<br>
I want to configure my frontend to suspend when exit from the frontend.<br>
<br>
I make a script to shutdown this way:<br>
<br>
killall mythfrontend<br>
sudo /etc/init.d/lightdm stop<br>
sudo pm-suspend<br>
<br>
It works well, then I can resume it with a remote key.<br>
<br>
But the problem is that it doesn't show nothing in the TV. I think<br>
that it is a the nvidia driver problem.<br>
<br>
I try to "rmmod nvidia" and "modprobe nvidia" but nothing. When I<br>
start lightdm "/etc/init.d/lightdm start" it doesn't show nothing.<br>
<br>
I am using Debian Jessie with Nvidia 340.65.<br>
<br>
Anyone use to suspend nvidia frontends?<br>
<br>
Thanks for your help.<br>
<br>
Best regards.<br>
