Black screen on Isight when in IChat

When my wife contacts me via Ichat with an Imac, I can't see here. Audio is fine. She can see me fine, but her screen of me freezes up.
When viewing her screen via built in isight camera, it is black.
I'm using a MBP.
Any suggestions?

Hi,
I have re-read your post several times.
I still can not work out what you are trying to tell us.
I seem to understand that when she initiates the call She gets Video and Audio fro you which displays fine.
However you can not get a picture from her - and if this is from her Built in iSight the picture is in fact black ?
Can you open the Connection Doctor during a Chat (It is in the Video Menu) and tell us if it says there is any Video feed ?
Also what is the incoming Bit rate showing as ?
You seem to also be saying that even though your wife can see you at the start of the chat that your pic that she sees in fact also freezes ?
Have I understood you correctly ?
Could you also tell us what your Internet connection speeds are both Up and Downloads at both ends ?
Have you (both) made the change to System Preferences > Qucktime > Streaming to 1.5Mbps ?

Laptop black screen with mouse when booting from shutdown [solved]

Ok I am kind of at a loss at the moment. I have done a fresh install of arch for a friend. When I boot the laptop from a shutdown status it boots and I see systemd proccessing, but as soon as it reaches the desktop it is just a black screen with the mouse cursor. To reach the desktop I have to press ctl alt f1 than ctl alt f2. Here are some things I have done to tryand fix it.

ok, so I think I have foud a solution that works for me.
I created this file and added the following lines
/etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
Identifier "Intel Graphics"
Driver "intel"
Option "AccelMethod" "uxa"
EndSection
I have shutdown 3 times and it has booted to the desktop everytime. When I remove this file and go back to sna it reproduces the error of the black screen.

Black Screen with curser When Installing Windows 7 on Mavericks

I have been trying to install windows on my macbook pro via bootcamp all day today, i have put about 7 hours into it and i am very frustrated. I have followed the guides. I have updated my mac, installed the windows support drivers, i have the most recent bootcamp, I have windows 7 on a DVD with a usb optical drive.
So my problem comes when I get to installing windows. after i make the partion on bootcamp it trys to reboot to windows but instead goes to a black screen with curser. i have gone online and read through tons of forums that talk about this exact problem. i have attempted what they suggest such as booting while the usb with the windows support drivers is connected and boot to the windows disk using the option at boot. (Still black screen with curser) I have tried booting to the windows disk with no other external usbs attached but the optical drive. (still black screen). i have tried booting to another disk part of the DVD callled " EFI Boot" that pops up when holding option at boot up. When doing this windows 7 actually does start up and starts the install process but when choosing the bootcamp disk to install to, it says it is the wrong format. so i tried to format it in the windows install as people have said but that did work. But people have also said on other forums that you cant boot windows using the EFi Boot or what ever its called so i dont think that is an option. I have repeatedly deleted the bootcamp partion and tried to partition it again but still get the black screen when booting up.
My mac is a Macbook pro mid 2012. It also is a mavericks whitch i have seen caused many others problems with bootcamp. so i have seen many answers to the black curser screen but none have worked with me. Do you guys have any suggestions or questions for me that would help me get this figured out? Thanks for the Help!

Simple fact is IF you have replaced the original built in DVD drive with a second HDD you will never be able to install Windows on your Mac, or at least not easily.
Apple has restricted Mac computers that originally come with a built in DVD drive to only install Windows from that built in drive When It Is Installed Inside the System.
These Mac's will not boot from the Windows installer from any other source, not USB stick or USB connected DVD drive no matter what make or model DVD drive it is.
So there are only three option.
1) Reinstall the original DVD Super drive in the Optical bay and whatever drive you want Windows install on to the main bay, install OS X on that drive in the main bay then use Boot Camp Assistant to install Windows. Once that has completed you can then switch around the drives to your liking.
2) Reinstall the Super drive to the Optical bay and whatever drive you want Windows install on to the Main bay. Do not install OS X and install Windows natively on the drive in the Main bay. The Windows 7 (and maybe a Win 8) DVD will boot the Mac computer from the DVD drive and you should be able to run the Windows installer, Partition and Format the drive for Windows only, MBR partition table, and complete the install of Windows on that drive. Then load the Apple Supplied Windows Support files you downloaded once Windows has finished the install.
Then move your drives around where you want them and install OS X on the other drive.
3) There are reports of being able to copy the Windows install files to a partition on one of the drives you will be using and then run the Windows setup, installer, from that partition. I have no information on exactly how to do that.

Black screen on skin when closing movie

We have been using Captivate v1 successfully with our LMS and
have started testing Captivate v2.
We really like the new skin feature however when the student
finishes the movie a black screen apprears (looks like the skin
with a black background) just before the window closes. It is not a
show stopper but annoying. If I publish without the skin this does
not happen. I've checked the skin background and it is set up as
white.
Any ideas why the skin flashes a black background before
closing?

