Default JDownloader starting without GUI

Hi,

I have jDownloader installed and running on LXDE (Debian Testing). A few days ago, the GUI suddenly became "invisible". Only the splash screen appears.

However, program startup seems to be completed. There is a process "java -Xmx512m -jar JDownloader.jar". Moreover, I can right-click on the JD icon in my dock, click on "close" and - since the gui would display a confirmation window - hit the enter key to confirm. And the icon disappears and the process is stopped.

I could also go to the command line, enter jdownloader --start-download and JD would complete my unfinished downloads.

So it seems to be a problem with painting the GUI. However, this happened out of the blue, without any system updates being performed.

I performed a "java -Xmx512m -Dsun.java2d.d3d=false -jar JDownloader.jar" and run jupdate.jar, but it didn't help.

Any advice?

Cool

If you're using openjdk's JRE I would switch to Sun/Orakel's JRE, otherwise provide an Emergency Log.

Would it be possible to remove that JRE update 26 and install update 29 of the JRE (1.)6?

Well. I update Sun Java via apt-get from the repos. I dont know how to remove update 26 and get update 29 instead. Can you give me a link to more info on that topic?

However. As I said before: I did not update my system before the GUI Window stopped working. So, I cannot blame it on a Java update, as it did work a few days ago.

What if I backup my entire .jdownloader folder, do a clean reinstall of jdownloader and see if it starts with GUI window as before? Do you think that can help in terms of troubleshooting?

Something must have gone wrong with java or jD. You can try a new installation of jD before doing a re-install of your JRE.

I would only backup jD's config folder as it contains your configuration and link data.

backup your config folder (inside your jdownloader folder) and then remove it, so jd can startup with fresh config.
see if that helps

Thanks @Jiaz, @remi.

I did as Jiaz suggested and backupped/moved away the .jdownloader folder in my home dir:

Code:
$ mv .jdownloader jdownloader_backup
After that, started jdownloader, created a new.jdownloader folder in my home dir, performed the updates and the GUI window is back again.

So, it wasn't Java's fault.

Last question: How do I get my download list back?

You need to copy jD's config folder over the new config folder.
