X11 term disappearance

Since I upgraded to Leopard on my Mini I no longer can get an X11 terminal to surface. As a consequence I can't run Open Office either.
ps -A | grep X11
results in an indication that there is a terminal but it isn't visible. What's not happening? I don't have this problem on my PowerBook.

I'm not sure if this is exactly what's happening to you but there is a bug (acknowledged by apple) introduced by one of the point updates which sometimes prevents X11 from launching. reinstalling the latest version of X11 from
http://xquartz.macosforge.org/trac/wiki/X112.3.0
usually fixes it.

X11 term won't accept keystrokes

I've asked this over at the Using MacOS X Tiger forum, too, but was advised to post here for better advice. Here it goes:
I launch X11 and then try to type
/usr/X11R6/bin/xgrk2
(where 'xgrk2' is a keyboard map switcher which I've using with OpenOffice.org2.1 on X11 to give me the correct greek accented vowels)
but all I see in the term window is the slashes ////
I have unchecked the Use the System Keyboard Layout option in Preferences in X11, so I am suspecting that I have somehow corrupted my latin keymapping in X11.
Anyone knows how to get me out of this one? Many thanks, people.

I have decided that I must enable Use the System Keyboard checkbox in X11 Preferences for things to work properly.
I now need help to automatically run a binary when running OpenOffice.org2.1 (OOo2.1) in X11. I need the soffice which is called when I click on the OOo2.1 icon to also run a keyboard switcher for english/greek which I must use in order to have the correct accented vowels in greek within the X11 environment.
Until OOo2.0 I just added the following two lines
# launching greek keymap switcher
/usr/X11R6/bin/xgrk2 &
before these two lines already existing in the soffice binary:
# execute soffice binary
"$sd_prog/$sd_binary" "$@"
and everything worked fine. But now with OOo2.1, the last two lines are slightly different:
# execute soffice binary
"$sd_prog/$sd_binary" "$@" &
trap 'kill -9 $!' TERM
wait $!
Notice the " &" at the end of the 2nd line as well as the next two lines that follow. Do they break the functionality that I describe above? Or is there some other reason for which things break? What happens is that the flag window does appear (this is my keyboard switcher) and it _does_ switch between greek and english, but my keyboard layout remains the same.
I have resorted to manually opening xgrk2 (the keyboard switcher) from a separate term window, and things go fine from there. Only it's a nuisance that I can't have everything open automatically by clicking on the OOo2.1 icon.
Tips anyone?

X11 disappearance after 10.4.11 update

X11 app disappeared after 10.4.11 update.
Spotlight can't find it on the hard drive.
Trying to re-install => error message "later version of X11 still installed...".
Thanks for your help

Finally, I've got the solution by re-installing X11 from the original DVD (and not from a downloaded package).
R is now running.

I just downloaded and installed the new iTunes on a Toshiba Satelite of some age. It was just completely reformated and updated with XP. iTunes will not open. The terms page comes up and when I agree it disappears. I have uninstalled and reinstalled.

When I try to read a PDF file, the window opens and then disappears after a second or two. This began after the last Adobe update. I tried accepting the Adobe terms using Eula.exe but that disn't solve the problem. What do I do?

I can no longer read PDF files. The window opens and then disappears after a second or two. This began after the last Adobe update. I tried accepting the Adobe terms using Eula.exe but that disn't solve the problem. What do I do?

Can you open Adobe Reader by itself? If so, try disabling Protected Mode [Edit | Preferences | Security (Enhanced)].

Disappearing X11 terminal window

My X11 terminal window appears briefly before disappearing. I downloaded another version from XQuartz (appropriate for OS X 10.5), but this did not remedy the situation. What do I do to fix this?

Chances are your shell initialization file is issuing a command that exits from the shell, and when that happens, the X11 xterm session goes away.
Either disable your shell initialization file, or examine it closely to see if there is something causing your shell to exit.
.bash_profile
.bash_login
.profile
/etc/profile
are likely canidates, assuming you are using 'bash' as your shell (the default).

Firefox4 on ubuntu, after awhile when I click on bookmarks and then move the cursor down to a bookmark, the list of bookmarks disappears. A stop and start of firefox4 fixes the problem but what is the long term fix?

