Perhaps this is more a Xorg question, but I try it here.
I would like to completly disable the automatic screen configuration. Display should always happen on the same output (HDMI) even if the monitor is not on and independent from what the monitor tells that it is able to display. The graphic chip is the Intel HD 4000.
I have tried to write an xorg.conf with a correct modeline but even then different modes a probed and a lower refresh rate is choosen.
I think it sould be a simple thing to disable all this DAU automatic and configure the vales by hand. But even the supported parameters of the xorg.conf depends on the graphic driver.
Is there a better solution than download the source code, modify the source code and build the server myself?
