Description Rob Smith 2005-10-22 19:04:10 UTC 
Version:           1.6 (using KDE 3.4.92 (beta2, >= 20051010), Gentoo)
Compiler:          gcc version 3.4.4 (Gentoo 3.4.4-r1, ssp-3.4.4-1.0, pie-8.7.8)
OS:                Linux (i686) release 2.6.14-rc4

randomly every so oftern the bash in the knosole tab 'freezes' and just buffers all input and it unfreezes randomly and all the input is sprewed out. Konsole as a app doesn't freeze, and sometimes a certain tab will freeze and all the rest are fine.

They close fine and everything. Is there anything I could do to help you track this one down?

Thanks!

You can see what strace says that bash is doing.

% ps | grep bash

% strace -p ####

I confirm the problem. I'm running Slackware 10.2 with kde 3.4.2 and konsole 1.5.2. Input randomly freezes in tabs. I have noticed that this problem appears only when i'm using the 2.4.31 kernel, and magically disappears when using 2.6 series kernel.

I'm running 2.6.x (x==14 at the moment). I have not been able to get the strace yet. it's been behaving when I don't want it to. Maybe you (George that is) can get a strace?

Not sure why it cut my comment out, but I was saying, I run 2.6.x (x=14 at the moment) and it's been doing it for awhile for me under 2.6.x. I have not had the chance to get a strace yet, it's been behaving when I don't want it to. Maybe you (George that is) can get a strace?

You folks are not running xine, are you?
Comment 6 Rob Smith 2005-11-04 20:52:36 UTC 
I do indeed. to play dvd's.

Is this a known issue?

I shall test with xine later tonight.
Comment 7 Rob Smith 2005-11-05 03:58:40 UTC 
I have to say, I'm surprised.

It's been awhile from the last time it froze on me. It worked fine all day today, then I launched xine and a little while later, it froze up.

How in the world is xine causing this?
Comment 8 Rob Smith 2005-11-05 04:08:44 UTC 
This is very odd

I attached strace to both the konsole and the bash spawned from the konsole. When it is 'frozen' both bash and konsole are receiving keystrokes, the screen just doesn't get updated...

Any thoughts?
Comment 9 Maksim Orlovich 2005-11-05 04:18:53 UTC 
Xine is sending applications scroll lock presses (to simulate activity, so the screensaver doesn't kick in). Try pressing the key yourself --- it should unfreeze the terminal. [And because of the way it's doing it, I don't think konsole can tell it's synthetic]. There were some discussions on the xine list about trying to fix how that works...

And, well, I found that out on my own skin ;-)

xine related
