[Openchrome-users] 720x576Noscale problem

[Jóhann Þórir Jóhannsson]

Hi and thank you for the Openchrome effort.

Gear:  SP13000 (CN400).
   Xorg 7.0, Openchrome 20060306, Tv-out in PAL over S-video. Gentoo 
based EpiOs with kernel 2.6.15.

I've tried 720x576 mode but with picture too far to the right and too 
far down, 800x600 is OK but with small black border and blurry, 
720x576Over is clear and crisp but with big parts of the screen missing 
(notably the [cancel]    [<prev] [next>] bottom line in MythTv configs 
is lost), it is also too far right and down (by about I guess 5-10%)

The 720x576Noscale is very crisp but seriously garbled and in b/w.  
Looks like two, three images superimposed, with one far right, and two 
almost overlapping.

Any advice on getting the Noscale mode working, can't figure out these 
modeline thingies...

Is there a utility that can adjust these things in real time without 
restarting X? I tried Xvidtune, but it holds the pixel clock so the 
vertical refresh rate changes, it is also unusable when the screen is 
garbled as you can't see which button to click.

I swore I wouldn't cut my hair or shave until I got this thing up and 
running. I now have a full beard and hippy hair.
