Hi,

Yes, I've several issues with FFB on my Gnome desktop Linux (Ubuntu 10.04).

    I have the following problems
  • Q: Using Linux and the Gnome Desktop a white bar appears at the bottom of the screen, prohibting the use of the chat. (A: This is a known issue with Gnome and the Java JDesktopPane (InternalFrames) in that Gnome renders a toolbar inside the application. The only workaround at the moment is to use a different Desktop (e.g. KDE) or Windowmanager. )
  • Java uses lot's of ressources. Is there some memory leaks ?
  • I've a problem with sounds. There is a delay between actions and sound. The delay increase over time. The more strange is that I can still hear FFB sounds after I closed the client.

Due to those problems, I didn't start playing with the FFB client (I was just spectating some games). Has those issues been solved ?

java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01, mixed mode)

I'm running Ubuntu 10.04, but I'm sticking to LRB4 as long as possible, so I haven't played any FFB games. Does the sound-delay also happen while spectating? I have no issues with sound while spectating. And for the white bar; You can still use chat, by clicking in the white area to the right, and typing in your message, only thing is that you can't see what you have typed.

Hi,

the problem with the white bar at the bottom can't be solved by java. It is a problem of the Gnome Desktop and hasn't been fixed by now (i will try the newest java version, when my VM is set up in a few minutes). Perhaps a checkbox would help, which increases the height of the window optionally by about 30px. Gnome users could enable this to get a better view on the window.
There are no leaks in java (one main difference to c++). The garbage collector (gc) is running all the time and frees all space from resources, that are not referenced at this point. So the amount of memory seems to be used by the ffb itself. Using 64-bit increases the amount of used space in comparison to a 32-bit OS. On my 64-bit Windows a game takes about 120mb of memory.
I have never experienced sound problems. Perhaps your driver is configured wrong. (doesn't help, but perhaps knowing, that this is odd, helps, too)

Greets,

I heard something about that white bar being a gnome toolbar panel or something like that which Gnome adds to all windows to show information. I did a google for "remove gnome toolbar" and found several ways to do it, maybe you could try something like that?

I don't have an ubuntu machine to test this with, so cannot help you with the issue.

As for the sound, i heard someone else having problems with sounds when running linux, this is because different OS handles the java-sounds differently and coding for them all specifically is hard.
As far as i know, it works for most users. If you try to disable sounds, does this affect your performance?

The pros of using Java is that it runs on most OS:s, the cons is that it might not run perfectly.

There's a work-around in my blog, if you are running Mint/Ubuntu/Gnome all you have to do is switch window managers. It's not hard, and it's easy to switch back and forth as needed.

Hi,

it is not that easy, it seems. I can't remove the toolbar at the bottom using the hints from the threads found by google.
I tried to remove the whole gnome-panel, but this doesn't work either - the bar is still there. (don't try this, prevents a lot of trouble)

Greets,

Using another desktop manager is simple and maybe for now the only possibility to work with the "feature".

Switching window managers for one application is a big no-no and shouldn't even be considered seriously...

I have problems with sound, too. It could be a "delay" like mentioned, but the way I experienced it, it feeled like some sounds were skipped and others repeated. Probably a problem with the buffer. Then again, maybe it's just a misinterpretation and it is, in fact, delay. I spectate games with the sound off, but it's a pain =)

The second problem is related to sound. If you turn off sounds in-game, then the game won't freeze. Alternatively, if you follow the instructions mentioned in the following thread, then you can play / spec with sound. Smile

Installed Kubuntu

Changed the script to

cd /usr/lib/jvm/java-6-sun/jre/bin
sudo mv java java.bin
sudo touch java
sudo chmod +x java
sudo nano java


#!/bin/bash
padsp /usr/lib/jvm/java-6-sun/jre/bin/java.bin "$@"

Works fine now.

Thanks for the help Smile

I am experiencing the bar along the bottom and am not a Gnome user. (I am using OpenBox)

I do not have any other window manager installed and have no desire to install a Desktop Environment like KDE.

I guess you're screwed then.

I installed XFCE and the client works fine. Sound is a little screwy but I can manage. It's really a minor pain to endure in order to play BB!
