Sybase Central UI draws nothing but a grey screen

I'm running under RedHat Linux 7.3 with kernel 2.4.18-5. I'm launching the Sybase Central tool and once the UI comes the entire contrents of the window is greyed out. After launcing it numerous times and spending hours, I was able to launch it and have it render successfully only once. Why does this happen? What can I do to correct the problem?
Thanks...

Hello,
Have you blown the dust out lately?
If you boot up holding Option or alt key, how long will it set on that screen without going black?

HT2538 I get nothing but a grey screen at startup

When I turn on my 2008 iMac, I get nothing but a grey screen . . . put in the rescue disk (and held down the "C") and got the Apple logo and the little spinning think, but then to black screen? What to do? What is causing this?

Hi, I downloaded Yosemite this evening. It downloaded fine, it installed fine and then it restarted the Macbook. Now it seems to be frozen. I have nothing but a grey screen with the apple logo and a bar that is half black and half grey. It's been like this for over an hour. Should I worry or is it still working at something? How do I fix this if it's not still working at installing something. Thank goodness for this poor old pc as backup.

Take each of these steps that you haven't already tried. Stop when the problem is resolved.
To restart an unresponsive computer, press and hold the power button for a few seconds until the power shuts off, then release, wait a few more seconds, and press it again briefly.
Step 1
The first step in dealing with a startup failure is to secure the data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since the last backup, you can skip this step.
There are several ways to back up a Mac that is unable to start. You need an external hard drive to hold the backup data.
a. Start up from the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.” The article refers to starting up from a DVD, but the procedure in Recovery mode is the same. You don't need a DVD if you're running OS X 10.7 or later.
b. If Step 1a fails because of disk errors, and no other Mac is available, then you may be able to salvage some of your files by copying them in the Finder. If you already have an external drive with OS X installed, start up from it. Otherwise, if you have Internet access, follow the instructions on this page to prepare the external drive and install OS X on it. You'll use the Recovery installer, rather than downloading it from the App Store.
c. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, start the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
d. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
Step 2
If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. You might be able to start up in safe mode even though you can't start up normally. Otherwise, start up from an external drive, or else use the technique in Step 1b, 1c, or 1d to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
Step 3
Sometimes a startup failure can be resolved by resetting the NVRAM.
Step 4
If a desktop Mac hangs at a plain gray screen with a movable cursor, the keyboard may not be recognized. Press and hold the button on the side of an Apple wireless keyboard to make it discoverable. If need be, replace or recharge the batteries. If you're using a USB keyboard connected to a hub, connect it to a built-in port.
Step 5
If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
Step 6
Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to start up, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can start up now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
Step 7
If you've started from an external storage device, make sure that the internal startup volume is selected in the Startup Disk pane of System Preferences.
Start up in safe mode. Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Post for further instructions.
Safe mode is much slower to start and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
The login screen appears even if you usually log in automatically. You must know the login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
When you start up in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, the startup volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 11. If you ever have another problem with the drive, replace it immediately.
If you can start and log in in safe mode, empty the Trash, and then open the Finder Info window on the startup volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then restart as usual (i.e., not in safe mode.)
If the startup process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
Step 8
Launch Disk Utility in Recovery mode (see Step 1.) Select the startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then restart as usual.
Step 9
If the startup device is an aftermarket SSD, it may need a firmware update and/or a forced "garbage collection." Instructions for doing this with a Crucial-branded SSD were posted here. Some of those instructions may apply to other brands of SSD, but you should check with the vendor's tech support.
Step 10
Reinstall the OS. If the Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
Step 11
Do as in Step 9, but this time erase the startup volume in Disk Utility before installing. The system should automatically restart into the Setup Assistant. Follow the prompts to transfer the data from a Time Machine or other backup.
Step 12
This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a startup failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
Step 13
If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

I am trying to upgrade Mac OSX from 10.7.4 10 .7.5 .But, the grey screen is coming for hours. What should i do?

i am trying to upgrade Mac OSX from 10.7.4 10 .7.5 .But, the grey screen is coming for hours. I pressed the alt key and was taken to options viz. Restart to install MAC again, use time machine. I don't have back-up and so restarted to install MAC again. Can i cancel this now. I want my data to be secure. What should i do?

