Hi Frank,
In your situation with Wyse V90LE, it appears that OpenChrome is not able to
obtain EDID from I2C bus 1 or 2.

If OpenChrome is not able to obtain EDID via I2C bus 1 or 2, the chance of VGA
working is very slim (It is possible it can work if the manual detection
succeeds, but I have never seen this actually working.).
I do not know why EDID is not appearing on I2C bus 1 or 2 for Wyse V90LE.</pre>
