Qt 4.7 on Ubuntu Lucid not loading JPG Image Plugin

I’ve written a photo resizer program, which can be found here on Source Forge.

I’m now porting the program to Linux, which is no issue except when it comes to getting it to run on a system where the development environment is not installed. I’ve installed the following packages: libqtcore4, libqtgui4. The program runs fine, except that JPG support does not work. PNG works fine.

The image plugins are there in both usr/lib/qt/plugins and usr/lib32/qt/plugins. Although the list is not the same which is strange.

usr_lib_qt4_plugins_imageformats
usr_lib32_qt4_plugins_imageformats
Report Lib Paths And Image Formats

So why won’t JPG images load into my program?

Ubuntu 10.04 – Nvidia driver install issue

Update: Restart to clear the error below and then install the [recommended] driver. All is well as far as I can tell.

Using Ubuntu 10.04 LTS.
Zotac GeForce 9300 Motherboard

attempted to install the [recommended] choice and it failed.

With a previous install, this worked, but then system failed to start graphics when it rebooted. But that system used to have an AMD video graphics driver installed, so I reinstalled the entire system and now this occurs.

How can I clean out the “archives” and try this again?

Ubuntu 10.04 – Problem playing DVDs

Update:

  1. Use regionset to set the region code if it’s not set.
  2. Use gxine, which is a more robust dvd player application.
  3. Now it plays most protected DVDs as well as unprotected ones.

Just installed Ubuntu 10.04 x64 on a mini-ITX system and would like to play DVDs. I’d like to use this as an entertainment system.

It plays non-protected DVDs just fine.

I have followed instructions here:

https://help.ubuntu.com/community/RestrictedFormats/PlayingDVDs

Including the part about chmod chgrp in the trouble shooting part.

But protected DVDs give me this error:

MoviePlayer Error

Here’s the package manager showing what’s installed that might be relevant:

Any clues about what might be wrong?

Thanks,

AlienFX Software – Fails on Vista x64

Summary

An Alienware Desktop from May 2007 has been upgraded to run Vista x64. At this time I cannot find a working version of the AlienFx software to power the AlienFx Lighting Interface and the desktop is dark. Since the upgrade to Vista x64, the lighting has worked since the settings were saved inside the AlienFX interface, but after a memory upgrade to 8GB, the AlienFX lights are now dark. I need to have the system lighting working on this system. The system was purchased with a 4 year warranty and so is under warranty until May 2011.

While Alienware did not support Vista x64 at the time the system was purchased, they have supported 64-bit operating systems since shortly after the system was delivered.

QTcpSocket – Unable to Connect

I’m doing a lot of programming with the Qt toolkit using Qt Creator.

In doing network programming, I can’t get a QTcpSocket to connect to a website.

Here is an example program. The connect will not call back the routines indicating that the connect either succeeded or failed. The program is based on this Qt Sample.

Can someone help with the problems.

TcpConnectTest

Fill in a website and click connect. Watch the output for debug messages. The completion slots are not called.

I’m using Qt Creator 2.0.1 with Qt 4.7.1.

TcpConnectTest zip file of the sources.

Thanks,

Firefox Sync – Fails to Transfer Everything

Update: My conclusions were wrong. The sync workaround doesn’t work. See end.

I’m using Firefox Sync on 3 systems. Recently I added some bookmarks on one of the systems that were not propagated to the other systems. At first I checked FireFox  support and there is a long list of things to check. After checking a few things, I decided to do a test rather than going through the rest of the checks on that page. I did disable the plugins – long lists of Java Consoles of various versions – and that made no difference. What I found out when I did a test was that some changes are propagated and others are not propagated. Here is the test that I performed and here are pictures of the results.

Using Bazaar – First Steps

These are the things I want to do with Bazaar. I have a network of Win Vista, Win 7 and Ubuntu systems. Click on any picture for a larger view.

1 – Create a project with collocated repository.
Must do this manually due to the bug in creating collocated repositories but it seems to work by using the All command dialog and colo-init.
