[RaspPi] Trouble with xfce4-panel on Kali Linux

Errors with xfce4-panel

I got an error that the xfce4-panel / Taskbar disappeared.
I solved it by right-clicking on the Desktop, choosing Applications, Settings, Panel.
After that it told me that it got no panel running, and if it should start one.
I answered yes and the panel would appear again.

After an reboot, I always got the question wheter it should start an panel.
As that was quite annoying, I looked for another solution to the problem.
I found the answer here: http://forum.ubuntuusers.de/topic/probleme-mit-panel-und-kiosk-modus/
Just delete the xfce settings like that:
rm -rf ~/.cache
rm -rf ~/.config

After that, click the log out button, UNCHECK the "Save session for future logins" box and choose reboot.

On the next reboot, it should come up correctly again.

[RaspPi] Install Kali Linux on RPi with HDMIPi

1.) Download Kali for RPi
https://www.offensive-security.com/kali-linux-vmware-arm-image-download/

2.) Extract if with 7zip, format your SDCard with the Formatter from the SDCardAssociation and write the Image (kali-1.0.9-rpi.img) to your SD Card

2b.) If you plan on using Kali with your HDMIPi Screen, create an config.txt file with following content on the sdcard to have correct HDMI sizing:

hdmi_ignore_edid=0xa5000080
hdmi_group=2 # HDMIPi for 1280 x 800
hdmi_drive=2 # for alternative modes get sound
hdmi_mode=28 # 1280 x 800 @ 60 Hz Specifcations

3.) Boot it

4.) After boot, login with root / toor

5.) Install raspi-config using the terminal
wget https://raw.githubusercontent.com/snubbegbg/install_raspi-config/master/install.sh
chmod +x install.sh
sudo ./install.sh

6.) Configure sdcard reseize, locale and stuff using sudo raspi-config and reboot

7.) Install Kali Metapackages
Kali comes kind of "blank" with no tools.
Choose your needed package from https://www.kali.org/news/kali-linux-metapackages/ and install it using apt-get.
But please look out for the installation size!
I.e. for the kali-linux-top10 package:
apt-get update
apt-get install kali-linux-top10
Or the complete ISO package (9 GB!):
apt-get install kali-linux-full

8.) Reboot
sudo reboot

9.) After rebooting and login with root / toor, enter startx to use Kali
