I have a raspberry pi running raspbian which is started via the following line in .profile
xinit /usr/bin/chromium --kiosk --incognito www.myweb.com
however after about 10-15 mins the screen goes blank and nothing I try has managed to stop this.... However I have found a possible solution using xscreensaver. I have installed xscreensaver and then disabled it, I just now need to start xscreensaver before chromium runs.
How do I do this?