I upgraded to 4 and I noticed that after 4 has been up for an hour or so I click on the bookmarks. I see my list of bookmarks below but when I move the cursor down to select one, the list disappears.
The only way I have found to fix this is to stop and start 4. I can then move the cursor down to select a bookmark. This problem has not occurred in previous versions.
ps.. no '''''delicious''''' installed

No, I see the three areas at the bottom of the Bookmark area that you refer to, but that also highlights an issue. When I want to save a story to my Reading List and click on Share then "Add to Reading List" then go back to look at what is stored in the Reading List, my recently-saved item is not there.
I looked thru the History tab and the Reading List tab and have been in the Bookmark tab. But even when I Save a Bookmark, that newly-saved Bookmark does not show up in the Bookmark area.
But then again, the next day (and actually just in the last half-hour) all of the functionality came back. When I look at the Bookmarks, suddenly, again, all of the Bookmarks that are on my Safari browser on my iMac are now there, and I can now Save a Bookmark.
It keeps coming in and out and that is what is driving me a little nuts.
Thanks.

Terms and conditions will not disappear, it's an infinite loop! I just want to download YouTube app!

I have tried to download youtube and minecraft lite off of the app store on my iphone 4s and when I click on install, a window pops up saying, "Our Terms & Conditions have changed, please read and agree...." with both an okay button or a cancel button. Anyway, I click okay and I agree to it and it says, "Youtube will now be installed" with an okay button. After I hit okay, the Terms & Conditions window pops up again!!! And it's an infinite cycle until I click cancel, in which case it won't install it! FRUSTRATING!!!!!!!!! FIX IT APPLE!!!!

I'm having the same problem. I check the box, click AGREE to the terms, and the pop up comes up indicating that it has changed and I go through the cycle again. I tried to go through iTunes to update the terms, but nothing. Just happens to me in the AppStore. Bad thing is that I am trying to download a FREE app.
Let's get it fixed Apple.

Itunes has disappeared from my mac, how do I restore it in layman's terms only please?

