Re: siliconmotion CSync output ?

I think I figured it out, however it seems that although my 
modeline includes 'composite'

DisplayModePtr mode->Flags & V_CSYNC

does not evaluate to true. I assume as long as the 'composite' keyword is 
found on the modeline, the flag should be set, right ?

I need to add some debug messages, but this seems a little strange. Is 
there something else that needs to be configured, like telling that the 
driver actually supports the composite keyword on the modeline ?

On a different note, the latest X release does not seem to work on that 
chip.  I just get a blank screen. So I started hacking on Xorg 6.8.2 to 
test this stuff. I figure XFree86 4.5 should work, but 4.6 does not.

I'll provide patches to all and note on which version it was tested of 
course, once it works :-)
