Description Arnt Gulbrandsen 2002-07-11 16:16:34 UTC
(*** This bug was imported into bugs.kde.org ***)

Package: konsole
Version: 2.1 (and various newer versions - this machine is old)

Konsole writes to /dev/ptmx very often. This means that the mtime of
/dev/ptmx keeps changing and consequently the disk has to keep spinning.
Bad for laptops.

Hi Arnt

Long time no see :-)

/dev/ptmx is the terminal device used by konsole to communicate with the=20
shell so it's sort of hard not to write to it.

Which distro / kernel are you using?

xterm doesn't ;) Since I quit using konsole my laptop is silent and cool.

ISTR a /dev/[pt]ty* pair is used for communicating with the shell.
/dev/ptmx is used to manage the [pt]ty pair. If I've understood it
correctly konsole must write to ptmx on startup but not every ten
seconds.

On this laptop: caldera 3.1. Custom 2.4.17.

Not a bug intended system behaviour.

Beg^H^H^HAsked kernel-gods for a fix.