If you cancel an install there's no telling what state it will leave your Mac in. Let it finish or fail.
Then get a disk, it can even be a pocket drive if it's large enough and back up all your own data.
After that, boot up holding command-r keys into your Recovery Volume.
The screen should give you these choices...
Restore from TM backup
Reinstall Mac OS X

Disk Utility
First run Disk Utility Repair Disk, if you get errors run until no errors reported or reports "the disk cannot be fixed". Then, choose Reinstall OS X.

TS3274 My ipad2 is not responding..I want to restart it but i can get nothing but a black screen with only the apple logo and a small gear icon. It occasionally beeps but no other response. Any ideas as to what may be wrong and what I can do?

My ipad2 is not responding..I want to restart it but i can get nothing but a black screen with only the apple logo and a small gear icon. It occasionally beeps but no other response. Any ideas as to what may be wrong and what I can do?

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

My ipod is 8gb and I downloaded the sims 3 on it and i thought it was done downloading but it's nothing but a white screen. Cant shut it off or try to relaod anything.....please help!! :(

My ipod isnt working at all....nothing but a white screen. I already paid for the application and cant even use it.

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

When updating to the new iOS my ipod died and now I have nothing but a white screen that won't turn off and itunes now doesn't recognize it

When I was updating my ipod touch to the new iOS last night it died and now I have nothing but a white screen. iTunes no longer recongnizes the device and it won't turn off when I hold the power button or when I hold the power and home screen button.

Try:
- 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.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

I just installed the latest update on my iPhone 4 and now it's nothing but a white screen and my computer wont even connect it to my itunes when I plug it in the USB port. What happened?

I installed the latest update to my phone. Half way through it asked to connect to itunes. After updateing it had some type of error and wanted me to restore the phone. After restoring, another error box popped up and said that it could not be restored. Now it won't connect to itunes or my computer at all and is nothing but the black start up screen with the apple logo, or it's just a white screen. What happened?

DFU mode? How do I do that? So far the only thing I can do is hold down both buttons to power it on and nothing is on the screen and it wont reconize on my computer....

Macbook pro acting as if it was on but only grey screen appears.

Hi All,
I am having some rather strange issue with my MBP which is driving me mad.
A couple of days ago I was watching a video and all the sudden the screen started sort of vibrating and then the whole system just froze, had to shut it down by holding the power button.
I then switched it back on, it started booting up but it got stuck at the grey screen with the apple logo and that little wheel spinning, which then stopped spinning and it just stayed like that. Initially I thought it was just the grey screen issue people sometimes get, but I actually noticed that the system is on, or at least is behaving as if it was on (I can change the volume, the buttons are also active, but screen is still the same grey with the logo and wheel).
What I have tried so far:
Safe mode- did not help
Verbose mode with command fsck -fy - found no issue
Booting up from installation disc - it asks me to shut down the computer
Resetting the NVRAM - did not help
Single user mode - did not help
Has anyone got any idea what the problem might be?
Thanks,
Rob

Hi there,
Thanks for your reply.
It says "You need to restart your computer. Hold down the power button until it turns off..."
Below this is the same message in other languages such as French, German etc...a black box in the middle of the screen with I/O sign in the background.
Thanks,

ITunes store won't load. The progress bar freezes at about 50% and I get nothing but a white screen.

I'm running iTunes 10.5 beta 7 but this issue has been happening since I was running 9. One day I clicked on a link for an app I saw on techcrunch and it pulled up in iTunes as being in the UK store. I clicked ok and my iTunes hasn't worked since. I can log into my account but can't access anything in the store or Ping. I've googled this issue and found some similar sounding stories but none of the solutions have worked. I've uninstalled and reinstalled, turned of the itunes store in parental settings and checked "except for iTunes U", I've uninstalled apple aplication suport and installed safari and every other option I have found and nothing has worked.
Sometimes if I let it sit long enough what looks like an unstyled version of the store comes up but is completely unusable.
Just to be clear, this has been happening since before I was running any beta software or OS.
Any help would be greatly appreciated.

Thank you gchin.
I emailed apple support and they got back to me, I did what he said and it's fixed! SOLUTION found- see below.
I said:
"I can't access the iTunes Store. When I click on it the progress bar stops at 50% and I'm left with a blank white screen (no error msg). I have uninstalled and reinstalled, run the iTunes diagnostics (it said all was ok), gone through all of the online help material and I've tried turning off my firewall. Nothing works. I can't sync my iphone either (stops on verifying iPhone so I think it's getting stuck on trying to contact the store). Plzz help."
