Description
Created attachment 122797 xorg.log files of Openchrome 0.4.0 (VX900, CLE266, CN700, VX800) and via-opensource (VX900) tests w/ VGA (crt) monitor
Using Openchrome 0.4.0, non-LCD (ie. crt-tube) VGA monitors connected to HP T5550 (VX900) trough DVI-VGA adapter can not be detected and there is no signal. (Tested with multiple monitors and VGA-DVI adapters.)
There is no problem with CLE266, CN700 and VX800 devices I have tested. But I know that its a different story as they all have native VGA ports.
I have also tested via-opensource driver on VX900 and there is no problem getting image on crt monitor using DVI-VGA adapter. But it seems that this driver kind of faking EDID data. Because although it can detect the VGA monitor, it supports only 60Hz on detected resolutions unless there is Modeline settings in xorg.conf file. Also, the message "Monitor name: S3FakeEdidCRT" seen on xorg log file implies this.
Attached are zipped xorg.log files of above menioned tests. Files renamed accordingly.
