Newbie help: Cmake errors & Changing the mouse's dpi

Xert · 08-22-2008, 01:06 PM

Hey there, new to Debian and I've run into several difficulties. I'm running KDE4.1 on Lenny.

1. I can't change the dpi of my mouseman dual optical for non-root users. Apparently it's a permissions problem, but the instructions in the KDE help file didn't change anything.

Code:

Fixing permission problems on Logitech mice
 Because of the way USB devices work, the code that accesses the current status on Logitech mice needs to be able to write to the mouse. This should be handled by your distribution, but if not, you may need to do some configuration yourself. 
 On a Linux system, you should use the hotplug system to change the ownership and permissions on the mouse entry in /proc/bus/usb. One way to do this is to create a short script (/etc/hotplug/usb/consoleUserPerms) that changes the ownership and permissions, as shown below: 

#!/bin/bash
#
# /etc/hotplug/usb/consoleUserPerms
#
# Sets up newly plugged in USB device so that the user who owns
# the console according to pam_console can access it from user space
#
# Note that for this script to work, you'll need all of the following:
# a) a line in the file /etc/hotplug/usb.usermap or another usermap file
#    in /etc/hotplug/usb/ that corresponds to the device you are using.
# b) a setup using pam_console creates the respective lock files
#    containing the name of the respective user. You can check for that
#    by executing "echo `cat /var/{run,lock}/console.lock`" and
#    verifying the appropriate user is mentioned somewhere there.
# c) a Linux kernel supporting hotplug and usbdevfs
# d) the hotplug package (http://linux-hotplug.sourceforge.net/)
#
# In the usermap file, the first field "usb module" should be named
# "consoleUserPerms" to invoke this script.
#

if [ "${ACTION}" = "add" ] && [ -f "${DEVICE}" ]
then
# New code, using lock files instead of copying /dev/console permissions
# This also works with non-kdm logins (e.g. on a virtual terminal)
# Idea and code from Nalin Dahyabhai <nalin@redhat.com>
    if [ -f /var/run/console.lock ]
    then
        CONSOLEOWNER=`cat /var/run/console.lock`
    elif [ -f /var/lock/console.lock ]
    then
        CONSOLEOWNER=`cat /var/lock/console.lock`
    else
        CONSOLEOWNER=
    fi
    if [ -n "$CONSOLEOWNER" ]
    then
        chmod 0000 "${DEVICE}"
        chown "$CONSOLEOWNER" "${DEVICE}"
        chmod 0600 "${DEVICE}"
    fi
fi


 The usermap file that goes with this is /etc/hotplug/usb/logitechmouse.usermap, as shown below:

 That should be all that is needed on Linux - just copy the files into /etc/hotplug/usb/, and when the mouse is plugged in, the ownership and permissions should be changed so that the user at the console can access the mouse.

2. Cmake doesn't want to work. I installed it via apt-get, but using it returns this message:

Welcome to Linux Questions.

add 2.
Well, you get all these errors, when 'cmake'
cannot find anything.
You must have a "build directory" outside
the top - directory of the application.

a) you have "/home/xert/lancelot" and
b) a build : /home/xert/build-lancelot

To make the stuff : 1) 'cd build-lancelot'
2) 'cmake ../lancelot/' => pay attention <= EDIT !
to the 2 dots, to get the path to "lancelot"
3) 'make' ... 'su' ... 'make install'

As non of your questions are Debian specific,
I will suggest starting a new thread with
the mouse issue in "Linux > Hardware"

Good Luck !

P.S.: There is a package for lancelot :
http://c.imagehost.org/download/0430...817-1_i386.deb

I am sorry, made a print error :

'cmake ../lancelot/' is correct.
