Buddies see black screen when connected

I connected to a few people with my webcam (in my new macbook) and all they see is a black screen...some people see it..some dont..what should those that cant see it do? or what is causing this?

Hi Sunkentheory,
When you click your own Video icon do you see a preview ?
IF you go to iChat > Preferences > Video do you see the same preview ?
Do you have any add-ons to iChat ?
Does the green light come on for you internal camera during a chat ?
Does this page help any ?

[SOLVED] black screen when connecting rdesktop to localhost

I am trying to set up my machine so I can remote into it via RDP.
When I run the command
rdesktop localhost
from my terminal rdesktop pops up. I choose sesman-Xvnc and type in my password and a plain black screen is all I get. Sometimes I'll get a message that says "Oh no Something has gone wrong. A problem has occurred and the system can't recover. All extensions have been disabled as a precaution." It also gives me a log out button.
I have installed xrdp from the AUR via yaourt. I am using xrdp version 0.6.1-1, tigervnc 1.4.0-1, and rdesktop 1.8.3-1.
In trying to isloate the problem I tested tigervnc by running
vncserver
with the following xstartup configuration file in my /home/.vnc directory.
#!/bin/sh
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
OS=`uname -s`
if [ $OS = 'Linux' ]; then
case "$WINDOWMANAGER" in

if [ -e /etc/SuSE-release ]; then

I've tried restarting vncserver.service with systemctl and I get the same error.
Per the vncserver wiki I created a vncserver@:1.service file in /etc/systemd/system and enabled it. It starts and runs without a problem.
I have tried using the nouveau video drivers instead of the nvidia driver that I'm currently using and that produced a similar result but with a white square at the upper left hand corner of the rdesktop window.
I'm new to arch-linux and linux in general. I've been using it for about a month now and I've been able to solve all of my problems through using this forum, reading wikis and the man pages of command line programs. This one has me completely stumped.
I have no reason to believe the problem is related to xrdp or to rdesktop because the only errors or decent information I have been able to find about what could be going wrong has been the vncserver.service error shown above.

Ok. I finally got this working. What I did was I created a file at /etc/systemd/system called vncserver@:4.service and set the user in the file to my username. Then I went into xrdp.ini which is located at /etc/xrdp and under [xrdp1], (which is for sesman-Xvnc ) I set the port value to 5904 which is the port that my vncserver@:4 service uses when its running.
Since xrdp uses tigervnc as its back end it was just a matter of pointing it to a running vncserver.
Don't I feel silly
Thanks Knute for your help. Your idea led me to the right answer.

Dell U2711 black screen when connected to Mac via DisplayPort

I currently have a Dell U2711 27" monitor connected to my Mac Mini through DVI (it uses a DVI to mini-DVI adapter at the PC end). However, I cannot get the full resolution of the monitor 1920 x 1080 maximum is offered were the monitors maximum resolution is 2560 x 1440.
I did some Googling and seemed it required DisplayPort connection to achieve this. No dramas. I ordered a Mini-DisplayPort to DisplayPort cable.
I plugged this in and all I get on the Dell is a black screen. The monitor doesn't go into power save mode or anything like that, just displays nothing - an illuminated black screen.
I pulled out my MacBook and connected the cable to that, same deal. The Mac recognises that the cable has been connected (as the laptops LCD goes blue for a second or two while it detects the new monitor).
Any ideas?
I also had a DisplayPort to DisplayPort cable here which was included with the monitor from Dell, which I will test aswell when my miniDisplayPort to DisplayPort adapter arrived.

Yes, that is one means, but...
However, HDMI 1.3 can also carry resolutions higher than 1920 x 1080 - check out http://en.wikipedia.org/wiki/HDMI - not really an option on the Dell monitor though, as it only supports up to 1080p on the HDMI connection. However, there is a thread elsewhere on the internet of a user who forced his Windows laptop to use 2560 x 1440 resolution via the HDMI output and the Dell monitor accepted it!
In addition, so can DisplayPort - as per my original post.
The Apple Dual-Link DVI adapter is plagued with issues and has a lot of faults, so I'd rather avoid it. It is also significantly higher priced than the above option of DP.

Blank/Black screen when connecting to server

When I try to use ARD to connect to my XServe all I get is a black screen. For some reason though using VNC from a PC works fine. Any thoughts?

Just to follow this up, found that having jumb frames enabled was causing this. Change the frame size back to 1500 and it works fine.

Black screen when connecting iPod to Mac

Black Screen when connection apple TV 2. Gen to my TV via HDMI an over a Doulby Suround System (Sound is OK)

Dear Apple Comunity,
at first i want to wish all the best to the family and close friends of Mr. Jobs. It is a sad loss for all of us.
To come back to my topic:
I connected my apple TV set by HDMI to my Yamaha Doulby Surround System. When i try to use it then one in a while the screen stays black but i can hear the sounds of using my apple TV. I guess that indicates that the signales went from the apple TV to the Yamaha System but somehow the visual informations don´t reach my TV (and yes, i pluged the HDMI-Cable from the Yamaha to the TV-Set).
It just happens once in a while and i don´t know what to do about it. It´s pretty inconviniend that way.
The only way to get it back in track is to remove the Powerplug (HDMI doesn´t work).
Any suggestions.
Regards
René Engel
PS. Pls excuse my bad english.

