[gentoo-user] screen, mc, htop

[gentoo-user] screen, mc, htop

[András, Csányi - Sayusi Ando]

Hi all!

I'm here again.

So, the problem points is I can't decide what is the real problem. But
I can describe the symptomes.

I use screen lot of and I like it veery much. Few weeks ago - when I
reinstall gentoo, started this weird thing.
If I start mc in the screen nothings happen. I can see the cursos is
stop before the last line and waiting...
Generally first time the mc is start and I can work with. But, random
long time later the mc is start doing this stupid behavior what I
wrote upper. This thing is independent what I did. Last time is
started after I use vim to edit an file. Yesterday started after I
write in mc's command line 'df -h' and hit Enter.

If I detached screen I can start an mc. So, mc is working. If I
straced the process what is waiting I can see only this in the outline
of strace:

"read(0,"

In the screen I can't interrupt the process with Control-c or
Control-d. I can kill this process with C-a K but in this case the
screen windows will die too.
The screen do this with users and root user too. The 'screen -wipe'
command isn't solution. About my experiences the reboot is the
solution, only...

The important informations:
app-misc/screen-4.0.3 multiuser nethack pam -debug -selinux
app-misc/mc-4.6.2_pre1 7zip gpm ncurses nls -samba slang unicode -X

This information is enough or do you need more?

But there is an another crazy thing.
If I start htop - after the mc and screen started doing the strange
behavior - nothing happen. I detouch the screen and touch back the
htop is working fine.

I hope somebody can tell me what is the problem because I don't know. :(

Thank you!

Very strange. I just tried this combination and it all works for me.
Here's my versions (am on ~amd64)

app-misc/screen-4.0.3  USE="pam -debug -multiuser -nethack (-selinux)"
app-misc/mc-4.6.2_pre1  USE="X gpm nls samba unicode"
sys-process/htop-0.8.1-r1  USE="unicode -debug"

I do not use "multiuser" or "nethack" USE flags for scren. You do not
use "samba". Otherwise everything seems the same.

This is a very old post, but I want to say I am experiencing the same
problems with screen and mc (even after I initially replied saying I
didn't have it :). Did you ever find a solution?

I dunno if my problem is the same as yours, but it may not be just mc.
screen has been crapping out on me lately, and also randomly, like
described above, when I use some of the shell scripts that I wrote. It
only happens with interactive scripts that display a menu using
'dev-util/dialog'. Most of the time it works, sometimes it doesn't:
after the previous dialog clears the screen, screen just sits there
blinking and not loading the next one. 

I'd be interested in a solution too, if there is one.

If you start screen, then do "export TERM=xterm", does that fix the issues?

So far that seems to fix it for me! But it's a very random and
non-reproducible error so only time will tell. mc froze on startup for
me just now (with TERM=screen) 5 times in a row; set TERM=xterm and mc
started without problem 5 times in a row. So that's a good sign, I
think.

Thanks!

I use that trick to get mouse support in mc under screen.  Just thought 
it might solve even more issues.

I remember fixing a problem which may be related to this, by cp /etc/screenrc 
~/.screenrc and then editing ~/.screenrc to add lines like:

  termcap  rxvt hs@:cs=\E[%i%d;%dr:im=\E[4h:ei=\E[4l
  terminfo rxvt hs@:cs=\E[%i%p1%d;%p2%dr:im=\E[4h:ei=\E[4l

under 'xterm tweaks'; this is because echo $TERM shows that my terminal is 
rxvt - yours may be different.
