I tried downgrading mesa, mesa-libgl and intel-dri to their previous versions (9.1), but it didn't help. Is anyone else experiencing anything similar? What are your suggestions?
Thanks in advance.

My X220 laptop has a DisplayPort which I plug in a DisplayPort to HDMI adapter to connect to a TV.  Working fine here after I updated this morning.  The X220 is Intel SandyBridge (HD3000 I believe).

  • Hdmi connection not being detected on tv

    So when I plug the hdmi into my computer through the adapter, it is no longer showing up on my TV, saying 'no signal'. It was working earlier today but now its not.
    When I plug it it, the screen flashes like usual, but nothing happens. When I look in the displays part of system preferences, it knows its attached, but it still doesn't do anything.
    So far I have tried taking it out and plugging it in again, restarting the computer, restarting the NVRAM because thats what another support thread said but none of them have worked.
    I'm not sure if this is a problem with my computer, my TV, or my cable, but if anyone could tell me whats wrong, I would greatly appreciate it.

    Your problem may be as simple as an HDMI cable that has gone bad, or.
    Your television may have had its HDCP (High-bandwidth Digital Content Protection) credentials removed.
    Sometimes a display can be HDCP certified and then later be removed from the certified list. So purchasing a new display (TV) may not be a permanent solution.
    Your display may not be on the "approved" list, or was removed from it.
    The Hollywood demanded technology is called High-bandwidth Digital Content Protection (HDCP) and aims to prevent copying of digital audio and video content as it travels across a variety of display connectors, even if such copying is not in violation of fair use laws.
    I have occasionally offer methods for fixing this but my post gets deleted.   Suggest you search elsewhere on the Internet for advice or purchase another television.

  • Hp v235r flash drive not being detected on my computer

    Hi,
    I am using hp v235r flash drive for more than 5 years. It's not being detected on my computer since two days. Can any one solve my problem, as there is lot of important data stored in it and hasn't been backed up recently.

    Hello budda48,
    Its possible the driver for the pen drive is corrupted in your computer, or the drive has met its end of life.
    First, confirm that the Pen Drive is seen by other computers. Plug it in to another computer that you havent tried yet.
    If it is not working on other computers, then the usb drive is corrupted and there wont be anything else we can do.
    If it is working in other computers, then try these steps to troubleshoot the Pen Drive.
    Confirm that the port on the computer is not bad. Choose a different port to insert the drive. Next…
    Part 1: Make sure that the drive has a drive letter assigned in Disk Management.
    Open Computer Management by right clicking on Computer and clicking Manage.
    Click on Disk Management. Give it a moment to open the view of the drives installed.
    Look for a drive that does not have an assigned drive letter and is not labeled as System Reserved.
    Note: System reserved drives are reserved by Windows and will not allow you to assign a letter.
    Right-click the unlabeled drive and click Change drive letter and paths…
    Click Add and then click OK to select the first available drive letter.
    If the Change drive letter and paths… option is not available, make sure that the drive is Online.
    If the drive is Offline, right-click the disk number and click Online.
    Part 2: If the drive does have a letter assigned and it still does not work, uninstall the driver.
    You can safely remove any usb drivers that are not in use (hidden drivers). Devices that get plugged in later will simply reinstall its needed driver again.
    Remove the pen drive from the computer if it’s attached.
    Right click Computer and click on Properties. In the System window on the left side, click on Advanced System Properties.
    Choose the Advanced tab and click on Environment Variables… button at the bottom.
    Under System Variables, click on the New… button
    Type this in the box that pops up. Variable Name: devmgr_show_nonpresent_devices and also give the Variable Value: 1
    Click OK on all the open windows to close them out.
    Go to Computer Management again and click on Device Manager. Go to View at the top of the window and click on Show Hidden Devices.
    Click on the drop down arrow for Universal Serial Bus Controllers to open the list. Look for any USB Mass Storage Device that is hidden (greyed out) and delete it. There may be several and it’s ok to delete all those hidden USB Mass Storage Devices.
    When you connect the pen drive to the computer again, give it a minute to reinstall the driver.

    Solved!
    Go to Solution.

    To solve the issue, open Device Manager on your computer to reinstall the driver for your device while your device is connected with your PC via a USB cable.
    Microsoft Windows Vista and 7 users
    To open Device manager on your computer
    Click on the Start button. 
    In the Search box, type device manager, and then press enter. 
    To reinstall the drivers for your device
    Scroll down to the Universal Serial Bus controllers (USB section) of the Device Manager window. 
    Look for an MTP Device: Media Device, Unknown Device or any other reference to your phone. Click on this entry and choose "Uninstall" whilst leaving the device connected. 
    Wait a few minutes, and the computer will reinstall the drivers for the device.
    Now, the phone is accessible via Computer/My Computer on your computer.

