I have a GeForce connected to the monitor and to the TV. I want the TV only to play videos so I don't want any window manager in it.
By default with Mandrake KDE starts on both screens, and I need help to make it only start in monitor.
X is configured to use a single session with two screens, :0.0 and :0.1.
Looking at startkde script there are two interesting lines:
LD_BIND_NOW=true kdeinit +kcminit +knotify
kwrapper ksmserver $KDEWM
Looking at help, ksmserver supports "--display" but kdeinit doesn't.
And there are two interesting environtment variables but that I don't know exactly what they do and where are set:
After starting KDE, KDE_MULTIHEAD is set to true and KDE_DISPLAY isn't set. KDE_DISPLAY perhaps is no used anymore on KDE 3.x....but not sure.
I have tried a lot of options with different results, but not a good one. Setting the --display for ksmserver seems to partially work, there are some "kxxx" that are only executed one time, but others like kicker are still executed two times....probably because kdeinit has not specified anywhere the display screen.
Well...all this isn't of much help
but if someone has experience with this sitaution or has any idea would be apreciated.
And anyway, someone knows if screen :0.1 can be shutdown temporally in a way I can use the main monitor normally, and activate the second (TV) screen only when I want to watch a video?
