====== Miscellaneous ======
Here is an unsorted collections of some findings.

  * [[linux_sound|Sound on Linux]]
===== Promiscuous mode on ThinkPad T60 =====
To enter promiscuous mode on a ThinkPad T60, a monitor device needs to be created. Follow the steps below to get it working:
<code>iw dev wlan0 interface add mon0 type monitor
ifconfig mon0 up
ifconfig mon0 promisc</code>

Now, package dumping should work on ''mon0'' and ''wlan0''. The monitor device also emits all low level WLAN packets.
===== Starting KDE if it's not the default Session Manager =====
I use to run XFCE as my windows manager on my laptop as it is fast. However, from time to time a real user interface is much nicer to use, and in this case KDE is my choice. Still, I don't want to reconfigure my system every time I want to start KDE, thus I use the following command to start it manually:
  xinit /etc/X11/Xsession startkde

(KDE does not seem to provide a start script like XFCE does on Debian.)


To reconfigure the session manager, run the following command as root and select the desired session manager.
  update-alternatives --config x-session-manager

===== Trackpoint scrolling =====

To enable trackpoint scrolling, add the following code to /usr/share/X11/xorg.conf.d/20-trackpoint.conf:
<code>
Section "InputClass"
    Identifier "Trackpoint Wheel Emulation"
    MatchProduct "TrackPoint"
    MatchDevicePath "/dev/input/event*"
    Driver "evdev"
    Option "EmulateWheel" "true"
    Option "EmulateWheelButton" "2"
    Option "Emulate3Buttons" "false"
    Option "XAxisMapping" "6 7"
    Option "YAxisMapping" "4 5"
EndSection
</code>

===== cryptroot missing after updating to Debian testing =====

After updating from Debian stable to testing, the file cryptroot in /etc/initramfs-tools/conf.d is missing. Extract it from a previous initrd and put it back. Old initrd images can be extracted using
<code>
gzip -dc /boot/initrd-XXXX | cpio -id
</code>
