Booting problem with VGA splitter
Posted: 15 Jul 2015, 19:23
Hi All,
I'm using Porteus-Kiosk for signage applications and it works very well, but now i got a little problem.
I want to control two VGA displays simultanously, via an active VGA splitter.
The desired settings are 1024x768, 24bit, 60Hz. In the Porteus-Kiosk wizard I set the lines below:
screen_refresh_rate=60
screen_resolution=1024x768
It starts up well if I connect only one display. It also works if I start up the system with one display, then connect the VGA splitter.
But if I want to start it up with the connected VGA splitter and two displays, it breaks down when the GUI starts to loading. After this, I cannot catch the signal with one monitor or two, it doesn't work.
The listed settings are maximums, so maybe Linux checks something at startup and the splitter makes a measurement mistake, so that it sets incorrect resolution or freq.
Is there a way to skip this check at startup and set these properties directly?
Thanks in advance!
