due to a valuable hint of Alejandro and a hint of Richmond to that hint we have now a solution for making windowshape work with LC 6.5.1 and 7.0.4 on Raspi.
The attached image was done just now with a "windowShape" in LC 6.5.1 on a Raspi B stack I prepared for the time when windowshape will work. Now it's possible.
[Edit. After first crashes and some improvements it works now, see "Shaped RaspiStack #2" below.]
Here are the instructions:
Use the Terminal of your Raspi.
 sudo apt-get install xcompmgr
 cd /etc/xdg/autostart/
 sudo nano Xcompmgr.desktop
Then copy and paste the following.
Code: Select all
[Desktop Entry] Encoding=UTF-8 Name=XCompmgr Comment=XCompmgr--our compositor Exec=xcompmgr Terminal=false Type=Application OnlyShowIn=XFCE;LXDE
 sudo reboot
You are done.
WOW! Several stacks will now run on Raspi. What a wonderful weekend!
I'll post some stacks using windowshape as soon as I have them working.
Thanks Alejandro and Richmond!