Answered my own question.
Even though the setting in Skin Editor>Borders tab has
HTML background color the black flash after closing the movie was
coming from the Border Color. I simply changed the black to desired
color. Now it closes fine.

Windows 2008 R2 Failover Cluster - Netapp FAS6280 Black Screen on Restart when in cluster IGROUP

Hello everyone,
I've been working on this issue for a month now and have tickets open with Netapp and Microsoft. We have not been able to resolve the issue as of yet and since I'm losing all my hair I thought I should post it...
Scenario:
Two Windows 2008 R2 Enterprise SP Fail-Over Clusters (C1 & C2)
Two Netapp FAS6280 Filers for SAN storage
8 DELL R815 servers w/ 2x QLE2562 8GB FC HBAs all paths used (9.1.9.47 - newer did not resolve)
Netapp DSM 4.0 & SnapManager 6.4.2 (we also tried 1 rev newer, 1 rev older without luck)
C1 has 2 nodes & C2 has 4 nodes.
We are trying to add new nodes into the clusters. We were originally on EMC Clariion arrays and have been migrated to the netapp. Prior to moving we had 3 nodes in C2 and added node 4.
Now we want to add 2 more nodes, one to each cluster. We were able to configure the OS and get everything installed and matching the other nodes. we can assign HBAs to a test IGROUP and assign a lun, format it use it restart all is well and normal.
As soon as we change the HBAs to the IGROUP for C1 or C2's LUNs the servers don't want to restart properly. They hang at a black screen. The little green windows start splash screen runs the bar at the bottom. it then is supposed to fade
out and come back with the grey screen saying starting windows but that doesn't always happen. Sometimes it can take 4 hours to restart, or the machine will not come back onine at all. The pre-existing nodes *do not* experience this issue.
They restart in 5-10 minutes without issue.
We know drivers are part of the issue, but the maddening part is that it all works fine until we try to add the HBAs to the existing cluster storage group. We have a suggestion to create separate IGROUPs for each cluster node and add all luns to the
separate igroups. We configured this on one node and it still restarts long. We plan to modify the other nodes during our maintenance window and try again.
On the other cluster we were able to successfully complete the validate wizard and join. everything fails over and works except the server does not come up upon restart. If I unplug the HBAs it will come up fine, then I can plug them in and the
cluster functions.
Does anyone have any other ideas for us to try? Currently support for both netapp and Microsoft appear stumped. Sunday is our Window and we plan to try reconfiguring but I'm losing optimism...
Thanks for any feedback/ideas!
-Ryan

Thanks everyone who looked at this and offered feedback.
The issue appears to be resolved after the configuration change suggested by Netapp support.
The originally recommended configuration for our storage migration was similar to how I've seen storage groups configured on EMC arrays in the past. 1 storage group / igroup with all hbas/initiators for each host in the WFC/SQL cluster added to this
group. that group then gets all LUNs assigned to it.
The change in configuration that was recommended is to have 1 storage group / igroup for each host and put all initiators/hbas for each host in their own separate group. Then assign the all LUNs to each of the individual host igroups.
There is a lack of documentation on this, but it appears to work. We had 1 hit for separate igroups but had to go through a couple of support techs to get one to confirm this.
After applying this configuration in our change window today the issue is resolved. we were able to fail all resources onto the new node and restart it without issue. The question remaining for us is why the old systems continued to work while
the new nodes did not. The old nodes were originally migrated off an EMC and the version of ONTapp at that time was 8.1.2 and they worked fine.
We had upgraded to 8.1.3 to resolve an issue with flash cache and it seems like machines that we tried to attach to this igroup after that time did not work. all drivers software etc the same. We are wondering if this is somehow related and have
asked about it.
I wanted to update this thread, and perhaps it can save someone else some trouble down the line.

Black screen but vibrates when charging

You'll need to reload the OS software to the phone.

Blurry Built-In iSight when using iChat

I have a new 20" iSight iMac and seem to be having an issue with using the iSight w/ iChat. The picture looks perfectly clear in my preview window, until the moment where it actually connects with another user, at which time it immediately goes blurry as if the camera has completely lost focus. I've tried on multiple occasions, connecting to people who also have an iSight/iChat with everyone having high-speed connections.
This seems like a bug to me, and there's no way to manually focus the camera until/unless iGlasses comes up with a version that's compatible w/ the new iMacs. I've searched and seen this problem mentioned a few times on the boards, but have yet to hear a solution or even whether this is something fixable or not.
Thoughts?!
20" iSight iMac 2.1 gHz Mac OS X (10.4.3)

It's certainly possible there's some kind of bandwidth detection going on that made it blurry, but it doesn't make sense that it would make the picture BLURRY, rather than make it lower quality (more pixalated). I have a cable connection that has a very fast upload speed, so if there was a bandwidth problem, it wasn't likely on my end.
Today I connected w/ a neighbor and didn't have the blurry problem, though I did have the problem with the other two people I've tried it with.
Next time it happens I'll check the connection doctor to see what it says. I should also note that when I connected to the same people using a stand-alone iSight, I did NOT have the 'blurry' problem. It seems to be confined to the built-in camera, and again it looks fine until it actually connects to someone.

