Audacity freezes at startup and its logo remains frozen in the screen

Post by [email protected] » Thu Feb 27, 2020 1:47 pm

Hi! I'm having the same issue on xubuntu.

My environment is audacity/bionic,now 2.2.1-1 amd64, Xubuntu based on Ubuntu 18.04.4 LTS, kernel 4.15.0-88-generic.

It's kind of weird because if I run Audacity right after the computer starts, it runs fine. If I close it and try it to run it again, it freezes and the logo remains frozen. The process wont die with ctrl-c or kill -9

I have tried, without any luck, the solution in this thread: viewtopic.php?f=48&t=107814

This is the console log when I run it right after the computer starts. You can see at the end that I have tried to run it again but it does not show any log messages, that's where it freezes

Code: Select all

 I'm having the same issue on xubuntu.
I've split this from the other topic because the problem you describe is only superficially the same as the other topic (similar, but distinctly different symptoms).

Why is your command prompt "localhost"? Are you running Audacity on a server?

 Hi! I'm having the same issue on xubuntu.

My environment is audacity/bionic,now 2.2.1-1 amd64, Xubuntu based on Ubuntu 18.04.4 LTS, kernel 4.15.0-88-generic.

It's kind of weird because if I run Audacity right after the computer starts, it runs fine. If I close it and try it to run it again, it freezes and the logo remains frozen. The process wont die with ctrl-c or kill -9

I have tried, without any luck, the solution in this thread: viewtopic.php?f=48&t=107814

This is the console log when I run it right after the computer starts. You can see at the end that I have tried to run it again but it does not show any log messages, that's where it freezes

Code: Select all

That is nonetheless interesting. I post the very similar terminal message that was generated on the one occasion that I did get Audacity to rune on Mint XFCE 19.3:

 I'm having the same issue on xubuntu.
I've split this from the other topic because the problem you describe is only superficially the same as the other topic (similar, but distinctly different symptoms).

Why is your command prompt "localhost"? Are you running Audacity on a server?
I'm using my laptop/desktop, not a server

 Hi! I'm having the same issue on xubuntu.

My environment is audacity/bionic,now 2.2.1-1 amd64, Xubuntu based on Ubuntu 18.04.4 LTS, kernel 4.15.0-88-generic.

It's kind of weird because if I run Audacity right after the computer starts, it runs fine. If I close it and try it to run it again, it freezes and the logo remains frozen. The process wont die with ctrl-c or kill -9

I have tried, without any luck, the solution in this thread: viewtopic.php?f=48&t=107814

This is the console log when I run it right after the computer starts. You can see at the end that I have tried to run it again but it does not show any log messages, that's where it freezes

Code: Select all

localhost:~$ audacity --test

That is nonetheless interesting. I post the very similar terminal message that was generated on the one occasion that I did get Audacity to rune on Mint XFCE 19.3:

Yep! And it's also very similar to the issue described on this other thread: viewtopic.php?f=48&t=106751

Update from my 1st post:

The second time a ran the command audacity --test I thought it was hung forever, I was wrong. This is the console log:

Code: Select all

I want to add that this problem started when I upgraded to xubuntu 14.04.6 LTS to 18.04.4 LTS.

All other audio applications are working fine. Also, as suggested on this thread (viewtopic.php?f=48&t=107814&start=10#p382214), I installed/tested gnome-sound-recorder and it works fine.

How did your mistake happen? Did it appear to hang for a while before continuing? If so, how long for?

I left the terminal window unattended for a while before noticing that the process finished, maybe 30 mins to 1 hr, I don't know for sure.

Also, at some point I xkill-ed the logo splash screen (it was freeze at the middle of the monitor), that may be the cause of the error: "audacity: Fatal IO error 2 (No such file or directory) on X server :0.0."

Please time it. Cause the freeze, then keep your eye on the terminal for 5 minutes, then if it has not crashed, do something else for an hour but check the terminal every 5 minutes to see if it has crashed.

That will cause Audacity to crash.

At the moment, I have a fuzzy mental picture of Audacity freezing for a while on launch, and then possibly crashing, or possible being killed, and at some point during that, some messages appear in the terminal. This mental picture is too fuzzy to give any clues as to what the problem is. A clear picture of exactly what is happening, "may" give a clue as to what the cause is (or may not).
