Ncurses won't show any output nor accept input (SOLVED .sort of)

Hi
I have an elderly application (PB/PG for Linux) that builds and runs fine on other distros than ArchLinux (AL). When I build it on AL it builds fine, meaning that the include files and the library are found. When I run the program it does not show any output on the screen and it will not accept keyboard input.
I must admit that I am somewhat at a loss as to what could be wrong, so any help will be much appreciated.
Have any of you experienced this (or a similar) problem? And how did you solve it?
Regards,
Bent
EDIT 2007-12-04: The root cause of this problem had nothing to do with Ncurses whatsoever. I have found another tree to bark up. Sorry for the inconvenience.

So rather quick addition.
I just played with the AccelMethod option in /etc/X11/xorg.conf.d/20-intel.conf and found that this only occurs when it is set to "uxe" or "glamor" changing the setting to "sna" does not result in this problem.
I had originally changed this setting from sna due to font rendering issues. I'll leave it as sna for now and see if those same issues still exist.
Marked solved, but may not a good solution if font issues with sna are still present.

Won't show any real instruments or vocals in the project.

My GB won't show any live vocals or live instruments tracks. I can hear them, but cannot see them and I can't scroll downwards to view them.

Yes. But I solved the problem. For some reason all the live recording tracks would not show. I created a new "live" track and suddenly they all appeared. Some wierd glitch.

TS1398 After updating to iOS 7 my iphone 5 won't show any wifi networks or connect to any wifi even after resetting the network connections. HELP!

After updating my iphone 5 to iOS 7 my phone won't show any wifi networks or connect to any. I reset the network connections and still nothing.

I Just found it on the apple site, it arrived on a cd a few days later and worked just fine again.

IT shoulldnt erase everything, bt it might, so back up just in case
should you loose everything, then i have some tips on moving stuff fromyour iphone/ipod to the computer

Apple TV 3 won't show any networks

I have a Apple TV 3 and a IMAC and a Macbook pro and a Apple wireless router…I can connect using my iPhone,iPad and all the computers with no issues but the AT3 will not stay connected, it will either be connected and work for 5-20 mins and stream just fine and then lose connection and then I go to network and Wi-FI and it will not show any networks at all. I've done all the steps as far as a reset of the AT3 and a restart of the AT3 also a restart of the apple router along with the cable modem. It worked perfectly fine with no issues on 28th of August 2014 and I went away for the weekend and came home to a non working device. I'm losing faith in my AP3 I may have to change to a amazon fire box instead. I hope it's something simple, I haven't updated anything and everything is up to date my airport utility and my apple tv 3.

It won't show any of my artwork... PLEASE HELP!

Anyone know what I can do?
I manually put all the album covers in each song and it won't show on my Ipod nano..

You should be able to get to it whenever you hook up your Ipod. Go to Options on your Ipod whenever you update it next, and tell it to update all your songs, instead of those you just added. That should fix it.
But if that doesn't fix it, I think there might be a button that says to update artwork every time you update your Ipod.

Iphone won't show on computer nor itunes.

Hey everyone, I've looked around for threads on this for a few days now but either nothing was worked or it was very outdated and still didn't work.
To the point, my cousin bought a new iphone 3g and as a gift he gave me his iphone 2g. It worked fine but had all of his information as he didn't do anything to it but give it to me. I assume it has the newest firmware and what not as he was using it about a week ago. I plugged it into my computer but it didn't show on my computer or itunes. I installed the new itunes and while doing so tried to restore (Sleep + Home) and now it's stuck in the USB wire pointing at the Itunes symbol.
So now it won't turn on past that last notice and still won't show up on my computer and itunes. I've tried restarting, reinstalling, restoring, everything that's pretty common at least and still nothing. The phone doesn't show up in the Device Manager either and I've tried 2 different computers and 2 different wires. I'm getting sad at this point as i want to use it! No jailbreak or unlock that I know of also if that matters. If i left anything out please let me know.
Someone please help!
Thanks in advance,

i've had the same problem as narcky: screen shows usb cord with arrow pointing to itunes symbol. i've deleted and re-installed the latest version of itunes, no luck. this happened while i was trying to download the latest version of software for the iphone. i've even tried searching for the iphone in the list of usb drivers and all i get is the recovery iboot, which i dont even know what that means.also tried pressing home button and power button at same time, screen still shows cord with itunes symbol. i've tried everything, nothing seems to work. HELP?