Internal Hard Drives Disappeared, Finder Memory Problem

Hello Helpful Folks,
I recently installed an addional internal Hard Drive, and an additional 1GB SDRAM. This worked great for a day, but the next morning, after powering up, system was extremely sluggish, and after much deadline-induced impatient problem solving, has gone from bad to worse (system refuses to acknowledge existence of internal Hard Drives). I apologize in advance for the length of this post, but as
the devil is in the details, I figure too much info is better than not enough.
Following is a breakdown of my system: AS IT LAST WORKED; RECENT UPGRADES; and MY LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE. Please don't interpret my all caps as shouting, just trying to organize this post for better clarity.
System is dedicated to Video Editing with FCP 3, running under OS 9.2.2. System is "off the Grid", i.e. no network, no internet, no printer, no gaming devices. System was purchased new in July 2001, by a friend. At one point I know this system had an Airport card, which was removed prior to my purchase in 2003. I can't remember what else it may have had installed in its history, but here's what it has now:
SYSTEM AS IT LAST WORKED:
**bold items are upgrades Original Owner or I installed with no apparent problems**
Power Mac G4 "Quicksilver" 2001
867 PowerPC G4, 256 L2, 2MB L3
-1 Stick "ValueRAM - KVR 133 x 64 C3/512" in PC 133 DIMM slot **
- "Virtual Memory" was turned off years ago due to conflict with FCP 3
-2 empty DIMM slots
-1 60 GB internal HD (Maxtor Ultra ATA/100), 1 partition, formatted HFS+, jumpered as "Master" on Internal ATA 2 ID=0 (which as I understand it is ATA/66 speed)
-1 Pioneer "Superdrive" DVD-R/W/CD-R/W on Internal ATA 0 ID=0
-NVIDIA GeForce2 MX with 32MB SDRAM in AGP Slot, feeding a 17" Apple Studio Display.
-PCI Display Card "formacGA7" - not attached to any external device, not sure what its intended purpose is.**
-3 Empty PCI Slots
-OEM Keyboard attached to Monitor's rear USB port.
-Microsoft 3 Button Wheel mouse with "IntelliEye" (wheel is 3rd Button) connected to Keyboard USB port (right side).**
-2 OEM FireWire (400) ports
-2 OEM USB (1) ports
Peripherals that have worked in various configurations with this system over the past 3 years:
-3 OWC Mercury Elite ("Oxford Chipset") Externally powered, External FireWire(400) 200GB Hard Drives, 1 partition each, formatted HFS+, daisy-chained to either of the FireWire ports.
-1 Canon GL1 MiniDV camera, attached either to the other FireWire port, or to the last drive in the chain, depending on my urgency/laziness factor. BTW, FCP 3 has worked flawlessly controlling this Cam for logging and Batch Capturing.
Applications on System Hard Drive that I have OEM CDs for:
-OS 9.2 - (I think I remember that OS X was removed from system due to conflicts shortly after original purchase)
-FCP 3
-DiskWarrior (version unknown, purchased from Alsoft in 2003)
-OWC Intech Hard Disk SpeedTools ver 3.5
Other CDs I have:
OEM CDs for Power Mac G4:
-Software Install, OS 9.2, CD vers 1
-Software Install, OS 10.0.4, CD vers 1
-Software Restore, OS 9.2 & 10.0.4 CDs vers 1, Discs 1-4 of 4.
-OEM Apple Hardware Test; Power Mac G4, SW vers 1.2.1
Applications on system Hard Drive that I don't have CDs for, that I rarely use, but I'd like to keep:
-After Effects 5.0
-QuickTime Player 6.0.2
-Toast Audio Extractor 1.1
-Toast Titanium 5.0.2
Applications on system Hard Drive I use if my wife is busy on our Windows XP machine:
-Photshop 6.0
-Microsoft Word & Excel
# of other Applications on System Hard Drive I either don't use or may be integral to the system: 260
# of Control Panels:
-Enabled: 34
-Disabled: 0
# of Extensions:
-Enabled: 174
-Disabled: 0
note: a number of the applications and extensions are for AOL, Quickbooks, Microsoft Money and the like, as well as other things I don't use (Airport, USB printers, Networking, etc.)
Smart things I did:
-Regularly made backup copies of my FCP projects to the external drives.
-Bought a copy of MacDrive so I can see what's on my External Drives on the XP machine.
-Printed out System Profile before I installed upgrades.
-Thoroughly searched this discussion board for and gathered as much info as I could before upgrading.
Dumb things I did:
-Made a copy, but not a clone, of my System Folder to one of the external drives when I first got it.
-Didn't keep any sort of separate log of what's on the External Drives.
-Never ran any sort of Disk Maintenance, even after one of the Externals crashed (DiskWarrior saved my butt on that).
-Ignored some of the advice on this discussion board.
Really dumb thing I did without even realizing it:
Captured all media for a rush job onto my internal system Hard Drive, as well as storing and using massive jpgs for the same job on that same drive...
Which led to painfully slow rendering times, and crashes caused by "Error: Out of Memory", which I interpreted as "Must buy more memory" and not "must make sure I'm not trying to edit media stored on system drive, especially with massive jpgs that I should reduce"
RECENT UPGRADES:
Here's what I did, and how I did it:
Turned off system, disconnected all External FireWire Devices, disconnected Monitor, opened case, touched various metal parts of case and power supply to discharge any Static, unplugged power cable.
-Installed 2 512MB sticks of "Lifetime" PC 133 SDRAM; total System RAM is now 1.5GB, all 3 DIMM slots now occupied.
-Installed 1 Maxtor "DiamondMax" Ultra ATA/133 100GB Hard Drive (8 MB buffer) as "Slave" (no jumper) in top of U-Carrier above System Hard Drive; attached to middle of original Apple ribbon cable, attached available power plug.
Taped spare jumper to inside of empty drive bay, noting origin and date. Did NOT push PMU button. Carefully closed case. Reconnected Monitor, did NOT reconnect any FireWire devices. Powered System on, but did NOT perform PRAM reset.
I don't remember the exact order of what happened next, but I think: System booted up normally, a window popped up saying a new drive had been found, would I like to intitialize it?, which I did as Mac OS extended, and then named. If I was instructed to restart, I did so, otherwise did not. Clicked on "about this Mac" and saw that it now showed 1.5GB RAM. I then went about moving Media/Render files off the System drive (and one of the Externals) onto the Internal Drive, with a combination of FCP's Media Manager, and dragging from the Finder. After files had copied, dragged Media/Render files from System Drive to Trash. Opened FCP project, had FCP re-link to new locations of missing files. Saved, closed, and re-opened project, set Capture/Scratch disc to new internal Drive. At some point I changed FCP's Memory Allocation from whatever it was to 512000KB Minimum, and 900000KB Prefered (and I hope I got all those zeroes right). Did NOT restart after changing Memory Allocation, unless a window popped up instructing me to do so, in which case I did. Re-opened my project, rendered a few thing at a noticeably increased speed, saved everything, emptied the Trash, shut everything down, and called it a night as it was 4:30 am.
A few hours later, I plugged the MiniDV and an External Drive into the FW ports and powered up the System. It was behaving extremely sluggishly. I would click on something, the pointer would turn into a wristwatch (sometimes with the minute-hand moving, sometimes not) and like an actual minute later, what I'd clicked on would open. All three drives were on the desktop, still had their files, and "About this Mac" still showed 1.5GB total Memory. So I powered down, disconnected the FW devices, waited a bit, and powered back up. Same sluggish response. I tried to open my FCP project file, and instead got a Window that said something to the effect of "The Application associated with this document could not be found". I think I tried to open FCP from the Applications folder on the System Drive and got the same message (I'd only had 3 hours sleep, no coffee, my client had died, and his family was coming for whatever I had in a few hours).
LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE
Panic had set in, which never solves anything, so I don't remember what order I performed which tasks, between searching for clues in this forum, and convincing myself that that would be faster than trying to compose a question, waiting for a response, etc.
The first two things I did, and I can't remember which I did first (both from Keyboard Commands during Restart):
Rebuild Desktop
PRAM Reset
Neither of those solved the problem, so I continued.
I tried restarting without extensions.
I would get errors that said something like "Not Enough Memory to Open Finder".
I tried booting from Disc 1 of the Software Restore Disk, which only wanted to destroy my data.
I tried booting from the OS 10 disk, with the same result.
I was finally able to boot from the OS 9.2 Software Install Disk, and actually saw both internal drives on the desktop, and the 1.5GB RAM in About this Mac. I tried to allocate more memory to Finder, but was informed that "Cannot Perform Requested Operation. This operation requires versions above 8.0".
I think at this point I decided that I must have too many extensions, and started disabling ones I thought irrelevent to my cause (mostly anything that said "AOL", "Airport", "Ethernet", "Printer", "Modem", "Speakable", and a couple things called "Open TPT".
It gets worse. Then I decided to turn off some "unnecessary" things via the control panels, but somehow managed to disable the control panels themselves: AppleTalk, DialAssist, File Sharing, Modem, Mouse (as I saw that Microsoft Mouse was among the others), Remote Access, Speech, USB Printer Sharing, and possibly TCP/IP.
That certainly didn't help anything (though upon restarting from the OS 9.2 Disc I was able to see the extensions and control panels in their respective "Disabled" folders in the System Folder). But I still wasn't able to get more Memory to Finder.
So, I decided a few more PRAM resets might help, which succeeded in making both Internal Hard Drives disappear. I tried booting up from the DiskWarrior disc, but even the Mighty DiskWarrior couldn't find the drives. I performed the longer, in depth version of the Apple Hardware Tools tests, which reported that everything's fine (including the new RAM), but made no mention of the Hard Drives at all. The deadline having long passed, I shut the system down. I read through more posts and tech articles, etc.
I searched my External drives with MacDrive on my XP, and found the drive that has the copy of my System Folder (which shows all extensions and control panels as enabled); not sure if the Quicksilver will boot from that, I don't know what the Keyboard command for booting from a FireWire drive is (if there is one) and the drive itself only has 900MB of free space.
I can't find any reference to Internal ATA drives anywhere in the MacDrive documentation; if it was possible I'd put them into the XP, get the files off the Mac drives, reformat them and install OS9 from the Discs.
This is where I am now:
The Quick Silver is still powered down. I removed the Microsft mouse and replaced it with the OEM Apple mouse. I opened the case, and removed the PRAM/Backup battery (manufacture date: July 2001). Couldn't find my voltmeter, so took the bat to Radio Shack and bought a new one. Had the Radio Shack guy test the old one: it showed 3.69 volts still. Have not installed the new battery yet. The case is still open, waiting for any advice any of you might have to offer.
Thank you all so much for your patience in perusing and pursuing this.
Sincerely,
Patterson
Power Mac G4 Quicksilver 867 Mac OS 9.2.x 17" Studio Display, 512MB RAM