I suspect it's your receiver, connect the HDMI directly between the Apple TV and the TV and use an optical cable to your receiver from the Apple TV for audio.

Error 1604
This error is often related to USB timing. Try changing USB ports, using a different dock connector to USB cable, and other available USB troubleshooting steps (troubleshooting USB connections. If you are using a dock, bypass it and connect directly to the white Apple USB dock connector cable. If the issue persists on a known-good computer, the device may need service.
If the issue is not resolved by USB isolation troubleshooting, and another computer is not available, try these steps to resolve the issue:
Connect the device to iTunes, confirm that the device is in Recovery Mode. If it's not in Recovery Mode,put it into Recovery Mode.
Restore and wait for the error.
When prompted, click OK.
Close and reopen iTunes while the device remains connected.
The device should now be recognized in Recovery Mode again.
Try to restore again.
If the steps above do not resolve the issue, try restoring using a known-good USB cable, computer, and network connection.
Error 1600, 1601, 1602
Follow the steps listed above for Error 1604. This error may also be resolved by disabling, deactivating, or uninstalling third-party security, antivirus, and firewall software. See steps in this article for details on troubleshooting security software.

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- 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.

Yoga 2 Pro - Black screen when on tablet mode

Hi,
2 weeks Yoya 2 pro out of the box, and get a black screen when reaching the tablet mode (back of the lid touching the back of the laptop base).
I try hanged the setting under power management, with no success. When reaching the tablet mode, I get the same result as closing the lid in laptop mode.
I connect my Yoga 2 to a TV through the HDMI and can see the screen and interact with the black screen (not easy to touch the right spot).
My bios is updated and I have Windows 8.1.
Any suggestion???

I found the answer to my problem at
http://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/Yoga-2-Bios-Update-Crash/m-p/1322487/high...
Now that I found that post I do recall the instructions telling me to turn it off manually when I updated the bios earlier this year. However, the current instructions do not mention it at all, perhaps they should be updated?

Why do I get a black screen when i click on a PDF in a web page?

why do I get a black screen when i click on a PDF in a web page? Firefox works as is should.

Hi,
From your Safari menu bar click Safari / Preferences then select the Extensions tab. If you have any installed, turn that off, then relaunch Safari. Try a PDF file.
If it's not Extensions, open a Finder window. Select MacintoshHD in the Sidebar on the left. Now open the Library folder then the Internet Plug-Ins folder. If you see any files such as this:
AdobePDF Browser or Viewer Plug-in
Move it to the Trash, relaunch Safari.

IPod Classic's screen when connecting to ITunes

With my IPod Classic 80GB with displying time on the menu, when connecting(Syncing) to ITunes, where time was displyed on the top grey line like 8:20PM for example, it turns into a meaningless letter 'P'.
If the time is like 8:20AM, no such letter will appear on this grey line.
Is this for everyone's ipod classics? Or only mines stuffed.
No fault on its functions, but curious if this is just a stuff up by Apple.
Your yes/no is much appreciated.
Thanks.

I'm seeing the same here, too. Letter "P" on top of the screen when connected to iTunes.
I will see if turning off the clock in the display or switching to 24hour time works. Hadn't noticed if connected in the AM makes a difference since I usually synch up at night in the PM.
The iPod seems to operate just fine otherwise.

My Macbook Pro has a black screen when running in Bootcamp Windows 7. Since I updated the mac side my windows side now starts up with completely black screen - no prompt, nothing, Cap keys still light up as does mouse and DVD drive seems to run.

Will not show up in safe mode, will not show when started from Windows 7 DVD.
I suspect the Mac update wiped out my PC video drivers but can not think of a way to re-install?
Can see the PC volume from Mac side with files.

Specifically, the posts by Dunsany and valkyr did the trick. I booted in safe mode, uninstalled and deleted the Nvidia driver, disabled automatic driver installation, and restarted normally. I then manually downloaded and installed the previous Nvidia driver for my graphics card (which at the time of this writing was 335.23, rather than the latest which was 337.88), and everything is now bueno!
Two hiccoughs along the way: First, when I tried to uninstall the Nvidia driver the first time, when I restarted I got the login screen (which was a good sign), but it quickly went black again. I powered down, restarted in safe mode again, and repeated the uninstallation process, and it worked the second time. Second, when I started the manual install of the 335.23 driver, the computer played a sound similar to the one for disconnecting a USB device, and the screen went black. I'd seen a lot about trying to increase the brightness (though it hadn't worked up to this point; but if you haven't tried it yet, might as well); I tried it, and it worked! So far I'm back up and running. [/fingers crossed]
Hope this helps someone else!

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
* On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
[[Image:FirefoxSafeMode|width=520]]
''Once you get the pop-up, just select "'Start in Safe Mode"''
[[Image:Safe Mode Fx 15 - Win]]
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.
