Problems using the brightness after upgrading to 10.11.4

I ran into an issue today after the upgrade to El Capitan 10.11.4. It seems that the upgrade while she fixed some issues caused my buttons with the brightness of the screen (F1/F2) no longer be functional. All other keys on the keyboard are functioning normally.

Is this a bug in the software, or is there something I can do to fix this?

You can provide any help would be greatly appreciated.

Thanks R

Check-> keyboard-> keyboard system preferences and make sure that the "Use all F1, F2, etc. as standard function keys keys" option is NOT selected.

  • Problem with the rules after upgrade of the VM in foglight cartridge

    Hello

    There is a small problem with the rules after that I updated the VM cartridge level.

    In the default rules, I changed a few settings so that they will act as I need.

    However, each time I upgrade VM cartridge my rules are off and marked as backup.

    The question is: is there a way to upgrade the cartridge and keep my active rules after upgrading?

    Best regards

    Victor

    This is the normal behavior according to this KB article

    • Title

      Backup rules fill in the dashboard management rule after Foglight upgraded
    • Description

      After that an upgrade of Foglight was conducted, several backup rules are created for rules that have been published before the upgrade. For example:

      Cluster VMW IO network
      Cluster VMW IO network (backup)

    • Resolution

      During the upgrade procedure, the FMS has detected that some of the original rules have been changed in some way. It copies the rules previously upgraded in backups, before trying to merge the contents of the update rule in the former.

      Assuming that the FMS works as expected, the rules of backup can be deleted. However, it is best to confirm this in the respect of the rules first before making deletions.

      When editing rules, particularly rules OOTB (out of the box), it is recommended to copy the original rule, disable the original rule and edit the copied rule. This should reduce the risk of the problem described in this Article.

  • Have problems with the Audio after upgrade to Windows 10

    I got a free upgrade for Windows 10 option on my laptop Acer Aspire SW5-011. Everything seemed to work fine, except that I don't bother checking the audio before deleting the files Windows 8... Even if the computer thinks that the Audio drivers work very well that they are not. I have tried everything that I could find online to see if I could get any sound, but nothing has worked. I updated the drivers, kidnapped rebooted and updated the drivers, I tried to find the other acceptable drivers and other follow-up steps. "When I go to reading tab in the sound and click speakers, and then I go to the Advanced tab, the default format said, ' 16 bit, 48000 hrtz ' is grey, I can't click on it and when I try to test it says:"Cannot play testtone" It's as if something prevents me from accessing or it acts like I'm not pregnant? The speaker driver is called "Intel SSD Audio Device. The audio worked fine before downloading. Is it possible to fix my Audio, or to have access to it yet?

    Good so I had to update my post because I had to give the good news! However, that is how I am and I almost try everything and tinkering with different things. My audio works now. I went back the download Acer drivers and manual for my camera and I checked under 32-bit Windows 8, which was windows available. I installed my ID which has been deleted before when I had restarted or any number of things, I tried, and then I went in Drivers and installed the Master Installer. I made sure that I extracted all the files before proceeding with the installation. After it restarted my laptop I heard the Windows startup sound and I knew that it worked because I had no sound at all before. Not sure why it worked, but it did! I felt there was some sort of missing file or a compatibility issue, I'm just happy that the program helped master installation. http://us.acer.com/ac/en/US/content/drivers/5687;-; SW5-011 #_ga = 1.21697787.1131678756.1448199856

    an old computer, but it works very well.  I want to switch to XP using the Windows upgrade disc. But

    in the specifications it lists only 98, 98 Second and ME as an operating system you can upgrade.  Thanks John

    Provided the specifications of the computer meets Windows XP you can switch from 2000 to XP. If it does not meet the specifications, you may upgrade the computer first or get a new one which is more cheaper today.

    In addition, please note that you can only switch to Windows XP Professional. If it is a home edition you have then it will not work. You can refer to the link below on how to update your copy of Windows 2000 to Windows XP Pro.

  • problems using the snap have amd, playback of Jpeg files

    Original title: I'm having problems using the component feature snap-in.

    Sometimes a single document disappears. When this happens while the document program is managed by then will not work. The document seems to be flying around the office. The last time this happened I had a doc JPEG upward and now I can't see what is JPEG. I don't know why the document wants to fly around, and I don't know how to get my use of the JPEG back.

    Hey Graham,.

    To view all jpeg images in the Viewer Windows photo or any other photo software visualization, you must configure this software as a default value in the default programs.

    Check out the link that allows you to configure the program as default.

  • Problems with the brightness and color in a motion tween + canvas

    Hello

    As the title suggests, a simple (html5 canvas doc) motion interpolation of an instance (let's try a pink square) which will become red, works perfectly in animate CC but not in the browser?

    The same happens when I use the brightness with or rather the color.

    I use the classic motion tween.

    Any idea?
    Etirod (French language)

    The top color effects or filters are likely to cause the image is cached bitmap, and you lose the effect. When you perform a test of Animate, look in Control Panel output for all warnings.

    You can often get a similar effect by having both variants you need on top of the other, then simply change the alpha of the forefront one.

    I'm having a problem using the slideshow module in LR 6.3. The slideshow contains the background image as one of the images to display. Earlier, I have created a slideshow of practice and the background image was not displayed as an image in itself. How to make it behave?

    Another approach, perhaps a little more elegant (?). Create a collection that includes images for the slideshow. Include the background image in the collection. Drag the background image in the Panel to designate. Then, remove this image from the collection and create the slide show. I just tried and it works, too.