Thank you Rodney and John,
The jumpers are correct for both Maxtor Drives.
Rodney, you are correct in that the initial problem (slow rendering/"out of Memory" crashes) was caused by my not realizing I'd stupidly captured several GBs of media to my system drive, and not checking which drives those files were on (as I'd assumed I'd put them on one of my external media drives) once that problem presented itself.
Before I'd determined what I'd done, I bought the extra RAM. After I'd found the media files on the System Drive, and saw that my dedicated media drives were too full to easily move them, I decided to buy an additional Internal drive so that I could:
-Move the Media onto it relatively quickly and finish my urgent project.
-Juggle all my media into a more organized fashion for archiving (as most of my projects are on-going long-term affairs)
-Wipe it, Partition it, and clone my System Drive onto it, as a spare bootable drive in case my OEM System Drive failed.
Copying the Media files onto the New Drive and moving the System Drive's Media files into the Trash worked great: huge improvement in Rendering, etc.
Before shutting down for the night I Emptied the Trash, and was pleased with the amount of space I'd freed up on the System Drive.
My guess is that the System Drive was terribly fragmented, having been subjected to intense use over the past 5 years without any sort of Drive Maintainence, and deleting that massive amount from it in one shot caused my extreme system sluggishness upon Startup the next day.
My subsequent lame attempts to solve the sluggishnes ultimately resulted in my losing access to both drives.
Today, I replaced the Backup Battery, pushed the PMU, re-attached the AC, and Powered Up with the case open as per your suggestion.
It was trying for a few minutes (the gray screen went black at one point, and then returned to gray) before presenting me with the flashing question mark.
There was, however, a quiet but distinct "buzzing" sound that would alternate: 1 sec "buzz", one second silence, one second "buzz", one second silence, etc. coming from the drives, even after the "?" appeared.
I powered down, removed the Ribbon and Power Cables from the new "Slave" drive, and powered up again, with the exact same results.
I powered down, removed the Ribbon and Power cables from the original "Master" drive, reinstalled the Jumper on the New Drive as "Master", plugged the End of the Ribbon and the Power cables into the New "Master" drive and powered up. The screen went to the "?" within 20 seconds instead of 4+ minutes, and no more "buzzing".
I put the Apple Hardware Tools Disk in, ran the "long" test, and everything came out fine.
I have to abandon this for now, but thanks again for your previous advice, and any more you may have!
Cheers,
Patterson