IPod touch black screen, not recognized when plugged in

I just brought myself an iPod touch 4th gen so I decided I would give my old one to my brother so I was clearing it off for him and some other things when I accidentally pulled it out of the computer I then pressed the sleep button to turn it on but the screen remained black so I tried plugging it back
In the computer but it shows it as a unknown device then I tried plugging it into the wall charger which didn't work either. My friend thinks it might be in dfu mode but if it was wouldn't the computer still recognize it? Any suggestions? Please and thank you :)

Black screen with iSight MacBook

If I go into QT Pro, click, file, then new movie, the green light on the iSight comes on, but the recording window is black. It will not record. It worked before. Nothing has changed, permissions repaired. Any ideas?

I would take it in, It could be graphix card, display, cable, lose connection. No easy resolve on your part.

My Macbook air (only 2 months old) has a black screen and I cannot see to get signed on, the keyboard seems to be on as I can see via having put on the Caps key which lights up and also the power cable when connected is at green how do I fix this?

I have been faced with a Black screen this morning when I have gone to sign in/open my Macbook air this morning. I can see that the keyboard seems to be on as the caps key when pressed is lighting up as is my charger cable link, however have noticed that the apple logo is not lit up. Any thoughts?

Try resetting SMC and NVRAP and then reboot.

http://support.apple.com/kb/PH4405
Try booting the Recovery Partition. Power off, boot and then hold down the Command and R keys. Is the screen still black? If so it is not a software problem so take it in for diagnosis and repairs. Make a Genius Bar reservation http://www.apple.com/retail/geniusbar/ or find an Apple Authorized Service Provider https://locate.apple.com/country .
If you are running Mavericks try upgrading to 10.9.2. It has a fix for black screen problems.

When I create an album and then try to watch it in slideshow, I get only a black screen with a white title. No photos come up. Also when I click on an individual photo in the album, I get a white exclamation point on a black background but no big photo.

When I create an album of photos and then open the album and try to watch it by selecting "slideshow" I get only a black screen. The white title comes up briefly but then no photos, only a black screen. Also when I go back to the album and click on a thumbnail, up comes a big white exclamation point on a black background instead of the enlarged photo. Any idea what's going on?

The ! turns up when iPhoto loses the connection between the thumbnail in the iPhoto Window and the file it represents.
Option 1
Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Rebuild iPhoto Library Database from automatic backup.
If that fails:
Option 2
Download iPhoto Library Manager and use its rebuild function. This will create a new library based on data in the albumdata.xml file. Not everything will be brought over - no slideshows, books or calendars, for instance - but it should get all your albums and keywords back.
Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one. .

How to flash bios for aspire 5745 when you have a black screen

I attempted to update my bios for my Acer Aspire 5745 notebook and chose the wrong file. The computer is giving me a black screen now. When I push the start button the lights come on the fan blows and thats all. I found a few sits on line giving me the procedure to flash an aspire one system. Here is the steps I took to do so to no avail. 1. When to the acer site and put the SNID number to my laptop to pull up my suggested downloads for my system. 2. I downloaded the file to my working computer. 3. I extracted the file and opened the file that said DOS. 4. I renamed the file zg5ia32.fd 5. checked my flash drive to make sure it is set to ( FAT ). 6. Transfered the file to the flash drive. 7. Pluged in the flash drive to my dead laptop while it was pluged into a powersorce. 8. Held down the FN and ESC buttons while pushing the power buttons. 9. Released the FN and ESC buttons when I noticed the power light blinking and the flash drive light up. 10. Waited for over 15 min. but had no success. If anyone could tell me what I may have done wrong I would be much appriciated. I also opened up the backside to the laptop and removed the little battery that was plugged it with a small white connector assuming it was the cmos battery but still nothing happended.

I was never able to properly flash my bios. I had wondered if when I tried to update it I may have destroyed my bios in the process. Anyways I had purchased a motherboard for I think around 50.00 on ebay. It was used but was complete. All I had to do was take out the old motherboard and replace with the other one. It all came on after that with a new knowledge of not fix something that is not broken.