  • Ipod 4g 32G not turning on, not charging (on multiple cords, both comp and wall, 4 20min), not being detected by Itunes or Windows 7 64bit OS, will not reset, tried taking it out of "DFU", NO DMG, Itunes up2date, All I'm getting is a blank black scrn

    Ipod Touch 4th generation 32G not turning on, not charging.
    I have used multiple cords on both computer USB and wall USB converters. I let it sit there for over 20 min with each attempt.
    It is not being detected by Itunes or my Windows 7 64bit OS. I have tried all 4 of my USB ports (both USB 2.0 and 3.0), with 3 different chargers.
    Holding home and power button will not reset.
    Tried taking it out of "DFU" mode but Itunes won't detect it, I didn't think that would work anyway.
    NO DAMAGE, I have been very careful with it, aside from a few minor scratches. (that you can't even see unless the light reflects them)
    My Itunes is up to date, as is my OS.
    All I'm getting is a blank black screen. It has been working fine on this computer before. I have no idea what could have happened. I'm at my wits end here.

    See if you missed anything here:
    - iOS: Not responding or does not turn on           
    - Also try DFU mode after try recovery mode

    - If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
    - Try another cable              
    - Try on another computer                                                       
    - If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

  • HT203128 My iPad is not being detected by iTunes after I updated to the latest version of iTunes.  What should I do?

    After updating to the new version of iTunes, my iPad 2 is not being detected when I tried to sync.  Any solutions?

    A few things to try. Any one or a combo mayhelp
    Reset your iPad.
    Hold down the sleep and home keys for about 20 seconds. Then plug it back in and see if it is seen now.
    Try a different USB port
    Reboot your computer
    If you have a PC:
    If that doesn't fix it, go into the control panel, add/remove programs. Uninstall iTunes, apple Mobile device service, apple application support.
    Then redownload and reinstall iTunes. then try again.

  • Battery Not being detected

    Hi there,
    My Hp Envy m6 has started saying that the battery can't be detected but it was working fine yesterday and my battry was fully charged. I've had the laptop for 2 years now and I've taken good care of it so I don't see how I would need to replace the battry so soon in the computers life

    Hi @michelleprins74
    Welcome to the HP Support Forums! I saw your post regarding the problem with the battery not being detected. I will be happy to assist you with that. Try this post of mine from another HP thread which includes a link on testing and calibrating the battery for both Windows 7 and 8. There are also some steps on resetting a couple of battery drivers.  Give that a try and let me know how it goes.

  • My Ipod Nano 5th generation is not being detected by Widows and Itunes. I have tried everything based on the trouble shooting tips outlined. Has anyone had this situation before? How was it resolved. My Ipod is just out of warrenty

    Have done all trouble shooting tech a through Apples and still have not resolved issues on Windows and itunes not detecting my Ipod  nano 5th generation device. Tried restoring the device manually using disk mode and still not being detected by the computer. Device is our of warenty as when service repair charges are $125.00 dolars more than I paid for this device. There must be some way to restore the entire device to factor settings without having to be connected to itunes and Windows. I wish I could connect but again device is not being read. I have another Ipod that is 8GB instaed of 16GB and it works fine. The sad thing about this situation is that my 9year old daughter worked hard doing delivering fliers for a long time to save her money to buy this 16 GB 5th generation Nano. Otherwise the Ipod works well but will not syncronize songs as it is not being detected. Maybe this is a result of corrupt files that got onto my daughters Ipod somehow and thus causing it not the be detwected through the USB connection thus as a result not be understoud as a working device through Windows and itunes. If anyone can help me out there including itune techs that would be well appreciated, but for now my daughter is not able to add new or delete any songs on her ipod as well pictures, and everything. Thanks

    Try changing the cord. I could NOT get my computer to recognize my iPod 5th Gen until I read somewhere that different apple devices use different cords. I was inadvertently using my iPad cord and that caused my computer to not recognize my ipod.

  • My iphone 4 is not being detected by any of my computers and not charging when connected to any computer.  It will, however, charge to the car or wall.  The only change that I can think of is that I downloaded a podcast from itunes directly from my phone.

    My iphone 4 is not being detected by any of my computers and not charging when connected to any computer.  It will, however, charge to the car or wall.  The only change that I can think of is that I downloaded a podcast from itunes directly from my phone.  I've since deleted this podcast with no luck.  I've restarted both the phone and the computer, still no luck.  One computer is running Vista and the other Windows 7, both have the latest Itunes Update.  Anyone have a fix for this?

    If you can't get it to shut down or restart when holding down the Home and Sleep/Wake buttons and you can't get it recognized in iTunes to restore it, the iPod may have suffered a hardware failure and will need to go to Apple for service. Someone else here may have additional suggestions, though.
    There is no "fifth generation" iPod touch, by the way, just for the sake of clarity; not yet, anyway.

    iPod 5 and iPhone 6 is not being detected after I downloaded iTunes 12.1.2
    Tried changing the lightning conductor, that didn't help either.
    Re-installed iTunes but it was of no use. :/

    See iPhone, iPad, or iPod not recognized in iTunes for Windows - Apple Support
    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down the page in case one of them applies.
    The further information area has direct links to the current and recent builds in case you have problems downloading, need to revert to an older version or want to try the iTunes for Windows (64-bit - for older video cards) release as a workaround for installation or performance issues, or compatibility with QuickTime or third party software.
    Your library should be unaffected by these steps but there are also links to backup and recovery advice should it be needed.
