vuze won't open in ubuntu 11.10

Do you see a tray icon? Unity disables tray icons for many applications, so you may need to modify some hidden settings to allow tray icons.

Failing that,

It sounds like Azuereus/vuze is running in the background - possibly a dead process. You could
1) Kill the process via gnome-system-monitor, or with the "ps" and "kill" commands from the terminal
2) reboot (thus killing the process)

Thanks mycae, that solved my question.

i tried everything else but i ended up having to reboot. so i'm still wondering what made this occur and how i can prevent it in the future?

thankyou so much for your help though. golden.

so i have played around a bit:

-to begin with i could open vuze from terminal after a reboot. good.
-then i tried from the launcher. fail.
-then i searched for it in dash home, not there.
-then i looked under internet apps in dash home, it was there.
-i could open it from internet apps too but i could not get it to close and now i am left with the original error message in the terminal.

i know that to get vuze to work again all i have to do is reboot but i'd rather have it work from the launcher as it is a very useful app when it works properly. i'd also like the ability to close it without having to reboot my computer. any ideas?

thanks for your help.

just to clarify: when i say i can't get vuze to close i shut the window down but the process won't stop, when i try to use the killall command it says:

vuze: no process found

but i am left with the same error message from my initial post when i try to run the program from the terminal.

Can you give the output of:

lsb_release -a; uname -a; echo; ps -ef | grep -i vuze | grep -v grep

Thanks

sure:

toby@Manuel:~$ lsb_release -a; uname -a; echo; ps -ef | grep -i vuze | grep -v grep

>killall command it says:

Vuze/azureus is a java program, so it may be named "java", "azureus" or similar. Issuing kilall java or killall -9 java will take down *all* java applications.

that's a great fix for the meantime mycae, killall java works to stop the process although killall azureus didn't work..

as i said this will work for the time being but if in the future i begin running other java programs this fix could prove problematic....

is there a way of shutting down just the azureus process and more specifically, of making vuze work from the launcher without having to use the terminal at all?

again, i really appreciate your help as once again you've made the whole process much smoother.

thankyou,
toby

Hi Toby,

As I mentioned before, I believe that azureus is not actually broken, or even malfunctioning.

 I think it is trying to create a tray icon, which unity is hiding - as unity dropped tray icons for something called "app-inicators" ). you have to enable the tray icon from showing, or find a preference in azuereus that disables minimising to a tray icon.

I cannot be certain about the above, as I am not on your system, but this is my suspicion.

Can you give the output of the command I gave when you have the issue....

hi, sorry i haven't posted in a while, i've been away from the problematic system.... but my problem is now solved, after disovering what system tray icons actually are i was able to disable them in vuze by using options> interface, thus allowing me to run vuze like any other program, thanks for your help mycae, runs like a dream. thanks also actionparsnip for trying to help me out as well.

happy days.