ITunes won't show shared libraries nor will it show iPhone as a device

This is baffling me and I would welcome some assistance. ITunes doesn't show any Shared Libraries/Devices
1. iTunes will not show 2 shared libraries that can be seen by another computer (PC) running iTunes on the same home network
2. Using my iPhone I cannot get the Remote app to work; iTunes doesn't seem to recognise my iPhone, although they are both on the same network (verified)
3. When running 'Bonjour Browser' I can't locate "cciphonethings.tcp" as per the 'Things' support site for iPhone/iMac sync
4. iTunes will sync OK with my iPhone when I place the iPhone in it's cradle
I've followed the advice in Apple support and also followed the checks suggested by the Things support site. I've also reinstalled iTunes. No change.
Thanks in advance.

Hi,
To answer your question, the cpu speed is 550MHz.
Thought so. It seems like PowerBooks from about that era (550, 667) are the most likely to have this problem. I've never seen any definitive explanation, though. If I had to hazard a guess, I'd say it's a combination of hardware and software and how iTunes interacts with the CD drive.
One thing you could do is send a bug report to Apple via their online form.
best,

Obm-xdg won't show anything in the Openbox menu [SOLVED]

I put the code:
<menu execute="obm-xdg" id="obm-xdg" label="xdg"/>
in ~/.config/openbox/menu.xml just like it says to do universally. It does not show any menu. Every other menu item in the file works. I can edit them and they change. obmenu can see the entry. gnome-menus is installed. obm-xdg works from the command line. Why does this not show anything in the menu?
Last edited by skottish (2008-11-06 05:27:03)

Make sure you add the menu id to the root-menu list at the bottom of menu.xml:
<menu id="root-menu" label="Openbox 3">
<separator label="Applications" />
<menu id="obm-xdg" />
<menu id="apps-accessories-menu"/>
<menu id="apps-editors-menu"/>

Event in FCP won't show any of the media anymore?

So I don't have a million projects and events showing up whenever I open FCP, I have created a Hidden Final Cut Pro Events File where I store events and projects when I'm not using them (on an external HDD). When I relocated an event and project to their orignal places (Final Cut Events or Final Cut Projects) they show up.
I've just reccently done this again, and in no time my project showed up but I had to close FCP X and reopen to get the event to show up. And after it did, none of the media showed up that was in the event - if this wasn't a problem before why it should it just randomly be a problem now? So now the clips all say the same thing: Missing Event... But the event is there! Just without any of the orignal media.
I know there's been all sorts of problems with reconnecting media in FCPX discussed before, but I'd appreciate any help and suggestions.

My FF6.0 was fine till it updated (automatically) and then no toolbar buttons.

HT5137 I updated to ios7.0.2, when I double click on home button it brings up an app list but when I hold my finger on an icon it won't show any with a minus sign, is it no longer necessary to close apps?

In ios 7.0.2, when you double click the home button it brings up the icons but won't allow you to show them with minus signs, is it no longer necessary to do this?

Yesterday iTunes worked - today, it acts like it's newly installed (won't show any of my music or playlists) - what could have made it forget everything it knew yesterday and how can I fix it without having to redo all my previous work?

The title says it all. iTunes was working fine last night. I added some more music to my playlists and synched my iPod last night, then shut down. Today, when I start iTunes it opens up a welcome to setup screen and acts like it wants me to answer questions to configure it for the first time. When I cancel out of that, it opens up a normal iTunes screen that's completely empty of music and has none of my custom playlists (all the playlists it does show are empty) and it's asking me if I want to have it search my PC and add media files, as if it's newly installed and that's never been done.
Has anybody seen this behavior before, and is there some simple way I can fix it so it remembers all the stuff it knew last night, without having to start all over again and rebuild all my playlists and stuff?

For general library squiffiness following an upgrade the easiest thing is to restore your last backup, but I guess if it were that simple you wouldn't be here.
Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

Thimble won't show any details on my "broken" code - I can't figure out the problem.

I am trying to add a line for the background image. I followed the thimble example and have tried numerous links, all resulting in a red exclamation mark. I'm not sure what the problem is and nothing happens when I click the exclamation mark.
I also can't save any of my progress because of the error.

Thanks for trying to help guys!
I'm totally new at this so as far as I'm aware, I can't actually get a link because it won't save my progress because of the error? So unless its something else causing the error that won't let me save?