Why do google search results reset to match the search bar terms when i use the back button?

Since the update to FF 23, the list of Google search results clears and the on-page search box is reset to match the address bar search box when I hit the back button to re-view the results list after checking a result.
To see this issue for yourself, set your search provider to Google and make sure Instant is on. Type a search term into the search bar and press enter. A google page appears with your results list. Now, change your search terms or conduct a new search directly from the google page (without using the FF search bar). Click on the first result in the search list, then click the back button to return to the search results so you can check a differest result. As FF goes back to the google page, it will reset the on-page search box to match the FF search bar (although you were no longer on this search) and all search results will disappear, replaced by the message "Press enter to search". Pressing enter reconducts your old search, not the one you were on.
This is incredibly maddening since searching for something requires frequent use of the back button to check through the list of search results, and then frequently trying the search again with slightly different terms. Although it sounds like a Google issue, it did not occur on the old firefox and has me wanting to revert. I tried to revert to the old search function via the "keyword search" addon, but this did not fix my issue. Is there a way to force FF to go back to the actual google search page I was just on instead of conducting a new google search from the FF search box when I hit the back button?

In Firefox 23 versions and later the keyword.URL pref is no longer supported and it is no longer possible to specify the search engine for the location bar via the keyword.URL pref.<br />
The search engine that is used on the location bar and on the about:home page is the search engine that is selected in the search Bar on the Navigation Toolbar.<br />
Current Firefox versions do not update the about:home home page until you refresh the page (future versions will do this automatically without a refresh) and that is what happens if you use the Back key.
You can install the Keyword Search extension to specify with search engine to use for the location bar and which search engine to use for the about:home page via the Options/Preferences windows of this extension, accessible via the about:addons page.

