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.
