, the only other software it's running is Skype 4.1 (4.2 hangs the whole machine as soon as it starts up, requiring a hard boot to recover). It's got a Daytek MV150 15" touch screen hooked up to the on board VGA and COM1 sockets with the most current drivers from the Daytek website and the most current version of ELO-Touchsystems drivers for the touch component. The webcam is a Logitech Webcam C200 with the latest drivers from the Logitech website. The problem: If I hook any devices to the USB 2.0 sockets, it hangs the whole machine and I have to hard boot it to get it back up. If I have any devices attached to the USB 2.0 sockets when I boot up, it hangs before Windows gets to the login prompt and I have to hard boot it to recover. Workarounds found: I can plug the same devices into the on board USB 1.0 sockets and everything works fine, albeit at reduced performance. I've tried 3 different kinds of USB thumb drives, 3 different makes/models of webcams and my iPhone all with the same effect. They're recognized and don't hang the machine when I hook them to the USB 1.0 but if I hook them to the USB 2.0 ports, the machine hangs within a couple of seconds of recognizing the devices were connected. Attempted solutions: I've seen suggestions that this could be a power problem - that the PSU just doesn't have the wattage to drive these ports. While I'm doubtful this is the problem [after all the motherboard has the same standard connector regardless of the PSU wattage], I tried disabling all the on board devices that I'm not using - on board LAN, the second COM port, the AGP connector etc. through the BIOS in what I'm sure is a futile attempt to reduce the power consumption... I also modified the ACPI and power management settings. It didn't have any noticeable affect, although it didn't do any harm either. Could the wattage of the PSU really cause this problem? If it can, is there anything I need to be aware of when replacing it or do I just need to make sure it's got a higher wattage than the current one? My interpretation was that the wattage only affected the number of drives you could hook up to the power connectors, is that right? I've installed the USB card in another machine and it works without issue, so it's not a problem with the USB card itself, and Windows says the card is installed and working correctly... right up until I connect a device to it. The only thing I haven't done which I only just thought of while writing this essay is trying the USB 2.0 card in a different PCI slot, or re-ordering the wi-fi and USB cards in the slots... although I'm not sure if this will make any difference - does anyone have any experience that would suggest this might work? Other thoughts/questions: Perhaps this is an incompatibility between the USB 2.0 card and the BIOS, would re-flashing the BIOS with a newer version help? Do I need to be able to identify the manufacturer of the motherboard in order to be able to find a BIOS edition specific for this motherboard or will any version of Award BIOS function in its place? Question: Does anyone have any ideas that could help me get my USB 2.0 devices hooked up to this machine? Edit: Updated the USB 2.0 info with reference to actual card - http://www.xpcgear.com/lpnec4u.html
