HDMI Handshake issue fixed

I managed to find a solution for my problem in xbmcbuntu. The command

Code:

sudo service lightdm restart

restarts the X server and reinitializes the screen. After that it works fine again.

I mapped the command to a button on my remote so I don't have to SSH in to the box everytime I get a black screen:
Find the name of the button you wish to use by typing

Code:

irw

and pressing the button. I used the "media" button on the HP (MCE) Pavillion remote.
Then

Code:

sudo nano /home/<username>/.lircrc

Add the following and save:

Code:

# Start XBMC

begin

prog = irexec

button = <name of the button you wish to use>

config = sudo /home/<username>/scripts/startXBMC.sh

end

Edit rc.local:

Code:

sudo nano /etc/rc.local

Add the following line and save:

Code:

#start IRexec

su -c '/usr/bin/irexec -d /home/<username>/.lircrc' -l xbmc

Create a file startXBMC.sh in /home/<username>/scripts/:

Code:

sudo nano /home/<username>/scripts/startXBMC.sh

And add the following lines:

Code:

#restart lightdm

sudo service lightdm restart

#restart xbmc

#killall -9 xbmc.bin

Make the script executable with:

Code:

sudo chmod +x /home/<username>/scripts/startXBMC.sh

If you want to also use this button to restart xbmc in case it crashes you'll have to remove the # on the last line.
Because the service lightdm restart command needs root access you need to start the script as sudo without having to type a password:

Code:

sudo visudo

Add:

Code:

%admin ALL=(ALL) NOPASSWD:/home/<username>/scripts/startXBMC.sh

and save.
Edit:
If your username isn't part of the admin group it won't work. You can change '%admin' to '<username>' or:

Code:

adduser <username> admin
