[Openchrome-users] A black screen is all I've been able to achieve. How to go on?

Sun Oct 18 13:19:25 PDT 2009

Dear Xavier,

thanks very much; this seems to offer a glimmer of hope - I first
unset the "SetPanelSize" thing and then set 

Option "ModeSwitchMethod" "new"

The behaviour was the same - a brief flicker followed by blackness -,
but the log file now contains a good deal of new things; apparently,
the driver has now been able to successfully query the card for
various technical data, such as, resolution, dimensions etc.

Thanks again and kind regards,

Florian

Again, 'diff OLD NEW' (OLD is still the file I posted):

[and, of course, please let me know if you'd prefer the whole thing]
