Hi Kevin 



First thanks for your efforts and congratulations for the new version. 



I
 have tested it (commit 52730d1) on an HP T5550 (VX900) device but unfortunately there is
 still no signal on non-LCD (ie. crt-tube) VGA monitors connected trough
 DVI-VGA adapter. I have also tested it on CLE266, CN700 and VX800 
devices. There is no problem on them. Actually I wonder if you or anyone
 else tested VX900 with a crt-tube monitor. Because time to time I have tested some previous commits but could never have a signal. (Comment # 248)


Please note that crt monitor works with via-opensource driver on VX900. But
 it seems that its kind of faking EDID data. Because although it can 
detect the VGA monitor, it supports only 60Hz on all resolutions unless 
there is Modeline settings in xorg.conf file. Also there is "Monitor 
name: S3FakeEdidCRT" message seen on xorg log file. 



I can send xorg 
log files of five different tests I have performed via e-mail or open a new bug. 
Please let me know which one you prefer. By the way, IMHO, if you do not have any, having a tube monitor for your own tests will be the best for future works as probably there is still many people using these old monitors 
together with their old VIA devices. 

John
