Connor Behan <[email protected]> changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #99694|0 |1 is obsolete| | --- Comment #21 from Connor Behan <[email protected]> --- Created attachment 99793 --> https://bugs.freedesktop.org/attachment.cgi?id=99793&action=edit Patch with detection I could not find changes to hardware state before and after the vbe stuff but I found an easier way to detect monitors. That is a simple call to xf86I2CProbeAddress(). In other words, xf86DoEDID_DDC2() was getting far enough to tell that there was a monitor. It only returned NULL because it was not getting a valid EDID. Detecting the valid modes with EDID would be nice, but I think this solves the most important problem. The driver now knows whether a monitor is plugged in and hence whether to drive Crtc2. If you agree, I will send this patch to the list. -- You are receiving this mail because: You are on the CC list for the bug.
