Kernel and PTYs

phi · 2005-09-28 19:40:23

I have a problem with PTYs. Because i use a custom build of 2.6.10 kernel, i suppose I've configured something badly. For example: "screen" refuses working, and prints "No more PTYs. Sorry, could not find a PTY". xterm and all other X consoles also don't work.
I've tried to enable Device Drivers->Character Devices->Legacy (BSD) PTY support, but it still doesn't work.

Should I enable PTY support somewhere else, or do I need to enable some additional features?

you have to mount.... ummm "ptys" or something like that via fstab... I don't have a reference on me right now, but if someone can post the output of "grep pty /etc/fstab" that'd be great.

I assume you mean this line:

none                    /dev/pts        devpts          defaults                0       0

Thanks a lot. It works

I have a similar problem:

jo:~$ aterm
aterm: can't open pseudo-tty
aterm: aborting
jo:~$ mrxvt
mrxvt: can't open pseudo-tty
jo:~$ urxvt
urxvt: can't initialize pseudo-tty, aborting.
jo:~$ gnome-terminal 
<gives popup: "A problem occured when trying to open a subprocess for this terminal.">

jo:~$

None work. Xterm and screen both work, though.

From /etc/fstab:

# Lots of crap here
none                   /dev/pts      devpts    defaults            0      0
# ...

Now i wouldn't be complaining too much about this if vim didn't suck so much in xterm. Something is really wrong.

Bleurgh, you're very right about vim in xterm.
I had a similar problem (it started when I went to runlevel 1 and back) and fixed it by running

#mount /dev/pts

manually. Suddenly aterm, terminal, xterm, mlterm and screen all started working (I know, pacman -R is sadly underused), and /dev/pts started being populated.
Gnome-terminal required a gnome restart though.
