Cannot close frozen Konqueror

[Rayson]

We have a Dapper machine with 8 instances of Konqueror running (or are they frozen). We cannot close them or do most anything with them except minimize them. When we reboot, the 8 instances are there.

We can start a new copy of Konqueror and it works fine.

Can anyone tell us how to close these frozen instances please?

As default Kubuntu (KDE) will:

Restore previous session
Will save all applications running on exit and restore them when they next start up.

Dapper:
K > System Settings > KDE Components > Session Manager > On Login: Restore previous session / Restore manually saved session / Start with an empty session.

Killing processes:
Ksysguard
Press: Ctrl+Esc -> choose prosess -> press kill
or
K>System>ksysguard
or
Press Alt+F2 -> type ksysguard


In the konsole:

Use ps (to get konqueror prosess id's) and kill commands

man ps:

PS(1) Linux User’s Manual PS(1)

NAME
ps - report a snapshot of the current processes.

SYNOPSIS
ps [options]

DESCRIPTION
ps displays information about a selection of the active processes. If
you want a repetitive update of the selection and the displayed
information, use top(1) instead.

man kill:

KILL(1) Linux User’s Manual KILL(1)

NAME
kill - send a signal to a process

SYNOPSIS
kill [ -signal | -s signal ] pid ...
kill [ -L | -V, --version ]
kill -l [ signal ]

DESCRIPTION
The default signal for kill is TERM. Use -l or -L to list available
signals. Particularly useful signals include HUP, INT, KILL, STOP,
CONT, and 0. Alternate signals may be specified in three ways: -9
-SIGKILL -KILL. Negative PID values may be used to choose whole pro‐
cess groups; see the PGID column in ps command output. A PID of -1 is
special; it indicates all processes except the kill process itself and
init.

=> Example:

:~$ ps -e | grep konqueror

6655 ? 00:00:00 konqueror
7362 ? 00:00:02 konqueror
7411 ? 00:00:00 konqueror

:~$ kill 6655

:~$ ps -e | grep konqueror

7362 ? 00:00:02 konqueror
7411 ? 00:00:00 konqueror

Thank you very much for your great help. Based on your information we were able to solve the problem and also learn more about Kubuntu. We are using 22 Daper machines here in Nepal to teach computer skills.