X11 there but not there

Hi,
I thought I had x11 installed but I cant find it and an app that I am trying to use cant find it. I downloaded the installer from Apple, but when I try to install it, it says that newer software already exists. Im trying to use Darwine.
Thanks
Josh

You cannot download an X11 installer for Tiger. The version you want is already on your Tiger DVD. Insert the DVD into the optical drive and when the window appears double-click on the Optional Installs package. Deselect all but the X11 package and click on the Install button.

TS1717 iTunes "Terms and Conditions Have Changed Before you can proceed you must accept the terms and conditions" is on an infinite loop. No matter how many times I agree, when I go to update my apps the terms and conditions have changed link reappears.

Can anyone help me? Suddenly (i.e. just a few minutes ago) this problem has appeared. I attempted to update two apps on my iPad. The Terms and Conditions agreement comes up, I read the terms and conditions, I agree to them, I click AGREE, it disappears, I reclick on update and the Terms and Conditions agreement appears and we start the mobius strip all over again. I tried to see if it was just on my iPad by trying to download a new app on my iPhone. same problem. Anyone have advice on how to resolve this issue? Oh, and of course, Apple has declared my two new devices to be out of warranty and want me to pay to ask how to fix a problem caused by their own software. Lovely. so helpful. Hey Cupertino ... are you paying attention? I might start tweeting about this.

I updated the software on my iphone4 tonight and ran into this same endless loop - "itunes terms & conditions have been changed" - go to itunes, aceept - back to the "T&C have been changed message" with no ability to do anything in the app store until I accepted the new terms.
While not a very direct solution, I was able to finally accept the terms in a way that seem to register with apple by making a purchase through iTunes on my computer. This forced me through updating my payment information and updating my iTunes software to the latest edition (which I had not yet taken the time to do). After doing both of these, iTunes took me through the terms & conditions on two separate pages, but ultimately allowed me to purchase my song. Once I completed these steps, it fixed the problem on my phone, so now I can update my apps and download new ones without running into that loop.
Hope this helps!!!

TS2755 Messages disappear in inbox. When I close out messenger entirely and reopen it, they appear. Also, if I only have one message unread in my inbox and I open up my messenger it automatically opens the unread message. Very frustrating....Please hel

I have an iphone 4s, OS 4.1.1. I am having issues with my messenger. When I have a message open I will see a new text come through and then it disappears. I have to close out of my messenger entirely and reopen it. Once I reopen the message the text reappears. Any suggestions? Also, if I get a new message and there is only one unopened message in my inbox and I open my messenger it automatically opens that message. Any way to fix this so that I decide when I want to open a certain message?
Thanks in advance for your help!
Jen

There are several possible reasons that messages seem to 'disappear'.
There are two types of email accounts: IMAP and POP. See https://support.mozilla.org/en-US/kb/glossary-terms-including-types-accounts
If you have a POP account and are accessing the mail on more than one computer or smartphone, whichever device reads (downloads) the message first will have it locally, but it will no longer be listed or available on the other devices.
If you have an IMAP account, the message stays on the server, but if one device (user) moves or deletes the message, it will affect the view on all devices. So, for example, if you are using your smartphone and take some action on an email, when you get back to your computer, it will reflect that same action (but you might not have realized what caused it).
Sometimes the index of a mail folder (.msf) will get corrupted. If you right click on the name of the folder and select Properties, a 'Folder Properties' window will open. Select 'Repair Folder'. This may take care of the problem.
Another, less likely, reason for messages not to show up in your inbox is having the preference set to show only unread or recent messages. Then once you read them they seem to disappear.
If you are still having problems, please look at the following items and respond with the information.
1) What operating system do you use (Win8, MAC, Linux, etc)?
2) Are you using IMAP or POP?
3) If your mail server has a browser interface (web mail access such as mail.google.com), do the messages show up there?
4) Right click on the folder in question and select Properties.
a) Number of messages?
b) Size on disk?
5) Left click on the account name; View settings for this account; highlight Server settings;
What choices are marked under "When I delete a message"?
6) What, if any, antivirus program do you have installed?
